Effectiveness of respiratory proprioceptive neuromuscular facilitation technique on pulmonary function in spinal cord injury patients: a randomized controlled trial

Background: Spinal cord injury (SCI) often leads to respiratory complications due to impaired neuromuscular control. Proprioceptive neuromuscular facilitation (PNF) techniques have shown promise in improving respiratory function in various populations, but their effectiveness in SCI patients remains underexplored. This study aimed to investigate the effectiveness of respiratory PNF techniques on pulmonary function in individuals with SCI. Methods: A randomized controlled trial was conducted involving SCI patients with respiratory impairment. A total of 43 participants were included in this study. The study duration was 4 years with an intervention period of 4 weeks and the outcome measures were pulmonary functions and chest expansion using inch tape. Results: There was a significant improvement in pulmonary functions in the control group and a highly significant improvement in pulmonary functions in the experimental group after 4 weeks of interventions and chest expansion was significantly improved in the experimental group. Conclusions: The respiratory PNF techniques demonstrated a clinically meaningful enhancement in pulmonary function and chest mobility among SCI patients. Respiratory PNF techniques represent a valuable adjunct therapy for improving pulmonary function and chest mobility in individuals with SCI.

Unexpected clinical and functional recovery in patients with chronic traumatic chronic spinal cord injury: a case series

Motor recovery in traumatic spinal cord injury (tSCI) is reported to reach its plateau by 1 year and maximum recovery period is reported to be 2 years. Acute rehabilitation is very well documented in literature with patients reporting for functional rehabilitation immediately after shock period is over. However, the scenario being a bit different in rural areas with comparatively less awareness about role of physiotherapy, patients with tSCI reports at later stages. Reported here is a series of chronic tSCI cases who showed remarkable clinical and functional recovery in short time. Aim of this study is to report recovery in patients with chronic tSCI and to compare the patient outcomes with expected outcomes. Conventional physiotherapy was given 5 days a week with minimum 45 mins treatment. Baseline assessment at admission and at discharge was recoded. Improvement was recorded with spinal cord independence at different time points. Nine patients below 40 years of age, average duration of injury 6.2 years were treated for average of 8 months. NLI did not change in 3 patients whereas in 6 patients NLI moved 2 segments down. Mean change in SCIM score was 10 between admission and discharge. Functional status was compared with expected parameters and was found to be improved by 70%, suggesting had they come at early stage, expected recovery could have been achieved. Clinical and functional recovery in patients with tSCI may occur even after 2 years post injury.

Influences of Glabridin Treatment on Motor Function Recovery after Spinal Cord Injury / Influencia del Tratamiento con Glabridina en la Recuperación de la Función Motora después de una Lesión de la Médula Espinal

SUMMARY: Spinal cord injury (SCI) usually arises from compression due to traffic accidents and falls, resulting in varying degrees of movement, sensory loss, and possible paralysis. Glabridin (Gla) is a natural compound derived from licorice. It significantly affects drug development and medicine because of its anti-inflammatory, anti-oxidative, anti-tumoral, antibacterial, bone protective, cardiovascular protective, neuroprotective, liver protective, anti-obesity, and anti-diabetic properties. Various methods were employed to administer Gla to SCI mice in order to investigate its impact on the recovery of motor function. The mice were allocated into four cohorts using a randomization procedure. In the sham cohort, solely the lamina of vertebral arch was surgically exposed without causing any harm to the spinal cord tissue. Conversely, the injury cohort was subjected to spinal cord tissue damage and received no treatment thereafter. The mice in the remaining two cohorts received a dosage of 40 mg/kg Gla every two days via either intraperitoneal or intrathecal injection for a duration of 42 d following spinal cord injury. We conducted behavioral tests utilizing the Basso Mouse Scale score and gait analysis techniques. Magnetic resonance imaging and hematoxylin and eosin were employed to evaluate scar tissue formation. Systemic inflammation in mice was evaluated by employing an enzyme-linked immunosorbent assay. Gla promoted motor function recovery in mice following SCI and improved the pathological environment in the damaged area. These alterations were more evident in mice subjected to the intrathecal injection method. Intraperitoneal injections appear to be more beneficial for controlling systemic inflammatory responses. Although more intensive studies are required, Gla exhibits promising clinical potential as a cost-effective dietary phytochemical.

