Socio-ecological Barriers to Leisure Time Physical Activity in Spanish Wheelchair Users With Spinal Cord Injury: Associations With Sociodemographic Characteristics and Functional Independence.

OBJECTIVE: (1) To assess prevalence and severity of socio-ecological barriers to leisure time physical activity (LTPA) in a sample of adults with spinal cord injury (SCI); (2) to examine the association of these barriers with sociodemographic characteristics and functional independence (FI); and (3) to explore which socio-ecological levels of barriers might be associated with LTPA. DESIGN: Cross-sectional study. SETTING: Neurorehabilitation Hospital specialized in SCI. PARTICIPANTS: 207 wheelchair users with SCI living in the community who attended a comprehensive check-up (22.7% women, 47.5±10.7 mean age; N=207). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The short version of the Barriers to Physical Activity Questionnaire for People with Mobility Impairments was used to measure socio-ecological barriers to LTPA. The Spinal Cord Independence Measure III was used to measure FI. The Physical Activity Recall Assessment for People with SCI was used to quantify LTPA. Several multiple linear regression models were computed to examine the associations between socio-ecological barriers and sociodemographic factors, LTPA and FI. RESULTS: A high prevalence of barriers to LTPA was found. Seven of these barriers (2 intrapersonal, 3 organizational, and 2 community) were present for >60% of the participants. Intrapersonal and organizational barriers had a higher effect on participants with lower FI and women. Interpersonal barriers were higher for older participants and with lower FI, while community barriers were higher for unemployed participants. Finally, intrapersonal and interpersonal barriers were negatively associated with LTPA, and FI revealed as a moderator of the intrapersonal barriers-LTPA relation. CONCLUSIONS: Given their high prevalence and their association with LTPA, the development of interventions targeting socio-ecological barriers to LTPA in people with SCI becomes crucial. The associations of these barriers with FI and sociodemographic characteristics should also be considered for these interventions to be as specific and effective as possible.

Transcutaneous Cervical Spinal Cord Stimulation Combined with Robotic Exoskeleton Rehabilitation for the Upper Limbs in Subjects with Cervical SCI: Clinical Trial.

(1) Background: Restoring arm and hand function is a priority for individuals with cervical spinal cord injury (cSCI) for independence and quality of life. Transcutaneous spinal cord stimulation (tSCS) promotes the upper extremity (UE) motor function when applied at the cervical region. The aim of the study was to determine the effects of cervical tSCS, combined with an exoskeleton, on motor strength and functionality of UE in subjects with cSCI. (2) Methods: twenty-two subjects participated in the randomized mix of parallel-group and crossover clinical trial, consisting of an intervention group (n = 15; tSCS exoskeleton) and a control group (n = 14; exoskeleton). The assessment was carried out at baseline, after the last session, and two weeks after the last session. We assessed graded redefined assessment of strength, sensibility, and prehension (GRASSP), box and block test (BBT), spinal cord independence measure III (SCIM-III), maximal voluntary contraction (MVC), ASIA impairment scale (AIS), and WhoQol-Bref; (3) Results: GRASSP, BBT, SCIM III, cylindrical grip force and AIS motor score showed significant improvement in both groups (p ≤ 0.05), however, it was significantly higher in the intervention group than the control group for GRASSP strength, and GRASSP prehension ability (p ≤ 0.05); (4) Conclusion: our findings show potential advantages of the combination of cervical tSCS with an exoskeleton to optimize the outcome for UE.

Diaphragm Pacing in Patients with Spinal Cord Injury: A European Experience.

