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.
