Study summary

Cerebral palsy (CP) describes a group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non progressive disturbances that occurred in the developing fetal or infant brain. The motor disorder of CP are often accompanied by disturbances of sensation, perception, cognition, communication, and behaviour; by epilepsy, and by secondary musculoskeletal problems.

Motor activities, especially walking, can be affected by many factors including sensory deficits, biomechanical and postural limitations, muscle weakness and spasticity.To provide feedback, during gait rehabilitation is a complementary approach to improve motor learning during the rehabilitation protocol. However, the feedback modalities are multiple and no study has compared these modalities. This study aims to test which feedback modalities could control the gait parameters (speed, cadence, step length) of the child with CP in real-time, through an augmented reality environment.

Interventions

  • DeviceFeedback modalities given through an augmented reality headset

    All children wear the augmented reality headset. After a habituation period to the holograms, they start the protocol. It consists of a warm-up session, training session (which three feedback modalities are presented), calibration session (to get the maximal speed and spontaneous speed of the child), and test session. During test session, all the children walk on the 30m corridor. They have 6 feedback modalities + the control, given randomly. On the way out, they have to walk fast as possible ; on the return they have to walk at intermediate speed.

Ran from Jun 2020 to primary completion in Jul 2020, 0 months.

Of 882 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 0 months is below that.

Counting every sponsor, half of 900 studies reached it within 12 months; a quarter within 5 and three quarters within 31.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 23, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
