Does the presence of radiculopathy affect sleep quality and lower extremity functionality in neuropathic low back pain?

SUMMARY OBJECTIVE: Sleep disturbance in chronic neuropathic low back pain is a well-known condition. In this study, we aimed to investigate the effect of lumbar radiculopathy on sleep quality and lower extremity functionality in the presence of neuropathic low back pain. METHODS: A total of 79 patients diagnosed with disk herniation, needle electromyography, and neuropathic pain were included in the study. Visual Analog Scale, Pittsburg Sleep Quality Index, and Lower Extremity Functionality Scale were applied to the patients. RESULTS: Of the 79 patients who participated in the study, 34 (43%) were females and 45 (57%) were males. No significant difference was found between the group with and without radiculopathy in terms of sleep quality and lower extremity functionality (p=0.245 and p=0.092, respectively). In our study, a negative correlation was found between night pain and the presence of radiculopathy (p=0.006). The number of lumbar herniated disk levels was higher in the group without radiculopathy and was statistically significant (p=0.023). CONCLUSION: We found that the presence of radiculopathy did not affect sleep quality and lower extremity functionality in disk herniation patients with neuropathic pain. Although it was not statistically significant in our study, we think that the degree of herniation may affect sleep and lower extremity functionality rather than the number of disk herniation levels with the available data. The fact that neuropathic pain is not limited to disk herniation and radiculopathy, and that neuropathic pain is intertwined with clinical conditions such as anxiety, sleep disorders, and depression are among the conditions that make the studies difficult.

Analysis of Animal Models of Cervical Spondylotic Radiculopathy Based on Characteristics of Clinical Symptoms of Chinese and Western Medicine / 中国实验方剂学杂志

With the acceleration of social rhythm， the progress of science and technology， and the increase of the number of phubbers， the incidence of cervical degenerative diseases is also increasing year by year. Cervical spondylotic radiculopathy（CSR）， as one of the diseases induced by cervical degeneration， has seriously affected people's quality of life and physical and mental health. Traditional Chinese medicine（TCM） is effective in the treatment of CSR， but the theoretical and basic experimental evidence is not sufficient， and the current formulation standard of animal model is not unified. Therefore， based on the clinical guidelines of Chinese and Western medicine for CSR and the characteristics of the disease and syndrome， the author systematically summarized and analyzed the existing animal models， and found that the existing models of microvascular clamp nerve root compression method had a poor agreement with the the Chinese and Western medical guidelines， while the modeling methods of spinal canal insertion， autologous bone insertion compression， stainless steel column compression， and fixed frame cervical degeneration reflected a high degree of agreement in the Western medical guidelines. However， the Chinese medical diagnostic criteria were poorly matched. This indicates that the existing animal models of this disease show few TCM syndrome elements， and lack information collection and evaluation in animal behavioral evaluation similar to the four diagnoses of TCM. In conclusion， this paper aims to systematically evaluate the current status of animal model establishment of CSR based on the concept of combination of disease and syndrome， so as to provide a theoretical basis for the model establishment of CSR that is more consistent with clinical characteristics and symptoms of Chinese and Western medicine.

Comparative analysis of clinical efficacy between posterior percutaneous endoscopic discectomy and anterior cervical discectomy and fusion in the treatment of cervical spondylotic radiculopathy / 中国骨伤

OBJECTIVE@#To explore the clinical efficacy of posterior percutaneous endoscopic discectomy(PPECD) in the treatment of cervical spondylotic radiculopathy.@*METHODS@#A total of 56 patiens with single segment cervical spondylotic radiculopathy from December 2017 to October 2020, were randomly divided into observation group and control group. In observation group, there were 16 males and 11 females, including 8 cases of C4,5, 13 cases of C5,6 and 6 cases of C6,7 performed posterior percutaneous endoscopic discectomy, aged from 34 to 61 years old with an average of (51.15±6.29) years old. In control group, there were 19 males and 10 females with single segment cervical spondylotic radiculopathy including 10 cases of C4,5, 14 cases of C5,6 and 5 cases of C6,7 performed anterior cervical discectomy and fusion, aged from 40 to 65 years old with an average of (53.24±5.31) years old. The operative time, intraoperative blood loss, postoperative time of lying in bed and length of postoperative hospital stay were recorded. Visual analogue scale(VAS) and neck disability index(NDI) were used to evaluate the clinical efficacy. Cervical plain films or MRIs, CTs were taken for re-visiting patients.@*RESULTS@#All patients were followed up more than 2 years. The observation group patients were followed up, the duration ranged from 24 to 42 months with an average of (30.48±4.91) months. The control group patients were followed up, the duration ranged from 25 to 47 months, with an average of (32.76±4.53) months. Compared with control group, operative time, intraoperative blood loss, postoperative time of lying in bed and length of postoperative hospital stay were decreased(P<0.05). Compared with pre-operation, VAS of neck and upper limb and NDI at the latest follow-up between two groups were significantly improved(P<0.05). Compared with control group, VAS of neck and upper limb at 1 day after operation in observation group were significantly reduced(P<0.05). There was no significant difference in VAS of neck and upper limb and NID at 1, 3 months and the latest follow-up after operation between two groups(P>0.05). In the observation group, one patient's deltoid muscle strength was weakened to grade 4 after operation, and returned to normal after 12 weeks of conservative treatment. In control group, there was 1 case of postoperative adjacent spondylosis with symptoms of spinal compression after 2 years operation, then underwent cervical artificial intervertebral disc replacement. And there was 1 case of dysphagia after operation in control group and improved after 1 year. There was no significant difference in incidence of complications between two groups.@*CONCLUSION@#PPECD has advantages of shortening operative time, decreasing intraoperative blood loss, reducing postoperative time of lying in bed and length of postoperative hospital stay. However, applicable age range of patients and long-term clinical efficacy needs further study.

