The distance walked in 6 minutes is commonly used for assessing an individual's functional exercise capacity. Considerable information is available describing how healthy adults perform this test, including equations that predict results based on factors such as age, sex, or weight. However, these equations do not apply to adults with Parkinson disease (PD), which suggests that unique aspects of PD influence walking and turning abilities. We present a prediction equation that is specific to adults with PD in order to better characterize their functional exercise capacity.
