Impacto de un Programa de Recuperación Funcional en Músculos Ventilatorios y Apendiculares en Pacientes Post-ventilación Mecánica por COVID-19 / Impact of a Functional Recovery Program on Ventilatory and Appendicular Muscles in Patients Post-mechanical Ventilation for COVID-19

Los pacientes con COVID-19 subsidiarios de ventilación mecánica (VM), evolucionan con consecuencias funcionales en la musculatura ventilatoria y apendicular que no necesariamente se abordan de manera diferenciada. El objetivo de esta investigación fue evaluar el impacto de un programa de recuperación funcional en estos pacientes y determinar si las intervenciones afectan de manera diferenciada a las funciones ventilatorias y musculatura apendicular, utilizando pruebas de bajo costo. Se evaluaron 47 pacientes con COVID-19 que estuvieron en VM. Posterior a una espirometría basal se les realizó; presión inspiratoria máxima (PIMáx), fuerza de prensión palmar (FPP), prueba de pararse y sentarse (PPS) y Prueba de caminata en 6 minutos (PC6m), antes y después del plan de intervención. Este programa incluyó ejercicios aeróbicos y de fuerza supervisados por dos sesiones semanales de 60 minutos durante 3 meses. Después del programa, se observaron mejoras significativas en la capacidad vital forzada (CVF), el volumen espiratorio en el primer segundo (VEF1) y la PIMáx. Se encontraron relaciones significativas entre estas mediciones y la distancia recorrida de la PC6m, la FPP y la PPS. En conclusión, el programa de recuperación funcional en pacientes con COVID-19 que requirieron VM, beneficia tanto la función ventilatoria como la fuerza muscular apendicular. Las pruebas de fuerza muscular apendicular pueden ser útiles para evaluar la recuperación ya que pueden entregar información diferenciada de sus rendimientos. Por último, se necesita más investigación para comprender mejor la respuesta de estos pacientes a la rehabilitación.

SUMMARY: Patients with COVID-19 requiring mechanical ventilation (MV) evolve with functional consequences in the ventilatory and appendicular muscles that are not necessarily addressed in a differentiated manner. The objective of this research was to evaluate the impact of a functional recovery program in these patients and determine if the interventions differentially affect ventilatory functions and appendicular muscles, using low- cost tests. 47 patients with COVID-19 who were on MV were evaluated. After a baseline spirometry, they were performed; maximum inspiratory pressure (MIP), handgrip strength (HGS), sit to stand test (STST) and 6-minute walk test (6MWT), before and after the intervention plan. This program included supervised aerobic and strength exercises for two weekly 60-minute sessions for 3 months. After the program, significant improvements were observed in forced vital capacity (FVC), expiratory volume in the first second (FEV1) and MIP. Significant relationships were found between these measurements and the distance traveled of the 6MWT, the HGS and the STST. In conclusion, the functional recovery program in patients with COVID-19 who required MV benefits both ventilatory function and appendicular muscle strength. Appendicular muscle strength tests can be useful to evaluate recovery since they can provide differentiated information about your performances. Finally, more research is needed to better understand the response of these patients to rehabilitation.

The efficacy of corticosteroid after facial nerve neurorrhaphy: a systematic review and meta-analysis of randomized controlled trial

