At the same time, due to the flattening of the sole of the foot, the support of the lower limbs to the whole body is obviously reduced, and the center of gravity of the body is biased to the inside, thus forcing the functions of the whole body and the spine to change.
Physiologically and anatomically, the normal arch of the foot meets the basic requirements of human take-off, which makes people have strong jumping ability. However, we cannot generalize. If the toe joint is strong and can effectively support the human body in fast sports, we may still achieve good results in sprint, even long jump and triple jump.
Endurance events, such as middle-long distance running, ultra-long running, race walking and outdoor weight-bearing marching, are taboo for patients with flat feet.
Extended data
Flat feet can be clinically manifested as:
1, pain
Usually located in the medial plantar (pain in the medial hind foot), it is aggravated after standing or walking for a long time, and it can often be aggravated progressively. Occasionally, pain can also be located near the lateral ankle of the ankle joint. This is the result of heel valgus caused by arch collapse, and then the fibula collided with calcaneus.
2, swelling
Painful extraarticular swelling, especially at the scaphoid tubercle of the foot.
3. Abnormal gait
Foot pain and arch collapse can cause running and even walking ability to decline, and gait is abnormal, such as gait in the outside picture.
4. Pain and abnormal gait
It can affect other joints of the body, such as excessive eversion and pronation of the affected foot, resulting in compensatory eversion of the knee joint and compensatory eversion of the hip joint, which can cause pain and arthritis of the knee, hip and lower back. Individual patients with flat feet may have low back pain as the only symptom.
5. Severe flatfoot deformity
It can be seen that other joints of ankle and foot are involved, such as subtalar joint and transverse tarsal joint, and their flexibility is reduced or even stiff.
6. Flat feet
It may be accompanied by plantar fasciitis and tarsal sinus syndrome.
