Primary objective: To evaluate effectiveness of phenol blocks of peripheral nerves in reducing spasticitybrain injured and spinal cord injured patients.Secondary objectives: To measure the change in the range of motion after phenol blocks to peripheralnerves, to identify the electrophysiological changes and to study the cost effectiveness and side effects ofphenol blocks.Study design: Descriptive studySetting: Tertiary referral centre, India.Methods: This study was conducted from March 2000 to January 2002 among 20 patients with spasticity.Spasticity was measured by modified Ashworth scale and range of motion was measured with a standardgoniometer on 1st, 7th, 14th and 21st days of the study. Nerve conduction studies, gait analysis, and functionalindependence measure was measured on 1st and 21st day of the study. Nerve blocks were done on 7th and14th day of the study with 0.5% bupivacaine and 6% phenol in water respectively.Results: 20 patients were included in the study, out of which 85% had spinal cord injury and 15% patientshad brain injury sequelae. Spasticity measured by modified Ashworth scale, showed a statistically significantreduction with neurolysis. Following obturator neurolysis abduction of hip joint improved significantly andwith posterior tibial neurolysis there was significant improvement in dorsiflexion and plantar flexion rangeof the ankle joint. Functional improvement measured with the FIM score also showed statistically significantimprovement after neurolysis. H reflex amplitude was significantly reduced following neurolysis. Therewas a statistically significant reduction in the consumption of systemic medications for spasticity followingthe injection.Conclusion: Range of motion in neighboring joints improved significantly after blockade of spasticity usingPhenol neurolysis. There was statistically significant reduction in the amplitude of the H reflex. Therewere no major adverse effects following neurolysis with phenol and it was found to be significantly costeffective when compared to systemic antispastic medications.

Genu Recurvatum is a deformity of knee joint that tends to push it backwards by excessive extension in tibio-femoral joints. This poses a significant challenge because of technical difficulties and a high incidence of recurrence. This report describes a 63 years old male diagnosed as post-polio residual paralysis who showed excessive genu recurvatum of his left knee during long standing and walking. An Articulated Knee Hyperextension Orthosis (KAFO) was tried to check its effectiveness in terms of gait and energy expenditure.

Context: The Spinal Cord Independence Measure is a comprehensive functional rating scale for individuals with spinal cord lesion (SCL)., Objective: To validate the scores of the three subscales of SCIM IV, the fourth version of SCIM, using advanced statistical methods., Study Design: Multi-center cohort study., Setting: Nineteen SCL units in 11 countries., Methods: SCIM developers created SCIM IV following comments by experts, included more accurate definitions of scoring criteria in the SCIM IV form, and adjusted it to assess specific conditions or situations that the third version, SCIM III, does not address. Professional staff members assessed 648 SCL inpatients, using SCIM IV and SCIM III, at admission to rehabilitation, and at discharge. The authors examined the validity and reliability of SCIM IV subscale scores using Rasch analysis., Results: The study included inpatients aged 16-87 years old. SCIM IV subscale scores fit the Rasch model. All item infit and most item outfit mean-square indices were below 1.4; statistically distinct strata of abilities were 2.6-6; most categories were properly ordered; item hierarchy was stable across most clinical subgroups and countries. In a few items, however, we found misfit or category threshold disordering. We found SCIM III and SCIM IV Rasch properties to be comparable., Conclusions: Rasch analysis suggests that the scores of each SCIM IV subscale are reliable and valid. This reinforces the justification for using SCIM IV in clinical practice and research.

Objective: Ankle foot orthosis (AFO) commonly prescribed to manage foot-drop following stroke restricts ankle mobility. Commercially available functional electrical stimulation (FES) is an expensive alternative to achieve desired dorsiflexion during swing phase of the gait cycle. An in-house cost-effective innovative solution was designed and developed to address this problem.The aim of the study was to compare spatiotemporal gait characteristics of patients with foot-drop following stroke using commercially available FES against in-house developed versatile single sensor-based FES., Material and Methods: Ten patients with cerebrovascular accident of at least 3 months duration and ambulant with/without AFO were recruited prospectively. They were trained with Device-1 (Commercial Device) and Device-2 (In-house developed, Re-Lift) for 7 h over 3 consecutive days with each device. Outcome measures included timed-up-and-go-test (TUG), six-minute-walk-test (6MWT), ten-meter-walk-test (10MWT), physiological cost index (PCI), instrumented gait analysis derived spatiotemporal parameters, and patient satisfaction feedback questionnaire. We calculated intraclass correlation between devices and median interquartile range. Statistical analysis included Wilcoxon-signed-rank-test and F-test ( P < 0.05 was considered statistically significant). Bland Altman and scatter plots were plotted for both devices., Results: Intraclass correlation coefficient for 6MWT (0.96), 10MWT (0.97), TUG test (0.99), and PCI (0.88) reflected high agreement between the two devices. Scatter plot and Bland Altman plots for the outcome parameters showed good correlation between two FES devices. Patient satisfaction scores were equal for both Device-1 and Device-2. There was statistically significant change in swing phase ankle dorsiflexion., Conclusions: The study demonstrated good correlation between commercial FES and Re-Lift suggestive of the utility of low-cost FES device in clinical setting., Competing Interests: There are no conflicts of interest., (© 2023 Published by Scientific Scholar on behalf of Journal of Neurosciences in Rural Practice.)