Abstract Objectives: The benefit of corticosteroids following facial nerve neurorrhaphy in the setting of complete transection is questionable. This systematic review and meta-analysis aimed to evaluate corticosteroid efficacy on facial nerve regeneration and functional recovery after complete disruption and neurorrhaphy. Methods: Randomized controlled trials on both human and animal models from Ovid MEDLINE and Ovid EMBASE studying corticosteroid efficacy in complete facial nerve disruption followed by neurorrhaphy were included. Data were extracted and pooled for meta-analysis. The outcomes were evaluated from electrophysiology, histology, and functional recovery. However, no randomized controlled trial in human was performed. Possibly, performing human trials with histopathology may not be feasible in clinical setting. Results: Six animal studies (248 participants) met inclusion criteria. Electrophysiologic outcomes revealed no differences in latency (Standardized Mean Difference (SMD) = −1.97, 95% CI −7.38 to 3.44, p = 0.47) and amplitude (SMD = 0.37, 95% CI −0.44 to 1.18, p = 0.37) between systemic corticosteroids and controls. When analysis compared topical corticosteroid and control, the results provided no differences in latency (Mean Difference (MD)=0.10, 95% CI −0.04 to 0.24, p = 0.16) and amplitude (SMD = 0.01, 95% CI −0.08 to 0.10, p = 0.81). In histologic outcomes, the results showed no differences in axon diameter (MD = 0.13, 95% CI −0.15 to 0.41, p = 0.37) between systemic corticosteroid and control; however, the result in myelin thickness (MD = 0.06, 95% CI 0.04 to 0.08, p < 0.05) favored control group. When comparing systemic corticosteroid with control in eye blinking, the results favored control (MD= 1.33, 95% CI 0.60 to 2.06, p = 0.0004). Conclusions: This evidence did not show potential benefits of systemic or topical corticosteroid deliveries after facial nerve neurorrhaphy in complete transection when evaluating electrophysiologic, histologic, and functional recovery outcomes in animal models.

Pre-operative Factors Predicting Mortality in Six Months and Functional Recovery in Elderly Patients with Hip Fractures

@#Introduction: This study aimed to determine on-admission and perioperative factors predicting six-month mortality and functional recovery in Vietnamese patients with hip fracture. Materials and methods: Between April 2020 and July 2021, 118 patients participated in this prospective study. Patients’ data were collected from medical records. Harris hip score (HHS) was used to evaluate the functional recovery six months after fractures. The obtained data were analysed using a univariate and multivariate model. Results: The mean age of the participants was 79.5±9.4 years and 68.6% of the patients were female. The six-month mortality rate was 5.9% and independently associated with age (odds ratio (OR): 3.512, 95% confidence interval (CI) 1.538 – 8.019; P<0.001, patients aged >80 years vs those aged ≤80 years) and hypoproteinemia (OR: 2.859, 95% CI: 1.001 – 8.166, P=0.049). Among 111 survivors there were 66 (59.5%) of patients with a good functional recovery. Patients aged >80 years had a higher risk of poor functional outcome (OR: 3.167, 95% CI: 1.386 – 7.235, P: 0.006) compared to those aged ≤ 80 years. No significant correlations between other clinical (gender, body mass index, comorbidities, type of fractures or surgery, time until surgery) or laboratory parameters (anaemia, hyperglycemia, marked elevation of C reactive protein level, electrolyte abnormalities, elevated urea) and mortality or functional outcome were found. Conclusion: Advanced age is the most important factor affecting both mortality and functional outcome while hypoproteinemia is associated with a higher risk of mortality in elderly patients with hip fractures.

Quantitative Evaluation of the Corticospinal Tract on CT Predicts Functional Recovery after Lacunar Infarction of the Corona Radiata / The Japanese Journal of Rehabilitation Medicine

Objective：Although prediction of functional recovery after lacunar infarction is challenging, quantitative evaluation of brain imaging may be promising. In this article, we investigate association of the amount of corticospinal tract (CST) injury on Computed Tomography (CT) and functional recovery of lacunar infarction in the corona radiata.Methods：In 24 patients with lacunar infarction of the corona radiata, we investigated association of the amount of virtual CST injury with upper and lower limb motor function at 90 days after the stroke onset. The optimal area of the virtual CST to predict motor function was also determined. Finally, we evaluated whether the quantitative CST injury predicted practical motor function regarding activities of daily living.Results：The amount of virtual CST injury, evaluated with Hounsfield unit value of CT, was significantly associated with upper and lower limb function at 90 days after stroke onset. Among them, 6 mm radius CST circle for upper limb had the highest regression coefficient to predict Brunnstrom stage for the upper extremity (R2＝0.69), grip strength (R2＝0.52) and Simple Test for Evaluating Hand function (R2＝0.75). Also, 7 mm radius CST circle for lower limb had the highest regression coefficient to predict Brunnstrom stage for the lower extremity (R2＝0.51), weight bearing index (R2＝0.53) and Berg Balance Scale (R2＝0.52). These virtual CSTs predicted practical function including practical upper limb and ambulation.Conclusion：Quantitative evaluation of CST on CT predicted functional recovery after lacunar infarction of the corona radiata.

