Background: Fatigue is common after chronic stroke, which may cause upper extremity sensory-motor dysfunction, as well as decreased independence in activities of daily living (ADLs) and participation. This study aimed to investigate the effects of upper extremity exercises based on fatigue prediction on sensory-motor functions and ADLs in subjects with chronic stroke.
Methods: This is a pilot study. Twenty subjects with chronic stroke (11 male and 9 female) with mean age of 56±14.09 years and mean time since the stroke of 71.05±53.5 months were randomly assigned to either the control group (receiving conventional rehabilitation) or intervention group (receiving unimanual exercises based on fatigue prediction) using the Kinect Upper extremity motor function. Fine and gross manual dexterity, grip strength, shoulder and elbow proprioception, independence in ADLs, participation, and fatigue severity were assessed before the interventions, after the interventions (6 week, each weak 3 session, for 45 minute) and 6 weeks following the completion of the interventions (i.e. follow up).
Result: In both control and intervention groups, a significant improvement was observed in all assessments (P≤0.05), except for independence in ADLs. Moreover, the decrease in fatigue severity and improvement in fine manual dexterity was significantly greater in the intervention group compared with the control group (P≤0.05).
Conclusion: The results of this study indicated that upper extremity exercises based on fatigue prediction led to an improvement in upper extremity sensory-motor functions, manual dexterity, and participation as well as a decrease in fatigue severity in subjects with chronic stroke.
