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.