Causes of asymptomatic side limb pain after minimally invasive transforaminal lumbar interbody fusion / 中国骨伤

OBJECTIVE@#To investigate possible causes and preventive measures for asymptomatic pain in the limbs after minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF).@*METHODS@#Clinical data from 50 patients with lumbar degenerative disease who underwent MIS-TLIF between January 2019 and September 2020 were retrospectively analyzed. The group included 29 males and 21 females aged from 33 to 72 years old, with an average age of (65.3±7.13) years. Twenty-two patients underwent unilateral decompression, and 28 underwent bilateral decompression. The side(ipsilateral or contralateral) and site(low back, hip, or leg) of the pain were recorded before surgery, 3 days after surgery, and 3 months after surgery. The pain degree was evaluated using the visual analogue scale(VAS) at each time point. The patients were further grouped based on whether contralateral pain occurred postoperatively (8 cases in the contralateral pain group and 42 in the no contralateral pain group), and the causes and preventive measures of pain were analyzed.@*RESULTS@#All surgeries were successful, and the patients were followed up for at least 3 months. Preoperative pain on the symptomatic side improved significantly, with the VAS score decreasing from (7.00±1.79) points preoperatively to (3.38±1.32) points at 3 days postoperatively and (3.98±1.17) points at 3 months postoperatively. Postoperative asymptomatic side pain (contralateral pain) occurred in 8 patients within 3 days after surgery, accounting for 16% (8/50) of the group. The sites of contralateral pain included the lumbar area (1 case), hip(6 cases), and leg (1 case). The contralateral pain was significantly relieved 3 months after surgery.@*CONCLUSION@#More cases of contralateral limb pain occur after unilateral decompression MIS-TLIF, and the reason may include contralateral foramen stenosis, compression of medial branches, and other factors. To reduce this complication, the following procedures are recommended: restoring intervertebral height, inserting a transverse cage, and withdrawing screws minimally.

With the effects of activating blood and resolving stasis, and moving Qi to relieve pain, Jingtong Granules is widely used in the treatment of cervical radiculopathy in China. Long-term clinical application and related evidence have shown that the prescription has ideal effect in alleviating the pain in neck, shoulder, and upper limbs, stiffness or scurrying numbness, and scurrying pain caused by this disease. However, there is a lack of consensus on the clinical application of Jingtong Granules. Therefore, clinical first-line experts and methodology experts from all over the country were invited to compile this expert consensus. This expert consensus is expected to guide clinicians to use Jingtong Granules in a standardized and reasonable way, improve clinical efficacy, reduce medication risks, and benefit patients. First, according to the clinical experience of experts and the standard development procedures, the indications, syndrome characteristics, clinical advantages, and possible adverse reactions of Jingtong Granules were summarized. Then, through face-to-face interview of clinical doctors in traditional Chinese medicine and western medicine and survey of the clinical application, the clinical problems were summed up, and the consensus was reached with the nominal group method to form the final clinical problems. Third, evidence retrieval was carried out for the clinical problems, and relevant evidence was evaluated. The GRADE system was employed to rate the quality of evidence. Fourth, 5 recommendation items and 3 consensuses items were summarized with the nominal group method. Opinions and peer reviews on the consensus content were solicited through expert meetings and letter reviews. The final consensus includes the summary of evidence on the clinical indications, effectiveness, and safety of Jingtong Granules, which can serve as a reference for clinicians in hospitals and primary health institutions.

