    Input: Objective To determine the effect of robotic-assisted gait training ( RAGT ) compared to conventional overground training . Methods Sixty patients with motor incomplete spinal cord injury ( SCI ) were included in a prospect i ve , r and omized clinical trial by comparing RAGT to conventional overground training . The RAGT group received RAGT three sessions per week at duration of 40 minutes with regular physiotherapy in 4 weeks . The conventional group underwent regular physiotherapy twice a day , 5 times a week . Main outcomes were lower extremity motor score of American Spinal Injury Association impairment scale ( LEMS ) , ambulatory motor index ( AMI ) , Spinal Cord Independence Measure III mobility section ( SCIM3-M ) , and walking index for spinal cord injury version II ( WISCI-II ) scale . Results At the end of rehabilitation , both groups showed significant improvement in LEMS , AMI , SCIM3-M , and WISCI-II . Based on WISCI-II , statistically significant improvement was observed in the RAGT group . For the remaining variables , no difference was found . Conclusion RAGT combined with conventional physiotherapy could yield more improvement in ambulatory function than conventional therapy alone . RAGT should be considered as one additional tool to provide neuromuscular reeducation in patient with incomplete SCI Background . Retraining walking following spinal cord injury using visually guided tasks may be especially efficacious because it engages the motor cortex , whose input may facilitate improvements in functional walking . Objectives . To contrast 2 methods of retraining , one emphasizing precise , visually guided walking over obstacles and on targets ( Precision Training ) , the other emphasizing mass practice of walking on a treadmill ( Endurance Training ) . Methods . A r and omized , single-blind , crossover design was used . Twenty-two participants , ≥7 months postinjury , were r and omly allocated to start with Precision or Endurance Training . Each phase of training was 5 times per week for 2 months , followed by a 2-month rest . Measures of walking speed , distance , skill , confidence , and depression were obtained before training , then monthly thereafter . Results . Both forms of training led to significant improvements in walking , with Endurance Training inducing bigger improvements in walking distance than Precision Training , especially for high-functioning walkers who had initial walking speeds > 0.5 m/s . The largest improvements in walking speed and distance occurred in the first month of Endurance Training , with minimal changes in the second month of training . In contrast , improvements in walking skill occurred over both months during both types of training . Retention of over ground walking speed , distance , and skill was excellent for both types of training . Conclusions . Intensive walking training in the chronic phase after spinal cord injury is effective in improving over ground walking . Visually guided tasks for training individuals with chronic spinal cord injury were not superior to mass practice on a treadmill BACKGROUND Functional electrical stimulation ( FES ) therapy has been shown to be one of the most promising approaches for improving voluntary grasping function in individuals with subacute cervical spinal cord injury ( SCI ) . OBJECTIVE To determine the effectiveness of FES therapy , as compared to conventional occupational therapy ( COT ) , in improving voluntary h and function in individuals with chronic ( ≥24 months post injury ) , incomplete ( American Spinal Injury Association Impairment Scale [ AIS ] B-D ) , C4 to C7 SCI . METHODS Eight participants were r and omized to the  intervention group  ( FES therapy ; n = 5 ) or the  control group ( COT ; n = 3 ) . Both groups received 39 hours of therapy over 13 to 16 weeks . The primary outcome measure was the Toronto Rehabilitation Institute-H and Function Test ( TRI-HFT ) , and the secondary outcome measures were Grade d Redefined Assessment of Strength Sensibility and Prehension ( GRASSP ) , Functional Independence Measure ( FIM ) self-care subscore , and Spinal Cord Independence Measure ( SCIM ) self-care subscore . Outcome assessment s were performed at baseline , after 39 sessions of therapy , and at 6 months following the baseline assessment . RESULTS After 39 sessions of therapy , the intervention group improved by 5.8 points on the TRI-HFT 's Object Manipulation Task , whereas the control group changed by only 1.17 points . Similarly , after 39 sessions of therapy , the intervention group improved by 4.6 points on the FIM self-care subscore , whereas the control group did not change at all . CONCLUSION The results of the pilot data justify a clinical