Study summary

This study is to evaluate how the Wilmington Robotic Exoskeleton (WREX) is working for children who are using the WREX, or have used it in the past. The survey consists of a set of questions a) performed online and b) performed over the phone.

Read the detailed description

The WREX (Wilmington Robotic EXoskeleton) is being used by many children with neuromuscular conditions such as arthrogryposis and muscular dystrophy. Nemours/A.I. duPont Hospital for Children alone has provided a WREX for about 80 children in the last 3 years. This is being done through the orthopedic and muscle clinics in the hospital. We would like to perform a retrospective study to see how well the children are doing with the WREX. We propose getting this feedback through a survey administered to families using the WREX. The survey will be performed in two parts. 1) A phone survey will use the Canadian Occupational Performance Measure (COPM). 2) an online survey with additional questions. The parents are asked to submit answers on behalf of the children if they are unable to.

What researchers measure

Primary outcomes

  1. Canadian Occupational Performance Measure (COPM)

    Performance score on The Canadian Occupational Performance Measure (COPM). The total score range is 1-10. A score of 1 indicates indicates poor performance and low satisfaction and 10 indicates good performance and high satisfaction. The numbers indicate scores on a scale.

    Time frame: Surveys were conducted at a single timepoint for each subject. The surveys were administered over a 4-month period for all the subjects.

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Jul 2014, a primary completion of Oct 2014 and a completion of Jul 2015. It does not say whether these dates are actual or estimated.

Results were first posted in Feb 2024, 9 years 4 months after primary completion.

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 Feb 2, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
