“…Through the use of the Baseline and Rocker conditions, each participant functioned as both a test subject and his or her own matched control. Angular joint data from multiple trials within each gait session were combined and then summarized by using Fourier series (Wong, et al, 1983;Fisher, et al, 1993;Klein, 1997) to model the gait pattern in each anatomical plane. The technical details of this analysis procedure have been described previously (Myers, et al, 2005).…”

The use of footwear with contoured soles is common in treatment and care of patients with diabetes; these rocker sole shoes are designed to alleviate loading in key areas on the plantar surface of the foot, reducing pressure in key areas and alleviating pain and potential soft tissue damage. While investigations of pressure changes have been conducted, no quantitative study to date has addressed the three-dimensional kinematic and kinetic changes that result from using these shoes. Forty (40) subjects were tested wearing both unmodified and double rocker sole shoes, and the resulting motion patterns were compared to assess change caused by the rocker sole. Overall walking speed remained unchanged throughout testing; slightly increased flexion (<5°) was apparent at the hip, knee, and ankle during early and midstance. These results demonstrate the maintenance of gait function with minimal kinematic changes when using the rocker sole shoe. Investigations of multisegmental foot motion may reveal additional information about the contour effects; analysis of contour variations may also be warranted to investigate the possibility of controlling motion based on rocker sole parameters.

“…These include: Fourier series, cluster analysis, neural network classifiers and principal component analysis (PCA) [14][15][16][17][18][19]. A technique such as PCA uses the entire waveform in its analysis and may provide better information regarding the quantitative and temporal differences between groups [14,20,21].…”

“…Waveform classifiers attempt to capture the entire gait curve. Such methods may include Fourier analysis [7,8], bootstrap methods [8,9], principal components analysis [10][11][12], and neural network and pattern recognition techniques [13][14][15][16][17][18][19][20].…”
