PURPOSE: Carrying weight in one hand is a common functional activity. This study investigated the effects of incremental loads carried in one hand unilaterally and its influence on the foot mechanics [plantar pressure, maximum force and contact area]. METHOD: Twenty healthy individuals were tested, in standing and walking, while carrying different weights (no load, 5 kg, 7.5 kg and 10 kg) using their right hand. ANCOVA was conducted separately for the right and left leg to address the effect of incremental loads on the foot mechanics within each leg with navicular drop index and Q angle as covariates. Paired t-test was conducted to address the effect of different loads on the foot mechanics between the legs. RESULTS: Results showed a significant increase in plantar pressure (pCONCLUSION: The fundamental changes in foot mechanics under the influence of different loads may be used to interpret the changes seen in the foot mechanics among different pathological condition.