trial to compare FES therapy and COT alone to improve voluntary h and function in individuals with chronic incomplete tetraplegia Introduction : Muscle atrophy , spasticity , and deformity are among long term complication of spinal cord injury ( SCI ) veterans . There are numerous studies evaluating effect of functional electrical stimulation on muscle properties of SCI people , but less research has focused on the benefits of passive cycling in the management of spasticity and improving ROM of lower limbs  in individuals with SCI . Aims : To evaluate the effect of electrical passive cycling on passive range of movement spasticity and electrodiagnostic parameters in SCI veterans . Methods : Sixty-four SCI veterans referred to two clinical and research center in Tehran were recruited in this prospect i ve clinical trial . The subjects were divided into two groups according to electrical passive cycling usage : ( 1 ) patients who did not use pedal exercise ( control group ) , ( 2 ) patients used Electrical passive cycling up to optimal level ( intervention group ) . Main outcome measures included hip , knee , and ankle range of motion , spasticity scale , and electrodiagnostic parameters including F-Wave Consistency , F-Wave Amplitude , H/M Ratio , F/M Ratio , H-Reflex Onset Latency , and H-Reflex Amplitude . Data were recorded at the time of receiving and 1 year after pedal exercise usage . Results : Sixty-four SCI patients including 95.3 % male , 4.7 % female with mean age 43 years old were included in this study . All patients except one suffered from complete SCI . The involved spinal levels were cervical ( 17.2 % ) , upper thoracic ( 34.4 % ) , lower thoracic ( 45.3 % ) , and lumbar ( 3.1 % ) . Spasticity scale decreased significantly after passive cycling in group 2 . Also hip , knee , and ankle ROM in group 2 were significantly improved after pedal exercise . There was a significant difference in H max/M max ( RT < ) and F/M ratio after versus before electric passive cycling system in group 2 . Conclusion : These findings suggest that passive rhythmic leg exercise can lead to decrease in spasticity , increase in passive ROM of lower limbs and improvement in electrodiagnostic parameters of spasticity in patients with SCI Background . About 75 % of persons with ASIA ( American Spinal Injury Association ) Impairment Scale C and D incomplete spinal cord injury ( SCI ) achieve walking ability . Objective . To compare a walking reeducation program using Lokomat with conventional overground training among individuals with incomplete SCI of both traumatic and nontraumatic etiology . Methods . A total of 80 participants from 3 to 6 months after onset admitted to 1 site for rehabilitation were included in a single-blind r and omized clinical trial of 2 parallel groups , with blind evaluation by independent observers . Patients received 40 walking reeducation sessions of equal time using a Lokomat program with overground practice or overground mobility therapy alone . Primary measurements of outcome were walking speed and the Walking Index for Spinal Cord Injury ( WISCI II ) . Secondary outcomes were the 6-minute walk test , locomotor section of the Functional Independence Measure , Lower Extremity Motor Score ( LEMS ) , Ashworth Scale , and Visual Analog Scale for pain . Results . No significant differences were found at entry between treatment groups . Walking speed for Lokomat ( 0.4 m/s [ 0.6 - 0.2 ] ) and overground therapy ( 0.3 m/s [ 0.5 - 0.2 ] ) groups did not differ . The WISCI II for the Lokomat group ( 16 [ 8.5 - 19 ] ) was better than for overground therapy ( 9 [ 8 - 16 ] ) . The 6-minute walk test and LEMS displayed significant differences in favor of Lokomat therapy but were not corrected for multiple comparisons . Conclusions . Robotic-assisted training was equivalent to conventional walk training in patients with a variety of nonprogressive spinal cord pathologies for walking speed , but the need for orthotics and assistive devices was reduced , perhaps because of greater leg strength in the robotic group [ Purpose ] To investigate the effects of transcutaneous electrical nerve stimulation ( TENS ) on pain in patients with spinal cord injury . [ Subjects and Methods ] Fifty-two spinal cord injury patients with central pain were r and omly allocated into two groups TENS and control with 26 subjects per group . The patients in TENS and control groups were treated with TENS and sham TENS for 20 min ( three times a week ) for 12 consecutive weeks , respectively . The two group ’s pain was assessed using visual analog scale ( VAS ) and the McGill Pain Question naire ( including pain rating index-total , pain rating index-affective , pain rating index-sensory , present