Effects of Walkasins on Gait Speed of Individuals With Mild Cognitive Impairments
A Pilot Study to Explore the Effects of Lower-Leg Mechanical Tactile Sensory Stimulation on the Gait Speed of Mildly Cognitively Impaired Individuals

Intervention / Treatment
Detailed Description
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 . . . 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.

Intervention / Treatment |
---|---|
Experimental: Walkasins and PhySens-IMM System--Single Arm
Participants who meet the eligibility criteria will don a pair of Walkasins and the PhySens-IMM System.
They will perform some brief balance exercises (i.e., sensory integration exercises) and then complete the outcome assessments with their Walkasins turned off and without the use of an assistive device.
After a rest period of about five minutes, they will repeat the outcome assessments with their Walkasins turned on.

Walkasins is a non-invasive, wearable, lower limb sensory prosthesis, prescribed by a healthcare professional for long-term daily use as a prosthesis. It directly replaces the part of the function of the sensory end organs that persons with peripheral neuropathy have lost, the sensation in the soles of their feet. The system is comprised of two primary operating components:

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in 4-Meter Gait Speed (Section 2 of the Short Physical Performance Battery)
Time Frame: 3 Times During 1 Session <1.5 Hours (Screening + Walkasins Off Condition then Walkasins On Condition)
|
The 4-meter gait speed test measures the number of seconds it takes a person to walk four meters on a level surface.
Gait speed measures are a significant indicator of a person's functional mobility.
Higher gait speeds (meters/second) are better than lower gait speeds and are indicative of better functional mobility.
(Generally, gait speeds less than 1m/second are considered slow.)

3 Times During 1 Session <1.5 Hours (Screening + Walkasins Off Condition then Walkasins On Condition)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Falls Efficacy Scale
Time Frame: Once During 1 Session <1.5 Hours
|
The Falls Efficacy Scale is a 16-item questionnaire that measures an individual's fear of falling or concerns about falling during activities of daily living.
Scores may range from 16 (not at all concerned) to 64 (very concerned).
Lower scores are better than higher scores because they indicate less concern about falling.
|
Once During 1 Session <1.5 Hours
|
Short Physical Performance Battery (SPPB)
Time Frame: Twice During 1 Session <1.5 Hours (Walkasins Off Condition then Walkasins On Condition)
|
The Short Physical Performance Battery measures walking speed, standing balance, and sit-to-stand performance.
Scores on balance, gait speed, and chair-stand tests are added (summed) for a total score.
(Scores on balance, gait speed, and chair-stand tests are not reported separately since they are not "subscales" per se.) SPPB scores may range from 0 to 12. Higher total scores indicate better balance and gait.
|
Twice During 1 Session <1.5 Hours (Walkasins Off Condition then Walkasins On Condition)
|
Timed Up and Go (TUG)
Time Frame: Twice During 1 Session <1.5 Hours (Walkasins Off Condition then Walkasins On Condition)
|
The Timed Up and Go Test is part of the Centers for Disease Control (CDC)-recommended STEADI test protocol for balance function.
From a seated position in a standard armchair, the participant is asked to stand up from the chair, walk to a line on the floor 10 feet away at normal pace, turn, walk back to the chair at normal pace, and sit down again.
The tester records the time taken from the command "Go" until the subject sits down again.
Lower times indicate better/faster performance.
|
Twice During 1 Session <1.5 Hours (Walkasins Off Condition then Walkasins On Condition)
|
Timed Up and Go Cognitive (TUG-COG)
Time Frame: Twice During 1 Session <1.5 Hours (Walkasins Off Condition then Walkasins On Condition)
|
The TUG-COG is performed similarly to the TUG; however, the participant is also asked to count backwards by 3 from a randomly selected number between 20 and 100 while performing the TUG (standing up from the chair, walking to a line on the floor 10 feet away, turning, walking back to the chair at a normal pace, and sitting down again).
Lower times indicate better/faster performance.