Background: Management of foot-drop following stroke can be addressed with ankle-foot orthosis (AFO) or functional electrical stimulation (FES) of the peroneal nerve. There is limited evidence regarding the efficacy of FES as a substitute for a conventional ankle-foot orthosis., Objective: The aim of this study was to compare efficacy of FES against AFO in management of foot-drop in patients following stroke., Materials and Methods: Twenty patients (ten per group) were enrolled in this prospective crossover trial. Group A patients received gait training with AFO during first week followed by training with FES during second week and vice-versa for group B. Outcome parameters following AFO/FES training included Ten-meter, Six-minute walk test and spatiotemporal gait parameters. Patient satisfaction level was assessed using feedback questionnaire. Friedman test and Wilcoxon signed-rank test were performed to compare outcomes between barefoot, AFO and FES. The P value < 0.05 was considered statistically significant., Results: Nineteen males and one female aged 45.5 ± 9.45 years were recruited. Statistically significant improvement was observed in Ten-meter and Six-minute walk tests, gait speed, Timed up and go test (TUG), stance-swing ratio and single-limb support among users of FES as compared to AFO and barefoot. There was no statistical difference observed in other gait parameters. Physiological cost index (PCI) showed trend in improvement among FES users. Patient satisfaction scores were higher for FES users., Conclusions: Quantitative and qualitative results were in favour of FES as compared to AFO and barefoot suggesting that FES can be a potential orthotic intervention in hemiplegic patients., Competing Interests: None

Background: It is unknown whether assessment of autonomic pathway integrity in newly injured traumatic cervical spinal cord injury (SCI) patients contributes to their neurological prognosis., Objective: The objective is to investigate the relationship of heart rate variability (HRV) and sympathetic skin response (SSR) at initial evaluation of American Spinal Injury Association Impairment Scale (AIS) A/B tetraplegic patients, with their short-term neurological recovery., Methods: In this prospective cohort study, short-term HRV indices and SSR to supra-lesional stimuli were computed in 24 acute traumatic cervical AIS A/B SCI patients at admission for rehabilitation. The relationship of these autonomic parameters with motor and sensory score improvement, AIS grade improvement, and time taken for recovery was tested, respectively, with Spearman's correlation coefficient test, Fisher's exact test, and Kaplan-Meier analysis., Results: SSR was present in 11 (45.8%) patients at initial evaluation. After rehabilitation, 5 (20.8%) patients improved from AIS A/B to AIS C (greater recovery), while the rest remained at AIS A/B (lesser recovery). Both AIS improvement and mean time for 'greater' recovery did not associate with the presence/absence of SSR. Further, HRV indices did not correlate with improvement in motor or sensory scores., Conclusions: Interim neurological recovery was not related to autonomic parameters of short-term HRV indices and SSR in the AIS A/B tetraplegic patients of our study. Interestingly, about half of the patients with clinically complete SCI had evidence of preserved autonomic function. Our data add to the knowledge base of autonomic findings in cervical SCI patients and will promote research relating neurophysiological parameters and recovery.

Introduction  Infertility in men with spinal cord injury (SCI) occurs due to combination of factors like erectile dysfunction, ejaculatory failure, and semen abnormalities. Penile vibratory stimulation (PVS) is a known method of treatment for anejaculation. Predicting successful outcome of PVS depends on several clinical factors, which assess the intactness of the neural arc pertaining to the spinal ejaculation pattern generator. This study reports the clinical predictors for successful candidacy for a PVS trial in males with SCI. Methods  Twenty-three males with SCI, satisfying the inclusion criteria, were recruited in this prospective observational study. Participants underwent two trials of PVS with single high-amplitude vibrator. The clinical predictors recorded were neurological level, superficial abdominal reflex, cremasteric reflex, bulbocavernosus reflex, plantar reflex, ankle jerk, knee jerk, lower abdominal sensation, and hip flexor response. In addition, somatic responses during PVS were recorded and corelated. Participants who had successful ejaculation were "responders" and the others were termed as "nonresponders." Binary logistic regression analysis of the clinical parameters was done to compare responders against nonresponders. Results  Of the twenty-three males (mean age 33.2 ± 6.8 years) with paraplegia, all four persons with neurological level above T9 had successful ejaculation with PVS. Among all the clinical parameters in the study, presence of somatic responses showed statistical significance in predicting successful ejaculation ( p -value = 0.02). Conclusion  This study reports that in men with SCI, along with the level of injury, somatic responses and other clinical reflexes, should be considered concurrently to predict the outcome of vibrator assisted ejaculation., Competing Interests: Conflict of Interest None declared., (Association for Helping Neurosurgical Sick People.

