Case study of patients participating in a randomised controlled trial of upper-limb robotic rehabilitation in acute stroke services

This paper presents some findings from a randomised controlled trial in patients with upper-limb weakness in acute stroke services within the UK's National Health Service. Three patients were selected from the robot arm of the trial; one who exhibited a large increase in Fugl-Meyer score (change > 30); one who exhibited a moderate change (10 <; change <; 20) and a subject who demonstrated no change between baseline and follow-up. The results from robot assistance level and target achievement over the course of the treatment are presented for the three patients, demonstrating the system's ability to automatically alter the assistance level as patients progress.
