Effects of modified constraint-induced movement therapy with trunk restraint in early stroke patients: A single-blinded, randomized, controlled, pilot trial.

BACKGROUND

Reducing compensatory strategies during repetitive upper-limb training may be helpful in relearning motor skills.

OBJECTIVE

To explore the effects of modified constraint-induced movement therapy (mCIMT), additionally modified by adding trunk restraint (TR), on upper-limb function and activities of daily living (ADLs) in early post-stroke patients.

METHODS

Twenty-four participants with early stroke were randomly assigned to mCIMT combined with TR (mCIMT + TR) or mCIMT alone. Each group underwent twenty sessions (1 h/d, 5 d/wk for 4 weeks). Patients were assessed with the action research arm test (ARAT), the Fugl-Meyer Assessment-Upper extremity (FMA-UE), the Modified Barthel index (MBI), the Maximal elbow extension angle during reaching (MEEAR), and Motor Activity Logs (MAL-AOU and MAL-QOM).

RESULTS

The mCIMT + TR group exhibited greater improvement in the ARAT, FMA-UE, MBI, MEEAR, and MAL-AOU, and MAL-QOM than the mCIMT group. Statistical analyses showed significant differences in ARAT (P = 0.003), FMA-UE (P = 0.042), MBI (P = 0.001), MEEAR (P = 0.002), and MAL-AOU (P = 0.005) between the groups.

CONCLUSION

Modified CIMT combined with TR may be more effective than mCIMT alone in improving upper-limb function and ADLs in patients with early stroke.