Study Design: Prospective observational study., Purpose: To evaluate bone turnover markers (BTMs) in individuals with acute spinal cord injury (SCI) and to compare the results with those of healthy controls and postmenopausal females., Overview of Literature: SCI significantly impacts bone health. Change in bone mineral density appears 6 months after SCI and rapid bone loss during the acute phase is often underestimated, resulting in osteoporosis and a high risk of sublesional fractures. However, few studies have evaluated BTMs in the Indian SCI population. Despite a high risk of fracture, there are no guidelines for the diagnosis, monitoring, and management of SCI-induced osteoporosis., Methods: Twenty patients within 1 month of traumatic SCI who had been admitted to a tertiary care rehabilitation center were included in this study. Serum BTMs, C telopeptide (CTX) as a bone resorption marker, and osteocalcin as a bone formation marker, were serially measured at baseline, and 3 and 6 months after SCI. BTMs of SCI patients were compared with those of a control group of age-matched healthy males, premenopausal females, and a vulnerable group of postmenopausal females., Results: BTMs were significantly elevated in patients with SCI, with maximum levels observed at the 3rd month of injury. At baseline, the bone resorption marker CTX was approximately 3 times higher in SCI patients than in the control male population and premenopausal females, and about double that of postmenopausal females. The rise in the bone formation marker was marginal in comparison to that of the bone resorption marker. BTMs were persistently elevated and did not reach the normative range until the 6th month of SCI., Conclusions: Raised bone resorption markers in comparison to bone formation markers indicate hyper-resorption-related bone loss following acute SCI. Markedly elevated bone resorption markers in the SCI population, compared with those in control and vulnerable groups, emphasize the need for early bone health monitoring and management.

Background: Neuronal tissue has a limited potential to self-renew or get repaired after damage. Cell therapies using stem cells are promising approaches for the treatment of central nervous system (CNS) injuries. However, the clinical use of embryonic stem cells is limited by ethical concerns and other scientific consequences. Bone marrow mesenchymal stromal cells (BM-MSC) could represent an alternative source of stem cells for replacement therapy. Indeed, many studies have demonstrated that MSCs can give rise to neuronal cells as well as many tissue-specific cell phenotypes., Purpose: Motor recovery by transplantation of bone marrow MSCs in rat models of spinal cord injury (SCI)., Methods: Bone marrow was collected from the femur of albino Wistar rats. MSCs were separated using the Ficoll-Paque density gradient method and cultured in Dulbecco's Modified Eagle Medium supplemented with 20% fetal bovine serum. Cultured MSC was characterized by immunohistochemistry and flow cytometry and neuronal-induced cells were further characterized for neural markers. Cultured MSCs were transplanted into the experimentally injured spinal cord of Wistar rats. Control (injured, but without cell transplantation) and transplanted rats were followed up to 8 weeks, analyzed using the Basso, Beattie, Bresnahan (BBB) scale and electromyography (EMG) for behavioral and physiological status of the injured spinal cord. Finally, the tissue was evaluated histologically., Results: Rat MSCs expressed positivity for a panel of MSC markers CD29, CD54, CD90, CD73, and CD105, and negativity for hematopoietic markers CD34, CD14, and CD45. In vitro neuronal transdifferentiated MSCs express positivity for β III tubulin, MAP2, NF, NeuN, Nav1.1, oligodendrocyte (O4), and negativity for glial fibrillary acid protein. All the treated groups show promising hind-limb motor recovery BBB score, except the control group. There was increased EMG amplitude in treated groups as compared to the control group. Green fluorescent protein (GFP)-labeled MSC survived and differentiated into neurons in the injured spinal cord, which is responsible for functional recovery., Conclusion: Our results demonstrate that BM-MSC has the potential to repair the injured cord in rat models of SCI. Thus, BM-MSC appears to be a promising candidate for cell-based therapy in CNS injury.