Acute radiating low back pain impact on routine and function of the brazilian population: a cross-sectional study / Impacto da lombociatalgia aguda na rotina e função da população brasileira: um estudo transversal

ABSTRACT Acute radiating low back pain is a frequently occurring clinical condition among the population, and it represents a significant portion of urgent care in public health services. Objective: Consider the clinical characteristics, demographics, as well as the intensity of the pain, discomfort, and dysfunction of patients who show a clinical diagnosis that is compatible with acute radicular pain, new or reoccurring after an asymptomatic period. Methods: Patients that display a clinical diagnosis that is compatible with acute sciatic nerve pain, with the beginning of it starting within three months, without previous history of a similar occurrence, were seen in an orthopedic health clinic from July 2020 to January 2021. Results: A total of 42 patients were seen with a compatible diagnosis, which represents 1.4% of all medical visits. To the best of our knowledge, no studies have considered the clinical and demographic characteristics of patients with acute radicular pain in the Brazilian population. This study has found a mean value on the disfunction index that is greater than what is suggested by the current literature. Conclusion: About 30% of individuals showed functional involvement that was considered crippling, which presented a stronger association with individuals with the presence of motor deficits, intensity of radiating pain, and professional inactivity. Level of Evidence IV, Cross-Sectional Study.

Effectiveness of craniocervical flexion training combined with cervical traction among patients with cervical spondylotic radiculopathy / 预防医学

Objective@# To evaluate the effectiveness of craniocervical flexion training using pressure biofeedback combined with cervical traction among patients with cervical spondylotic radiculopathy (CSR).@*Methods@#Sixty patients with CSR receiving treatment in Center of Rehabilitation, Zhejiang Hospital from January 2020 to December 2021 were enrolled and randomly assigned into the control and treatment groups, of 30 patients in each group. All patients were given cervical traction, and patients in the treatment group were given additional craniocervical flexion training using pressure biofeedback for successive four weeks. The effectiveness of craniocervical flexion training combined with cervical traction was evaluated using Visual Analogue Scale (VAS), Neck Disability Index (NDI) and the active range of motion (AROM) of cervical flexion, and the neck pain and cervical functions were compared between the two groups before and after treatments using repeated-measures analysis of variance.@* Results@# Fifteen men were included in the treatment group, with a mean age of (49.47±5.33) years, mean disease course of (5.53±2.89) months, and mean VAS score of (4.73±1.39) points, and there were no significant differences between the control and treatment groups in terms of gender, age, course of disease or VAS score (P>0.05). The VAS score and NDI were lower 4 weeks post-treatment than pretreatment in both the treatment [VAS score: (2.13±1.01) vs. (4.73±1.39); NDI: (12.17±2.12) vs. (20.20±3.78)] and control groups [VAS score: (2.93±1.11) vs. (4.90±1.21); NDI: (15.23±2.39) vs. (19.60±3.30)], and the AROM of cervical flexion was significantly higher 4 weeks post-treatment than pretreatment in both the treatment [(42.87°±2.99°) vs. (37.50°±2.80°)] and control groups [(41.80°±3.61°) vs. (38.07°±2.99°)]; there was an interaction between time and group, and a higher improvement for cervical functions was seen in the treatment group than in the control group (FVAS =5.119, P=0.027; FNDI=15.473, P<0.001; FAROM=11.443, P<0.001). @*Conclusion@#Craniocervical flexion training using pressure biofeedback combined with cervical traction may effectively alleviate the neck pain and increase the AROM among patients with CRS, which is more effective to improve patients' cervical functions than cervical traction alone.

Quality of life in patients of low back pain with radiculopathy: A descriptive analytical study from Punjab

Background: Low back pain with radicular symptoms is one of the most prevalent musculoskeletal disorders and leading cause of disability. Radicular back pain can be defined as a diffuse process affecting more than one underlying nerve root that causes pain and depending on the severity of symptoms may cause loss of sensation and motor function. Quality of life (QOL) is a multidimensional patient-based outcome criterion which can be used to describe the impact of health condition on the patient as well as the effects of the treatment. Low back pain interferes with QOL and work performance. Aim and Objectives: To analyze the QOL in patients of low back pain with radiculopathy. Materials and Methods: This descriptive-analytical study was carried out on 364 low back pain patients and healthy people in Government medical college, Patiala, India, from January 2021 to June 2021. We used SF-36 questionnaire to assess QOL, which allows calculating eight different scores (on a scale of 0–100), a physical component scale (PCS), and a mental component scale (MCS) summary. Mean Mental (MCS) and Physical (PCS) component summary scores were assessed and compared with healthy people involved in the study. Overall, a higher PCS and MCS score indicates better QOL. Results: Out of 364 patients enrolled, 311 patients with mean age of 49.1 ± 11.9 years were included for the study. SF-36 was administered and assessed. The result from this questionnaire showed that mean PCS and mean MCS were significantly lower in the low back pain patients compared to the normative population and were statistically significant. Conclusion: Patients of low back pain with radiculopathy have poor QOL compared to normative individuals. Lower QOL in patients necessitates getting early treatment, educating the patient, and rehabilitation. It is vital to give more attention to the QOL of the patient as it is an untouched domain.

