About this trial
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.

Treatments tested in this trial
Haptic Device
DeviceProvides sensory substitution by mapping pressure from the insole sensor onto a corresponding vibrating and heating patch to be worn where more sensation is present.

Trial outcomes
Primary outcomes
1
Pressure data from the insoles
The primary outcome is to use the pressure-sensitive insole to ensure that we can accurately record spatial and temporal pressure data from a wide variety of healthy and non-healthy individuals.