A metabolite of Danshen formulae (IDHP) induces angiogenesis and protects rat brains against focal ischemia via CaMKKβ/AMPK(Thr172)/eNOS(Ser1177) signaling / 中国药理学与毒理学杂志

OBJECTIVE Only limited number of drugs are currently available for treating ischemic stroke. Therapeu?tic angiogenesis has recently emerged as one of the most promising therapies for cerebral ischemic injury. Isopropyl-β-(3,4-dihydroxyphenyl)-α-hydroxypropanoate (IDHP) is a metabolite derived from the botanical formulation for Dantonic?. Here, we investigated the angiogenic efficacy of IDHP in cerebral ischemia. METHODS The in vivo effects of IDHP were evaluated in the C57BL/6 mouse Matrigel plug and rat transient middle cerebral artery occlusion (tMCAO) models. Primary human umbilical vein endothelial cells (HUVEC) and human brain microvascular endothelial cells (HBMEC) were used to explore the effects of IDHP on stimulating proliferation, migration and tube formation in vitro. ELISA and Western blotting were used to quantitate the release and expression of relevant target molecules and signaling path?ways. RESULTS IDHP reduced infarct volume and improved sensorimotor function in rats subjected to tMCAO by pro?moting angiogenesis, and promoted Matrigel neovascularization in mice. Moreover, IDHP produced a biphasic modula?tion on proliferation and migration both in HUVEC and HBMEC. It also induced tube formation in a 12-day HUVEC-HDF co-culture model and in Matrigel assays. IDHP-induced angiogenesis was accompanied by increased levels of p-AMPKα (Thr172) and p-eNOS (Ser1177) both in vitro and in vivo, and the decreased level of VEGF in rat brains on day 1 whereas enhanced level of VEGF on day 3 and 7 after tMCAO. Mechanistically, AMPK knockdown or pharmacologi?cally inhibiting AMPK and its upstream kinases (CaMKKβ) inhibited the eNOS phosphorylation induced by IDHP in HUVEC. Furthermore, selective eNOS inhibitor (L-NIO), selective CaMKKβ inhibitor (STO) and AMPKa inhibitor (Com?pound C) blocked the capillary-like tube formation in the co-culture model induced by IDHP (10 nmol · L-1). CONCLU?SION Collectively, these findings showed that IDHP protected rats from cerebral ischemia-reperfusion injury by promot?ing angiogenesis via activating CaMKKβ/AMPK(Thr172)/eNOS(Ser1177) signaling, and suggest it to be a promising new drug candidate for the prevention and/or treatment of cerebral ischemia and other vascular occlusive diseases.

La fractura de cadera es una patología cuya incidencia ha aumentado drásticamente en proporción al aumento de la población adulta mayor. En los últimos años, los longevos superan los 100 años y son ellos quienes mayoritariamente presentan esta urgencia trauma-tológica, que casi en la totalidad de los casos se presenta posterior a caídas de bajo impacto y requieren resolución quirúrgica. A continuación, se presenta el caso de una paciente femenina centenaria con fractura de cadera que fue sometida a manejo quirúrgico con posterior recuperación funcional parcial. Se resalta que la edad no es una contraindicación quirúrgica.

Hip fracture is a pathology whose incidence has increased dramatically accordingly with population aging. In recent years, the long-lived have exceeded 100 years. They are who mostly present this traumatic emergency, which almost in all cases occurs after low-impact falls and requires surgical resolution.We expose the case of a centennial female patient presenting with a hip fracture and undergoing surgical orthopaedic repair. She had a partial functional recovery. Our review shows that age is not a surgical contraindication.

