About this trial

The primary objective of this new line of research is to test whether augmenting sensory information from the legs, using Walkasins sensory neuroprosthesis, can enhance performance of a complex walking task in older adults with foot sensory impairment. The overarching hypothesis is that Walkasins will enhance the automaticity and reduce cognitive demand of walking in older adults with foot sensory impairments, as measured by reduced prefrontal activity, decreased dual-task costs, and lower gait variability.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Not having any significant existing medical conditions, historical health issues, or medications (outlined in the

Disqualifiers

age 65 - 95.

no severe high blood pressure (systolic < 180 mmHg and/or diastolic < 100 mmHg at rest).

Trial design

Design model

Crossover

Treatments tested in this trial

  • Active lower-limb neuroprosthesis

    Device

    Walkasins sensory neuroprosthesis provides real-time sensory input by delivering vibrotactile stimuli to the lower limbs above the ankle

  • Inactive lower-limb neuroprosthesis

    Device

    Walkasins sensory neuroprosthesis does not provide real-time sensory input by delivering vibrotactile stimuli to the lower limbs above the ankle

Treatment groups

30 Participants
are divided into 2 treatment groups
Group A: Active lower-limb neuroprosthesisActive comparator 1 intervention
Group B: Inactive lower-limb neuroprosthesisSham comparator 1 intervention
