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 ...

This study examined the differences in and the reliability of time to stabilization (TTS) of several plyometric exercises. Twenty six men performed a variety of plyometric exercises representing a continuum of intensities of landing instability, including line hops, cone hops, squat jumps, tuck jumps, countermovement jumps, dumbbell countermovement jumps, and single leg countermovement jumps on a force platform. A repeated measures ANOVA with Bonferroni post hoc corrections was used to evaluate the differences in TTS between plyometric exercises. Practitioners who use plyometrics to train dynamic stability and balance should create programs that progress the intensity of the exercises based on ...
