Title of Study: Slipping Study: An Investigation into the Role of the Subtalar Joint and the Influence of Footwear characteristics on Foot Function and Dynamic Balance Control During Slip Perturbations

Principle Investigator: Jessica Berrigan

Academic Advisor: Dr. Stephen Perry

Duration of Study: 2.5-3 hours

Description: The purpose of this study is to examine the muscle activity and motions generated around the 'subtalar joint' at the ankle during an unexpected slip recovery.  Furthermore, this study will investigate how certain shoe characteristics affect the ankle during a slip recovery.

Participants: University students (aged 18-30) with no previous severe ankle injury (mild strains/sprains are ok).

Protocol: Participants will be outfitted with Infra-Red Emitting Diods (IREDs) and EMG electrodes placed at specific locations on the body to observe muscle activity and track movements with an Optatrak®  camera system.  Each participant will be asked to walk over a 10m walkway where there is a possibility that a slip may be induced.

This project has been reviewed and approved by the University Research Ethics Board and Dr. Robert Basso.
