Dynamic Noise Reduction in Accelerometer-based Mechanomyography during Pediatric Gait

Gait Analysis


For this study we are looking into measuring muscle activation during normal walking. We will be comparing a control group of typically developing children to children with walking difficulties. Currently, we are only measuring typically developing children. A non-invasive system called Mechanomyography (MMG) will be used to collect the signals created by muscles while walking.

Are you a typically developing youth? Participate in the study of a sensor to measure muscle properties!

Who can participate

We are looking for:

  • Typically developing youth (8-18 years)
  • No previous musculoskeletal conditions
  • No neurological conditions
  • Able to understand English
  • Does not use any assistive walking devices

What's Involved

  • One half hour session
  • Non-invasive sensors will be attached with medical tape to 4 different parts along both legs
  • The task is to walk comfortably along a circular path for 15 minutes
  • Measurements of muscles vibrations will be recorded with the MMG system
  • Participants will receive a small gift card, to thank them for their time

Potential Benefits: Information from this study may help develop biofeedback sensors used for rehabilitation programs for children.   

Potential Risks: No known potential harms from this study. Some discomfort associated with medical tape and sensor removal
