The Effects of Robot-Assisted Therapy on Upper Extremity Functions and Functional Independence in Geriatric Individuals With Chronic Stroke: A Randomized Controlled Study

Abstract

Aim

Stroke often leads to impaired motor functions, particularly in upper extremities, making functional recovery essential for quality of life and independence. This study aims to examine effects of robot-assisted therapy on upper extremity functions and activities of daily living in rehabilitation of geriatric patients with chronic stroke.

Methods

Geriatric participants who had a stroke at least six months prior were randomly assigned to either an intervention group receiving both conventional physiotherapy and robot-assisted therapy (ReoGo end-effector robotic system) or a control group with conventional physiotherapy only. Intervention group participated in 60-min ReoGo sessions along with daily physiotherapy over four weeks. Fugl-Meyer Upper Extremity Assessment Scale and Functional Independence Measure evaluated motor functions and daily living independence, respectively. Pre- and post-treatment results were statistically analyzed within and between groups.

Results

Among the 30 participants, those in intervention group showed significantly greater improvements in upper extremity functions and daily living independence compared to the control group (p < .05). While control group exhibited minor improvements, these changes were not statistically significant, underscoring the greater efficacy of combined approach.

Discussion

Robot-assisted therapy significantly enhances motor recovery, likely due to its support for neuroplasticity through repetitive, controlled movements. This aligns with existing research, emphasizing benefits of robot-assisted therapy for motor learning and functional gains. ReoGo device also positively affected motivation and engagement, highlighting its potential role in long-term stroke rehabilitation. Overall, robot-assisted therapy may be a promising approach to improve motor recovery and independence in post-stroke patients, enhancing both quality of life and functional independence in daily activities.