BACKGROUND: Patients with high spinal cord injury (SCI) are unable to breathe on their own and require mechanical ventilation (MV). The long-term use of MV is associated with increased morbidity and mortality. In patients with intact phrenic nerve function, patients can be partially or completely removed from MV by directly stimulating the diaphragm motor points with a diaphragm pacing system (DPS). OBJECTIVES: We describe our multicenter European experience using DPS in SCI patients who required MV. METHODS: We conducted a retrospective study of patients who were evaluated for the implantation of DPS. Patients evaluated for DPS who met the prospectively defined criteria of being at least 1 year of age, and having cervical injury resulting in a complete or partial dependency on MV were included. Patients who received DPS implants were followed for up to 1 year for device usage and safety. RESULTS: Across 3 centers, 47 patients with high SCI were evaluated for DPS, and 34 were implanted. Twenty-one patients had 12 months of follow-up data with a median DPS use of 15 h/day (interquartile range 4, 24). Eight patients (38.1%) achieved complete MV weaning using DPS 24 h/day. Two DPS-related complications were surgical device revision and a wire eruption. No other major complications were associated with DPS use. CONCLUSIONS: Diaphragm pacing represents an attractive alternative stand-alone treatment or adjunctive therapy compared to MV in patients with high SCI. After a period of acclimation, the patients were able to reduce the daily use of MV, and many could be completely removed from MV.

Cervical Electrical Neuromodulation Effectively Enhances Hand Motor Output in Healthy Subjects by Engaging a Use-Dependent Intervention.

Electrical enabling motor control (eEmc) through transcutaneous spinal cord stimulation is a non-invasive method that can modify the functional state of the sensory-motor system. We hypothesize that eEmc delivery, together with hand training, improves hand function in healthy subjects more than either intervention alone by inducing plastic changes at spinal and cortical levels. Ten voluntary participants were included in the following three interventions: (i) hand grip training, (ii) eEmc, and (iii) eEmc with hand training. Functional evaluation included the box and blocks test (BBT) and hand grip maximum voluntary contraction (MVC), spinal and cortical motor evoked potential (sMEP and cMEP), and resting motor thresholds (RMT), short interval intracortical inhibition (SICI), and F wave in the abductor pollicis brevis muscle. eEmc combined with hand training retained MVC and increased F wave amplitude and persistency, reduced cortical RMT and facilitated cMEP amplitude. In contrast, eEmc alone only increased F wave amplitude, whereas hand training alone reduced MVC and increased cortical RMT and SICI. In conclusion, eEmc combined with hand grip training enhanced hand motor output and induced plastic changes at spinal and cortical level in healthy subjects when compared to either intervention alone. These data suggest that electrical neuromodulation changes spinal and, perhaps, supraspinal networks to a more malleable state, while a concomitant use-dependent mechanism drives these networks to a higher functional state.

Clinical effects of intrathecal administration of expanded Wharton jelly mesenchymal stromal cells in patients with chronic complete spinal cord injury: a randomized controlled study.

BACKGROUND AIMS: Spinal cord injury (SCI) represents a devastating condition leading to severe disability related to motor, sensory and autonomic dysfunction. Stem cell transplantation is considered a potential emerging therapy to stimulate neuroplastic and neuroregenerative processes after SCI. In this clinical trial, the authors investigated the safety and clinical recovery effects of intrathecal infusion of expanded Wharton jelly mesenchymal stromal cells (WJ-MSCs) in chronic complete SCI patients. METHODS: The authors designed a randomized, double-blind, crossover, placebo-controlled, phase 1/2a clinical trial (NCT03003364). Participants were 10 patients (7 males, 3 females, age range, 25-47 years) with chronic complete SCI (American Spinal Injury Association A) at dorsal level (T3-11). Patients were randomly assigned to receive a single dose of intrathecal ex vivo-expanded WJ-MSCs (10 × 106 cells) from human umbilical cord or placebo and were then switched to the other arm at 6 months. Clinical evaluation (American Spinal Injury Association impairment scale motor and sensory score, spasticity, neuropathic pain, electrical perception and pain thresholds), lower limb motor evoked potentials (MEPs) and sensory evoked potentials (SEPs), Spinal Cord Independence Measure and World Health Organization Quality of Life Brief Version were assessed at baseline, 1 month, 3 months and 6 months after each intervention. Urodynamic studies and urinary-specific quality of life (Qualiveen questionnaire) as well as anorectal manometry, functional assessment of bowel dysfunction (Rome III diagnostic questionnaire) and severity of fecal incontinence (Wexner score) were conducted at baseline and at 6 months after each intervention. RESULTS: Intrathecal transplantation of WJ-MSCs was considered safe, with no significant side effects. Following MSC infusion, the authors found significant improvement in pinprick sensation in the dermatomes below the level of injury compared with placebo. Other clinically relevant effects, such as an increase in bladder maximum capacity and compliance and a decrease in bladder neurogenic hyperactivity and external sphincter dyssynergy, were observed only at the individual level. No changes in motor function, spasticity, MEPs, SEPs, bowel function, quality of life or independence measures were observed. CONCLUSIONS: Intrathecal transplantation of human umbilical cord-derived WJ-MSCs is a safe intervention. A single intrathecal infusion of WJ-MSCs in patients with chronic complete SCI induced sensory improvement in the segments adjacent to the injury site.

