Action mechanism of orthopedic insole in several diseases
1、 Plantar aponeurosis: after the application of orthopedic insole, the tension of plantar aponeurosis can be obviously relieved, and the strain can be reduced, so as to eliminate local inflammation and relieve pain.
2、calcaneal spur: after the application of orthopedic insole, the stress on the sole of the foot is redistributed, the load-bearing force on the heel is reduced, and the local stimulation is reduced, so as to eliminate local inflammation and relieve pain.
3、 heel tendinitis: in addition to the external factors of shoe extrusion and friction, most patients have ankle joint twist, which leads to abnormal stress on the Achilles tendon attachment point. After the application of orthopedic insole, the distortion of ankle joint is corrected, so that the Achilles tendon is under normal stress, and the heel tendinitis can heal itself after a long time.
4、metatarsal pain and painful corpus callosum (painful foot pad): after the application of orthopedic insole, the arch of the foot is remolded, so that the load on the sole is evenly distributed, and the stress on the forefoot is reduced. There is also a kind of orthopedic insole, whose front end has a transverse arch supporting pad, which can reshape the transverse arch and raise the collapsed metatarsal head to different degrees. This can not only effectively relieve the pain of the forefoot, but also make the painful corpus callosum soften slowly until it disappears.
5、Habitual ankle sprain: in patients with habitual ankle sprain, there is not only imbalance of ligament strength on both sides of ankle joint, but also inclination of talar joint surface in some patients. The application of orthopedic insole can not only balance the strength of the ligaments on both sides of the ankle joint, but also improve the inclination angle of the talus joint surface, so as to prevent ankle sprain.
6. Tarsometatarsal arthritis and pain of tarsometatarsal arthritis: the occurrence of tarsometatarsal arthritis and tarsometatarsal arthritis, in addition to the aging of foot muscles and ligaments, their ability to maintain the structure of the tarsometatarsal joint is weakened, which makes it easier to strain. In some people, there are disorders or looseness of the structure of the tarsometatarsal joint. After the application of orthopedic insole, it can stabilize the joint structure by supporting the arch of the foot through the insole, thus causing the occurrence of traumatic inflammation and eliminating the clinical pain symptoms.
7. Prevention of senile degenerative osteoarthropathy (knee joint, hip joint, low waist): wearing orthopedic insole for a long time can improve the force line of lower limbs, balance the stress of joints, and adjust the gait and posture of walking, so as to prevent senile osteoarthritis.
Hallux valgus: the aggravation of hallux valgus is mainly caused by the traction of plantar muscles. After the application of orthopedic insole, it can effectively relieve the strength of plantar muscles, so as to delay the aggravation of hallux valgus.