Regresión espontánea de la hernia discal lumbar de dos féminas / Spontaneous regression of the lumbar herniated disk in two women

Se describen los casos clínicos de dos féminas que habían padecido lumbociatalgias durante varios meses, por lo cual acudieron al Hospital Provincial Docente Dr. Joaquín Castillo Duany de Santiago de Cuba, donde se les diagnosticó hernia discal lumbar y recibieron seguimiento médico en la consulta de Neurocirugía por más de un año. Ante la negativa de ser intervenidas quirúrgicamente, se prescribieron esquemas terapéuticos convencionales y alternativos, así como fisioterapia. En ambas pacientes se evidenció regresión espontánea de la discopatía, lo que se confirmó mediante estudios evolutivos de resonancia magnética. Dicha correlación entre la mejoría clínica y la recuperación imagenológica del disco intervertebral no siempre sucede en la evolución de estos casos.

The case reports of two women that had suffered from lumbar sciatic pain during several months are described, reason why they went to Dr. Joaquín Castillo Duany Teaching Provincial Hospital in Santiago de Cuba, where they were diagnosed lumbar herniated disk and received medical follow up in the Neurosurgery Service for more than a year. Before the negative of being surgically intervened, conservative and alternative therapeutic outlines were prescribed, as well as physiotherapy. In both patients spontaneous regression of the lumbar herniated disk was evidenced, which was confirmed by means of evolutionary studies of magnetic resonance. This correlation between the clinical improvement and the imaging recovery of the intervertebral disk doesn't always happen in the clinical course of these cases.

Comparative study of soleus H-reflex in normal humans and in patients with neuropathies

Background: The H-reflex derived its name from Hoffman. Hoffmann reflex is an electrically induced reflex analogous to the mechanically induced spinal stretch reflex. This measurement can be used to assess the response of the nervous system to various neurological conditions, musculoskeletal injuries, and application of therapeutic modalities, pain, exercise training, and performance of motor tasks. This simple and reproducible physiological response was studied to evaluate conduction along the course of the whole “final common pathway” from the moto neuron to the terminal axon as well as to gain some information regarding the function of large diameter group la afferent fibers supplying the muscle spindle. Aims and Objectives: The aim of the study was to compare the H-reflex latency between the normal person and in neuropathic patients. The study aimed to see whether there is any difference in H-reflex latency in the right leg of normal person and in neuropathic patients. The study aimed to see whether there is any difference in H-reflex latency in the left leg of normal person and in neuropathic patients. Materials and Methods: The study was conducted among 25 normal subjects and 25 neuropathic patients between 20 and 70 years of age from Nootan Medical College and Research Centre, Visnagar. The normal subjects were evaluated clinically to find their normal condition. The neuropathic patients which are included in study are of diabetic neuropathy, plexopathy, radiculopathy, vitamin deficiency, and Guillain Barre Syndrome. The patients who had bilateral neuropathy were included in the study. The study was conducted using mainly stimulator circuit, stimulating and recording electrodes, preamplifier, and oscilloscope. The software used for this experiment was RMS EMG EPMK II, one of the latest software with facilities for nerve conduction velocity, electromyography, F-wave, and H-reflex recording. Results: Out of the 50 participants, 25 participants who were suffering with any kind of neuropathy evaluated for their H-reflex latency in both leg. Patients with neuropathy showed higher latency in the right leg compared to the 25 participants in the control group in the right leg demonstrated significantly higher latency in the group with neuropathy. The 25 participants who were suffering with any kind of neuropathy evaluated for their H-reflex latency left leg compared to the 25 participants in the control group left leg demonstrated significantly higher latency in the group with neuropathy. Conclusion: The results show that there is an increase in the H-reflex latency in neuropathy patients as compared to normal subjects but it can be not used as a specific test for diagnosis of neuropathies, because the H-reflex latency may also change in normal subjects as the age of the persons is increases or the height of the persons increases but H-reflex latency can be used for the diagnosis of the proximal nerve root injuries as it mainly investigates the proximal nerve reflex arc.

Mielopatía cervical degenerativa: una patología cada vez más frecuente y que requiere diagnóstico y manejo precoz

Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in adults. Its prevalence is increasing as a result of population aging. The diagnosis of DCM is often delayed or overlooked, resulting in secondary neurologic morbidity. The natural course of DCM typically presents as a gradual neurological deterioration, with symptoms ranging from muscle weakness to complete paralysis, with variable degrees of sensory deficits and sphincter dysfunction. Magnetic resonance imaging (MRI) and electrophysiological studies allow the assessment of spinal cord function and its structural damage to determine treatment and clinical outcomes. All patients with signs and symptoms consistent with DCM should be referred to a spine surgeon for assessment and tailored treatment. Those patients with mild DCM can be managed non-operatively but require close monitoring and education about potentially alarming signs and symptoms. Surgery is not currently recommended for asymptomatic patients with evidence of spinal cord compression or cervical spinal stenosis on MRI, but they require a structured follow-up. Patients with moderate or severe DCM require surgical decompression to avoid further progression. The objective of this review is to raise awareness of degenerative cervical myelopathy and its increasing prevalence as well as to aid non-surgical healthcare workers for a timely diagnosis and management of this disabling condition.