Espasticidad en la patología neurológica. Actualización sobre mecanismos fisiopatológicos, avances en el diagnóstico y tratamiento / Spasticity in neurological pathologies. An update on the pathophysiological mechanisms, advances in diagnosis and treatment

INTRODUCCIÓN: La espasticidad es un signo clínico frecuente en personas con enfermedades neurológicas que afecta a la movilidad y causa graves complicaciones: dolor, limitación articular, contracturas y úlceras por presión, que conllevan una afectación significativa de la funcionalidad del individuo y de su calidad de vida. OBJETIVO: Revisar la integración, la descripción y la interpretación crítica de la evidencia científica más reciente sobre la variabilidad clínica de la espasticidad y los síntomas asociados, los distintos mecanismos fisiopatológicos y su relevancia en el abordaje diagnóstico y terapéutico. DESARROLLO: Se realizó una búsqueda de las publicaciones científicas sobre los distintos aspectos de la espasticidad agrupados en dos categorías magistrales: patologías cerebral y medular; y se revisaron aspectos epidemiológicos, clínicos y fisiopatológicos, el diagnóstico clínico e instrumental, y el abordaje fisioterapéutico, farmacológico y quirúrgico de la espasticidad en cada grupo de patologías. CONCLUSIÓN: La espasticidad se relaciona con lesiones estructurales y cambios neuroplásticos maladaptativos que determinan una importante variabilidad en su expresión clínica. Aunque su diagnóstico presenta importantes limitaciones, el uso de herramientas de diagnóstico clínico y neurofisiológico encaminadas al abordaje diferencial en las patologías neurológicas de origen cerebral y medular podría optimizar la eficacia de las terapias de la espasticidad

INTRODUCTION: Spasticity is a frequent clinical sign in people with neurological diseases that affects mobility and causes serious complications: pain, joint limitation, muscular contractions and bed sores, which have a significant effect on the individual's functionality and quality of life. AIM: To review the integration, description and critical interpretation of the most recent scientific evidence on the clinical variability of spasticity and associated symptoms, the different pathophysiological mechanisms and their relevance in the diagnostic and therapeutic approach. DEVELOPMENT: A search was conducted in the scientific publications on the different aspects of spasticity grouped into two main categories: cerebral and spinal cord pathologies. The epidemiological, clinical and pathophysiological aspects, clinical and instrumental diagnoses, and the physiotherapeutic, pharmacological and surgical approach to spasticity in each group of pathologies were all reviewed. CONCLUSION: Spasticity is related to structural lesions and maladaptive neuroplastic changes that determine an important variability in its clinical expression. Although its diagnosis presents important limitations, the use of clinical and neurophysiological diagnostic tools aimed at achieving different approaches in cases of neurological pathologies originating in the brain and in the spinal cord could optimise the effectiveness of spasticity therapies