La lesión de la médula espinal (LME) generalmente surge de la compresión producto de caídas y accidentes de tránsito, lo que resulta en alteraciones del movimiento, pérdida sensorial y posible parálisis. La Glabridina (Gla) es un compuesto natural derivado del regaliz, constituyéndose en un aporte significativo para el desarrollo de fármacos y la medicina debido a sus propiedades antiinflamatorias, antioxidantes, antitumorales, antibacterianas, osteoprotectoras, cardioprotectoras, neuroprotectoras, hepatoprotectoras, antidiabéticas y contra la obesidad. En el presente trabajo se emplearon varios métodos para administrar Gla a ratones con lesión medular con el fin de investigar su impacto en la recuperación de la función motora. Los ratones fueron distribuidos en cuatro grupos mediante un procedimiento de aleatorización. En el grupo simulado, únicamente se expuso quirúrgicamente la lámina del arco vertebral sin causar ningún daño al tejido de la médula espinal. Por el contrario, el grupo lesionado fue sometido a daño del tejido de la médula espinal, sin recibir tratamiento posterior. Los ratones de los dos grupos restantes recibieron una dosis de 40 mg/kg de Gla cada dos días mediante inyección intraperitoneal o intratecal durante 42 días después de la lesión de la médula espinal. Fueron realizadas pruebas de comportamiento utilizando la puntuación de la escala Basso Mouse y técnicas de análisis de la marcha. Se emplearon imágenes por resonancia magnética y se aplicaron tinciones histológicas (Hematoxilina & Eosina) en muestras para evaluar la formación de tejido cicatricial. La inflamación sistémica en ratones se evaluó mediante el empleo de un ensayo inmunoabsorbente ligado a enzimas. Gla promovió la recuperación de la función motora en ratones después de una lesión medular y mejoró el entorno patológico en el área dañada. Estas alteraciones fueron más evidentes en ratones sometidos al método de inyección intratecal. Las inyecciones intraperitoneales parecen ser más beneficiosas para controlar las respuestas inflamatorias sistémicas. Aunque se requieren estudios más intensivos, Gla exhibe un potencial clínico prometedor como fitoquímico dietético rentable.

COVID-19 associated transverse myelitis: case report / Mielitis transversa asociada a COVID-19: reporte de un caso

Abstract Background: Transverse myelitis (TM) is a demyelinating inflammatory disease that presents with motor, sensory, and autonomic dysfunction, which may be acute or subacute. COVID-19-associated TM has been described in a scarce number of patients. Clinical case: A 15-year-old previously healthy male patient with respiratory disease before his neurological deterioration presented to the emergency room after developing a complete medullary syndrome located at the cervical-dorsal level, with ascending and symmetric paraparesis that rapidly progressed to paraplegia, with sensory dysfunction from the T3 level, sphincter dysfunction and sudden ventilatory deterioration that required mechanical ventilation. Magnetic resonance imaging was compatible with acute TM. Inflammatory and non-inflammatory etiologies were discarded. In addition, a positive severe acute respiratory syndrome coronavirus 2 test was obtained. Treatment included steroid pulses and plasmapheresis, with an insidious evolution. Conclusion: COVID-19 is an infrequent cause of TM and should be suspected when other etiologies have been ruled out.

Impact of COVID-19 on socio-behavioural, health and oral health-related aspects on spinal cord injury patients: a cross-sectional study

Background: Spinal cord injury (SCI) is a damaging, life-altering injury, which is estimated to have an annual global incidence of 40 to 80 cases per million population and is two to five times more possible to die prematurely. This study aims to evaluate the impact of COVID-19 on socio-behavioural, health, and oral health-related aspects of spinal cord injury patients. Methods: This cross-sectional study was conducted among 50 spinal cord injury patients in the rehabilitation center in Chennai, Tamil Nadu, which was conducted between May and June 2022. Results: The comparison of mean distribution scores based on DMFT showed that complete injury patients had a lower DMFT score of 6.40 when compared to incomplete injury (8.41). The periodontal status assessment revealed that SCI with complete injury had a lower mean number of teeth with gingival bleeding and periodontal pocket (3.81 and 2.31 respectively) when compared to incomplete injury (7.12 and 4.49). Moreover, the impact of COVID-19 on the socio-behavior and health status was found to be higher in complete injury than that in incomplete injury patients. Conclusions: Therefore, this pandemic highlights the need to advocate the development of a nationwide SCI registry or surveillance system is fundamental to an understanding of the epidemiology and, hence, the prevention of this emerging health burden.

