Scope

Scope: This document specifies the method of testing the inversion protection performance of ankle braces using the inversion angle method. This document is applicable to the testing of the inversion protection performance of protective ankle braces. Main technical content: 3. Terms and definitions: The following terms and definitions are applicable to this document. 3.1 Advantage side: Refers to the side of the limb that is more flexible and controlled by the body. 3.2 Ankle brace: A protective device used to prevent ankle injuries or sprains. 3.3 Ankle inversion: The inward movement of the foot, which stretches the lateral ligaments. 3.4 Inversion angle: The acute angle between the axis of the tibia and the axis of the calcaneus. 3.5 Maximum inversion angle: The maximum acute angle between the axis of the tibia and the axis of the calcaneus during ankle inversion. 4. Principle: After volunteers wear the samples, they jump from a standing platform to a landing slope lower than the standing platform to simulate the process of ankle inversion. The maximum inversion angle of the ankle during this process is recorded and measured. By comparing and analyzing the maximum inversion angles of the experimental group and the control group, the inversion protection performance of the samples can be determined. 5. Testing equipment 6.
