Exo-rehabilitation of patients with spastic hemiparesis: high technology

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).