Spinal cord electrical stimulation with neurophysiological monitoring for treatment of high-risk diabetic foot / 中华危重病急救医学

Objective:To evaluate the clinical efficacy of a single-session implantation of spinal cord electrical stimulation with neurophysiological monitoring a spinal cord electrical stimulator under general anesthesia with neurophysiological monitoring for the treatment of high-risk diabetic foot.Methods:The clinical data of seven patients with high-risk diabetic foot who underwent spinal cord electrical stimulation in neurosurgery ward nine of Tianjin Huanhu Hospital from May 2022 to May 2023 were collected. The operation was performed under general anesthesia with the "C" arm X ray machine guidance and neurophysiological monitoring. The arterial diameter and peak flow rate of lower extremity, lower extremity skin temperature (calf skin temperature, foot skin temperature), visual analog scale (VAS), continuous distance of movement, blood glucose level and toe wound were compared between patients before and after surgery.Results:A total of seven patients with high-risk diabetic foot were included. The diameters and peak flow rates of femoral artery, popliteal artery, anterior tibial artery, posterior tibial artery and dorsal foot artery in both lower limbs were significantly improved after surgery. All patients had different degrees of lower limb pain before operation. After operation, VAS score decreased significantly (1.1±0.9 vs. 6.8±3.4), the pain was significantly relieved, and the calf skin temperature and foot skin temperature were significantly higher than those before surgery [calf skin temperature (℃): 33.3±0.9 vs. 30.9±0.7, foot skin temperature (℃): 31.4±0.8 vs. 29.1±0.6], fasting blood glucose and postprandial blood glucose were significantly lower than those before surgery [fasting blood glucose (mmol/L): 7.6±1.4 vs. 10.5±1.2, postprandial blood glucose (mmol/L): 9.3±2.3 vs. 13.5±1.1], the differences were statistically significant (all P < 0.01). The lower limb movement of all seven patients was significantly improved after surgery, including one patient who needed wheelchair travel before surgery, and one patient who had intermittent claudication before surgery. Among them, one patient needed wheelchair travel and one patient had intermittent claudication before surgery. All patients could walk normally at 2 weeks after operation. Among the seven patients, two patients had the diabetic foot wound ulceration before surgery, which could not heal for a long time. One month after surgery, blood flow around the foot wound recovered and the healing was accelerated. The wound was dry and crusted around the wound, and the wound healed well. Conclusion:For diabetic high-risk foot patients who are intolerant to diabetic peripheral neuralgia and local anesthesia spinal cord electrical stimulation test, one-time implantation of spinal cord electrical stimulator under general anesthesia under neurophysiological monitoring can effectively alleviate peripheral neuralgia and other diabetic foot related symptoms, improve lower limb blood supply, and reduce the risk of toe amputation. Clinical practice has proved the effectiveness of this technique, especially for the early treatment of diabetic high-risk foot patients.

Application effect of discharge preparation service based on theory of goal attainment on patients with cervical spinal cord injury / 中华创伤杂志

