Study: NCT04443452

Intervention type: DIAGNOSTIC_TEST
Intervention: Function Assessment (A)
Description: The participant will start in a seated position. The participant will stand up upon therapist's command, walk 3 meters, turn around, walk back to the chair and sit down. The time will stop when the participant is seated. The subject can use an assistive device. If the assistive device is used, it will be documented.~Important Note: A practice trial will be completed before the timed trial.

Intervention type: DIAGNOSTIC_TEST
Intervention: Function Assessment (B)
Description: The 30-Second Chair Test is administered using a chair. The participant is seated in the middle of the chair with arms crossed at the wrists and held against the chest. The participant will practice a repetition or 2 before completing the test. If a participant must use their arms to complete the test, they are scored 0. The participant is encouraged to complete as many full stands as possible within 30 seconds. The participant is instructed to fully sit between each stand. While monitoring the participant's performance to ensure proper form, the tester silently counts the completion of each correct stand. The score is the total number of stands within 30 seconds (more than halfway up at the end of 30 seconds counts as a full stand). Incorrectly executed stands are not counted. The 30-second chair stand involves recording the number of stands a person can complete in 30 seconds rather than the amount of time it takes to complete a pre-determined number of repetitions.

Intervention: Balance Assessment
Description: Static balance and postural sway either in the medial-lateral or antero-posterior direction will be assessed using the RS Scan force plate. The participant will be asked to stand on the plate looking straight forward for 30 seconds in two conditions: first with their eyes open and then with eyes closed. Medial-lateral, antero-posterior and total sway will be recorded.
