Objective : To investigate the effectiveness of voluntary trunk rotation and half-field eye-patching to treat patients with unilateral neglect in stroke.

Design : Pre—post, day 60 follow-up, single-blinded randomized controlled trial.

Setting : Single-centre inpatient rehabilitation hospital.

Subjects : Sixty subacute patients with right hemisphere stroke having unilateral neglect within eight weeks post stroke consented to participate between November 2003 and July 2005. They were randomly assigned to three comparison groups.

Interventions : Nineteen patients received daily experimental training in voluntary trunk rotation (TR) for 1 hour five times a week for 30 days. Twenty patients received the same kind of treatment together with half-field eye-patching

(TR + EP). Fifteen patients in the control group received conventional training with the same contact time.

Main outcome measures : Patients were assessed on days 0, 30 and 60 using the Behavioural Inattention Test, the Clock Drawing Test, and the Functional Independence Measure.

Results : No significant differences between voluntary trunk rotation (TR), voluntary trunk rotation and half-field eye-patching (TR + EP) and controls were found in functional performance and neglect measures at day 30 (P = 0.042—0.994) and follow-up (P = 0.052—0.911) at P = 0.005 using Bonferroni correction.

Conclusions : The results of this study do not support the use of voluntary trunk rotation alone or with half-field eye-patching to improve functional performance or reduce unilateral neglect in subacute patients with stroke.
