As a medical aid, orthotic insoles can solve and relieve the symptoms of many foot diseases. For different diseases, there are different mechanisms of action. For example, by changing the angle of the foot when it touches the ground and changing the negative focus, people can feel more comfortable and effective when standing, walking, running, and jumping; the support function can correct and improve the user’s gait and posture when walking; by redistributing the plantar pressure, the purpose of treating or relieving plantar diseases can be achieved.
Among the common foot problems, whether the arch of the foot is normal (flat foot, high arch foot) and whether the foot has pronation and supination is the test standard. Deformation of the arch of the foot can lead to a series of foot problems, such as plantar fasciitis/heel spur. Most of the arch collapses and pronation cause the fascia to elongate and tear from the calcaneus. The bone spur is a secondary compensation.
For example, foot tendonitis is mostly caused by pronation and supination. Repeated excessive stretching of the medial and lateral attachment points of the Achilles tendon produces a painful stress point. Pronation and supination are key pathogenic factors. Knee joint pain is mostly due to pronation and supination factors, sprained collateral ligament. Heel pain in children is related to pronation and growth spurts in children and has a greater impact on children who exercise more than sedentary children. Knee joint pain is mostly caused by the combination of tibial torsion, growth spurt, and pronation factors that lead to the occurrence of “tibial tubercle epiphysitis”. Hip pain is due to structural or functional unequal length and supination factors of both lower limbs, including tight external rotation of the hip joint and interference with long lower limbs. Low back pain unilateral and bilateral pronation and structural and functional unequal length of the lower limbs, resulting in poor biomechanical pressure on different parts of the waist.
In the face of these problems, if you know the cause of the disease, you can use appropriate scientific physical rehabilitation methods to alleviate the pain. The purpose of functional orthopedic insoles to deal with the causes of foot pain is not only to relieve the pain symptoms but also to completely get rid of the foot disease. Trouble and the compensation problem of human body mechanics caused by it.
The following describes the role of orthotic insoles in several diseases:
1, Plantar fasciitis
The use of orthotic insoles with arch support can evenly disperse the pressure on the plantar of the patient. It can effectively reduce the tension on the plantar fascia when the lower limbs are weight-bearing, support foot movement, and reduce the damage to the plantar fascia caused by repeated stretching.
2, Calcaneal spur
By redistributing the force on the sole, it reduces the load on the heel and local stimulation to eliminate local inflammation and relieve pain.
3, Achilles tendinitis
In the occurrence of Achilles tendinitis, in addition to external factors such as shoe squeeze and friction, most patients will also have ankle distortion problems, resulting in abnormal stress on the Achilles tendon attachment point. Orthotic insoles can help the Achilles tendon to return to normal stress. At the same time, it can raise the heel and reduce the tension of the Achilles tendon.
4, Metatarsal pain, corpus callosum
By reshaping the arch of the foot, the load on the sole is evenly distributed and the pressure on the forefoot is reduced. There is also an orthotic insole with transverse arch support at the front end, which can reshape the transverse arch so that the collapsed metatarsal head can be raised to varying degrees. This not only can effectively relieve the pain of the forefoot but also can slowly soften the painful foot pad until it disappears.
5, Habitual ankle sprain
Patients with habitual ankle sprains have not only the imbalance of the strength of the ligaments on both sides of the ankle joint but also the inclination of the articular surface of the talus. Orthotic insoles balance the strength of the ligaments on both sides of the ankle joint and improve the inclination angle of the articular surface of the talus, thereby preventing ankle sprain.
6, Tarsal arthritis and intertarsal arthritis
Tarsal arthritis and intertarsal arthritis are caused by aging of the foot muscles and ligaments, which weaken the ability to maintain the joint structure of the tarsal bones, and the Achilles tendon is prone to strain. In some people, there are also reasons for disturbance or loosening of the joint structure between the tarsal bones. Orthotic insoles can stabilize the joint structure by supporting the arch of the foot, thereby reducing the occurrence of traumatic inflammation and eliminating the pain symptoms of patients.
7, Prevention of degenerative osteoarthropathy in the elderly
Orthotic insoles improve the force line of the lower limbs, balance the force of the joints of the lower limbs, and adjust the gait and posture when walking. Long-term use can prevent or delay senile osteoarthropathy.
8, Hallux valgus
The aggravation of thumb valgus is mainly caused by the traction of the plantar muscles. Orthotic insoles can delay the aggravation of thumb valgus by relieving the strength of the sole muscles.
Note: Wearing insoles is an adjuvant treatment and has clear indications. Long-term wear is required to relieve foot problems. During the wearing process, if you feel unwell, please contact your doctor in time or stop wearing it.
Orthotic insoles, like myopia glasses, require strict fitting and tailoring. It turns out that although they are all flat feet, the arches of each person will be different, and even the arches of the left and right feet of the same person may be very different (for example, one foot is flat, the other is normal). People with flat feet are often accompanied by problems such as internal foot, knee valgus, external hip rotation, long and short legs. Each person’s situation is very different.
The doctor will evaluate your whole body’s skeletal development when fitting corrective insoles. It takes 30-60 minutes. All aspects of the body must be considered comprehensively. For example, the thickness of the two insoles of people with long and short legs will be different, so the corrective insole must be tailored, otherwise, the child’s arch abnormality may not be corrected, and the symptoms may even be aggravated.
