Quality of life and psychological outcomes of body-weight supported locomotor training in spinal cord injured persons with long-standing incomplete lesions.

STUDY DESIGN: Health-related quality of life (HRQOL) data from two parallel independent single-blinded controlled randomized studies of manual (Study 1) and robotic (Study 2) locomotor training were combined (ClinicalTrials.gov #NCT00854555). OBJECTIVE: To assess effects of body-weight supported locomotor training (BWSLT) programs on HRQOL in persons with long-standing motor incomplete spinal cord injury and poor walking function. SETTINGS: Two inpatient rehabilitation facilities and one outpatient clinic in Norway. METHODS: Data were merged into intervention (locomotor training 60 days) or control group ("usual care"). Participants completed questionnaires before randomization and 2-4 weeks after the study period, including demographic characteristics, HRQOL (36-Item Short-Form Health Status Survey, SF-36), physical activity (The International Physical Activity Questionnaire Short Form, IPAQ-SF), exercise barrier self-efficacy (EBSE), and motivation for training (Behavioral Regulation in Exercise Questionnaire, BREQ). Physical outcomes i.e., Lower extremity motor score (LEMS) was assessed. The main outcome was change in HRQOL. Secondary outcomes included changes in IPAQ-SF, EBSE, BREQ, and physical outcomes. RESULTS: We recruited 37 of 60 predetermined participants. They were autonomously motivated with high baseline physical activity. BWSLT with manual or robot assistance did not improve HRQOL, though LEMS increased in the BWSLT group compared with control group. CONCLUSIONS: The study was underpowered due to recruitment problems. The training programs seem to benefit LEMS, but not other physical outcomes, and had minimal effects on HRQOL, EBSE, and motivation. Autonomous motivation and high physical activity prior to the study possibly limited the attainable outcome benefits, in addition to limitations due to poor baseline physical function.

Robot-assisted locomotor training did not improve walking function in patients with chronic incomplete spinal cord injury: A randomized clinical trial.

OBJECTIVE: To assess the effects of robot-assisted locomotor training in patients with chronic incomplete spinal cord injury. DESIGN: Randomized single-blind controlled clinical trial. SETTING: The intervention site was an outpatient clinic, and pre- and post-evaluations were performed in a rehabilitation hospital. PATIENTS: A total of 24 subjects with American Spinal Injury Association Impairment Scale grades C or D, >?2 years post-injury. INTERVENTIONS: Subjects were randomized to 60 days of robot-assisted locomotor training, or to usual care. METHODS: Walking function, lower extremity muscle strength and balance were assessed single-blinded pre- and post-intervention. RESULTS: After a 9-year recruitment period, only 24 of the planned 30 subjects had been enrolled (mean time since injury 17 (standard deviation (SD) 20) years for all subjects). Walking function, lower extremity muscle strength and balance improved modestly in both groups, with no statistically significant group difference in walking function or muscle strength, whereas postural control declined significantly in the intervention group, compared with controls (p?=?0.03). CONCLUSION: Late-onset robot-assisted locomotor training did not re-establish independent walking function. A modest, but non-significant, effect was seen on muscle strength and balance. However, significant between-group differences were found only in postural control in the control group.

Manually assisted body-weight supported locomotor training does not re-establish walking in non-walking subjects with chronic incomplete spinal cord injury: A randomized clinical trial.

OBJECTIVE: To assess the effects of manually assisted body-weight supported locomotor training in subjects with chronic incomplete spinal cord injury. DESIGN: Randomized controlled clinical trial. SUBJECTS: Twenty subjects with American Spinal Injury Association Impairment Scale grades C or D and > 2 years post-injury. METHODS: Random allocation to 60 days of body-weight supported locomotor training, or usual care, which might include over-ground walking. Walking function, lower extremity muscle strength and balance were blindly evaluated pre-/post-intervention. RESULTS: A small, non-significant improvement in walking function was observed (0.1 m/s (95% confidence interval (95% CI) -0.2, 0.4)), but subjects without baseline gait function, did not re-establish walking. The effect on lower extremity muscle strength was 2.7 points (95% CI -1.4, 6.8). No difference was observed in balance measures. CONCLUSION: Subjects with chronic incomplete spinal cord injury without baseline walking function were unable to re-establish gait with manually assisted body-weight supported locomotor training. A modest, non-significant, improvement was found in strength and walking speed. However, due to study recruitment problems, an effect size that was smaller than anticipated, and large functional heterogeneity among study subjects, the effect of late-onset body-weight supported locomotor training is not clear. Future studies should include larger numbers of subjects with less functional loss and greater functional homogeneity. Intensive training should probably start earlier post-injury.

Cognitive Performance After a One-Year Multidisciplinary Intensive Rehabilitation Program for Huntington's Disease: An Observational Study.