Lesión medular por intento de suicidio, perfil psiquiátrico y discapacidad funcional / Spinal cord injury due to suicide attempt, psychiatric profile and functional disability

Introducción. Estudios realizados en otros países señalan que el 1,6-3% de las lesiones medulares se adquieren por intento de autolisis, y la mayoría se producen por precipitación. Objetivos. Determinar la frecuencia de intento de suicidio como causa de lesión medular en un hospital de neurorrehabilitación y describir las características de estos pacientes en términos psiquiátricos y de discapacidad funcional. Pacientes y métodos. Estudio retrospectivo en el que se revisaron todos los pacientes con lesión medular por intento de autolisis en un período de 15 años en un hospital de neurorrehabilitación. Resultados. El intento de autolisis ocasionó el 2% de las lesiones medulares en la muestra (n = 61). El 93% de los pacientes estaba diagnosticado de patología psiquiátrica y el 26% había realizado tentativas previas. Aunque el 60% estaba vinculado a salud mental, solo tres consultaron por urgencias días antes de la precipitación y seis realizaron la tentativa en el contexto de servicios psiquiátricos. El diagnóstico más frecuente fue la paraplejía asociada a fracturas en las extremidades inferiores y traumatismos torácicos. Conclusiones. La precipitación por intento de autolisis provoca el 2% de las lesiones medulares, y la depresión y los trastornos psicóticos son las patologías psiquiátricas previas más prevalentes. Tras el período de rehabilitación, esta población requiere especial atención por parte de los equipos de salud mental, ya que combina factores de riesgo para cometer suicidio, como la historia de tentativas previas, y la presencia de una condición crónica discapacitante

Introduction. Studies published in other countries indicate that 1.6-3% of spinal cord injuries are acquired due to suicide attempt, the majority being produced by precipitation in patients with previous psychiatric disorders. Aims. To determine the frequency of attempted suicide as a cause of spinal cord injuries in a eurorehabilitation hospital and to describe the characteristics of these patients in psychiatric terms and functional disability. Patients and methods. Retrospective study in which all patients with spinal cord injuries due to suicide attempt in a period of 15 years in a neurorehabilitation hospital were reviewed. Results. Suicide attempt caused 2% (n = 61) of spinal cord injuries in our population. Although 93% of the patients were diagnosed with psychiatric pathology, 60% were linked to mental health facilities and only three consulted for emergency the days before the precipitation. Six attempts were made in the context of psychiatric services and 26% of patients had made previous attempts. The most frequent medical diagnosis was paraplegia associated with fractures in the lower extremities and chest trauma. Conclusions. Precipitation due to suicide attempt causes 2% of spinal cord injuries, with depression and psychotic disorders being the most prevalent psychiatric disorders. After the rehabilitation period, this population requires special attention from the mental health teams since they combine risk factors to commit suicide such as the history of previous attempts and the presence of a chronic disabling condition

Analgesic effect of intrathecal baclofen bolus on neuropathic pain in spinal cord injury patients.

BACKGROUND: GABA-ergic neurons are widely distributed throughout the central nervous system, including the spinal cord which is important for the transmission of pain impulses to the brain. Here we hypothesized that intrathecal baclofen (ITB) which is a GABA analogue might exert analgesic effects on neuropathic pain, which could be related to subtypes of pain in spinal cord injury (SCI). METHODS: SCI patients with a cervical or thoracic lesion and neuropathic pain were randomized to receive either a single ITB bolus or placebo. Numerical Rating Scale (NRS), Neuropathic Pain Symptom Inventory (NPSI), and Brief Pain Inventory (BPI) were obtained for assessment of neuropathic pain. Spasticity was assessed using Modified Ashworth Scale and visual analogue scale. Evaluations were performed at baseline, and 4, 8, and 24 h after application of ITB or placebo. RESULT: Eight patients received ITB, 5 placebo. Neuropathic pain improved significantly in the ITB group based on NRS, BPI, and NPSI, which revealed an effect on all subtypes of pain. Spasticity declined significantly. In the placebo group, there was neither significant change in pain nor in spasticity. CONCLUSION: An ITB bolus exerted a significant analgesic effect on all subtypes of neuropathic pain in SCI patients. SIGNIFICANCE: ITB has analgesic effects on all subtypes of neuropathic pain and can improve interference of neuropathic pain with activities of daily living. ITB might be a promising analgesic treatment to control neuropathic pain.

