Abstract Summary
The purpose of this study was to determine the effect load carriage has on natural ankle quasi-stiffness (NAS). Fourteen college-aged healthy individuals underwent an instrumented gait analysis while walking over ground at 0.8 statures/second (st/s) under three load carriage conditions. Data were analyzed using a multilevel linear model. Results showed that the participants’ NAS was significantly less on their non-dominant limb compared to their dominant limb (P = 0.009) and significantly greater carrying 20% bodyweight (BW) compared to carrying no load (P = 0.001).
