A Physical Therapy Program Targeting Lower Extremity Selective Motor Control in Children With Spastic Cerebral Palsy (CAMP LEG POWER)

January 7, 2026 updated by: Eileen Fowler, University of California, Los Angeles

Physical Therapy Program for Selective Motor Control

The goal of this intervention study is to learn whether a physical therapy exercise camp called will improve leg movement (motor control) and functional ability in children with spastic CP who are between 5 and 18 years. The main questions the study aims to answer are:

  • Does the ability to move the knee at high velocities improve?
  • Does function such as walking, running, hopping, climbing stairs improve?
  • Will the brain tracts that control movement change?
  • Will children who have better independent control of joint motion improve more?

All participants will:

  • Attend 15 sessions of an exercise camp for 3 hours per day
  • Perform a home exercise program after the camp ends

Measurements:

  • Lower extremity selective motor control
  • Knee muscle strength at high speeds using an exercise machine
  • Gross motor function
  • Gait analysis (walking patterns)
  • Parent's perception of their child's ability and their satisfaction with that ability
  • Change in brain motor tracts using a scanner (MRI) for participants that meet the inclusion criteria for MRI

MRI measurements will be taken twice (before and immediately after the treatment). All other measurements and will be taken 3 times (before, immediately after the treatment and approximately 4 months after the treatment).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Participants who have the intervention
physical therapy exercise intervention
Children practices moving the joints of each lower leg independently.
In sitting, the thigh and trunk are secured to a seat and the lower leg to a moving arm that provides resistance at exercise velocities progressing up to a maximum of 300 deg/s.
With the child in sitting, the ankle is secured to a moving segment. The child can control games such as tennis by dorsiflexing and plantar flexing their ankle at increasing velocities to meet the demands of the game.
The Canadian Occupational Performance Measure is used to identify functional goals. Activities to address these goals are designed by physical therapists and practiced during camp.
Walking barefoot over sand and grass. Foot and ankle sensory exploration using materials with various textures.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Gross Motor Function Measure
Time Frame: nine months
Children are asked to perform functional activities including standing, walking, running, balancing and stair climbing. The data are entered into a computer program to create a score ranging from 0-100. A higher score indicates better function.
nine months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Knee joint torque
Time Frame: nine months
Three repetitions of maximum effort knee extension and flexion torque are collected at 0-300 deg/s for the affected lower limbs. Outcomes are the percent of knee joints that can produce measurable torque at each velocity and the peak joint torque that is produced.
nine months
Canadian Occupational Performance Measure
Time Frame: nine months
Parents/caregivers and children choose 5 activities that they would like to see improve as a result of this intervention. The parent or caregiver rates how well their child currently performs that task and how satisfied they are with the performance of the task on a scale of 1-10 with 10 being the highest score.
nine months
Brain MRI - Diffusion tensor imaging
Time Frame: nine months
A brain MRI scan is obtained. Tract based spatial statistics are performed from the scan to look for changes in individual voxels. Higher values for fractional anisotropy are associated with improved tract integrity. Lower values for radial and median diffusivity are associated with improved myelination.
nine months
