Constraint Induced Movement Therapy and Bilateral Training in Chronic Stroke

Stroke is a leading cause of long-term disability, with upper limb spasticity and impaired hand function being common problems in the chronic phase. These impairments significantly affect independence in activities of daily living and overall quality of life. Constraint-Induced Movement Therapy (CIMT) and Bilateral Training (BT) are two widely used neurorehabilitation approaches aimed at improving upper limb motor recovery after stroke; however, evidence comparing their effectiveness on wrist spasticity and hand function in chronic stroke patients remains limited. This single-blinded randomized controlled trial aims to compare the effects of Constraint-Induced Movement Therapy combined with Functional Electrical Stimulation (FES) versus Bilateral Training combined with Functional Electrical Stimulation on wrist spasticity and hand function in patients with chronic stroke. A total of 94 participants diagnosed with chronic stroke will be randomly allocated into two groups. Group A will receive CIMT with FES, while Group B will receive Bilateral Training with FES. Both interventions will be administered three times per week for eight weeks. Outcome measures will include wrist spasticity assessed using the Modified Ashworth Scale (MAS) and upper limb motor function assessed using the Fugl-Meyer Assessment for Upper Extremity (FMA-UE) and the Chedoke Arm and Hand Activity Inventory (CAHAI). Assessments will be conducted at baseline and after completion of the intervention period. The findings of this study are expected to provide evidence on the comparative effectiveness of CIMT and Bilateral Training in improving wrist spasticity and hand function, thereby assisting clinicians in selecting optimal rehabilitation strategies for chronic stroke patients.
