Computer-enhanced mental practice in upper-limb rehabilitation after cerebrovascular accident: a case series study

We examined the potential of using computer-enhanced mental practice in the rehabilitation of upper-extremity function after cerebrovascular accident (CVA). Design: Single case series, before-after design (ABA). Participants: 9 adults with stable motor deficit of the upper extremity following CVA. Methods: Patients received three computer-enhanced motor imagery practice sessions per week at the rehabilitation center. In addition, they practiced at home with specific exercises recorded on a DVD. The intervention lasted 8 weeks. Baseline, mid-term, post-intervention and follow-up evaluations included the upper-extremity scale of the Fugl-Meyer Assessment of Sensorimotor Impairment and the Action Research Arm Test. Results. At 8 weeks from the beginning of treatment, five patients showed reduction in impairment, with no decrease of motor function to follow up, as indicated by functional assessment scores and physiatrist observations. Conclusion: current findings encourage further investigation of the role that computer-guided motor imagery practice might play in upper limb rehabilitation.
