Supination occurs when a foot rolls out in the event of the gait cycle. The movement is particularly at the subtalar joint inversion, plantar adduction, and flexion. While standing in an upright posture, supination takes place when the foot rolls outwards, putting most of the weight onto the outer side of the foot. This action raises the arch. Supination is normal in the gait cycle that gives way for the foot to form a compact structure for propulsion. Pronation is the opposite of supination.
Sports Injuries and Supination
Over supination takes place mainly among athletes, especially runners. When a foot over supinates, it also underpronates. Pronation helps the foot in shock absorption and mold the surface to the…show more content… These problems include ankle spraining or rolling, developing clawed toes or hammertoes, running injuries that include plantar fasciitis, Achilles tendinitis, general weakness and instability, shin splints and iliotibial band syndrome. The reason oversupination results to a wide range of problems is the fact that muscles in the leg are programmed to push the feet away from the ground mainly with the outer toes.
Causes of Oversupination
There are various reasons that people develop abnormalities. These abnormalities result due to genetics, walking on hard flat surfaces, wearing worn-out shoes, feet overuse, old injuries, muscular compensation resulting from poor posture in the sacrum, legs, and the spine.
Identifying Oversupination
The first step is looking at your foot while standing up. Look for the presence of a high arch on the inside of your foot. Then look for wear and tear on the outside of your shoe's sole especially on the forefoot area. There could be excess supination during running. The third test is doing a wet foot test. Wet your feet and check the footprints that you leave. Normal feet leave a print of the heels, that is connected to the forefoot by a foot lying halfway the width of the feet on the outer part of the
