The Effect Of The Hapad Longitudinal Metatarsal Arch Pad On Ground Reaction Forces And Rear Foot Angle, Rocker Apr 1997

The Effect Of The Hapad Longitudinal Metatarsal Arch Pad On Ground Reaction Forces And Rear Foot Angle, Rocker

Master's Theses

The effectiveness of the Hapad Longitudinal Metatarsal Arch Pad (HLMAP) to correct for pronation was investigated using 30 female volunteer student subjects. The investigation consisted of measuring ground reaction forces measured by a force plate and rear foot angle (RFA) measured by video digitization. The repeated measures design consisted of l grouping variable with 3 levels, supinators, mildpronators, and over pronators, and 2 research variables, 10 trials, and pad/no-pad. The results indicated (a) no significant difference for medial or lateral force, propulsive force, vertic al thrust, negative torque among groups, or between pad/no-pad; (b) a significant difference was ...