BACKGROUND: Studies of physical therapy and multidisciplinary rehabilitation programs for Huntington's disease (HD) have shown improvements in gait function, balance, and physical quality of life. There is a gap in the literature on effects of cognitive interventions and the potential to improve cognitive performance. OBJECTIVE: To assess changes in cognitive performance among patients with early to middle stage HD as secondary analyses from a one-year multidisciplinary rehabilitation program. The program included cognitive stimulation as a non-specific cognitive intervention in addition to physical interventions. METHODS: A one-year rehabilitation program that included comprehensive neuropsychological assessments was completed by 31 out 37 participants with early to middle stages of HD. Socio-demographic and clinical information was recorded. A battery of neuropsychological tests was used to measure cognitive functions before and after the intervention. Descriptive statistics was used for sample characteristics. Paired sample t-tests and nonparametric Wilcoxon Signed ranked tests were used to compare cognitive measures at both time points. RESULTS: Scores on the Symbol Digit Modalities Test (SDMT) were significantly lower post intervention. There were no significant differences in all other measures. Scores on the Stroop color naming and California Verbal Learning Test-II (CVLT-II) long-term delayed recall tasks showed tendencies towards lower scores post intervention. CONCLUSIONS: An intensive multidisciplinary rehabilitation program for patients with HD was generally well tolerated and feasible, with no indication of negative effects on cognition. Neuropsychological measures overall remained stable following an intensive multidisciplinary rehabilitation program, however continued progression of cognitive impairment was evident on the SDMT, suggesting that disease progression is not halted. Randomized controlled trials are needed to verify these findings.

Effects of a Two-Year Intensive Multidisciplinary Rehabilitation Program for Patients with Huntington's Disease: a Prospective Intervention Study.

OBJECTIVE: To assess effects of a two year intensive, multidisciplinary rehabilitation program for patients with early- to mid-stage Huntington's disease. DESIGN: A prospective intervention study. SETTING: One inpatient rehabilitation center in Norway. SUBJECTS: 10 patients, with early- to mid-stage Huntington's disease. INTERVENTIONS: A two year rehabilitation program, consisting of six admissions of three weeks each, and two evaluation stays approximately three months after the third and sixth rehabilitation admission. The program focused on physical exercise, social activities, and group/teaching sessions. MAIN OUTCOME MEASURES: Standard measures for motor function, including gait and balance, cognitive function, including MMSE and UHDRS cognitive assessment, anxiety and depression, activities of daily living (ADL), health related quality of life (QoL) and Body Mass Index (BMI). RESULTS: Six out of ten patients completed the full program. Slight, but non-significant, decline was observed for gait and balance from baseline to the evaluation stay after two years. Non-significant improvements were observed in physical QoL, anxiety and depression, and BMI. ADL-function remained stable with no significant decline. None of the cognitive measures showed a significant decline. An analysis of individual cases revealed that four out of the six participants who completed the program sustained or improved their motor function, while motor function declined in two participants. All the six patients who completed the program reported improved or stable QoL throughout the study period. CONCLUSION: Our findings suggest that participation in an intensive rehabilitation program is well tolerated among motivated patients with early to mid-stage HD. The findings should be interpreted with caution due to the small sample size in this study.

Effects of a One Year Intensive Multidisciplinary Rehabilitation Program for Patients with Huntington's Disease: a Prospective Intervention Study.

OBJECTIVE: To assess the effects of an intensive, multidisciplinary rehabilitation program for patients with early to mid-stage Huntington's disease. DESIGN: A prospective intervention study. SETTING: Two Norwegian inpatient rehabilitation centers. SUBJECTS: 37 patients, with early- to midstage Huntington's disease Interventions: A one year rehabilitation program, consisting of three admissions of three weeks each, and a five-day evaluation stay approximately 3 months after the last rehabilitation admission. Focus was on physical exercise, social activities, and group/teaching sessions. There was also emphasis to implement of coordinated health care and social services for the patients. MAIN OUTCOME MEASURES: standard measures for motor function, including gait and balance, cognitive function, including MMSE and UHDRS cognitive assessment, anxiety and depression, activities of daily living (ADL), health related quality of life and Body Mass Index (BMI). RESULTS: Significant improvements were observed in gait function, balance, in physical quality of life, anxiety and depression, as well as in BMI. ADL-function remained stable with no significant decline. Only one cognitive measure (SDMT) showed significant decline, while no decline was observed for the remaining cognitive measures. CONCLUSION: A multidisciplinary intensive rehabilitation program in patients with early and mid stage HD is associated with improved balance, gait function, physical quality of life and with reduced depressive and anxiety symptoms. Longer follow-up is needed to assess if these positive effects are sustained. There should be emphasis to establishment of long term and coordinated health care services for the HD patient.