Study Design: Olfactory ensheathing cells (OECs) from rat olfactory mucosa were cultured, characterized, and transplanted into a rat model of spinal cord injury (SCI)., Purpose: To evaluate different doses of OECs in a rat model of SCI., Overview of Literature: SCI causes permanent functional deficit because the central nervous system lacks the ability to perform spontaneous repair. Cell therapy strategies are being explored globally. The clinical use of human embryonic stem cell is hampered by ethical controversies. Alternatively, OECs are a promising cell source for neurotransplantation. This study aimed to evaluate the efficacy of different doses of allogenic OEC transplantation in a rat model of SCI., Methods: OECs were cultured from the olfactory mucosa of Albino Wistar rats; these cells were characterized using immunohistochemistry and flow cytometry. Rats were divided into five groups (n=6 rats each). In each group, different dosage (2×105, 5×105, 10×105, and >10×105) of cultured cells were transplanted into experimentally injured spinal cords of rat models. However, in the SCI group, only DMEM (Dulbecco's modified Eagle's medium) was injected. Rats were followed up upto 8 weeks post-transplantation. The outcome of transplantation was assessed using the Basso, Beattie, Bresnahan (BBB) scale; motor-evoked potential studies; and histological examination., Results: Cultured cells expressed 41% of p75NTR, a marker for OEC, and 35% of anti-fibronectin, a marker for olfactory nerve fibroblast. These cells also expressed S100β and glial fibrillary acid protein of approximately 75% and 83%, respectively. All the transplanted groups showed promising BBB scores for hind-limb motor recovery compared with the SCI group (p<0.05). A motor-evoked potential study showed increased amplitude in all the treated groups compared with the SCI. Green fluorescent protein-labeled cells survived in the injured cord, suggesting their role in the transplantation-mediated repair. Transplantation of 5×105 cells showed the best motor outcomes among all the doses., Conclusions: OECs demonstrated a therapeutic effect in rat models with the potential for future clinical applications.

Background: Spinal cord injury (SCI) leads to permanent functional deficits because the central nervous system lacks the ability for spontaneous repair. Cell therapy strategies offered a hope in neurological repair. The clinical use of human embryonic stem cell transplantation is hampered by scientific and ethical controversies. Olfactory ensheathing cells (OECs)/bone marrow mesenchymal stem cell (MSC) is a promising cell source for autologous neurotransplantation devoid of ethical concerns., Aim: This study aimed to evaluate the combined therapeutic effect of OEC, MSC, and chondroitinase in SCI rat models., Materials and Methods: Adult female albino Wistar rats were divided into ten groups, n = 6 rats in each group and control ( n = 11). T10 level laminectomy was done in anesthetized rats to create drop-weight SCI. Both OEC and MSC were transplanted on the 9 th day following SCI as a combined therapy with different dosage of 2 × 10 5 , 5 × 10 5 , 10 × 10 5 , and >10 × 10 5 at a ratio of 1:1 with/without chondroitinase (0.2 U). One group of SCI rats was treated with chondroitinase alone 0.2 U. Dulbecco's Modified Eagle medium was injected in control rats. The outcome of transplantation was assessed using Basso, Beattie, Bresnahan (BBB) scale and motor-evoked potential studies., Results: All the treated groups showed hindlimb motor recovery in BBB score except control group ( P < 0.05). All the three combinations showed better results than OEC + MSC groups in hindlimb motor recovery. In dose-response relationship, 5- and 10-lakh combinations elicited increased functional recovery than 2- and more than 10-lakh combinations. However, chondroitinase alone demonstrated a highest BBB score than any other groups., Conclusions: Chondroitinase/cell combinations have a therapeutic beneficial effect in SCI., Competing Interests: There are no conflicts of interest.

Spinal cord injury (SCI) is a devastating condition with loss of motor and sensory functions below the injury level. Cell based therapies are experimented in pre-clinical studies around the world. Neural stem cells are located intra-cranially in subventricular zone and hippocampus which are highly invasive sources. The olfactory epithelium is a neurogenic tissue where neurogenesis takes place throughout the adult life by a population of stem/progenitor cells. Easily accessible olfactory neuroepithelial stem/progenitor cells are an attractive cell source for transplantation in SCI. Globose basal cells (GBCs) were isolated from rat olfactory epithelium, characterized by flow cytometry and immunohistochemically. These cells were further studied for neurosphere formation and neuronal induction. T10 laminectomy was done to create drop-weight SCI in rats. On the 9 th day following SCI, 5 × 10 5 cells were transplanted into injured rat spinal cord. The outcome of transplantation was assessed by the Basso, Beattie and Bresnahan (BBB) locomotor rating scale, motor evoked potential and histological observation. GBCs expressed neural stem cell markers nestin, SOX2, NCAM and also mesenchymal stem cell markers (CD29, CD54, CD90, CD73, CD105). These cells formed neurosphere, a culture characteristics of NSCs and on induction, differentiated cells expressed neuronal markers βIII tubulin, microtubule-associated protein 2, neuronal nuclei, and neurofilament. GBCs transplanted rats exhibited hindlimb motor recovery as confirmed by BBB score and gastrocnemius muscle electromyography amplitude was increased compared to controls. Green fluorescent protein labelled GBCs survived around the injury epicenter and differentiated into βIII tubulin-immunoreactive neuron-like cells. GBCs could be an alternative to NSCs from an accessible source for autologous neurotransplantation after SCI without ethical issues., Competing Interests: None declared

Objective: To assess the effect of interactive video gaming (IVG) with Nintendo Wii (Wii) supplemented to conventional therapy in rehabilitation of children with cerebral palsy (CP)., Design: Randomized, controlled, assessor-blinded study., Participants: Children with CP; 10 children each in the control and intervention groups., Intervention: IVG using Wii, given as a supplement to conventional therapy, for 45 min per day, 6 days a week for 3 weeks. The children in the control group received conventional therapy alone., Outcome Measures: Posture control and balance, upper limb function, visual-perceptual skills, and functional mobility., Results: Significant improvement in upper limb functions was seen in the intervention group but not in the control group. Improvements in balance, visual perception, and functional mobility were not significantly different between control and intervention groups., Conclusions: Wii-based IVG may be offered as an effective supplement to conventional therapy in the rehabilitation of children with CP.