Objective:To investigate the application effect of discharge preparation service based on theory of goal attainment on patients with cervical spinal cord injury.Methods:A retrospective cohort study was conducted to analyze the clinic data of 60 patients with cervical spinal cord injury admitted to Zhengzhou Orthopedics Hospital from January 2017 to December 2022, including 49 males and 11 females, aged 23-79 years [(52.2±13.5)years]. Patients were all treated with cervical decompression fusion and internal fixation. Patients admitted from January 2017 to December 2019 were treated with conventional nursing intervention (conventional nursing group, n=30) and patients admitted from January 2020 to December 2022 were treated with discharge preparation service based on theory of goal attainment (discharge preparation service group, n=30). The readiness for hospital discharge of the two groups was compared using the Chinese version of Readiness for Hospital Discharge Scale (RHDS) at 4 hours before discharge. The degree of cervical spinal cord dysfunction of the two groups were compared using Japanese Orthopedic Association (JOA) score before intervention, at discharge and at 6 months after discharge. The complication and unplanned readmission rates of the two groups were compared at 6 months after discharge. Results:All the patients were followed up for 6 months. At 4 hours before discharge, the scores of the three parameters of RHDS containing personal status, adaptability and anticipatory support and the total score of the discharge preparation service group were (20.9±3.5)points, (35.9±2.2)points, (30.4±3.0)points and (87.1±7.8)points respectively, higher than those of the conventional nursing group [(16.2±1.7)points, (32.5±2.2)points, (26.3±2.1)points and (75.0±5.6)points respectively] ( P<0.01). There was no statistically significant difference in the JOA score of the two groups before intervention ( P>0.05). The JOA scores of the discharge preparation service group at discharge and at 6 months after discharge were (11.8±1.7)points and (13.8±1.5)points respectively, higher than those of the conventional nursing group [(10.3±1.8)points and (11.6±1.9)points respectively] ( P<0.01). At 6 months after discharge, the complication rate of the discharge preparation service group was 6.7% (2/30), lower than that of the conventional nursing group [36.7% (11/30)] ( P<0.05). The unplanned readmission rate of the discharge preparation service group was 3.3% (1/30), lower than that of the conventional nursing group [23.3% (7/30)] ( P<0.05). Conclusion:For patients with cervical spinal cord injury, discharge preparation service based on theory of goal attainment can improve the discharge readiness, promote spinal functional recovery and reduce the complication and unplanned readmission rates.

Hidden neuraxial pathology in idiopathic scoliosis: original research / Patologia neuroaxial oculta na escoliose idiopática: pesquisa original / Patología neuroaxial oculta en la escoliosis idiopática: investigación original

ABSTRACT Objective: To evaluate the prevalence of hidden neuraxial pathology (NAP) revealed in idiopathic scoliosis (IS) in neurologically normal patients. Methods: We selected 401 patients with IS who visited our clinic. We identified patterns of NAP and its frequency. In addition to the main part of the study, we assessed the reliability of Magnetic Resonance Imaging (MRI) measuring of the pedicles to plan screw width and trajectory. Results: Among the 401 patients, 53 (13%) presented NAP. The proportion of males in this group was higher (42% vs. 21%, p=0.004), the age of onset of the deformity was lower (8.9±3.77 vs. 9.9±3.93 years old, p=0.045), the left-sided thoracic curve was more frequent (21% vs. 8%, p=0.016), thoracic kyphosis was more pronounced (p=0.070), and the percentage of revision surgeries for deformity progression or non-fusion was higher (13% vs. 5%, p=0.147). Conclusions: The spine MRI should be performed in the early stages of IS, as in some cases of NAP (Chiari, tethered spinal cord), there is the possibility of an early neurosurgical operation that will prevent the development of scoliosis. The main signs of hidden NAP in IS are early-onset IS, IS with left-sided thoracic curve, male gender, and thoracic kyphosis > 40°Cobb. Level of Evidence II; Retrospective Study.