pain intensity , and number of words chosen ) before and after the treatment . [ Results ] After the intervention , we found significant differences in VAS , pain rating index-total , pain rating index-affective , pain rating index-sensory , present pain intensity , and number of words chosen between the TENS group and the control group . [ Conclusion ] Our results suggest that TENS effectively decreases pain in patients with spinal cord injury Abstract Background / Objective : Limited research evidence is available to show the effectiveness of the many specific interventions provided in spinal cord injury ( SCI ) rehabilitation ; what is available typically focuses on effects of the full rehabilitation package but not specific therapy interventions , medical procedures , patient education , or counseling . Given the problems of conducting r and omized controlled trials ( RCTs ) in rehabilitation , practice -based evidence ( PBE ) research has been suggested as an alternative methodology for identifying which rehabilitation interventions are associated most strongly with positive outcomes , after controlling for patient differences . Using the PBE research methodology , the SCIRehab project attempts to " open the black box " of acute SCI rehabilitation , provide detailed information on treatments delivered by all rehabilitation disciplines , and contribute to outcomes -based guidelines for clinical decision-making . Methods : The SCIRehab project includes 1,500 patients with acute SCI , consecutively admitted to 1 of 6 US inpatient rehabilitation facilities . Details of the rehabilitation process are captured by clinicians from multiple disciplines documenting their interventions in h and held personal digital assistants after sessions with their patients . Outcome data are abstract ed from medical records ( clinical outcomes data ) and obtained from patient interviews at 6 and 12 months after injury . Extensive patient , injury , and other treatment characteristics are abstract ed from medical records . SCIRehab is the first research project to collect detailed information on individual interventions offered by the full rehabilitation team . Results : SCIRehab is the first research project to collect detailed information on individual interventions offered by the full rehabilitation team . These findings are presented in a series of 9 articles . Conclusions : To date , SCIRehab 's major contribution is a system for categorizing specific contributions of each discipline and a technology for documenting that detail . After data collection is complete , future manuscripts will relate those process elements to outcomes . The SCIRehab Project is an important step toward establishing outcomes -based guidelines for SCI rehabilitation Objective : To determine the clinical efficacy of functional electrical therapy in the rehabilitation of grasping function for quadriplegics . Study design : R and omized intervention-versus-control trial . Setting : Rehabilitation hospital for spinal cord injury in Toronto , Canada . Methods : A total of 21 people with new spinal cord injuries ranging from C3 to C7 were r and omly assigned to two groups : Control ( N=9 ) and Intervention ( N=12 ) . The intervention was functional electrical therapy , which consisted of repetitive grasping exercises using a neuroprosthesis that applied surface electrical stimulation to the arm to generate and /or assist grasping movements . It was applied by registered Occupational Therapists in a clinical setting . Main outcome measures were : Functional Independence Measure ( FIM ) , Spinal Cord Independence Measure ( SCIM ) , and the Rehabilitation Engineering Laboratory H and Function Test . Consumer perceptions of functional electrical therapy  were assessed via qualitative interviews . Results : Differences between the Control and Intervention groups could be observed although they are not significant due to an insufficient number of participants . Consumer perceptions were positive , including improved Activities of Daily Living and self-satisfaction . Conclusion : Functional electrical therapy has the potential to be an effective treatment modality to restore grasping function in quadriplegia . It can be implemented by occupational therapists in a clinical setting . Further research is required to establish suitable indications for participant selection . In addition , a larger number of participants is needed to demonstrate statistical significance of the Functional Electrical Therapy OBJECTIVE To study the application of partial weight-bearing ( PWB ) supported treadmill gait training augmented by functional electric stimulation ( FES ) in subjects with acute incomplete spinal cord injury ( SCI ) .