Optimizing the Management of Spasticity in People With Spinal Cord Damage: A Clinical Care Pathway for Assessment and Treatment Decision Making From the Ability Network, an International Initiative.

The recognition, evaluation, and management of disabling spasticity in persons with spinal cord damage (SCD) is a challenge for health care professionals, institutions, health systems, and patients. To guide the assessment and management of disabling spasticity in individuals with SCD, the Ability Network, an international panel of clinical experts, developed a clinical care pathway. The aim of this pathway is to facilitate treatment decisions that take into account the effect of disabling spasticity on health status, individual preferences and treatment goals, tolerance for adverse events, and burden on caregivers. The pathway emphasizes a patient-centered, individualized approach and the need for interdisciplinary coordination of care, patient involvement in goal setting, and the use of assessment and outcome measures that lend themselves to practical application in the clinic. The clinical care pathway is intended for use by health care professionals who provide care for persons with SCD and disabling spasticity in various settings. Barriers to optimal spasticity management in these people are also discussed. There is an urgent need for the clinical community to clarify and overcome barriers (knowledge-based, organizational, health system) to optimizing the management of spasticity in people with SCD.

Depression in Individuals With Traumatic and Nontraumatic Spinal Cord Injury Living in the Community.

OBJECTIVE: To assess depression in a sample of individuals with spinal cord injury (SCI) living in the community, and to determine the prevalence of probable major depressive disorder (PMDD) among those with traumatic spinal cord injury (T-SCI) and those with nontraumatic spinal cord injury (NT-SCI). DESIGN: Cross-sectional. SETTING: Data were collected on individuals with SCI now living in the community, who completed a comprehensive follow-up assessment at the hospital. PARTICIPANTS: Individuals with T-SCI or NT-SCI (N=831) completed the Patient Health Questionnaire-9 (PHQ-9) and were included. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The PHQ-9 was used to detect the presence of PMDD and to measure the severity of the depression. RESULTS: The most frequent etiology of SCI was T-SCI (66.9%). Overall, 16.2% of participants met the criteria for PMDD; however, a higher prevalence was noted for individuals with NT-SCI (21.1%) than for individuals with T-SCI (13.8%). Risk factors between T-SCI and NT-SCI did not differ greatly. Female sex, chronic pain, and lower levels of/difficulties in participation were associated with the presence of PMDD. CONCLUSIONS: PMDD appears to occur at a higher rate in individuals with NT-SCI, with greater symptom severity. The finding that problems with participation are directly associated with depression raises the need for specific treatment goals, with the aim of empowering individuals with SCI to reintegrate into the community. Potential stress factors (eg, environmental barriers, limited participation options) should be addressed accordingly.

Cost-effectiveness of Intrathecal Baclofen Therapy in severe refractory non-focal disabling spasticity: a Spanish hospital perspective.

BACKGROUND: Current knowledge about long-term economic consequences of Intrathecal Baclofen Therapy (ITB Therapy®) is incomplete. METHODS: A markov model was developed to estimate long-term clinical and economic outcomes with ITB Therapy® and conventional medical management of severe refractory non-focal disabling spasticity. Clinical and cost inputs were obtained through a non-interventional, prospective, observational study in a Spanish neurorehabilitation hospital. RESULTS: ITB Therapy® increased remaining lifetime costs by €35,605 and resulted in a gain of 1.06 quality-adjusted life-years (QALYs), thus showing an incremental cost-effectiveness ratio (ICER) of €33,619/QALY gained. In alternative scenarios, reflecting other clinical settings and management options, considerably lower ICER values were obtained. In particular, opportunities were identified to improve efficiency by setting clinically and economically sound targets for post-operation length of stay. CONCLUSION: In the Spanish setting, ITB Therapy® resulted in an ICER close to €30,000/QALY gained; potential ways to reduce costs and further enhance efficiency can be identified.

