The purpose of the Mizzou emPOWER program is to meet the curricular needs of entry-level doctorate of physical therapy students by providing them the real-world experience of implementing recent evidence surrounding physical therapy dosing for children with cerebral palsy (CP) for power, strength, and gait interventions while meeting an unmet community need.
Beginning in Fall 2024, the investigators will recruit 6 children with CP, Gross Motor Function Classification System Levels I-III, ages 7-17 years old, to participate in the program. Two students will be assigned to each participant, rotating every 4 weeks due to the structure of the pro-bono clinic. A total of 3 faculty members will supervise. The group will meet for 2 hours, 2 times per week for 15 weeks. Each session will include a 10-minute game-based warm-up, 45 minutes of gait interventions to include treadmill and overground walking as well as other aerobic activities, 45 minutes of resistance training (power and strength training as appropriate for their individual goals), and a 10-minute cool-down incorporating yoga and breathing activities. Participant assessments will be completed during the first week, 7th week, and 15th week. Other programmatic assessments will include students' written reflections on their experiences providing this program, caregiver satisfaction surveys, and participant and caregiver interviews.

Each session will include a 10-minute game-based warm-up, 45 minutes of gait interventions to include treadmill and overground walking as well as other aerobic activities, 45 minutes of resistance training (power and strength training as appropriate for their individual goals), and a 10-minute cool-down incorporating yoga and breathing activities. To ensure participants are exercising at the appropriate level of intensity, 1 repetition maximum measures will be used to determine the appropriate levels of resistance and heart rate monitors will be worn.

Gross Motor Function Measure-88 (GMFM-88)
This is a criterion referenced measure of gross motor function and is valid and reliable for children with cerebral palsy. It evaluates motor skills that are typical for normal development. Dimensions D and E will be utilized, as these 2 sections assess the overall gross motor function in direct relation to standing, walking, running, and jumping.
Time frame: Before PT intervention begins (week 1), midpoint of program (Week 7), and last week of program (week 15).
Canadian Occupational Performance Measure
Evidence-based outcome measure designed to capture a client's self-perception of performance in goals they determine before intervention. The measurement focuses on self-care, leisure activities, and productivity. The participant rates their performance and their satisfaction with their performance on a scale from 1-10, with 1 indicating poor performance and low satisfaction, while 10 indicates very good performance and high satisfaction.
Time frame: Before PT intervention begins (week 1), midpoint of program (Week 7), and last week of program (week 15).
Standing balance with eyes closed standing on firm surface
Participants will stand on a force plate with eyes closed. Postural control information is obtained from the investigators and the force plate tracks the center of pressure of the participant.
Time frame: Before PT intervention begins (week 1), midpoint of program (Week 7), and last week of program (week 15).
