Tests and Procedures

The Motion Analysis Laboratory offers a team of specialists and specialized equipment to aid in evaluations for motion studies on patients, including motion capture systems, surface and indwelling electromyography sensors, and multiple strength assessment modalities.

While most testing is done to study walking, the Motion Analysis Laboratory studies any kind of movement.

Elements of a motion study include:

  • How the body moves and forces that cause movement
  • Muscle activity
  • Muscle strength
  • Pressure under the foot while walking

How the body moves and forces that cause movement

The Motion Analysis Lab has two motion capture systems and 10 force platforms to measure human movement in a variety of ground conditions.

Muscle activity

The lab uses surface and indwelling electromyography (EMG) to monitor when muscles are on or off during a movement.

Muscle strength

Staff members in the Motion Analysis Lab have a variety of sensors available to measure muscle strength.

Pressure under the foot while walking

In-shoe pressure profiles are measured to ensure that orthotics and custom footwear are working optimally.
