Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The overall goal of this research is to use ischemic conditioning to enhance muscle power, motor leaning, and mobility in children with CP. Our previous work demonstrated that when paired with strength training, RLIC improved muscle strength and activation in healthy, young adults and motor learning in healthy older adults. The current study extends that work to determine if RLIC enhances muscle power, dynamic balance, and walking performance in children with CP. This Phase II study will yield the necessary information to design and execute subsequent randomized controlled trials in children with CP as well as other neurological conditions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Remote Limb Ischemic Conditioning (RLIC)
RLIC is achieved via blood pressure cuff inflation to at least 20 mmHg above systolic blood pressure to 200 mmHg on the more involved thigh. RLIC involves 5 cycles of 5 minutes blood pressure cuff inflation followed by alternating 5 minutes of cuff deflation and requires 45 minutes. RLIC is performed on visits 1-14.
Interventions:
* Behavioral: RLIC
* Behavioral: Muscle power training
* Behavioral: Balance training
* Behavioral: Treadmill training
RLIC
See descriptions under arm/group descriptions. RLIC is delivered for 14 visits. Visits 1-3 occur on consecutive work days and visits 4-14 occur on alternating week days.
Muscle Power training
All participants undergo power training of the quadriceps muscles using unilateral and bilateral leg presses (Total Gym GTS, San Diego, CA), 3 times/week for 4 consecutive weeks (12 sessions). Power training will follow standard American College of Sports Medicine guidelines for frequency, intensity, progression etc. Power training is provided at visits 3-14.
Balance training
All participants undergo training on a balance board, learning to hold the board level with equal weight on each leg. Participants perform the balance task for 15, 30-second trials per day at visits 3-14.
Treadmill Training
All participants will undergo short burst interval treadmill training using self-selected and fast walking speeds.
Sham Conditioning
Sham conditioning is achieved via blood pressure cuff inflation to 25 mmHg on the more involved thigh. Sham involves 5 cycles of 5 minutes blood pressure cuff inflation followed by alternating 5 minutes of cuff deflation and requires 45 minutes. Sham conditioning is performed on visits 1-14.
Interventions:
* Behavioral: RLIC
* Behavioral: Muscle power training
* Behavioral: Balance training
* Behavioral: Treadmill training