Background and Purpose: Phantom limb pain (PLP) can be disabling for nearly two thirds of amputees. Hence, there is a need to find an effective and inexpensive treatment that can be self administered. Among the non-pharmacological treatment for PLP, transcutaneous electrical nerve stimulation (TENS) applied to the contralateral extremity and mirror therapy are two promising options. However, there are no studies to compare the two treatments. The purpose of this study is to evaluate and compare mirror therapy and TENS in the management of PLP in subjects with amputation., Methods: The study was an assessor blinded randomized controlled trial conducted at Physiotherapy Gymnasium of Physical Medicine and Rehabilitation Department, Christian Medical College, Vellore. Twenty-six subjects with PLP consented to participate. An initial assessment of pain using visual analogue scale (VAS) and universal pain score (UPS) was performed by a therapist blinded to the treatment given. Random allocation into Group I-mirror therapy and Group II-TENS was carried out. After 4 days of treatment, pain was re-assessed by the same therapist. The mean difference in Pre and Post values were compared among the groups. The change in pre-post score was analyzed using the paired t test., Results: Participants of Group I had significant decrease in pain [VAS ( p = 0.003) and UPS ( p = 0.001)]. Group II also showed a significant reduction in pain [VAS ( p = 0.003) and UPS ( p = 0.002)]. However, no difference was observed between the two groups [VAS ( p = 0.223 and UPS ( p = 0.956)]., Discussion: Both Mirror Therapy and TENS were found to be effective in pain reduction on a short-term basis. However, no difference between the two groups was found. Substantiation with long-term follow-up is essential to find its long-term effectiveness.

Objectives: To demonstrate reduction in detrusor overactivity using surface electrical stimulation of posterior tibial nerve (PTN) or dorsal penile nerve (DPN) in patients with spinal cord injury (SCI)., Design: Patients with SCI with symptoms of urinary urgency/leaks, with cystometrogram (CMG) proven detrusor overactivity were recruited in this study. Ten persons with observable F-wave from tibial nerve were included in the PTN group. Five persons who had F-wave absent but preserved bulbocavernosus reflex were included in the DPN group. Stimulation was given at 20 Hz, 10-40 mA for 20 minutes/session/day for 14 consecutive days. Detrusor overactivity was recorded using CMG on days 1 and 15., Settings: Rehabilitation Institute, Department of Physical Medicine and Rehabilitation, Christian Medical College and Hospital, Vellore, TN, India., Participants: Patients with SCI., Interventions: Surface stimulation of peripheral nerves for reduction of detrusor overactivity., Outcome Measures: Qualitative analysis using voiding diary data and quantitative analysis using CMG data comparing pre- and post-intervention., Results: P value obtained from voiding chart was 0.021 for PTN and 0.062 for DPN. P value obtained from CMG data was not significant in both groups. In one subject, treatment was extended to 4 weeks and further improvement in voiding diary was seen., Conclusions: In this pilot study of 15 patients, voiding chart data showed statistically significant improvement following PTN stimulation and trend of improvement following DPN stimulation. However, the CMG data were not statistically significant in this sample population. Further studies with larger, appropriately powered sample size would be helpful to demonstrate the associations of symptoms with CMG data.

Background: Upper extremity strengthening and gait training with orthoses form a major part of inpatient rehabilitation of paraplegic patients in developing countries. This helps to overcome architectural barriers and limited wheelchair accessible environment in the community., Objectives: To evaluate the changes in physiological properties of the Triceps Brachii muscle following exercise training in individuals with paraplegia. The authors also explored the correlation between muscle property changes and gait parameters using orthoses in paraplegic persons., Methods: Twelve subjects with complete paraplegia and neurological level of injury (NLI) from T9 to L1, underwent exercise training for a mean 64.1 ± 4.1 days. Triceps brachii was chosen as the sample muscle. Variables like arm circumference, time to fatigue and mean power frequency (MF) (surface EMG parameter), were recorded at the beginning and the end of training, during a sub-maximal isometric elbow extension. Non-parametric tests were used to assess statistical significance between the two recordings. Additionally, gait parameters like walking speed and distance (with the help of orthoses) were obtained and compared with the above variables, to determine impact of upper extremity strengthening on gait improvements in such patients., Results: Statistically significant changes were noted in bilateral arm circumferences (p= 0.003 bilaterally) and MF drop, expressed as percentage (right p= 0.04, left p= 0.01), indicative of better muscle resilience and adaptation. Significant positive correlation was observed between `time to fatigue' and the orthoses-aided total walking distance (right ρ = 0.65, left ρ = 0.69)., Conclusions: Exercise training induces noticeable changes in the muscles of upper extremities favoring better muscle adaptation. Furthermore, positive correlation between `time to fatigue' and (orthotic) aided walking distance highlights the positive impact of strengthening program on gait parameters in paraplegic patients. These findings are important and relevant in developing countries with environmental barriers. Upper extremity strengthening should be included in the rehabilitation of paraplegic patients who are being trained for ambulation with orthoses.

