Does the use of Nintendo Wii Sports improve arm function? Trial of Wii in Stroke: a randomized controlled trial and economics analysis.

Objective: The Trial of Wii™ in Stroke investigated the efficacy of using the Nintendo Wii Sports™ (Wii) to improve affected arm function after stroke.

Design: Multicentre, pragmatic, parallel group, randomized controlled trial.

Setting: Home-based rehabilitation.

Does the use of Nintendo Wii Sports™ improve arm function and is it acceptable to patients after stroke? Publication of the Protocol of the Trial of Wii™ in Stroke - TWIST.

Introduction: Many stroke patients experience loss of arm function requiring rehabilitation, which is expensive, repetitive, and does not always translate into "real life." Nintendo Wii Sports™ (Wii™) may offer task-specific training that is repetitive and motivating. The Trial of Wii™ in Stroke (TWIST) is designed to investigate feasibility, efficacy, and acceptability using Wii™ to improve affected arm function for patients after stroke.
