ABSTRACT

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.

ABSTRACT

STUDY DESIGN: Retrospective study. OBJECTIVE: To analyse the orthotic walking outcome of patients with Low Thoracic Spinal Cord Injury (LT-SCI). SETTING: The Rehabilitation Institute at Christian Medical College, Vellore, India. METHODS: Data between January 2005 and June 2015 were retrospectively collected from electronic medical reports of patients with motor complete LT- SCI who were admitted for the comprehensive rehabilitation program. The orthotic walking outcome of these patients was measured by the Walking index for SCI version II (WISCI II). Demographical and clinical parameters were measured and their association with the walking outcome was analyzed using regression analysis. RESULTS: A total of 430 patients were identified within the study period. Eighty-five percent of people (n = 365) achieved walking at the time of discharge (WISCI II level 12 = 260 and level 9 = 105). Out of 11 demographical and clinical parameters considered, eight of them were found to be significant predictors of walking in the univariate analysis. Age less than 30 years had the highest odds of predicting WISCI II level 9 and level 12 than those older in the multivariate analysis (OR 17.58; 95% CI 7.35-42.03). Single neurological level T12 increased the chance of achieving WISCI II level 12 by 10 times (OR 10.2; 95% CI 3.8-27.36). CONCLUSIONS: Orthotic walking for persons with motor complete low thoracic spinal cord injury is an achievable goal through a comprehensive rehabilitation program. The factors identified in this study will help rehabilitation professionals strategically select the ideal candidate for orthotic gait training.