Resumo: Objetivo: Avaliar a prevalência das patologias neuroaxiais ocultas (PNO) reveladas na escoliose idiopática (EI) em pacientes neurologicamente normais. Métodos: Foram selecionados 401 pacientes com EI que visitaram nossa clínica. Identificamos padrões de PNO e sua frequência. Além disso, avaliamos a confiabilidade da medição por ressonância magnética (RM) dos pedículos para planejar a largura e a trajetória do parafuso. Resultados: Entre os 401 pacientes, 53 (13%) apresentaram PNO. A proporção de homens neste grupo foi maior (42% contra 21%, p=0,004), a idade de início da deformidade foi menor (8,9±3,77 contra 9,9±3,93 anos, p=0,045), a curva torácica do lado esquerdo foi mais frequente (21% contra 8%, p=0,016), a cifose torácica foi mais pronunciada (p=0,070) e a porcentagem de cirurgias de revisão para progressão da deformidade ou não fusão foi maior (13% contra 5%, p=0,147). Conclusões: A ressonância magnética da coluna deve ser realizada nos estágios iniciais da EI, pois em alguns casos de PNO (Chiari, medula espinhal amarrada) existe a possibilidade de uma operação neurocirúrgica precoce que impedirá o desenvolvimento de escoliose. Os principais sinais de PNO oculta na EI são: EI de início precoce, EI com curvatura torácica à esquerda, sexo masculino e cifose torácica > 40°Cobb. Nível de Evidência II; Estudo Retrospectivo.

However, it should be considered in patients with a history of associated spinal cord trauma who present early signs of respiratory difficulty, to investigate and offer timely management to this clinical condition. We present the case of a 65-year-old man with chronic diaphragmatic weakness due to a history of gunshot wounds at the level of the cervical spine.

Electrical Stimulation Prevents Muscular Atrophy and the Decrease of Interleukin-6 in Paralyzed Muscles after Spinal Cord Injury in Rats / A estimulação elétrica previne a atrofia muscular e a diminuição da interleucina-6 em músculos paralisados após lesão da medula espinal em ratos

Abstract Objective To analyze the muscle trophism and expression of interleukin-6 in the biceps brachii muscle of rats with incomplete cervical spinal cord injury treated with neuromuscular electrical stimulation (NMES). Methods Adult rats underwent C5-C7 spinal cord hemisection and a 5-week NMES protocol. Trophism of the biceps brachii was assessed using muscle weight/body weight ratio and histological analysis. Interleukin-6 expression from biceps brachii was measured using the enzyme-linked immunosorbent assay technique. Results Preservation of the biceps brachii muscle trophism was found in the NMES treated group, along with prevention of interleukin-6 level reduction. Conclusion Spinal cord injury causes muscle atrophy and decreases interleukin-6 levels. These alterations are partially prevented by NMES. The results suggest a possible NMES action mechanism and underscore the clinical use of this therapeutic tool.

Resumo Objetivo Analisar o trofismo muscular e a de interleucina-6 no músculo bíceps braquial de ratas com lesão medular cervical incompleta tratados com estimulação elétrica neuromuscular (EENM). Métodos Ratas adultas foram submetidas à hemissecção da medula espinal em C5-C7 e a um protocolo de EENM de 5 semanas. O trofismo do bíceps braquial foi avaliado pela relação peso muscular/peso corporal e análise histológica. A expressão de interleucina-6 no bíceps braquial foi medida usando ensaio de imunoabsorção enzimática. Resultados O grupo tratado com EENM apresentou preservação do trofismo muscular, assim como prevenção da redução dos níveis de interleucina-6. Conclusão A lesão da medula espinal causa atrofia muscular e diminui a expressão de interleucina-6. Essas alterações são parcialmente prevenidas pela EENM. Os resultados sugerem um possível mecanismo de ação da EENM e ressaltam o uso clínico desta ferramenta terapêutica.

Compressive Myelopathy Caused by Arachnoid Cyst and Extramedullary Hematopoietic Tissue in a Patient with Thalassemia Major / Mielopatia compressiva por cisto aracnóideo e tecido hematopoiético extramedular em paciente portador de talassemia maior

