Motion Analysis Centre

The Motion Analysis Centre (MAC) at the Janeway Children’s Health and Rehabilitation Centre uses state-of-the-art technology to assess how joints move and to monitor muscle activity during walking.

What we do

A child who has difficulty walking is a candidate for motion analysis. This difficulty may be due to various conditions, such as:

  • Cerebral palsy
  • Spina bifida
  • Brain injury
  • Amputation
  • Stroke
  • Arthritis
Motion analysis typically includes the following:

Video capture
The motion measurement system uses computer-controlled video cameras to record how a person walks. Reflective markers are placed on the skin. The markers are tracked by the cameras and provide information about how the legs move while walking.

Electromyography (EMG)
Special sensors are placed on the skin above the muscles. The sensors measure the electrical activity of the leg muscles, and this information tells the health professional if the muscles are working as they should while the person walks.

Force plates in the floor measure the forces that travel through the legs as the person walks.

Clinical Report
The physician/therapist uses the information from these assessments to complete a report. Motion analysis is not a treatment; however, the information can be used to determine treatment effectiveness or to compare various treatment options.
