N2  - OBJECTIVE: To investigate the effects of weight reduction on foot structure, gait, and dynamic plantar loading in obese adults. <br><br>DESIGN: In a 3-month randomized-controlled trial, participants were randomized to receive either a weight loss intervention based on portion-controlled meals or a delayed-treatment control. PARTICIPANTS: 41 adults (32 F, 9 M) with a mean±SD age of 56.2±4.7 years and a BMI of 35.9±4.2kg/m(2). MEASUREMENTS: Arch Height Index (AHI), Malleolar Valgus Index (MVI), spatial and temporal gait parameters, plantar peak pressure (PP) and weight were measured at baseline, 3, and 6 months. <br><br>RESULTS: The intervention group experienced significantly greater weight loss than did the control group (5.9±4.0kg versus 1.9±3.2kg, p=0.001) after 3 months. There were no differences between the groups in anatomical foot structure or gait. However, the treatment group showed a significantly reduced PP than the control group beneath the lateral arch and the metatarsals 4 (all p values<.05) at 3 months. The change in PP correlated significantly with the change in weight at the metatarsal 2 (r=0.57, p=0.0219), metatarsal 3 (r=0.56, p=0.0064) and the medial arch (r=0.26, p<0.0001) at 6 months. <br><br>CONCLUSION: This was the first RCT designed to assess the effects of weight loss on foot structure, gait, and plantar loading in obese adults. Even a modest weight loss significantly reduced the dynamic plantar loading in obese adults. However, weight loss appeared to have no effects on foot structure and gait.<p />  <p>Language: en</p>
