- Conditions
- Cerebral Palsy Spastic Diplegia
- Interventions
- Device: FESOther: Cycling
- Registration Number
- NCT04688424
- Lead Sponsor
- Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)
- Brief Summary
This project proposes to assess if Functional Electrical Stimulation (FES) assisted cycling can improve the cycling ability, muscle strength, cardiovascular health, quality of life, self perception and functional mobility of adolescents with CP better than a volitional cycling program or a non-intervention control group.
- Detailed Description
Aim 1: To compare the effects of 8-weeks of FES-assisted cycling training on improving cardiorespiratory fitness, walking function, self-motivated exercise/recreation, self-perception and functional mobility and quality of life of adolescents with spastic CP with marginal walking ability (Gross Motor Function Classification System Levels II - IV) vs. 8-weeks of volitional cycling training and a non-intervention control group.
Aim 2: To compare the effects of 8-weeks FES-assisted cycling training on changes in cycling ability of adolescents with spastic CP with marginal walking ability vs. 8-weeks of volitional cycling training and a nonintervention control group.
Aim 3: To elucidate the mechanisms for potential improvements in cycling ability after 8-weeks of FES-assisted or volitional cycling training of adolescents with spastic CP and marginal walking ability.

- Primary Outcome Measures
Name Time Method Change in cycling Ability Outcome assessed: Pre Training (week 0), Mid Training (week 4), Post Training (week 8), Follow-Up (week 16) Change in cycling cadence from pre-training to post-training and at follow-up will be assessed.
Change in Energy Expenditure Outcome assessed: Pre Training (week 0), Mid Training (week 4), Post Training (week 8), Follow-Up (week 16) Energy expenditure is a measure of cardiovascular fitness. Change in energy expenditure from pre-training to post-training and at follow-up will be assessed.
Change in Gait speed Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) Gait speed will be measured using a GAITRite Portable Walkway System (CIR Systems Inc; Havertown, PA). We will measure the change in gait speed from pre-training to post-training and at follow-up.
Change in Spatiotemporal gait parameter Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) Step length will be measured using a GAITRite Portable Walkway System (CIR Systems Inc; Havertown, PA). We will measure the change in step length from pre-training to post-training and at follow-up.
Change in Muscle Strength Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) Isometric maximum voluntary exertion testing of hip extensors \& flexors, knee extensors \& flexors, and ankle plantarflexors. We will measure the change in isometric maximum voluntary exertion from pre-training to post-training and at follow-up.
Change in Walking Distance Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) 6 minute walk test (6MWT) measures walking distance. Walking distance (in a fixed period of time) is an indicator of endurance. We will measure the change in walking distance from pre-training to post-training and at follow-up.
Change in Timed Up-And-Go Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) Timed Up-And-Go (TUG) is a measure of functional mobility and will allow for assessing the impact of anticipated improvements in motor control and gait biomechanics. We will measure the change in TUG test from pre-training to post-training and at follow-up.
Change in Pedometer measurement Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) Pedometer measurements to allow an unbiased report of the subject's activity level at home and in the community. We will measure the change in pedometer measurements from pre-training to post-training and at follow-up.
Change in Electromyography Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) Muscle activation timing measured with electromyography (EMG) during analysis allows for mechanistic study of anticipated improvements in motor control as well as comparison to typical norms. We will measure the change in EMG from pre-training to post-training and at follow-up.
Change in Self-Assessment Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) Canadian Occupational Performance Measure (COPM) is a 10 point scale to rate one's own level of performance and satisfaction with performance. 1 mean poor performance low satisfaction and 10 means very good performance high satisfaction. We will measure the change in COPM scores from pre-training to post-training and at follow-up.
Change in Health related Quality of Life Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) The KINDL questionnaire is administered to measure changes in health-related quality of life. The questionnaire is completed by the adolescent and a caregiver. The KINDL standard scale and "Disease Module" is administered. The standard scale contains 24 items comprised of Physical, Emotional, Self-Esteem, Family, Friends and School sub-scales. The 6-item "Disease Module" that measures the child's and caregiver's perceptions about CP. Scores for each item ranges from 1-5. The total score is the sum of all item scores, transformed to a 0-100 scale. Higher scores indicate better quality of life. We will measure the change in KINDL scores from pre-training to post-training and at follow-up.
Change in Self-Perception Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16) Self-Perception (Piers-Harris-2) survey measures physical and emotional well-being and self-esteem and will allow assessment of the impact of anticipated improvements in motor control and gait biomechanics from training. We will measure the change in Piers-Harris scores from pre-training to post-training and at follow-up.
