Neuromuscular control system for functional instable ankles

Abstract

The invention provides a neuromuscular control system for functional instable ankle. The system mainly comprises ligament injury, causing instability and proprioceptive loss as a result of the reduction of neuromuscular control, and repeated injury caused by functional instability. The method is more systematic and accurate than the traditional control methods, and has a significant effect on neuromuscular control on the functional instable ankles.

Description

technical field [0001] The invention relates to the field of medical control, in particular to a neuromuscular control system for functionally unstable ankle joints. Background technique [0002] The ankle joint (calf joint) is the joint most prone to injury in sports, especially during plantarflexion and inversion. Determined by the location of the joint where the injury occurred, the ankle joint accounted for 14%-35%. If determined by the type of injury, sprains accounted for 85% of ankle joint injuries. Yeung et al. and Leanderson et al. reported that basketball players had recurrent ankle sprains The proportions were 70% and 73%, respectively, while the recurrence rate of ankle sprains in general athletes was as high as 80%. The etiology of ankle sprains has always been a major problem in the field of sports medicine research. The causes of ankle sprains are divided into two categories: extrinsic and intrinsic. Extrinsic factors include sports shoes, venues, sports...

Problems solved by technology

However, there is no report on the proprioception in the sagittal plane of the functionally unstable ankle

There are also many controversies about the research on the varus and varus torque of the functionally unstable ankle joint: some scholars focus on the changes in the anatomical structure of the functionally unstable ankle ligaments leading to weakening of muscle strength, and some researchers believe that the valgus of the ankle joint is concentric and centrifugal torque decreased; some researchers pointed out that there is insufficient varus eccentric force in the functionally unstable ankle joint; other scholars believed that there was no significant difference in the varus torque between the functionally unstable ankle joint and the control group; some scholars Point out that there is no decrease in valgus moment in functionally unstable ankle joints

The varus and varus muscles can generate force in all directions, but the dynamic stability of the ankle joint can only rely on the synergy of the surrounding muscles

However, studies on plantarflexion and dorsiflexion moments of functionally unstable ankle joints are very limited and controversial: Termansen et al. pointed out that the plantarflexion centripetal moment of functionally unstable ankle joints was smaller than that of the control group; while McKnight et al. There was no significant difference in plantarflexion and dorsiflexion moments between Ankle Stabilizer and the control group; Schrader found that there was no significant difference in dorsiflexion eccentric peak torque compared with the control group
