Every night, open the public WeChat sports, walking steps to five-digit friends abound, less at least three or four thousand, a rough calculation, a person must walk at least one and a half million steps in a year, which is an amazing number ah. Various foot and ankle problems can cause local discomfort and pain when walking, and with the accumulation of steps may also cause adverse effects on other parts of the human body from the bottom up in the long run. About four million years ago, human ancestors began to walk upright, and since then the feet have played a role in bearing the weight of the body and walking on the earth. After a long period of evolution, we were able to acquire the beautiful and functional feet before us, while other structures of the body gradually adapted to the upright posture, allowing us to complete our walking movements with grace and durability. There are 28 bones in the foot and ankle area, which are articulated with each other through multiple groups of ligaments and muscles, forming a stable and flexible structure that can just support the whole body, and softness can cushion the shock and absorb energy to achieve smooth walking under the coordination of neuromuscular. The normal walking cycle includes the standing period and swing period, the standing period accounts for about 62% of the whole cycle, which begins with the heel touching the ground weight-bearing, with the body’s center of gravity moving forward, the plantar stress point from back to forward, in the contralateral toes off the ground, the standing foot is fully weight-bearing, not long after the contralateral heel touching the ground into the swing period, in this process the ankle joint from plantar flexion to dorsal extension position in preparation for the next cycle of heel touching the ground During this process, the ankle transitions from plantar flexion to dorsiflexion in preparation for the next cycle of heel touch. Any problem involving the bones, ligaments, joints, muscles or nerves can cause disruption of the cyclic walking motion, resulting in abnormal gait and subsequent pain and dysfunction. Common foot and ankle disorders include: [valgus deformity, flatfoot deformity, clubfoot deformity, plantar fasciitis, Achilles tendonitis, nail fasciitis, hammertoe, metatarsalgia, osteoarthritis, rheumatoid arthritis, post-traumatic fracture dislocation, ligamentous tendon injury, ankle instability, talar cartilage injury, diabetic foot, etc. Considering the complexity of foot and ankle diseases, it is recommended that you go to a professional foot and ankle surgeon when you experience pain and discomfort in the foot and ankle or have difficulty walking.
