Step Activity in Persons With Parkinson’s Disease

Matthew P. Ford, Laurie A. Malone, Harrison C. Walker, Ildiko Nyikos, Rama Yelisetty, and C. Scott Bickel

Background:

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.

Methods:

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.

Results:

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.

Conclusions:

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.

Characteristics of Adults With Neurologic Disability Recruited for Exercise Trials: A Secondary Analysis

Byron Lai, Katie Cederberg, Kerri A. Vanderbom, C. Scott Bickel, James H. Rimmer, and Robert W. Motl

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.

Clinicians’ Attitudes, Perspectives, and Clinical Practices on Gait Retraining After Anterior Cruciate Ligament Reconstruction

Kyle Southall, Laura Vogtle, Harshvardhan Singh, Matthew P. Ithurburn, C. Scott Bickel, and Christopher P. Hurt

Introduction: It has been shown that 45%–85% of patients with anterior cruciate ligament reconstruction (ACLR) will have early-onset arthritis within 10–12 years following surgery. Over the past two decades, the amount of literature regarding ACLR, gait maladaptations after ACLR and their potential link to early-onset arthritis, and rehabilitation techniques has grown exponentially; however, long-term patient outcomes remain modest. Methods: To evaluate current clinicians’ attitudes, perspectives, and clinical practice approach for rehabilitation of patients following ACLR, a survey questionnaire was designed using the Delphi technique. Results: Of the 263 respondents, 84.4% (n = 226) reported that they believed gait training to be “Very” or “Extremely Important.” However, only 35.7% (n = 94) reported objectively measuring gait during ACLR rehabilitation. Of the total respondents, only 6.8% (n = 18) assessed gait during rehabilitation using two-dimensional or three-dimensional motion capture technologies. Discussion: Our results suggest that while gait evaluation was perceived as important, most respondents did not objectively measure gait metrics as a clinical outcome during ACLR rehabilitation. These findings provide a prospective rehabilitation target to potentially mitigate a known risk factor of early-onset arthritis (gait maladaptations) in individuals following ACLR.
