Transcutaneous Stimulation for Neurological Populations
Study Details
Study Description
Brief Summary
The purpose of the study is to evaluate whether non-invasive stimulation over the spinal cord at the neck and/or lower back can improve walking function for people with neurologic conditions. Spinal stimulation has been used extensively for individuals with spinal cord injury, and has demonstrated improvements in function. This study will extend this work to other neurologic conditions, such as cerebral palsy and stroke, that also demonstrate similar impairments as spinal cord injury.
The primary aims of this study are to:
Aim 1: Evaluate impact of spinal stimulation on spasticity and locomotor function.
Aim 2: Investigate participant perceptions of spinal stimulation.
The investigators will be using a cross-over design study to compare intensive training only to intensive training combined with spinal stimulation. After an initial baseline period of up to 4 weeks (Phase I). Participants will have their first intervention phase of the study (Phase II). This will involve either intensive training only (Condition A) or intensive training combined with spinal stimulation (Condition B). This will be followed by a washout period with no intervention (Phase III) and then the second intervention phase (Phase IV). The second intervention phase will involve either Condition A or Condition B, whichever the participants did not received during Phase II. Phases II-IV will each last up to 8 weeks. After the intervention period is complete, the participant will be asked to come for follow-up visits up to 3 months after the intervention phases are completed (Phase V).

Outcome Measures
Primary Outcome Measures
- Six-Minute Walk Test (6MWT) [8-11 months]
Measure of walking ability. The distance is reported in meters.
- Ten-Meter Walk Test (10MWT) [8-11 months]
Measure of walking ability at fast and self-selected speeds. The walking speed is reported as meters per second
Secondary Outcome Measures
- Kinetic and kinematic gait analysis using 3D camera system [8-11 months]
Measurement of leg function and walking ability. Joint angle is reported in angle degrees, and velocity is reported in meters per second. Kinematic analysis will able to used to measure gait coordination and spatiotemporal outcomes, such as step length and step time.
- Electromyography recording of lower extremity muscles [8-11 months]
Measurement of muscle and nerve functions. The muscle activities are reported in micro-volts.
- Gait Outcomes Assessment List (GOAL) [8-11 months]
Patient reported outcome measure for ambulatory children with cerebral palsy. The GOAL comprises of 48 items distributed across 7 subscales, and spans all domains of the International Classification of Functioning, Disability and Health (ICF).
- Timed Up and Go (TUG) [8-11 months]
Measurement of mobility and fall risk. The time to complete the test is recorded in seconds.
- Modified Ashworth and Tardieu Scales [8-11 months]
Measurement of spasticity in muscles.
- PROMIS Pediatric-49 Profile v2.0 [8-11 months]
Includes six PROMIS domains (Depressive Symptoms, Anxiety, Physical Function-Mobility, Pain Contains 8 items on each of the 6 domains: Interference, Fatigue, and Peer Relationships) along with a single item on Pain Intensity.
