Background

Ankle sprain, commonly known as foot sprain, is one of the most common sports injuries in orthopedic outpatients, the most common being ankle sprain, which generally results in complete recovery if proper conservative treatment is performed, but still up to 20% of patients develop systemic chronic ankle instability, called CAI for short.

Statistically, chronic unstable ankle joints (CAI) symptoms occur in up to 40% of people who first experience lateral ankle sprain. At present, the global trend of the public participating in sports is gradually rising, the treatment and prevention of ankle sprain become important subjects of sports medicine, and the best treatment of sports medicine is the prevention of injuries. When the patient suffering from CAI is plantarflexed, the medial malleolus and the lateral malleolus are not closely inosculated with the back of the talus, the stability is poor, and ankle joint sprain is easily caused. The lateral malleolus is high, the medial malleolus is low, the lateral collateral ligament is weak, the varus sprain is easy to cause, and a device which is portable to wear and solves the problems of plantarflexion and varus is urgently needed to be designed to prevent CAI.

The user can adjust first fixed band 101 and second fixed band 102 of attatching on the shank through buckle 5, and the comfort level of the most suitable oneself is looked for to dress.

In clinical observation, ankle sprains are mostly composed of plantarflexion and inversion. The angle of plantarflexion is usually 0 to 40 degrees-50 degrees, the angle of dorsiflexion is 0 to 20 degrees-30 degrees, when plantarflexion, the inner and outer ankles are not tightly inosculated with the back of the talus, the stability is poor, and ankle joint sprain is easily caused. The medial malleolus is lower than the lateral malleolus, the medial malleolus is short, the foot varus angle is larger than the valgus angle, the lateral collateral ligament is weak, and varus and sprain are easily caused. The first metatarsal, which is shorter than the second metatarsal by more than 8 mm, is defined as Morten's toe, and is mainly characterized by the second toe being longer than the first toe, and the stability of the forefoot being poor, affecting the stability of the arch. Therefore, we studied a wearable device that senses the trend of angular changes of plantar flexion and inversion during exercise, controls the maintenance or emergency transition to the angular range of dorsiflexion and eversion when dangerous conditions occur, and maintains the stability of the arch of the foot during daily activities to prevent and treat CAI.
