Effect of therapeutic insoles on the medial longitudinal arch in patients with flatfoot deformity: A three-dimensional loading computed tomography study

Abstract: Background Insoles are frequently used in orthotic therapy as the standard conservative treatment for symptomatic flatfoot deformity to rebuild the arch and stabilize the foot. However, the effectiveness of therapeutic insoles remains unclear. In this study, we assessed the effectiveness of therapeutic insoles for flatfoot deformity using subject-based three-dimensional (3D) computed tomography (CT) models by evaluating the load responses of the bones in the medial longitudinal arch in vivo in 3D. Methods We… Show more

“…In this study, the maximum force and the arch index were effectively decreased not only when walking on a level surface but also when walking up and down stairs after treatment. This result indicates that orthotic insoles could improve the plantar pressure of flatfoot, 25 and the function could be explained by that because the insoles have always been maintaining the proper form of the foot and finally reducing the load-bearing of the midfoot. 26 On the one hand, the largest maximum force and arch index values were in walking down 20-cm stairs, and the second largest were in walking down 10-cm stairs, which may be due to the fact that the plantar pressure is influenced not only by the body weight but also by the acceleration of gravity when a person walks down stairs.…”

“…In this study, the max force and arch index of severe flexible flatfoot were significantly larger than that of normal foot not only when walking on a level surface, but also when walking upstairs and downstairs. This result indicated that the structure of severe flexible flatfoot was deformed badly24 ) due to the instability of its foot arch25 ) .…”

“…Foot radiographs and computed tomography (CT) are the most useful method for analysis of the complex tarsal bones. [11][12][13] The cause of flatfoot includes obesity, posture abnormality, neurology and muscular abnormality, a genetic condition, collagen disorders, and the weakness of supporting tissue. 2 The fat pads may resolve between the ages of 2 and 5 years as the arch of the foot developed.…”
