”Flip-flops”, that is, “flip-flops”, are a cool choice for many people in the hot summer. However, from the health point of view, flip-flops are extremely harmful! Here we learn together about the harm of flip-flops to us, as well as coping strategies. Hazard one: tendonitis When walking in flip-flops, the only strap between the toes can not provide enough support surface to lift the flip-flops, in order to firmly hold the shoes, can only rely on the toes in the curled position continuous tension to grip the bottom of the shoes. This constant state can easily lead to toe tendon strain, resulting in toe tendonitis. More serious injuries occur in the Achilles tendon, which connects the posterior calf muscles to the heel bone. When we walk normally, the calf muscles contract to drive the Achilles tendon to pull the heel off the ground. When walking in flip-flops, the Achilles tendon requires more effort to lift the heel due to the lack of support surface on the back of the foot, and this additional burden is the main cause of Achilles tendonitis. The acute phase of Achilles tendonitis will result in pain and stiffness within the Achilles tendon, which will lead to long-term degeneration of the Achilles tendon, making it very easy for the Achilles tendon to tear suddenly during running and jumping. Hazard 2: Arthritis When walking in flip-flops, in order to avoid the embarrassment of falling out of shoes, the center of gravity must lean forward, shorten the stride length, and increase the number of steps, which leads to changes in the sequential nature of the body’s dynamics. Starting from the bottom of the foot, extending to the ankle, calf, knee, hip and spine, causing early degeneration of each joint, recurrent lower limb joint pain and low back pain, and even leading to stress fractures in the lower limbs. At the same time, in order to ensure the control of shoes, the ankle joint turns inward, which will form an “inward eight” deformity in the long run. Hazard three: arch collapse The normal arch can help us cushion the vibration of the joints of the lower limbs when walking and reduce the compression of the blood vessels and nerves on the bottom of the foot. Flip-flop soles are designed to be thin and flat, not only can they not fit the curvature of the foot, but also cannot provide sufficient arch support for the feet, which will eventually lead to atrophy of the plantar muscles and ligaments, collapse of the arch, and induce damage to the joints of the entire lower limb and the neurovascular plantar. So how do we prevent and control “flip-flops” brought about by the injury? Response a, the choice of shoes A pair of suitable shoes should have good arch support and appropriate heel pad height. Recommend about 15mm high soft heel shoes, can reduce the force on the waist, relieve back pain. Professional arch support insoles, to maintain arch shaping, reduce plantar pressure, relieve lower limb fatigue also has a very good effect. Response two, Chinese medicine foot bath daily 10-15 minutes before bedtime Chinese medicine foot bath to relieve a day of exertion brought about by the calf and ankle pain, swelling has excellent results. Chinese medicine foot bath is one of the traditional external treatment methods, the foot for the beginning of the three yin meridians, the end of the three yang meridians, the choice of calves and feet as a bathing area can harmonize the body’s qi and blood, adjusting the function of the internal organs. However, be sure to consult a professional physician or medical institution, according to their own physique, evidence-based selection of appropriate Chinese medicine formula, in order to play a real therapeutic role. After the foot bath can be combined with self-help massage: lightly step on a tennis ball with the foot, using the strength of the foot to gently roll the ball, massage and stimulate the acupuncture points on the bottom of the foot, which is conducive to unblocking the meridians. Response 3: Targeted treatment If there are already obvious symptoms of tendonitis and arthritis, which are difficult to be effectively relieved by the above-mentioned home treatment methods, then professional physical therapy must be carried out in time to avoid the development of the disease. The herbal collapse + TDP treatment carried out in our department, treating to activate blood circulation and remove blood stasis, warming the meridians and opening the channels, has clear efficacy for arthritis pain and synovitis swelling. Infrared polarized light therapy instrument integrates the characteristics of infrared and traditional acupuncture to precisely locate the ganglion, nerve trunk, nerve root, pain affected local and related acupuncture points, which is suitable for treating all kinds of tendonitis and tenosynovitis, with the advantages of safety and effectiveness.