Radiculopatía asociada a tumor intrarraquídeo extradural en adolescente / Adolescent radiculopathy associated with extradural intraspinal tumor

Resumen: Introducción: Los procesos expansivos intrarraquídeos suelen tener una evolución insidiosa que dificultan su diagnóstico precoz. Los tumores intrarraquídeos son clasificados de acuerdo con su localización en el conducto raquídeo: extradural e intradural, y éstos se clasifican en extramedular e intramedular. Al comienzo, pueden provocar cuadros de dolor poco específicos y, a veces, dolores de tipo radicular. El paciente podrá tener síntomas como: pérdida de fuerza, pérdida de equilibrio, pérdida de sensibilidad y disturbios esfinterianos. Las neoplasias intrarraquídeas, cuando son diagnosticadas, tienen indicación de tratamiento quirúrgico. Material y métodos: Se describe el caso clínico de adolescente masculino de 14 años, dolor en región lumbar desde hace cuatro años, de inicio insidioso, intermitente, progresivo, que se exacerba hace seis meses, con irradiación a extremidades inferiores, que se acompaña de parestesias y paresias progresivas de predominio en extremidad inferior derecha. Resultados: Se realiza laminotomía L4 y L5 bilateral, exploración y resección de tumoración y liberación de raíces nerviosas. Se obtiene tumor de características similares a tejido adiposo en donde se observa amplia red vascular en su interior, con tamaño aproximado de 14 × 10 × 4 mm de forma ovoide, aplanada con superficie lisa y brillante. Conclusión: Los tumores raquimedulares son tumores relativamente raros; sin embargo, de estos tumores, la localización intrarraquídea extradural corresponde a la mitad de los casos. En nuestro paciente, se integró el diagnóstico de lipoma del filum terminale, el cual corresponde a menos de 1% de todos los tumores de la columna vertebral.

Abstract: Introduction: Expansive intra-spinal processes usually have an insidious course that makes their early diagnosis difficult. Intra-spinal tumors are classified according to their location in the spinal canal: extradural and intradural, and these are classified as extramedullary and intramedullary. At the beginning, they can cause non-specific pain conditions and, sometimes, root-type pain. The patient may have symptoms such as: loss of strength, loss of balance, loss of sensation, sphincter disorders. Intra-spinal neoplasms, when diagnosed, have an indication for surgical treatment. Material and methods: The clinical case of a 14-year-old male adolescent is described, pain in the lumbar region for four years, of insidious onset, intermittent, progressive, exacerbated six months ago, with radiation to the lower extremities, which is accompanied by progressive paresthesia and paresis predominantly in the lower right limb. Results: Bilateral L4 and L5 laminotomy is performed, exploration and resection of the tumor and release of nerve roots. Tumor with characteristics similar to adipose tissue is obtained, where a wide vascular network is observed inside, with an approximate size of 14 × 10 × 4 mm, ovoid in shape, flattened with a smooth and shiny surface. Conclusion: Spinal tumors are relatively rare tumors, however, of these tumors, the extradural intraspinal location accounts for half of the cases. In our patient, the diagnosis of lipoma of the filum terminale was integrated, which corresponds to less than 1% of all tumors of the spine.

Effects of Fixed-Point Lateral Flexion and Rotation Manipulation on Intervertebral Foramina Morphology of Cervical Spondylotic Radiculopathy / 医用生物力学

Objective To analyze the changes in morphology of intervertebral foramina in patients with cervical spondylotic radiculopathy (CSR) treated with fixedpoint lateral flexion and rotation manipulation based on three-dimensional (3D) reconstruction technology, so as to provide references for the effectiveness of manipulation treatment. MethodsForty patients with CSR were treated with fixed point lateral flexion and rotation manipulation once every other day for a total of 7 times and 2 weeks as a course of treatment. CT data of the patients before and after treatment were analyzed by using multifunctional CT, Mimics 21.0, Geomagic and SolidWorks 2017. The area of the intervertebral foramen, anterior and posterior diameter of the intervertebral foramen, upper and lower diameter of the intervertebral foramen were measured before and after treatment, as well as the infrared thermal imaging temperature differences of the bilateral neck and shoulder, front and back of the upper limb, and the VAS scores of the patients were observed before treatment, 7 d after treatment, 14 d after treatment and 1 month follow-up. Results Foraminal area, anterior and posterior diameters, upper and lower diameters of 40 patients were improved after treatment, and the temperature differences of infrared thermal imaging of patients before and after treatment were statistically significant. The VAS score of the patients decreased progressively. Conclusions Fixed point lateral flexion manipulation can significantly improve the shape of the intervertebral foramen in patients with CSR, so as to achieve the treatment purpose of relieving nerve compression.

