Quantitative and Clinical Description of Postural Instability in Patient Who Underwent Acute Inpatient Rehabilitation and at Follow-Up

To be enrolled in this study, you must be able to walk with or without an assistant device
(such as a cane or a walker).

Study Procedures:

If you are found to be eligible to take part in this study, you will do a combination of
walking and balance tests twice, once on the day you leave the rehabilitation center or
hospital, and again at a return visit 21-60 days (+/-3) later. For the first test, you will
get up from a chair and walk 10 feet as quickly, but as safely, as possible. You will then
return to the chair and sit again. For the second test, you will walk 25 feet, turn around,
and walk back to the starting point as fast and as safely as you can. Both tests will be
timed by the study staff.

You will also do a balance test on a machine. You will stand on a platform with a rail to
hold on to. You will shift your weight and try to keep your balance and center of gravity,
which will be shown on a screen.

You will be given a diary to record any physical exercise you are doing from the time you
leave the rehabilitation center to your return visit 21-60 days (+/-3) later. You will be
asked to record what kind of exercises (home exercise, home health therapy, or outpatient
therapy treatment) you do and for how many hours. It should take about 5 minutes to fill out
the diary each time.

You will complete a questionnaire that asks you about your symptoms, such as pain. You will
complete it when you leave the rehabilitation program and again at the study visit 21-60
days (+/-3) later. It should take about 5 minutes to complete the questionnaire.

Length of Study:

You will be off study after you complete the second questionnaire.

This is an investigational study.
