Effect of PNF Training as an Intervention for Functional Ankle Instability in College Student

Effect of PNF Training as an Intervention for Functional Ankle Instability in College Student

The lower limb stability test was carried out by MicroSwing 6.0 gravity center moving trajectory tester made in Germany.

The test steps and methods are as follows:

1. Before the test, arrange the subjects to be familiar with the lower limb stability test system and test environment, and master the test method.
2. The subject stands barefoot and one foot in the center of the center of gravity movement trajectory tester, with his hands placed on his sides naturally, and maintains his body balance for 30 seconds.
3. Record data of the test system.
4. The measurement was repeated three times with a time interval of 5min. Collect the test data of the center of gravity moving trajectory tester, including swing frequency, coordination coefficient and stability coefficient, and get the best results of the three tests. The smaller the oscillation frequency and coordination coefficient are within a certain range, the better the stability is. The greater the value of stability coefficient is within a certain range, the better the stability is.

Exclusion Criteria:

1. Does not meet the above diagnostic criteria;
2. Ankle pain caused by infectious diseases;
3. suffering from severe neurological diseases;
4. Soft tissue damage near the ankle joint;
5. Other joints outside the ankle are unstable.
