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.
Time frame: Baseline, approximately 2 days before the end of acute rehabilitation
Biodex Balance System (BBS): Limits of Stability Test (seconds)

Time frame: Baseline, approximately 2 days before the end of acute rehabilitation

Patient's aged 54-71 years' normative scores are 0.9-3.7 scores, 72-89 years' normative scores are 2-4 scores, 36-53 years' normative scores are 0.7-3.1 scores, 17-35 years' normative scores are 0.7-2.1 scores. Change from baseline a fall risk by scores.

Biodex Balance System (BBS): Clinical Test of Sensory Integration of Balance(CTSIB) (sway index)
The test assesses how well a patient can integrate sensory information to maintain balance. Change from baseline the CTSIB test by the patient's sway index, which represents the mean absolute deviation of the patient's average position during a test. The higher the sway index, the more unsteady the person was during the test. Test Trial Time 30 seconds. The test performs with the patient standing on a firm and foam platform with the eyes open and closed. Measure Sway index of Composite Score.
Time frame: Baseline, approximately 2 days before the end of acute rehabilitation
Biodex Balance System (BBS): Balance Error Scoring System (sway index)
A test consists of three positions (Double Leg Stance, Single Leg Stance and Tandem Leg Stance) on two types of platforms (firm and foam) for a total of six conditions. With the Balance System SD, time and error counting is replaced with a measure of sway. Change from baseline balancing errors by Sway index of Composite Score. The higher the sway index, the more unsteady the person was during the test. Test Trial Time 20 seconds