Intervención integral en el ictus / Comprehensive intervention in stroke

Introducción: se mantiene el debate sobre qué tipos de intervenciones para la recuperación del ictus ofrecen mejores resultados para el paciente. Objetivo: evaluar el efecto de una intervención integral durante seis meses sobre la recuperación funcional en pacientes con ictus. Métodos: la muestra estuvo compuesta por 42 participantes con ictus: un grupo experimental (N = 22) con una media de edad de 52,68 años (DE = 14,39) que recibió una intervención integral, intensiva y multidisciplinar, y un grupo control (N = 20) con una media de edad de 56,20 años (DE = 14,82) que no recibió este tipo de intervención. Se valoraron los siguiente índices de severidad del ictus: Escala de Coma de Glasgow, Escala Canadiense, estancia en Unidad de Cuidados Intensivos, signos de enclavamiento uncal, signos de hipertensión endocraneal, volumen del hematoma/área isquémica, desplazamiento de línea media, necesidad de cirugía y tiempo total de hospitalización. Ambos grupos eran equivalentes en estos índices de gravedad. El grado de funcionalidad fue medido con la aplicación de la escala Functional Independence Measure and Functional Assessment Measure. Esta prueba se aplicó al inicio de la intervención y 6 meses después. Resultados: se observó una evolución positiva en ambos grupos en todas las áreas de la escala. La intervención integral y un menor tiempo total de hospitalización se relacionaron con una mejor recuperación funcional en el ictus. Conclusiones: se sugiere la necesidad de realizar estrategias de rehabilitación integral en los pacientes con ictus(AU)

Introduction: debate is currently underway about what types of stroke recovery interventions are more beneficial for patients. Objective: evaluate the effect of a six-month comprehensive intervention on the functional recovery of stroke patients. Methods: the study sample was 42 stroke patients: an experimental group (N = 22), mean age 52.68 years (SD = 14.39), who received a comprehensive intensive multidisciplinary intervention, and a control group (N = 20), mean age 56.20 years (SD = 14.82), who did not receive this type of intervention. The following stroke severity indices were applied: Glasgow Coma Scale, Canadian Scale, intensive care unit stay, uncal latching signs, endocranial hypertension signs, hematoma volume / ischemic area, midline displacement, need for surgery and total hospital stay time. These severity indices were similar in the two groups. Degree of functionality was gauged with the scales Functional Independence Measure and Functional Assessment Measure. This test was applied at the start of the intervention and 6 months later. Results: both groups had a positive evolution in all the areas of the scale. The comprehensive intervention and a shorter total hospital stay were associated to better functional recovery from stroke. Conclusions: the need is suggested to implement comprehensive rehabilitation strategies in stroke patients(AU)

Oscillating field stimulation inhibits neuroinflammatory response and promotes functional recovery after spinal cord injury in rats / 中国组织工程研究

BACKGROUND: Oscillating field stimulation (OFS) is an emerging technology that has been used to treat spinal cord injury (SCI) with promising therapeutic effects. The application of electric current to the injured spinal cord is known to promote healing and tissue regeneration. However, the mechanisms by which OFS leads to SCI recovery are not yet fully understood. OBJECTIVE: To investigate whether OFS can promote the recovery of neurological function by reducing neuroinflammatory responses after SCI in rats. METHODS: Sixty-three female Sprague-Dawley rats were randomized into an experimental group, a SCI group and a sham operation group. Rats in the sham operation group only underwent laminectomy without damaging the spinal cord, and animal models of thoracic (T9-T10) SCI were established in the SCI and experimental groups. The OFS device was implanted into the injured site in the experimental group, followed by continuous electrical stimulation. Basso-BettieBresnahan score was used to evaluate the recovery of motor function after SCI in rats. In addition, hematoxylin-eosin staining was used to test tissue repair and inflammatory cell recruitment. The number of astrocytes and microglia was examined by immunofluorescence staining. The study protocol was approved by the Animal Ethics Committee of Anhui Medical University, with an approval No. LLSC20190736. RESULTS AND CONCLUSION: The Basso-Bettie-Bresnahan score of the experimental group was significantly higher than that of the SCI group. Hematoxylineosin staining results showed that the number of inflammatory cells in the injured site was considerably reduced in the experimental group compared with the SCI group. The results of immunofluorescence detection showed that the number of glial fibrillary acidic protein positive cells and microglia in the experimental group was dramatically lower than that in the SCI group at different time after surgery. These findings indicate that OFS can improve the motor function of lower limbs, promote tissue repair, reduce inflammatory cell recruitment, and inhibit the activation of astrocytes and microglia after spinal cord injury in rats. OFS can promote the recovery of neurological function by inhibiting inflammatory response after SCI.

