Abstract:

BACKGROUND: The foot is an important part of the human motor system. Foot diseases and injuries have become a troubling problem. Orthopedic insoles can effectively treat and prevent foot diseases and injuries and reduce the risk of injuries. It has become the main method of physical correction.

OBJECTIVE: To clarify the design principles of orthopedic insoles, to classify orthopedic insoles according to the production methods, to sort out the rehabilitation function of orthopedic insoles to human joint-related diseases, children’s hemiplegia, and sports injuries, to explore the current research status and shortcomings of orthopedic insoles, and to make suggestions for future research and development.

METHODS: A search of CNKI, WanFang, Baichain, Baidu Library, and PubMed was performed for relevant literature published from 2005 to 2019. Search terms were “Orthopedic insoles,” “valgus hallux, flat feet, high arch, plantar fasciitis,” “knee varus, knee valgus, knee osteoarthritis,” “scoliosis,” “foot and ankle injury,” “gait,” and “abnormal gaits” in Chinese and “Orthopedic insoles, Corrective effect, Motion pattern characteristics” in English. Included articles were screened, summarized and analyzed.

RESULTS AND CONCLUSION: The design principles of the insoles include four aspects: adjusting the force bearing point of the vola and dispersing plantar pressure; supporting the arch of the foot, improving cushioning ability; improving the force line of the lower limb, providing a stable support; improving proprioception and foot comfort. Orthopedic insoles can be divided into three types: prefabricated, semi-customized and customized. Orthopedic insoles can play an effective prevention and rehabilitation function in ankle, knee, spinal deformity, hemiplegia-type cerebral palsy in children, and sports injuries. Orthopedic insoles have certain limitations in clinical application and in therapeutic effects. In the development and evaluation of orthopedic insoles, the changes in foot shape and shoe shape during human movement should be considered to reflect the concept of “foot-shoe integration.” Different shapes, materials, and hardness of orthopedic insoles can be used to conduct more in-depth research on the effects of orthopedic insoles to prevent and treat injuries and improve exercise capacity.
