Strength and Balance in Gender- and Age-Matched Controls: SubStudy to "The Effects of Vitamin D on Balance in Parkinson's Disease"
The purpose of this study is to learn more about balance and strength in an elderly
population (60 and older). Data will be compared between controls and the age/gender-
matched PD participants in study "The Effects of vitamin D on Balance in Parkinson's
disease" (OHSU IRB # 6482). Specifically a t-test will be used to compare total work and
total power on leg extension and flexion, composite SOT score conditions 1-3 and 4-6,
response strength and latency on MCT, and turn duration from the iMOBILITY between the two
groups.

Inclusion Criteria:
- Over the age of 59
- Gender and Age-Matched (within 3 years) of main protocol participants
Exclusion Criteria:
- Parkinson's disease diagnosis
- Significant cognitive deficits.
- Another neurological or orthopedic deficit that in the investigator's opinion would
have a significant impact on gait and cognition (e.g. stroke, fracture).
This study involves one visit to Oregon Health & Science University. The study visit will
last approximately 2 hours.
Measurements:
1. The participant's balance will be assessed by having them stand on a platform and
completing mental tasks such as naming the alphabet backwards. They will be asked to
have their eyes open on some tasks and closed on other tasks. For safety, they will
wear a harness like those used by rock climbers.
2. The participant's ability to move and balance will be measured by putting six sensors
on their bodies (both wrists, both ankles, chest, and back). Each sensor is about the
size and weight of a deck of cards. To measure movement and balance, participants will
rise from a chair, walk three feet, turn around, walk back to the chair, and sit down.
3. The participant's strength will be evaluated using a machine that resembles a
stationary exercise bike. They will have one leg and foot strapped onto the machine.
Participants will then be asked to flex and extend their leg as quickly as possible
five times. This will be repeated with the other leg.
