This comparative efficacy study will be the first to examine and compare the immediate and long-term combination effects of BoNT injection with RT, MT, or CI. The follow-up assessments will provide the long-term effects of different treatments on health-related outcomes, which are crucial for community reentry. In addition, the results of objective assessments and patient-reported outcomes may lead to individualized upper limb training following BoNT-A injection for patients with spastic hemiplegic stroke.