Thalassemias, inherited diseases of hemoglobin synthesis, are characterized by the presence of deficient hemoglobin chains that deposit in red blood cells, inducing hemolytic anemia. Extramedullary hematopoiesis represents a compensatory picture that usually affects the liver, the spleen, and lymph nodes. The involvement of the epidural space with spinal cord compression is extremely rare. Our objective was to describe the case of RMS, 31 years old, male, ß-thalassemia major carrier, admitted with 2-month progressive paraparesis and urinary retention due to medullary compression by extramedullary hematopoietic tissue and thoracic arachnoid cyst, and to discuss therapeutic options. Magnetic resonance imaging (MRI) showed an extensive intraspinal and extramedullary lesion with homogeneous contrast enhancement of T3- T11 in addition to a T1-T3 cystic lesion isointense to cerebrospinal fluid (CSF). After the presumed diagnosis of spinal cord compression by proliferative hematopoietic tissue, a 10-session fractional radiotherapy treatment was immediately performed. After the radiotherapy treatment, the neurological deficits of the patient persisted despite the excellent image response with almost complete disappearance of the intraspinal mass. However, the MRI showed a persistent T1-T3 cystic lesion with significant mass effect on the spinal cord. The patient was submitted to microsurgery for total resection of this cystic lesion. In the postoperative period, the patient improved his sphincter control and motor deficits. Medullary compression by extramedullary epidural hematopoiesis is a rare complication in thalassemic patients and may be treated with surgery and/or radiotherapy. There are successful cases with the exclusive use of radiotherapy, especially in extensive lesions.

As talassemias, desordens hereditárias da formação de hemoglobina, caracterizam-se pela síntese de cadeias deficientes de hemoglobina que se depositam nas hemácias e induzem a anemia hemolítica. A hematopoiese extramedular representa um quadro compensatório que habitualmente afeta o fígado, o baço e linfonodos, podendo também afetar outros tecidos. O envolvimento do espaço epidural com compressão medular é extremamente raro. No presente trabalho, objetivou-se descrever o caso do paciente RMS, 31 anos, sexo masculino, portador de talassemia ß maior, com paraparesia progressiva há 2 meses e retenção urinária devida à compressão medular por tecido hematopoiético extramedular e cisto aracnóideo torácicos, e discutir as opções terapêuticas. Ressonância magnética (RM) evidenciou extensa lesão expansiva intrarraquiana e extramedular com captação homogênea de contraste de T3-T11, além de lesão cística isointensa ao líquor de T1-T3. Devido à extensão da lesão e anemia grave do paciente, foi optado inicialmente pelo tratamento radioterápico fracionado em 10 sessões. Após o tratamento, o paciente manteve os déficits neurológicos apesar da excelente resposta imaginológica, com desaparecimento quase completo da massa intrarraquiana. Contudo, a RM de controle mostrou persistência da lesão cística T1-T3 com efeito de massa importante sobre a medula. O paciente foi submetido a microcirurgia com ressecção completa da lesão cística. No pós-operatório, houve melhora do controle esfincteriano e dos déficits motores. Compressão medular por hematopoiese extramedular epidural é uma complicação rara nos pacientes talassêmicos, e pode ser tratada com cirurgia e/ou radioterapia. Há casos de sucesso com uso de radioterapia exclusiva, especialmente quando as lesões são extensas.

Long-term efficacy and literature review of liver transplant recipients with hepatic myelopathy / 中华器官移植杂志

Objective:To explore the long-term therapeutic efficacy and outcomes of liver transplantation for patients with hepatic myelopathy (HM).Methods:Retrospective analysis of 24 adult liver transplantation recipients due to HM at First Central Municipal Hospital from January 2006 to October 2022. HM was extensively classified by the severity of lower extremity symptoms, degree of muscle stiffness, capability for independent ambulation and muscle strength. Furthermore, their long-term outcomes were examined. From January 2000 to October 2022, the databases of China National Knowledge Infrastructure (CNKI) , Google Scholar, PubMed and Web of Science were searched with such keywords as "肝性脊髓病and肝移植" "Hepatic Myelopathy and Liver Transplantation" .Results:After liver transplantation, liver functions and blood ammonia normalized and most clinical symptoms improved. During a follow-up period of (12-190) months, 19 patients showed a lowered grade of HC as compared to pre-transplantation. Four cases achieved a complete recovery of extremity function. No change occurred in severity grade for the remaining 5 patients. However, 4 of them experienced varying degrees of improvement in muscle strength and independent walking capability. This review summarized the clinical characteristics and clinical outcomes of 17 patients from both domestic and international sources. Most of them experiences varying degrees of symptomatic improvements after liver transplantation (16 cases).Conclusions:This study has confirmed the effectiveness of liver transplantation for HM and its contribution to the long-term patient recovery.
