Smartphone Accelerometry for Gait Analysis in Children With Unilateral Spastic Cerebral Palsy
Egypt35 participantsStarted 2026-07-01
Plain-language summary
This observational study will evaluate whether a smartphone's built-in accelerometer can provide accurate and repeatable measurements of walking in children with unilateral spastic cerebral palsy.
Thirty-five children aged 6 to 12 years will complete two walking trials along a 10-meter indoor walkway at their usual comfortable speed. During each trial, a smartphone will be secured over the lower back at the L4-L5 level to record body acceleration using the Phyphox application. At the same time, a video camera will record the child's walking for analysis using Kinovea software.
Measurements obtained from the smartphone will be compared with measurements obtained from video analysis. The study will assess walking velocity, cadence, stride timing, and gait asymmetry. The two repeated walking trials will also be used to determine whether the smartphone measurements are consistent when the test is repeated during the same session.
The study does not involve any treatment or change to the child's usual medical or physical therapy care. The purpose is to determine whether smartphone-based gait assessment may be a practical, low-cost method for evaluating walking in children with unilateral spastic cerebral palsy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This study is measuring how well a smartphone can track my child's walking speed, cadence, and gait asymmetry — how does that compare to the gold-standard gait analysis equipment your clinic already uses, and would the results from this study actually change my child's treatment plan?
2Since this trial is listed as Phase NA, which typically means it's an observational or measurement study rather than a treatment trial, can you explain whether my child would receive any new therapy or intervention, or would they just be having their walking analyzed?
3The study focuses specifically on children with unilateral spastic cerebral palsy — does my child's current functional level and type of CP actually match what this trial is looking for, and is there a risk they wouldn't qualify after we start the process?
4If smartphone accelerometry turns out to be a reliable way to track my child's gait at home, how might that change how often we need to come in for in-person assessments, and are there any downsides to relying on that kind of remote monitoring?
5Are there standard clinical gait assessments or therapy programs my child should be doing right now regardless of this trial, and would participating in this study fit alongside those without causing any delays or conflicts in their care?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
