Study summary

A newly-developed device for biofeedback of surface EMG will be used to either increase or decrease activity in the muscles of children with poor reaching due to cerebral palsy.

Read the detailed description

Children ages newborn to 21 with a diagnosis of arm weakness, hypertonia, or hyperkinesia due to cerebral palsy will be recruited. A muscle that is either over-active or under-active will be selected for each child. The child will be provided with the device to wear for 1 month in order to call attention to the identified muscle. At the beginning and end of the month, reaching will be assessed using three-dimensional kinematic motion capture. The outcome measure will be the speed and curvature of reaching to a target in front of the child.

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.
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 May 23, 2014, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