Long-term intensive family rehabilitation training for postoperative functional recovery in elderly hip fracture patients / 中国组织工程研究

BACKGROUND: Hip fracture can result in a high functional disability rate in elderly patients. Traditional rehabilitation pays more attentions to rehabilitation training during hospitalization, instead of family rehabilitation training out of hospital. Intensive family rehabilitation training for 6 months has been proven to be an effective method, but its longer-term effect still needs further study. OBJECTIVE: To explore the effect of long-term intensive family rehabilitation training on postoperative functional recovery in elderly hip fracture patients. METHODS: Eighty-nine elderly hip fracture patients who were treated with surgery were prospectively enrolled, and randomized into an experimental group (n=42) and a control group (n=47). The control group patients were treated with traditional rehabilitation training, and the patients in the experimental group were treated with long-term intensive family rehabilitation training. Functional exercises in the experimental group were guided, and the rehabilitation scheme was adjusted in time using network tools. All the patients were followed up for 12 months, and their functional recovery was assessed at 3, 6, and 12 months postoperatively by the activity of daily living score, 6-minute walking test, the hip Harris score, the functional independent measure score and the MOS 36-Item Short-Form Health Survey (SF-36) score. The study protocol was implemented in line with the ethic requirements of the Sixth People’s Hospital of Chengdu, and each patient was fully informed of the study procedures. RESULTS AND CONCLUSION: Patients’ function gradually recovered in both group postoperatively. The activity of daily living score, functional independent measure score, 6-minute walking test, Hip Harris score, and SF-36 score of the experimental group were significantly better than those in the control group at 3, 6, and 12 months postoperatively (P<0.05). To conclude, long-term intensive family rehabilitation training for elderly hip fractures can improve patients’ daily life ability and quality of life; however, the rehabilitation program and its efficacy still require further research.

Effect of artificial tiger bone powder on functional recovery of brittle fracture / 中国综合临床

Objective To investigate the auxiliary effect of artificial tiger bone powder on the fragile fracture healing and functional recovery.Methods From June 2014 to June 2015,64 patients with fragile fracture in the second Hospital of Tangshan were randomly divided into treatment and control groups,32 cases in each group.All the selected patients were given routine treatment of fracture.The treatment group was given artificial tiger bone powder,while the control group was given vitamin D and calcium carbonate.The clinical fracture healing time of the selected patients were recorded.At the beginning and 3,6 months after treatment,the Barthel Index ( BI) and functional independent measure ( FIM) were recorded.Results There was no significant difference in general condition, BI score and FIM score between the two groups before treatment.At the 3rd and 6th month after treatment,the BI scores were(( 65.74 ± 7.94 ),( 76.05 ±8.07 ) value),and FIM scores were(( 76.61± 9.08),(( 87.91 ± 6.76) valu)],those in the treatment group were higher than those in the control group( BI:( 61.12 ± 8.67), ( 71.25 ± 8.32) value and FIM:(71.03±9.34),(79.01±7.32) value),( P＜0.05).The the fracture healing time in the treatment group was shorter((12.78±2.09) weeks) than that in the control group((13.94± 2.32) weeks),( t＝2.101,P＜0.05).Conclusion Artificial tiger bone powder can shorten the healing time of fracture, which has auxiliary effect on the healing of fragile fracture.It can promote the functional recovery of fragile fracture patients,and improve their life and activity.