The spinal cord injury leads to enervation of normal tissue homeostasis ultimately leading to paralysis. Until now there is no proper cure for the treatment of spinal cord injury. Recently, cell therapy in animal spinal cord injury models has shown some progress of recovery. At present, clinical trials are under progress to evaluate the efficacy of cell transplantation for the treatment of spinal cord injury. Different types of cells such as pluripotent stem cells derived neural cells, mesenchymal stromal cells, neural stem cells, glial cells are being tested in various spinal cord injury models. In this review we highlight both the advances and lacuna in the field of spinal cord injury by discussing epidemiology, pathophysiology, molecular mechanism, and various cell therapy strategies employed in preclinical and clinical injury models and finally we discuss the limitations and ethical issues involved in cell therapy approach for treating spinal cord injury.

Objective: To compare the effectiveness of body weight-supported treadmill training and body weight-supported overground training for improving gait and strength in people with traumatic incomplete tetraplegia., Design: Assessor blinded randomized trial., Setting: Rehabilitation institute of a tertiary care teaching hospital in India., Participants: Sixteen participants with traumatic motor incomplete tetraplegia and within two years of injury., Interventions: Participants were randomised to one of two groups: body weight-supported overground training on level ground and body weight-supported treadmill training. Both groups received 30 minutes of gait training per day, five days a week for eight weeks. In addition, both groups received regular rehabilitation which included flexibility, strength, balance, self care and functional training., Outcome Measures: The primary outcome measure was the Walking Index for Spinal Cord Injury (/20 points) and the secondary outcome was the Lower Extremity Muscle Score (/50 points)., Results: There was no statistically significant between group differences in the Walking Index for Spinal Cord Injury [mean difference=0.3points; 95% CI (-4.8 to 5.4); p=0.748] or the Lower Extremity Muscle Score [mean difference=0.2 points; 95% CI (-3.8 to 5.1); p=0.749]., Conclusions: Gait training with body weight-supported overground training is comparable to treadmill training for improving locomotion in people with traumatic incomplete tetraplegia., (© The Author(s) 2014.)

Objective: To assess the survival in persons with traumatic spinal cord injury (SCI) receiving structured follow-up in South India., Design: Retrospective study., Setting: Rehabilitation center., Participants: Persons with traumatic SCI (N=490) residing within a 100-km radius of the institute who were managed and regularly followed up by the rehabilitation center between the years 1981 and 2011., Interventions: Not applicable., Main Outcome Measures: Survival rates and mortality risk factors. Measures were estimated using the product limit (Kaplan-Meier) method and the Cox model., Results: The survival rate after SCI was 86% after 5 years, 71% after 15 years, and 58% after 25 years. Survival of persons with complete high cervical injury is substantially low compared with other levels of SCI. Level of injury and extent of lesion (Frankel classification and/or American Spinal Injury Association Impairment Scale) play a significant role in predicting survival of this population., Conclusions: Survival rates of regularly followed-up persons with SCI from this study show promising results, though survival rates are lesser when compared with studies from developed countries. Better understanding of the predictors, causes of deaths, comprehensive rehabilitation, community integration, and regular follow-up could possibly assist in improving survival rates., (Copyright © 2014 American Congress of Rehabilitation Medicine.

Objectives: In the past few decades, variety of foetal, embryonic and adult stem and progenitor cells have been tried with conflicting outcome for cell therapy of central nervous system injury and diseases. Cellular characteristics and functional plasticity of Globose basal stem cells (GBCs) residing in the olfactory epithelium of rat olfactory mucosa have not been studied in the past by the neuroscientists due to unavailability of specific markers for GBCs. In the present research, we standardized some techniques to isolate GBCs from rat olfactory epithelium in pure form using a highly selective GBC-III antibody passaged through fluorescence activated cell sorter (FACS). We also characterized these cells immunohistologically using various pluripotent stem cell markers. This work also throws some light on ionic channels present on these stem cells which are responsible for their neuron induction potential., Materials and Methods: Globose basal stem cells were isolated from rat olfactory epithelium using GBC-III antibody and were characterized as multipotent stem cells using various neural progenitor markers. Ionic channels on GBCs were studied with voltage clamping., Results: GBCs could be isolated in pure (99% purity) form and were found to be stained positive for all neural progenitor cell markers. Voltage gated Na(+) channels were completely absent, which proves the unexcitable nature of GBCs. Leaky K(+) channels were found to be present on the GBC which was of no significance., Conclusion: This research work can be helpful in understanding the nature of these stem cells and utilising them in future as potent candidates for neuro-regenerative therapies.

