The Walkasins system is one of a growing number of wearable devices that use various modalities of neuromodulation, defined as the alteration of nerve activity through targeted delivery of a stimulus, such as electrical stimulation or chemical agents, to specific neurological sites in the body (https://www.neuromodulation.com/). Because these technologies are relatively new, innovative applications of their use in various patient populations may lead to improvements in the care and quality of life of individuals who suffer from these life-altering diagnoses.~Previous studies of Walkasins have shown that individuals with peripheral neuropathy who have gait and balance problems walk faster with the Walkasins device. This increase may be related to an improved automaticity of gait function, which decreases the need for cognitive attention to the walking task, which is known to slow down gait. Individuals with mild cognitive impairment commonly show slow gait speeds, likely due to a decline in executive function. There is a reason to think that sensory stimuli from the Walkasins device can improve the automaticity of gait in these individuals and thereby enhance gait speed.
The primary aim of this pilot study is to investigate the effect of Walkasins, a wearable lower-limb sensory prosthesis, on the gait speed and balance function of participants with mild cognitive impairment as measured by the Saint Louis University Mental Status (SLUMS) Examination.