Effect of different joint injury types on function recovery after floating knee operation / 中华创伤杂志

Objective To compare the function recovery of multiple injuries combined with floating knee joint injury and simple knee joint injury,and to analyze the risk factors.Methods A retrospective case control study was conducted to analyze the clinical data of 41 patients with multiple injuries combined with Blake and McBryde Ⅱ A floating knee injury admitted to Xijing Hospital of Air Force Medical University from June 2011 to June 2017.There were 26 males and 15 females,aged 18-76 years,with an average of 34.5 years.There were 25 patients with simple knee joint injury and and 16 patients with multi-joint combined injury involving knee joint and ipsilateral hip joint or ankle joint injury.Surgical fixation was performed in different parts by external fixation,intramedullary nail and plate screw fixation.According to the Kalstr(o)m and Olerud functional evaluation criteria,the excellent and good rate of postoperative functional recovery was compared between the two groups.The surgical fixation methods of the two groups were compared.Logistic regression analysis was performed on the influencing factors of functional recovery.Results The patients were followed up for 1-7 years,with an average of 3 years.The excellent and good rate of overall functional recovery in the two groups was 68％,and the rate was 84％ in simple knee injury group and 44％ in multi-joint combined injury group (P ＜ 0.01).There was no significant difference in the ratio of intramedullary nail and plate screw fixation between the two groups (P ＞ 0.05),while the proportion of the external fixation in the multi-joint combined injury group [31％ (5/16)] was significantly higher than that in the simple knee joint injury group [16％ (4/25)] (P ＜ 0.05).Logistic regression analysis showed that the rate of external fixation was an independent factor affecting the postoperative function (OR =0.15,P ＜ 0.01).Conclusions The postoperative function in multi-joint injury patients is poorer than in the single joint injury patients.The higher rate of using external fixation in multi-joint injury patients is a risk factor.For Blake and McBryde Ⅱ A floating knee injury combined with multi-joint injury,less external fixation should be used,so as to improve the postoperative function.

Microelectric Treatment by Transcutaneous Electrical Nerve Stimulation in a Rat Model of Acute Spinal Cord Injury / 대한척추외과학회지

STUDY DESIGN: Animal study. OBJECTIVES: To investigate the effects of microelectric treatment by transcutaneous electrical nerve stimulation (TENS) on functional recovery and histological changes in a rat model of spinal cord injury (SCI). SUMMARY OF LITERATURE REVIEW: The effects of TENS on spasticity and its underlying mechanisms remain unclear. MATERIALS AND METHODS: SCI was induced by a 1.5-mm impactor with 200,000–260,000 dyne after laminectomy. Rats were divided into the following groups: group I (normal control), group II (microelectric treatment of 0 A), group III (microelectric treatment of 100 µA for 1 hr/day), group IV (microelectric treatment of 400 µA for 1 hr/day), and group V (microelectric treatment of 400 µA for 24 hr/day). After inducing SCI, rats were assessed by a sensory test with von Frey filaments and the locomotor recovery test (BBB rating scale) at 1, 4, 7, 14, 21, and 28 days. To evaluate spinal cord damage, histopathological studies were performed with hematoxylin and eosin. Brain-derived neurotrophic factor (BDNF) and TrkB immunohistochemistry studies were performed at 28 days. RESULTS: In groups IV and V, the BBB score had significantly improved on days 21 and 28 after SCI, and the TENS-treated groups showed significant neuronal recovery. After SCI, groups IV and V showed a significant recovery of locomotor function and the motor sensory response of the withdrawal threshold to 3.5 g. In addition, necrotic tissue and cystic spaces in the spinal cord were significantly reduced and BDNF/TrkB-positive cells were highly expressed in groups III, IV, and V. CONCLUSIONS: Microelectric treatment can play a role in facilitating the recovery of locomotion following SCI.

Neurofeedback Treatment on Depressive Symptoms and Functional Recovery in Treatment-Resistant Patients with Major Depressive Disorder: an Open-Label Pilot Study

