Rhythmic Haptic Cueing for Entrainment: Assisting Post-stroke Gait Rehabilitation

Abstract

Abstract:Restoring mobility and rehabilitation of gait are high priorities for rehabilitation from neurological conditions. Cueing using metronomic rhythmic sensory stimulation via entrainment has been shown to improve gait, but almost all previous versions of this approach have used auditory or visual cues. In contrast, we have developed and pilot-tested a prototype wearable system for rhythmic cueing based on haptics. Our initial pilot study indicated the same kinds of improvement to gait with haptics as for other cueing modalities, but haptics offer some advantages over audio and visual cues. In particular, haptics are generally more practical for use out of doors, in noisy environments, or when wishing to keep open the ability to converse freely. However, haptics also allow the precisely targeted spatial placement of cues on alternate limbs, offering the ability to manipulate attention and proprioception for therapeutic benefit. We outline the theory behind our approach and report on the iterative design of the system as part of a user-centred design evaluation process involving a wide range of stakeholders.

Questioning Classic Patient Classification Techniques in Gait Rehabilitation: Insights from Wearable Haptic Technology

“…A previous paper [8] considered data from questionnaires, interviews, and from dialogues between stroke survivors, health professionals and interaction designers that were carried out during sessions. In this paper we consider the issues and questions raised in the context of the analysis of the motion capture data.…”