Analgesic Effects of Two Types of Spinal Manipulation in Acute Lumbar Radiculopathy Model Rats / 中国结合医学杂志

OBJECTIVE@#To compare the analgesic effects of two types of spinal manipulation (SM) in acute lumbar radiculopathy (ALR) model rats induced by self-transplantation of autologous nucleus pulposus (ANP), and clarify the therapeutic mechanism.@*METHODS@#Totally 108 male Sprague-Dawley rats were randomly divided into 6 groups by a random number table (18 rats in each group), including a blank group with no interference, a sham operation group with a surgery by making a local soft tissue incision on the left side of L5-6 vertebral segment, a model group with ALR of L5 extraforaminal nerve by ANP self-transplantation without other interference, a sham manipulation (SMA) group with simulating physical rotation, as well as a mobilization (MOB) group with simulating low-velocity and variable-amplitude rotation and a manipulation (MAN) group with simulating high-velocity and low-amplitude rotation. The interventions in SMA, MOB, and MAN groups started 1 day after modeling followed by another 5 treatments at days 3, 5, 8, 10 and 12. Rats in the other 3 groups did not receive any special intervention. Behavioral pain tests of 50% mechanical pain withdrawal threshold (50% PWT) and paw withdrawal latency (PWL) were conducted 1 day before operation followed by another 10 tests on days 1-7, 10, 12 and 14. Immunohistochemical expression of nitric oxide synthase (NOS) was investigated on days 5 and 12 after operation.@*RESULTS@#After 3 experimental SM interventions, 50% PWT and PWL were higher in the MAN group than the SMA group on days 6 and 7, and higher on days 10, 12 and 14 postoperatively (P<0.05 or P<0.01), while the same indices were significantly higher in the MOB group than MAN group on days 1-4 (P<0.05 or P<0.01). The expression of NOS was lower in the MAN and MOB groups than SMA group on day 12 postoperatively (P<0.01).@*CONCLUSIONS@#Both manipulation and mobilization produced better results than sham interference in relieving pain by reducing neuroinflammation possibly. At the early period, compared with manipulation, mobilization presented less sensitive response to pain until later visit. SM may inhibit the overexpression of NOS, thereby alleviating severe radiculopathy.

Effect of wheat-grain moxibustion on the expression of Beclin-1/GRP78 in spinal dorsal horn in rats with cervical spondylotic radiculopathy / 中国针灸

OBJECTIVE@#To observe the effect of wheat-grain moxibustion at "Dazhui" (GV 14) on the expressions of Beclin-1 and GRP78 in spinal dorsal horn in rats with cervical spondylotic radiculopathy (CSR), and to explore the possible analgesic mechanism of wheat-grain moxibustion for CSR.@*METHODS@#A total of 48 SD rats were randomly divided into a sham operation group, a model group, a wheat-grain moxibustion group and a wheat-grain moxibustion+3-MA group, 12 rats in each group. The CSR model was prepared by spinal cord insertion method. Three days after modeling, the rats in the model group were intraperitoneally injected with 1 mL of 0.9% sodium chloride solution; the rats in the wheat-grain moxibustion group were treated with wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time) on the basis of the model group; the rats in the wheat-grain moxibustion+3-MA group were intraperitoneally injected with 3-MA solution and wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time). The three groups were intervened for 7 days, once a day. The gait score and mechanical pain threshold were observed before treatment and 7 days into treatment; after the treatment, the expressions of mRNA and protein of Beclin-1 in spinal dorsal horn were detected by real-time fluorescence quantitative PCR and immunohistochemistry; the expression of GRP78 protein in spinal dorsal horn was detected by Western blot method; the autophagosomes and ultrastructure in spinal dorsal horn neurons were observed by electron microscope.@*RESULTS@#After the treatment, compared with the sham operation group, in the model group, the gait score was increased and the mechanical pain threshold was decreased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was increased (P<0.01). Compared with the model group and the wheat-grain moxibustion+3-MA group, in the wheat-grain moxibustion group, the gait score was decreased and mechanical pain threshold was increased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was decreased, and the expressions of mRNA and protein of Beclin-1 were increased (P<0.01). Under electron microscope, the ultrastructure of spinal dorsal horn neurons in the wheat-grain moxibustion group was not significantly damaged, and its structure was basically close to normal, and the number of autophagosomes was more than the other three groups.@*CONCLUSION@#Wheat-grain moxibustion at "Dazhui" (GV 14) has analgesic effect on CSR rats. The mechanism may be related to moderately up-regulate the expression of Beclin-1, enhance autophagy and reduce endoplasmic reticulum stress.

