Outcome Measures

Primary Outcomes (12)

  • Change in cycling Ability

    Change in cycling cadence from pre-training to post-training and at follow-up will be assessed.

    Outcome assessed: Pre Training (week 0), Mid Training (week 4), Post Training (week 8), Follow-Up (week 16)

  • Change in Energy Expenditure

    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.

    Outcome assessed: Pre Training (week 0), Mid Training (week 4), Post Training (week 8), Follow-Up (week 16)

  • Change in Gait speed

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Spatiotemporal gait parameter

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Muscle Strength

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Walking Distance

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Timed Up-And-Go

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Pedometer measurement

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Electromyography

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Self-Assessment

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Health related Quality of Life

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

  • Change in Self-Perception

    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.

    Outcome assessed: Before Training (week 0), Mid Training (week 4), After Training (week 8), Follow-Up (week 16)

Interventions

FESDEVICE

FES will be applied via surface electrodes placed over bilateral quadriceps muscles. FES-stimulation will be ramped from sensory level (the level at which the individual feels a cutaneous sensation from the stimulation) to the maximum-tolerated level using a closed loop system controlled by computer software Subjects will exercise at home, three times per week, with FES on for 8 weeks with a goal of attaining 30 minutes of continuous cycling per session. If the individuals are unable to cycle for 30 continuous minutes, rest breaks will be provided with a goal of cycling for a total of 30 minutes. The length of each session will be approximately 45 minutes, with 15 minutes of set-up and 30 minutes of cycling.

Data Sharing

IPD Sharing
Will share

The proposed experiments will generate data for publications in high quality peer reviewed journals. We will also present our findings at national meetings of neurorehabilitation scientists and clinicians and neuroscience and motor control meetings. To have the most impact, it is important that we present our findings to both clinicians and scientists, therefore, in addition to these standard approaches, we will seek out regular opportunities to present both the rationale and results of our work to local and regional clinicians as well as local and regional stroke support groups.
