Participate in a study of a system to measure the properties of muscles

What is this study about?

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

We are looking for:

• Youth (8-18 years) with diplegic CP
• GMFCS Levels I-II – able to walk and climb stairs while using the railing
• Able to understand English
• Able to walk continuously for 15 minutes without assistive walking devices (such as walkers or ankle-foot orthoses)
• No lower limb amputations

• Only one hour session
• Non-invasive sensors will be superficially attached to 4 different parts along both legs – signals will
• The task is to walk comfortably along a circular path for 15 minutes
• Measurements of muscles vibrations will be recorded with the MMG system

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 (feels like removing a small band-aid)

• Participants will receive a small gift card, to thank them for their time

Recruitment ends April 2017 or when 10 participants have been selected.