Clinical trial of Guige Shujing Decoction combined with acupuncture in the treatment of cervical spondylotic radiculopathy with coldness-blood stasis obstructing meridians / 国际中医中药杂志

Objective:To explore the clinical effect of Guige Shujing Decoction combined with acupuncture in the treatment of cervical spondylotic radiculopathy with coldness-blood stasis obstructing meridians.Methods:A total of 86 patients with coldness-blood stasis obstructing meridians of cervical spondylotic radiculopathy, who met the inclusion criteria from May 2019 to May 2021, were divided into two groups, with 43 cases in each group, according to the random number table method. The control group was treated with routine basic treatment and acupuncture, and the observation group was treated with routine basic treatment, acupuncture and Guige Shujing Decoction. Both groups were treated for 4 weeks and followed up for 6 months. The scores of TCM syndromes were performed before and after treatment, Clinical Assessment Scale for Cervical Spondylosis (CASCS) was used to evaluate cervical spine function, Visual Analogue Score (VAS) was used to evaluate the degree of pain, Neck Disability Index (NDI) was used to evaluate cervical spine function, and ELISA was used to detect levels of hypersensitive C-reactive protein (hs-CRP), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α). The adverse reactions were observed during treatment and the recurrence rate was recorded during follow-up.Results:The total effective rate of the observation group was 95.35% (41/43), and that of the control group was 81.40% (35/43), the difference between the two groups was statistically significant ( χ2=4.07, P=0.043). After treatment, the scores and total scores of shoulder and neck pain, upper limb numbness, neck stiffness, head tenderness and heaviness in the observation group were significantly lower than those in the control group ( t values were 10.66, 12.89, 9.12, 12.27 and 8.75, respectively, P<0.001). After treatment, the CASCS score in the observation group was significantly higher than that of the control group ( t=2.64, P=0.010). After treatment, the VAS and NDI scores in the observation group were significantly lower than those in the control group ( t values were 5.62 and 7.00, respectively, P<0.001). After treatment, the levels of serum hs-CRP, IL-1β and TNF-α in the observation group were significantly lower than those in the control group ( t values were 6.65, 7.52 and 5.08, respectively, P<0.001). There was no significant difference in the incidence of adverse reactions between the two groups during treatment ( χ2=0.73, P=0.393). After 6 months of follow-up, the recurrence rate in the observation group was 2.44% (1/41) and that in the control group was 17.14% (6/35). There was a statistically significant difference in the recurrence rate between the two groups ( χ2=3.89, P=0.048). Conclusion:The Guige Shujing Decoction combined with acupuncture therapy can inhibit the neurogenic inflammatory reaction of patients with coldness-blood stasis obstructing meridians of cervical spondylotic radiculopathy, reduce pain, improve cervical spine function, reduce recurrence rate and improve curative effect.

Sensitivity of Laségue Sign and Slump Test in Hernia and Disc Bulging Diagnoses Compared with Magnetic Resonance Imaging / Sensibilidade das manobras de Laségue e de slump nos diagnósticos de hérnia e abaulamento discal em comparação com ressonância magnética

Abstract Objective To show the accuracy of the most used maneuvers in the clinical diagnosis of lumbosciatalgia, the slump test and the Laségue sign. Methods In order to perform the present study, 101 patients with magnetic resonance imaging (MRI) discopathy (gold standard) were selected and had their medical records reviewed to identify which had the positive maneuvers on the initial physical examination. Results The sensitivity found for the slump test and the Laségue sign in the diagnosis of disc herniation was 55.3% and 18.1%, respectively. Nonetheless, when they were compared with each other for the diagnosis of disc bulging, the sensitivity obtained was of 85.7% for the slump test and of 28.6% for the Laségue sign. Conclusion Comparing both clinical exams with MRI, it was found that the slump test presents superior sensitivity compared with the Laségue sign for both the diagnosis of hernia and disc bulging, and should be more present in clinical practice.

Neurophysiological assessment of brachioradial pruritus patients / Avaliação neurofisiológica de pacientes com prurido braquiorradial

Abstract Background: Pruritus is a common complaint in dermatology. Wartenberg, in 1943, associated pruritus with neuropathy, relating it to the "posterior antebrachial cutaneous nerve neuropathy". In 1968, Waisman described patients with frequent pruritus complaints in the upper limb during the summer, which he named "brachioradial summer pruritus". Currently, this pruritus is named brachioradial pruritus (BRP). BRP is characterized by a chronic pruritus, usually localized, with a long duration, and without apparent cutaneous abnormalities. Neurological disorders both from the central and peripheral nervous systems, including multiple sclerosis, are associated with pruritus. Objective: To investigate correlations between symptomatic dermatomes and alterations in the myotomes, as evidenced by electroneuromyography (ENMG). Methods: Forty-six patients with BRP dermatological diagnoses were subjected to upper limb ENMG. Results: Among 46 patients with C5 to C8 dermatomal pruritus, we evaluated 113 symptomatic dermatomal areas. Overall, 39 (85%) patients had radicular involvement and 28 (60%) had agreement between complaint and the ENMG findings (p=0.015). A total of 80% of the patients with complaints at C7 and 47% at C6 had radicular involvement at the same level. Conclusions: Among the patients who presented complaints, 47 and 80%, respectively, had ENMG alterations in the C6 and C7 myotomes. We conclude that peripheral nervous system involvement is associated with BRP.

