Can Robotic Therapy Improve Performance in Activities of Daily Living? A Randomized Controlled Trial in Sub-Acute Spinal Cord Injured Patients

Abstract

(1) Background: The influence of robotic therapy on patients with sub-acute cervical spinal cord injury (SCI) for improving their activities of daily living (ADL) performance is unclear; (2) Methods: 31 subjects with cervical SCI completed the training randomly assigned to an intervention or control group during 40 sessions. All the subjects received, in each session, 30 min of upper-extremity conventional therapy. In addition, the subjects within the control group received another 30 min of conventional therapy, whereas subjects within the intervention group received 30 min of robotic therapy with Armeo Spring (Hocoma AG, Volketswil, Switzerland). Therefore, the ADL of drinking was trained by using the exoskeleton. Feasibility and efficacy measurements as clinical scales and kinematic indices, and usability questionnaires, were used as assessment at baseline and at the ending of the study (week 10); (3) Results: The intervention group significantly improved with regards to the feeding and grooming items of the Spinal Cord Independence Measure scale. The improvement in the movement smoothness related to the activity of drinking was greater in the intervention group than in the control (p = 0.034); (4) Conclusions: The findings of this study reveal that patients with cervical SCI improve their performance in ADL with robotic therapy.
