 Participants will be assessed by a blinded assessor prior to beginning the intervention and within one week of completing the 10 week program. Pre and post intervention assessment will be spread over two days, each lasting approximately 60 minutes with ample rest periods. Performing the balance and treadmill walking assessments while performing concurrent cognitive tasks may be difficult and participants may lose their balance. The treadmill is equipped with safety side rails which are within easy reach, and participants will be fitted with a safety harness secured above to a support system. Also during all tests, a Physical Therapist will stand behind or beside the participants to provide assistance if required.
