Passive rehabilitation devices, providing motivation and feedback,
potentially offer an automated and low-cost therapy method, and can be
used as simple human–machine interfaces. Here, we ask whether there is any
advantage for a hand-training device to be elastic, as opposed to rigid,
in terms of performance and preference. To address this question, we have
developed a highly sensitive and portable digital handgrip, promoting
independent and repetitive rehabilitation of grasp function based around a
novel elastic force and position sensing structure. A usability study was
performed on 66 healthy subjects to assess the effect of elastic versus
rigid handgrip control during various visuomotor tracking tasks. The
results indicate that, for tasks relying either on feedforward or on
feedback control, novice users perform significantly better with the
elastic handgrip, compared with the rigid equivalent (11% relative
improvement, 9–14% mean range; p < 0.01). Furthermore, there was a
threefold increase in the number of subjects who preferred elastic
compared with rigid handgrip interaction. Our results suggest that device
compliance is an important design consideration for grip training devices.
