Refinement and Clinical Evaluation of the H-Man for Arm Rehabilitation After Stroke

Stroke Clinical Trial

Official title: Refinement and Clinical Evaluation of the H-Man: A Novel, Portable, Inexpensive Planar Robot for Arm Rehabilitation After Stroke

Status Completed

Clinical Trial Summary

Locally, stroke remains the 4th cause of death, causing 8.4% of deaths annually in Singapore, and a leading cause of neurological disability worldwide. Nearly 40% of the stroke survivors will require specialized rehabilitation. In recent years, robot-aided therapy has been proposed as a means of complementing traditional therapy to alleviate the burden on therapists and on the healthcare system. For shoulder/elbow rehabilitation, dozens of robots have been proposed in the literature but only half a dozen have been commercialized and typically none are seen in local clinics, due to exceedingly high costs. A novel, compact, inexpensive robotic interface, named 'H-Man', was recently designed and developed at NTU for experiments in motor control neuroscience. The H-man can generate computer-controlled force fields to assist or resist a subject's motion and is potentially an optimal trade-off between clinical efficacy and robotic complexity. A first prototype of the H-Man is available at NTU.The primary aim of this proposed project is to assess to what extent the investigators H-Man is suitable for rehabilitation purposes using a feasibility pilot clinical trial design involving stroke survivors. The investigators believe that H-Man can be used for neuro-rehabilitation of stroke patients with hemiparetic weakness, motor incoordination and motor ataxia of the upper limbs.In close cooperation between clinicians at the TTSH and NTU engineers, a portable version of the H-Man will be developed which will be tested in a 12 subject Pilot study, refined and then used in a 44 subject Randomized Controlled Trial (RCT) study. At the same time, the feasibility of H-Man integration for a pared down home use model will be assessed in 4 subjects.

The investigators primary hypothesis is that sub-acute/chronic patients will exhibit clinically significant decreases of impairment when training with the H-Man combined with standard arm therapy on robot-measured scales and standardized clinical scales, at the level of elbow/shoulder after 18 sessions of training on the H-Man.