Effectiveness of Automated Locomotor Training in Patients with Acute Incomplete Spinal Cord Injury: A Randomized, Controlled, Multicenter Trial.

The aim of this study was to evaluate whether the effect of longer training times (50 instead of 25 min per day) using a robotic device results in a better outcome of walking ability of subjects with a subacute motor complete (American Spinal Injury Association Impairment Scale [AIS]-B) and incomplete (AIS-C) spinal cord injury. Twenty-one patients were enrolled in the study, whereof 18 completed, on average, 34 trainings in 8 weeks. Longer training times resulted in better locomotor function. The second important result of the study is that a beneficial effect can be achieved by the application of a robotic device for prolonged training sessions without requiring more personal resources. It has to remain open whether even longer training times (more than 50 min) would result in a still better outcome. In any case, the extent of possible recovery in an individual patient is determined by the level and severity of spinal cord damage.

Placebo-controlled study of rTMS combined with Lokomat® gait training for treatment in subjects with motor incomplete spinal cord injury.

High-frequency rTMS combined with gait training improves lower extremity motor score (LEMS) and gait velocity in SCI subjects who are able to walk over ground. The aim of this study was to optimize the functional outcome in early phases of gait rehabilitation in SCI using rTMS as an additional treatment to physical therapy. The present study included 31 motor incomplete SCI subjects randomized to receive real or sham rTMS, just before Lokomat gait training (15 subjects for real, 16 for sham rTMS). rTMS consisted of one daily session for 20 days over vertex (at 20 Hz). The subjects were evaluated using modified Ashworth scale (MAS) for spasticity, upper and lower extremity motor score (UEMS and LEMS, respectively), ten meters walking test (10MWT) and Walking Index for SCI (WISCI-II) for gait at baseline, after last rTMS session, and during follow-up. UEMS and LEMS improved significantly after last session in both groups and during follow-up period. The improvement was greater in real than in sham rTMS group. At follow-up, 71.4 % of the subjects after real rTMS and 40 % of the subjects after sham rTMS could perform 10MWT without significant differences in gait velocity, cadence, step length and WISCI-II between both groups. We conclude that 20 sessions of daily high-frequency rTMS combined with Lokomat gait training can lead to clinical improvement of gait in motor incomplete SCI. Such combined treatment improved motor strength in lower extremity in incomplete SCI subjects and in upper extremity in those with cervical SCI.

Transcranial direct current stimulation is not effective in the motor strength and gait recovery following motor incomplete spinal cord injury during Lokomat(®) gait training.

OBJECTIVE/HYPOTHESIS: Transcranial direct current stimulation (tDCS) is a potential tool to improve motor recovery in patients with neurological disorders. Safety and efficacy of this procedure for lower extremity motor strengthe and gait function in motor incomplete spinal cord injury (SCI) have not yet been addressed. The aim of this study is to optimize the functional outcome in early phases of gait rehabilitation assisted by Lokomat(®) in motor incomplete SCI patients using tDCS as an additional treatment to physical therapy. METHODS: We performed in a SCI unit a single-centre randomized, double-blind, sham-controlled study to investigate safety and efficacy of anodal tDCS of over leg motor cortex in motor incomplete SCI patients. Twenty-four SCI patients received either daily sessions of anodal tDCS (n=12) at 2mA for 20min to the vertex (leg motor cortex) during twenty days or sham tDCS (n=12). Motor deficit was assessed by the lower extremity motor score (LEMS) and for gait function: ten meter walking test (10MWT) and Walking Index for SCI (WISCI II) at baseline, after last tDCS session (after 4 weeks of stimulation), and after 8 weeks (from baseline) for follow-up. RESULTS: No side effects were detected during either tDCS or sham. In both groups, there was a significant improvement in LEMS (p<0.03), which did not significantly differ when comparing anodal and sham tDCS groups. During follow-up, in both group 5 of 12 patients could perform gait, without significant differences in gait velocity, cadence, step length and WISCI-II between both groups. CONCLUSION: Combination twenty sessions of daily tDCS to the leg motor cortex and Lokomat(®) gait training appear to be safe in motor incomplete SCI patients. There was an expected improvement in both LEMS and gait scales however, did not differ between patients treated with anodal or sham tDCS.

