An interventional study of Stand-on ride-on power mobility device in Cerebral Palsy, sponsored by University of North Florida. Completed at 1 site in United States. Open to participants aged 4 Years to 6 Years. Per ClinicalTrials.gov, last updated 2026-09-24.
Sponsored by University of North Florida · Not applicable, Interventional, and Treatment
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:
Children ages 4-6 years old with cerebral palsy (GMFCS levels II and III) will:
Researchers will compare pre-intervention and post-intervention measurements to quantify improvements in balance, muscle activation, and mobility.
1,936 studies on the registry are indexed under Cerebral Palsy; 458 are open to participants now.
This study's enrollment of 10 is below the median of 34 across 1,431 interventional studies indexed under Cerebral Palsy.

Exclusion Criteria:
Children with cerebral palsy received an individually adapted stand-on ride-on powered mobility device for home and community use over a three-month intervention period. Participants completed biomechanical assessments before and after the intervention.
Device: Stand-on ride-on power mobility device
Children will receive the adapted toy car (individually-adapted stand-on PMD) to take home and use for three months. PMD will be used at their house and familiar environments to the family (e.g., neighborhood, parks, schools).
Center of Pressure Sway Area, Standing
Center of pressure sway area during quiet standing was quantified as the 95% confidence ellipse area derived from force plate measurements. Larger sway area values indicate greater postural sway and reduced standing balance stability. Reported values represent the absolute measurements obtained during each of the pre-intervention and post-intervention assessments. For participants completing multiple standing trials at an assessment, the participant-level median across trials was used for analysis. The reported values represent the group median of the participant-level medians for the pre-intervention and post-intervention assessments.
Time frame: Pre (immediately before intervention), Post (3 months post Pre)
Center of Pressure Sway Area, Sit-to-stand
Measure of dynamic balance control during sit-to-stand. Center of pressure sway area during quiet standing was quantified as the 95% confidence ellipse area derived from force plate measurements. Larger ellipse areas indicate greater postural sway. Reported values represent the absolute measurements obtained during each of the pre-intervention and post-intervention assessments. For participants completing multiple standing trials at an assessment, the participant-level median across trials was used for analysis. The reported values represent the group median of the participant-level medians for the pre-intervention and post-intervention assessments.
Time frame: Pre (immediately before intervention), Post (3 months post Pre)
Trunk-pelvis Coupling
Quantification of timing and magnitude of whole-body motor control coordination during functional tasks (e.g., sit-to-stand, walking turns). Trunk-pelvis coupling was quantified using vector coding analysis to characterize coordination between trunk and pelvis motion during the movement task. Reported values represent the absolute measurements obtained during each of the pre-intervention and post-intervention assessments. For participants completing multiple trials at an assessment, the participant-level median across trials was used for analysis. The reported values represent the group median of the participant-level medians for the pre-intervention and post-intervention assessments.
Time frame: Baseline, Pre (3 months post Baseline), Post (3 months post Pre)
Participants with cerebral palsy were recruited through clinical and community outreach associated with the University of North Florida. Eligible participants completed baseline, pre, and post-intervention assessments during participation in the stand-on powered mobility intervention study.

Ran from Jun 2024 to primary completion in Dec 2025, 18 months.
Results were first posted in Aug 2026, 7 months after primary completion.
Of 902 non-industry interventional studies with no phase under Cerebral Palsy, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 31. This study's 18 months is above that.
Counting every sponsor, half of 921 studies reached it within 12 months; a quarter within 5 and three quarters within 31.
