Background: This study examined the efficacy of a home-based Constraint Induced Movement Therapy (CI Therapy) protocol with eight poststroke survivors.

Method: Eight ABA, single case experiments were conducted in the homes of poststroke survivors. The intervention comprised restraint of the intact upper limb in a mitt for 21 days combined with a home-based and self-directed daily activity regime. Motor changes were measured using The Wolf Motor Function Test (WMFT) and the Motor Activity Log (MAL).

Results: Grouped results showed statistically and clinically significant differences on the WMFT (WMFT [timed items]): Mean 7.28 seconds, SEM 1.41, 95% CI 4.40 – 10.18, p = 0.000; WMFT (Functional Ability): z = -4.63, p = 0.000). Seven out of the eight participants exceeded the minimal detectable change on both subscales of the MAL.

Conclusion: This study offers positive preliminary data regarding the feasibility of a home-based CI Therapy protocol. This requires further study through an appropriately powered control trial.