RESUMO Antecedentes: O prurido constitui queixa frequente e desafiadora na prática dermatológica. O primeiro estudo a relacionar prurido com neuropatia foi de Wartenberg, em 1943, que associou à "neuropatia do nervo cutâneo antebraquial posterior". Em 1968, Waisman descreveu pacientes com queixas recorrentes de prurido em membros superiores no verão, sendo denominado, então, "brachioradial summer pruritus". Atualmente, esse prurido é denominado como prurido braquiorradial (PBR). O PBR é caracterizado por prurido crônico, geralmente bem localizado, de longa duração e sem anormalidades cutâneas aparentes. Doenças neurológicas, tanto centrais, esclerose múltipla ou acidente vascular cerebral como do sistema nervoso periférico, estão associadas a prurido. Objetivo: Investigar os dermátomos sintomáticos pela eletroneuromiografia (ENMG). Métodos: Foram estudados 46 pacientes com diagnóstico dermatológico de PBR com a eletroneuromiografia dos membros superiores. Resultado: Foram avaliados 46 pacientes com queixa dermatológica de C5 a C8 somando 113 áreas dermatoméricas sintomáticas. Observou-se que 39 (85%) pacientes apresentavam comprometimento radicular, sendo que em 28 (60%) houve concordância plena entre as queixas e os achados da ENMG (p=0,015), e que 80% dos pacientes com queixa em território de C7 e 47% em C6 apresentavam comprometimento radicular no mesmo nível. Conclusões: As queixas mais frequentes foram as correspondentes aos territórios de C6 e C7, sendo que 47 e 80%, respectivamente, apresentaram alteração na ENMG nesses miótomos. Dessa forma, evidenciou-se correlação entre comprometimento do sistema nervoso periférico (i.e., radicular) com PBR.

Dorsal Root Entry Zone Lesioning: Systematic Review

Introduction Dorsal root entry zone (DREZ) leasioning (DREZ-otomy) is considered an effective treatment for chronic pain due to spinal cord injuries, brachial and lumbosacral plexus injuries, postherpetic neuralgia, spasticity, and other conditions. The objective of the technique is to cause a selective destruction of the afferent pain fibers located in the dorsal region of the spinal cord. Objective To identify and review the effectiveness and the main aspects related to DREZ-otomy, as well as the etiologies that can be treated with it. Methods The PubMed, MEDLINE and LILACS databases were used as bases for this systematic review, having the impact factor as the selection criteria. The 23 selected publications, totalizing 1,099 patients, were organized in a table for systematic analysis. Results Satisfactory pain control was observed in 70.1% of the cases, with the best results being found in patients with brachial/lumbosacral plexus injury (70.8%) and the worst, in patients with trigeminal pain (40% to 67%). Discussion Most of the published articles observed excellent results in the control of chronic pain, especially in cases of plexus injuries. Complications are rare, and can be minimized with the use of new technologies for intraoperative monitoring and imaging. Conclusion DREZ-otomy can be considered a great alternative for the treatment of chronic pain, especially in patients who do not tolerate the side effects of the medications used in the clinical management or have refractory pain.

Therapeutic efficacy observation of warm needling moxibustion plus spine subtle adjusting manipulation for cervical radiculopathy / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of warm needling moxibustion plus spine subtle adjusting manipulation for cervical radiculopathy. Methods: A total of 70 patients with cervical radiculopathy were randomized into an observation group and a control group, with 35 cases in each group. The observation group was treated with warm needling moxibustion plus spine subtle adjusting manipulation, while the control group was treated with warm needling moxibustion alone. The treatments were performed three times a week, and for four weeks in total. The visual analog scale (VAS) was scored before and after treatment. And the clinical efficacy of the two groups was compared after treatment. Results: The total effective rate was 97.1％ in the observation group, versus 88.6％ in the control group. The difference between the two groups was statistically significant (P<0.05). After treatment, the VAS scores in both groups significantly decreased (P<0.01), and the score in the observation group was significantly lower than that in the control group (P<0.05). Conclusion: Warm needling moxibustion plus spine subtle adjusting manipulation has a better effect in the treatment of cervical radiculopathy than warm needling moxibustion alone.
