Non-invasive Brain Stimulation to Improve Unsteady Gait in Older Adults (StimGait)
September 5, 2023 updated by: Hebrew SeniorLife
Modulating Brain Networks to Reduce Gait Variability in Older Adults at Risk of Falling
Walking is a complex and continuous task that entails repetitive motions of the body.
Relatively high gait variability sensitively predicts falls and cognitive decline in older adults.
Previous work has identified an unique brain network relationship linked to gait variability and its relevant cognitive function (i.e., sustained attention).
This project aims to develop a non-invasive brain stimulation montage designed to modulate the shared brain networks dynamics and to demonstrate its effects on resting state functional connectivity, gait and cognitive performance in older adults at risk for falls.

Conditions
Detailed Description
This is a randomized controlled trial to examine the efficacy of a non-invasive brain stimulation intervention of tDCS to improve unsteady gait in older adults.
The investigators will enroll 30 older adults with elevated gait variability.
Participants will be randomized into one of two arms: a) 10 sessions of tDCS and b) 5 sessions of sham stimulation followed by 5 sessions of tDCS.
Participants will engage in a set of pre-intervention assessments, the brain stimulation intervention - consisting of 10, once-daily, 20-min stimulation sessions over a 2-week period, and a set of post-intervention assessments.
This project is expected to demonstrate that tDCS can be used to reduce gait variability in older adults.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: tDCS intervention
Ten, once-daily, 20-min sessions of tDCS will be provided over two consecutive weeks.
|
The tDCS montage is developed to modulate the functional connectivity between the dorsal attention network and the default network.
|
Sham Comparator: Sham and then tDCS
Five, once-daily, 20-min sessions of sham in week one followed by five, once-daily, 20-min sessions of tDCS in week two.
|
The tDCS "Acti-" Sham montage is developed to recreate the cutaneous sensations associated with tDCS, yet essentially a null electrical field over the networks of interest.
The tDCS montage is developed to modulate the functional connectivity between the dorsal attention network and the default network.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Gait variability
Time Frame: Baseline, Immediate post-intervention, 1 month follow up
|
This measure is captured by both Mobility Lab (APDM Inc) and the smart phone App.
Gait variability is defined as the coefficient of variation to validated stride times.
|
Baseline, Immediate post-intervention, 1 month follow up
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Gait speed
Time Frame: Baseline, Immediate post-intervention, 1 month follow up
|
This measure is captured by Mobility Lab (APDM InC).
Gait speed id defined by the time one takes to walk a specified distance.
|
Baseline, Immediate post-intervention, 1 month follow up
|
Accuracy (d prime) on the gradual onset continuous performance task (gradCPT)
Time Frame: Baseline, Immediate post-intervention, 1 month follow up
|
The gradCPT is a computer-based cognitive task designed to measure sustained attention.
Accuracy (d prime) on the gradCPT can be derived from the gradCPT analysis tool box.
|
Baseline, Immediate post-intervention, 1 month follow up
|
Dual-task gait performance
Time Frame: Baseline, Immediate post-intervention, 1 month follow up
|
Participants will be asked to walk under two conditions: 1) walk at a comfortable, self-selected speed and 2) walk while counting backward by 1' or 3's from a random 3-digit number.
Dual-task gait characteristics will be captured while the participants concurrently walk and count.
We will further calculate the cost one takes to complete the dual-task walking from walking at a comfortable, self-selected speed.
