About

This is a single-blinded randomized controlled trial to investigate the effects of mirror therapy (MT), with reference to sham mirror (a glass wall) and control (a covered mirror), in reducing unilateral neglect for patients with stroke in 2 centres.

Full description

Twenty-one subacute inpatients with left unilateral neglect after right-hemispheric stroke, recruited from 2 hospitals - Hong Kong and Guangzhou, in 1 and a half years, were randomly assigned to three groups; mirror therapy, sham therapy (in the form of a transparent glass wall), and control (covered mirror). The treatment programme for all groups consisted of 12 sessions (4 per week for 3 weeks) movement practice for the hemiplegic arm involved 5 table-top tasks graded according to the severity of patients' arm impairments. Blinded assessments were administered at baseline, 3-week postintervention, and 3-week follow-up upon completion of training.