An international age- and gender-controlled model for the Spinal Cord Injury Ability Realization Measurement Index (SCI-ARMI).

Background. A quadratic formula of the Spinal Cord Injury Ability Realization Measurement Index (SCI-ARMI) has previously been published. This formula was based on a model of Spinal Cord Independence Measure (SCIM95), the 95th percentile of the SCIM III values, which correspond with the American Spinal Injury Association Motor Scores (AMS) of SCI patients. Objective. To further develop the original formula. Setting. Spinal cord injury centers from 6 countries and the Statistical Laboratory, Tel-Aviv University, Israel. Methods. SCIM95 of 661 SCI patients was modeled, using a quantile regression with or without adjustment for age and gender, to calculate SCI-ARMI values. SCI-ARMI gain during rehabilitation and its correlations were examined. Results. A new quadratic SCIM95 model was created. This resembled the previously published model, which yielded similar SCIM95 values in all the countries, after adjustment for age and gender. Without this adjustment, however, only 86% of the non-Israeli SCIM III observations were lower than those SCIM95 values (P < .0001). Adding the variables age and gender to the new model affected the SCIM95 value significantly (P < .04). Adding country information did not add a significant effect (P > .1). SCI-ARMI gain was positive (38.8 ± 22 points, P < .0001) and correlated weakly with admission age and AMS. Conclusions. The original quadratic SCI-ARMI formula is valid for an international population after adjustment for age and gender. The new formula considers more factors that affect functional ability following SCI.

Gait training in human spinal cord injury using electromechanical systems: effect of device type and patient characteristics.

OBJECTIVE: To report the clinical improvements in spinal cord injury (SCI) patients associated with intensive gait training using electromechanical systems according to patient characteristics. DESIGN: Prospective longitudinal study. SETTING: Inpatient SCI rehabilitation center. PARTICIPANTS: Adults with SCI (n=130). INTERVENTION: Patients received locomotor training with 2 different electromechanical devices, 5 days per week for 8 weeks. MAIN OUTCOME MEASURES: Lower-extremity motor score, Walking Index for Spinal Cord Injury, and 10-meter walking test data were collected at the baseline, midpoint, and end of the program. Patients were stratified according to the American Spinal Injury Association (ASIA) category, time since injury, and injury etiology. A subgroup of traumatic ASIA grade C and D patients were compared with data obtained from the European Multicenter Study about Human Spinal Cord Injury (EM-SCI). RESULTS: One hundred and five patients completed the program. Significant gains in lower-limb motor function and gait were observed for both types of electromechanical device systems, to a similar degree. The greatest rate of improvement was shown in the motor incomplete SCI patients, and for patients <6 months postinjury. The positive response associated with training was not affected by injury etiology, age, sex, or lesion level. The trajectory of improvement was significantly enhanced relative to patients receiving the conventional standard of care without electromechanical systems (EM-SCI). CONCLUSIONS: The use of electromechanical systems for intensive gait training in SCI is associated with a marked improvement in lower-limb motor function and gait across a diverse range of patients and is most evident in motor incomplete patients, and for patients who begin the regimen early in the recovery process.
