Mediolateral Stability During Gait In People With Parkinson's Disease, Sudeshna Aloke Chatterjee Jan 2010

Mediolateral Stability During Gait In People With Parkinson's Disease, Sudeshna Aloke Chatterjee

Graduate Theses and Dissertations

Gait control is a clinical problem in people with Parkinson's disease (PD). Gait variability leading to instability is commonly measured using spatio-temporal variables like step length, step time, step width and cadence. Another measurement that provides information about directional instability is harmonic ratios (HRs). The purpose of this study was to examine the relationship between step width and mediolateral stability using HRs in people with Parkinson's disease (n = 19) and age matched controls (n = 19). The participants walked at their preferred pace and then with a wider step width and narrower step width. The results showed that the ...