Introduction: Olfactory mucosa which is situated in the roof of the nasal cavity possesses an extremely peculiar and exceptional type of pluripotent stem cells called Globose Basal Cells (GBCs) which help in lifelong regeneration of the olfactory mucosa. Previous literature doesn't provide much knowledge on the cytological, histochemical and electrophysiological properties of these cells, as they have never been isolated in pure form., Material and Methods: Olfactory mucosa was obtained from six Albino Wistar rats by using standardized surgical and chemical separation procedures. GBCs were isolated by using different chemical, surgical and fluorescent techniques., Results: In this research work, we standardized the techniques for isolating these stem cells in pure form from rat olfactory mucosa by tagging them with GBC-III antibody and separating them from other epithelial cells by using Fluorescence Activated Cell Sorter (FACS). GBC-III antibody is a mouse monoclonal IgM antibody which recognizes a 40 kDa surface antigen, which is a laminin receptor surface protein present on the GBCs. It is a highly specific marker for GBCs, unlike the earlier antibodies used, like GBC-I, which were nonspecific markers for GBCs and showed positive reactions, even with Horizontal Basal Cells (HBCs), sustentacular cells (Sus) and duct cells. This study also standardized the techniques for surgically excising the olfactory mucosa from the nasal septum and chemically separating the olfactory epithelium from the lamina propria., Conclusion: GBCs are an important group of cells which can be exploited in future to study and treat neuro-degenerative disorders like multiple sclerosis, brain ischaemia, etc. and spinal cord trauma, as they reside in a niche similar to the microenvironment in the central nervous system and have the similar ectodermal development as the neuronal and non-neuronal cells of the CNS. Moreover, olfactory epithelium is easily accessible for autologous transplantation of GBCs for different CNS disorders.

Background: Gorham's disease of the spine is very rare and usually associated with poor prognosis. Till date very few cases have been reported in the literature. It is characterized by osseous invasion by angiomatous vascular mass without skip areas, eventually causing lysis of affected bone. Morbidity and mortality are high in those with spinal and/or visceral involvement. Neurological complications increase the mortality to 33% whereas with chylothorax, mortality increases to more than 50%., Objectives: To describe the clinical course and the challenges in planning and implementing effective rehabilitation services for management of patients with Gorham's disease of the spine., Methods: We report two patients with Gorham's disease who had neurological deficits secondary to spinal cord involvement, and their rehabilitation perspectives., Results: Both patients achieved satisfactory ambulation and functional outcomes., Conclusion: Multiple revision surgeries may be required to ensure spinal stability. When working with these patients, one must remain vigilant about spinal stability as well as about possible serious pulmonary complications, and be prepared to make appropriate management decisions when necessary.

Objective: The study aims to characterise the electrodiagnostic findings of patients with traumatic brachial plexus injuries (BPIs) in India and to analyse the association between aetiologies and levels of injuries., Methods: A total of 111 consecutive electrodiagnostic studies done between January 2009 and June 2011 on persons with traumatic BPI were retrospectively analysed., Setting: Electrodiagnostic Laboratory, Department of Physical Medicine and Rehabilitation in a tertiary care university teaching hospital in South India., Main Outcome Measures: Nerve conduction velocities and electromyography (EMG) to locate the level of BPI, Dumitru and Wilbourne scale to assess the severity of BPI., Results: We studied 106 males and five females, ranging from 11 to 59 years of age. All but one had unilateral BPI. Motorcycle crashes were the most frequent cause (n=64, 58%). Isolated supraclavicular injury was found in 98 arms (88%) and infraclavicular injury in seven arms (6%). Root-level injuries were more common in motorcycle crashes and occupation-related trauma, while trunk-level injuries were more often found in automobile crashes, falls, bicycle-related trauma and penetrating wounds. Pan root (C5-T1) involvement was more common in the motorcycle trauma group (74%). There was no significant association between aetiologies and levels of BPIs. A total of 73 (65%) plexus injuries were of 'severe' category as per Dumitru and Wilbourn scale., Conclusions: Motorcycle crash is the most common cause of traumatic BPIs. Supraclavicular injury is the rule in most cases. Proper attention needs to be given to differentiate the mild to moderate injuries from the severe injuries with EMG techniques since most of the cases are severe. There was no significant association found between aetiologies and levels of injury., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Background: Olfactory ensheathing cells (OEC) are considered to be the most suitable cells for transplantation therapy in the central nervous system (CNS) because of their unique ability to help axonal regrowth and remyelination in the CNS. However, there are conflicting reports about the success rates with OEC., Aim: This study was undertaken to evaluate the therapeutic effect of OEC in rat models using different cell dosages., Material and Methods: OECs harvested from the olfactory mucosa of adult white Albino rats were cultured. Spinal cord injury (SCI) was inflicted at the lower thoracic segment in a control and test group of rats. Two weeks later, OECs were delivered in and around the injured spinal cord segment of the test group of the rats. The outcome in terms of locomotor recovery of limb muscles was assessed on a standard rating scale and by recording the motor-evoked potentials from the muscles during transcranial electrical stimulation. Finally, the animals were sacrificed to assess the structural repair by light microscopy., Statistical Analysis: Wilcoxon signed rank test and Mann-Whitney U-test were used to compare the data in the control and the test group of animals. A P value of <0.05 was considered significant., Results: The study showed a moderate but significant recovery of the injured rats after OEC transplantation (P=0.005)., Conclusion: Transplantation of OECs along with olfactory nerve fibroblasts improved the motor recovery in rat models with SCI.