BACKGROUND: We evaluated the effects of neurofeedback as an augmentation treatment on depressive symptoms and functional recovery in patients with treatment-resistant depression (TRD). METHODS: We included 24 adult patients with TRD and 12 healthy adults. 24 TRD patients were assigned to the neurofeedback augmentation group (n = 12) and the medication-only (treatment as usual [TAU]) group (n = 12). The neurofeedback augmentation group underwent combined therapy comprising medication and 12–24 sessions of neurofeedback training for 12 weeks. To assess the serum levels of brain-derived neurotrophic factor (BDNF) in both groups, pre- and post-treatment blood samples were obtained. Patients were evaluated using the Hamilton Depression Rating Scale (HAM-D), Beck Depression Inventory (BDI), Clinical Global Impression-Severity (CGI-S), 5-level version of European Quality of Life Questionnaire 5-Dimensional Classification (EQ-5D-5L), and Sheehan Disability Scale (SDS) at baseline, and at the 1-, 4-, and 12-week. RESULTS: From baseline to week 12, neurofeedback training reduced mean scores on HAM-D, BDI-II, CGI-S, and SDS, and increased mean EQ-5D-5L tariff score. In the neurofeedback augmentation group, the response and remission rates were 58.3% and 50.0%, respectively, at week 12. Changes in HAM-D, EQ-5D-5L tariff score, and SDS were significantly larger in the neurofeedback group than in the medication-only (TAU) group. No significant difference in BDNF level was found pre- vs. post-treatment in any of the groups. CONCLUSION: Despite the small sample size, these results suggest that neurofeedback treatment may be effective as an augmentation treatment, not only for depressive symptoms, but also for functional recovery, in patients with TRD.

Effects of Hand Training During the Aftereffect Period of Low-Frequency rTMS in Subacute Stroke Patients

OBJECTIVE: To investigate the effects of hand training using low-frequency repetitive transcranial magnetic stimulation (rTMS) within the aftereffect period on hand function in patients with subacute stroke. METHODS: The subacute stroke patients with hand weaknesses were divided randomly into two groups. Patients in the intervention group underwent hand training within the aftereffect period, that is, immediately after receiving low-frequency rTMS treatment. Patients in the control group underwent hand training 2 hours after the low-frequency rTMS treatment. A manual function test (MFT) for ‘grasp and pinch’ and ‘hand activities’; a manual muscle test (MMT) for ‘grasp’, ‘release’, and ‘abductor pollicis brevis (APB)’; and the Modified Ashworth Scale for finger flexion were performed and measured before and immediately after combined therapy as well as 2 weeks after combined therapy. RESULTS: Thirty-two patients with hand weakness were enrolled in this study. The intervention group patients showed more improvements in grasp MMT and MMT APB tested immediately after combined therapy. However, the changes in all measurements were not significantly different between the two groups 2 weeks after the combined therapy. In both groups, hand functions improved significantly immediately after combined therapy and 2 weeks after combined therapy. CONCLUSION: Hand training immediately after low-frequency rTMS showed more rapid improvement in the motor power of hands than hand training conducted 2 hours after low-frequency rTMS. Our results suggest that conducting hand training immediately after low-frequency rTMS could be an improved useful therapeutic option in subacute stroke patients.

Curcumin Increase the Expression of Neural Stem/Progenitor Cells and Improves Functional Recovery after Spinal Cord Injury

OBJECTIVE: To investigates the effect of curcumin on proliferation of spinal cord neural stem/progenitor cells (SC-NSPCs) and functional outcome in a rat spinal cord injury (SCI) model.METHODS: Sixty adult male Sprague-Dawley rats were randomly and blindly allocated into three groups (sham control group; curcumin treated group after SCI; vehicle treated group after SCI). Functional recovery was evaluated by the Basso, Beattie, and Bresnahan (BBB) scale during 6 weeks after SCI. The expression of SC-NSPC proliferation and astrogliosis were analyzed by nestin/Bromodeoxyuridine (BrdU) and Glial fibrillary acidic protein (GFAP) staining. The injured spinal cord was then examined histologically, including quantification of cavitation.RESULTS: The BBB score of the SCI-curcumin group was better than that of SCI-vehicle group up to 14 days (p < 0.05). The co-immunoreactivity of nestin/BrdU in the SCI-curcumin group was much higher than that of the SCI-vehicle group 1 week after surgery (p < 0.05). The GFAP immunoreactivity of the SCI-curcumin group was remarkably lower than that of the SCI-vehicle group 4 weeks after surgery (p < 0.05). The lesion cavity was significantly reduced in the curcumin group as compared to the control group (p < 0.05).CONCLUSION: These results indicate that curcumin could increase the expression of SC-NSPCs, and reduce the activity of reactive astrogliosis and lesion cavity. Consequently curcumin could improve the functional recovery after SCI via SC-NSPC properties.
