Abstract

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 found for the interaction effect of groups by pad/no-pad and positive torque; (c) RFA was not significant at foot flat or push-off; (d) RFA was significant at heel strike between the pad/no-pad. The researcher concluded the HLMAP: (a) was effective in controlling positive torque for the over pronators, had no effect on the mild pronators, and a contraindicative effect on the supinators; and (b) caused a greater RFA at heel strike.
