| Measure | Description | Time Frame |
|---|---|---|
| Biodex Balance System (BBS): Postural Stability Test (Overall stability index) | The BBS will be used to assess postural performance of participants. The movable platform of the BBS allows up to 20° of surface tilt in anterior-posterior and medial-lateral directions. The device is equipped with computer software (Biodex, version 3.1; Biodex Medical Systems). Platform Setting 8. Test Trial Time 20 secs. A high number is indicative of a lot of motion, which is indicative of the patient having trouble balancing. Change from baseline postural stability by overall stability index. |

| Baseline, approximately 2 days before the end of acute rehabilitation |
