Hand Orthosis for Stroke Rehabilitation

Rehabilitating the hand is, in a sense, the neglected middle child of stroke recovery. Rehabilitation therapies (physical, occupational and speech) are proven methods, but also a precious resource. Occupational therapy (that would include but not be exclusively devoted to the hand) is typically only provided up to a maximum of 3 hours per week for six months or less, and little improvement is generally seen after that. In fact, fewer than half of stroke patients with upper limb impairment ever regain functional use! And, as one stroke patient concluded in personal discussions, "if the hand does not work, there is little incentive to use the arm at all..."

We aim to develop a wearable and active hand orthosis able to assist the user in creating hand movement and applying forces. During the post-event recovery period, this device will serve as a rehabilitation tool; both during recover and thereafter, it can also serve as a functional device worn for performing daily activities. Critically, if an orthosis can be wearable, dexterous and intuitive to use, patients could use it outside of direct clinical supervision, including at home.
