Exo-rehabilitation of patients with spastic hemiparesis: high technology

Abstract

AIM: Walking disorders are a frequent consequence of stroke. New technologies, such as the use of robotic exoskeletons, can help with recovery, but their effectiveness has not yet been sufficiently proven. MATERIALS AND METHODS: Forty-two patients with spasticity and walking disorders (stroke duration from 1.5 to 4 years) were included in the study. The Tardieu Scale, Modified Ashworth scale, Medical Research Council Scale, 10 Meter Walk Test, Rivermead Mobility Index, Berg Balance Test, Rankin scale, and a Visual Analog Scale (to assess patient satisfaction with treatment) were used in assessments. The patients were randomized into 2 groups (n = 22 20): the first group received exoskeleton walk training with the powered exoskeleton, ExoAtlet, and the second group received physical therapy sessions, each for 1 hour daily over 10 days. Clinical evaluations of patients were performed at 3 timepoints: baseline (Day 1), and 12. RESULTS: Comparison of both groups at the second timepoint showed significantly better results (p 0.05) in the first group vs the second group. Walking speed increased due to balance training, correction of postural disorders, spastic muscle stretching, and stretch reflex suppression. CONCLUSION: The wearable powered ExoAtlet exoskeleton is a promising technology for improving walking (2 tables, bibliography: 13 refs).
