Hypoesthesia Clinical Trial
Official title:
Multimodal Haptic Feedback for Plantar Sensory Substitution
The study will explore the use of a haptic device for sensory substitution in individuals with a movement disorder that has caused loss of plantar sensation. The haptic device consists of two components. The first element is a flexible insole with embedded pressure-sensing elements that transmit the spatial patterns of applied foot pressure over time. The second element is a haptic receiver with embedded actuators that vibrate or heat up in proportion to the transmitted pressure patterns, thus substituting the patient's lost plantar sensation.
OBJECTIVES: 1. Identify a systematic, methodical approach to determine whether different users of our haptic device can perceive and use vibrational and thermal feedback in order to correct their posture in real-time. 2. Evaluate whether a haptic device can be used to guide users to maintain a prescribed pattern of pressure on their feet during standing and walking. 3. Investigate whether a haptic device can improve outcomes on motor evaluation tasks. ;
