Overview
The goal of this interventional study is to learn about the biomechanical factors underlying the beneficial changes in children with cerebral palsy after using individually-adapted stand-on ride-on power mobility devices (PMD).
The main questions we aim to answer are:
- How does the use of stand-on PMDs affect static balance in children with cerebral palsy?
- How does the use of stand-on PMDs affect dynamic balance and mobility function in children with cerebral palsy?
Children ages 4-6 years old with cerebral palsy (GMFCS levels II and III) will:
- Use individually-adapted stand-on PMDs for three months.
- Undergo tests to measure static balance, dynamic balance, and mobility function before and after the intervention.
- Receive a full biomechanical assessment (kinematics, kinetics, muscle activity, gait spatiotemporal characteristics).
Researchers will compare pre-intervention and post-intervention measurements to quantify improvements in balance, muscle activation, and mobility.
Eligibility
Inclusion Criteria:
- Diagnosis of spastic diplegia CP, GMFCS level III;
- Between 4 and 6 years old (age band selected based on the benefits of early intervention and the age-limitation imposed from the size constraints of the PMDs (toy cars) selected for the intervention);
- Able to stand and to walk short distances (at least 10 meters) with or without external assistance;
- Physician medical clearance to participate; and
- Exhibit sufficient cooperation and attention so that simple verbal instructions can be followed.
Exclusion Criteria:
- Have notable orthopedic conditions (e.g., lower extremity amputation; recent hip surgeries or soft tissue lengthening);
- Inadequate vision to complete study's procedures safely;
- Serious/unstable cardiac conditions that prevent engagement in the Evaluation Sessions; and
- Any other factor that might hinder full participation in the study or confound interpretation of the results.
