UPDRS and PDQ-39 are reliable and valid assessments of quality of life and physical function in persons with Parkinson’s disease (PD). However, these measures were not designed to track day-to-day or week-to-week changes in community activity in persons with PD.


Twelve individuals with PD (stage 1 to 3, Hoehn and Yahr) who were active members of a health and wellness facility were recruited for this study. Investigators collected health history information, asked questions about the amount and frequency of weekly exercise, and assessed motor symptoms and ADL skills using the UPDRS, and provided participants with Step Activity Monitor (SAM). SAM data were collected for a continuous 7-day period.


Participants averaged 8996 steps/day, had an average of 322 minutes of step activity per day, but were inactive (minIA) 77% of their time per day. On the days that participants visited the health and wellness facility they took an average of 802 more steps with 12 minutes more activity per day.


A SAM can be used to capture activity levels in persons with PD. These pilot data indicate that persons with mild to moderate PD can achieve step activity levels similar to healthy older adults.

This review examined demographic and clinical characteristics of participants from exercise trials in 3 neurologic disability conditions (multiple sclerosis, spinal cord injury, and traumatic brain injury) and compared these data with population-based statistics. The authors included 75 published studies from 2006 to 2016: 53 studies for multiple sclerosis (n = 2,034), 14 for spinal cord injury (n = 302), and 8 for traumatic brain injury (n = 272). Pooled data resembled some heterogeneous aspects of population data sets. However, many characteristics were not reported; samples were small and predominantly White, and 48.1% of the people screened were excluded. Thus, findings from these studies may not be translatable across the range of people with these three conditions, which warrant efforts to target the inclusion of underrepresented subgroups in future exercise trials.