The objective of this study was to compare the therapeutic response of intravesical oxybutynin, propantheline, and capsaicin in the treatment of neurogenic detrusor overactivity. Carried out in the Department of Physical Medicine and Rehabilitation at a university teaching hospital in India, patients acted as their own controls. Oxybutynin 5 mg in solution or propantheline 15 mg in solution and capsaicin were instilled intravesically in each patient. Urodynamic studies were done before and after the intravesical instillation of each drug. The nonparametric tests were used for statistical analysis. The efficacy of intravesical capsaicin in the treatment of neurogenic detrusor overactivity was statistically significant for reflex volume (RV) (p = 0.018), cystometric capacity (CC) (p = 0.0440), leak volume (LV) (p = 0.000), and leak frequency (LF) (p = 0.009). The Kruskal-Wallis test for paired sample comparing pre- and post-LV and LF for intravesical capsaicin was significant at 2nd week (p = 0.002 and 0.054, respectively). There was a significant difference in therapeutic response between intravesical oxybutynin, propantheline, and capsaicin in the treatment of detrusor overactivity for LV and LF at 2nd week (p = 0.017 and 0.003, respectively). When comparing responses of oxybutynin and propantheline, more subjects demonstrated improvement with intravesical propantheline than oxybutynin for RV, detrusor leak point pressure (LPP), clean intermittent catheterization volume (CICV), and LV. This study suggests that intravesical agents may be used as effective adjuvants in the management of incontinence due to neurogenic detrusor overactivity following spinal cord injury.

We report a case of unilateral hydronephrosis following urethral catheterization in a patient with T6 complete paraplegia at the Physical Medicine and Rehabilitation Department in a tertiary care teaching hospital, India. Diagnosis was established by an abdominal ultrasound. The misplaced catheter tip was withdrawn from the ureteric orifice and hydronephrosis was resolved. Foley's catheterization, a widely practiced clinical procedure, is not without its attendant risks of an inadvertent placement in the ureter leading to transient hydronephrosis. Inadequate drainage through a catheter should thus alert one to this potentially hazardous complication that can be diagnosed by an early ultrasound. This complication can be avoided by gently tugging on the catheter after inflating the catheter bulb.

Glucose intolerance and dyslipidaemias have been reported among paraplegics and tetraplegics. In this study we determined the lipid profiles and the glucose tolerance in a group of 48 persons with spinal cord lesions who had been rehabilitated in our Department of Physical Medicine and Rehabilitation. This non-randomised, descriptive study was conducted as part of the annual medical follow-up of these individuals. Hypertension was observed in only 6% of the subjects. Fasting hyperglycemia was observed in 19% and glucose intolerance in 23% of the subjects. Total cholesterol was abnormal in 2%, but 58% had low levels of high density lipoprotein (HDL). 10% of the subjects had raised low density lipoprotein (LDL) levels. The cardioprotective HDL fraction may remain very low even while the total cholesterol level is within normal limits, and unless a lipid profile estimation is done, this group of individuals who are at cardiovascular risk may remain undetected. We conclude that glucose intolerance and dyslipidaemias are common among paraplegic and tetraplegic individuals, and these metabolic derangements may contribute to increased cardiovascular morbidity.

Meralgia paresthetica is an entrapment neuropathy from compression of lateral femoral cutaneous nerve of the thigh as it passes under the inguinal ligament. The entrapment produces pain, paresthesia, and sensory loss over the anterolateral aspect of the thigh, without motor loss. The etiology of this condition is often obscure and the pathogenesis is thought to be an entrapment of this nerve at the inguinal ligament where it pierces the fascia to reach the skin. Rarely, retroperitoneal lymphomas or other neoplasms can mimic symptoms of meralgia paresthetica. We report a case of a 60-year-old man who presented with clinical features of meralgia paresthetica. On investigation, he was found to have a secondary malignant deposit in the iliac crest from an adenocarcinoma of the lung. This neuropathy, although often caused by a benign lesion, can at times be the presenting symptom of a malignancy.
