Effects of Hip Strength Training and Neuromuscular Electrical Stimulation on Functional Ankle Instability

The program included ankle elastic band resistance training and balance training, in which the elastic band resistance training required subjects to complete resistance training in ankle plantarflexion, dorsiflexion, inversion and eversion directions with the help of elastic bands; and the balance training required subjects to complete the movements of standing with eyes open, standing with eyes closed, and throwing and catching the ball on flat ground and BOSU ball.

Hip strength training required subjects to complete resistance training in hip abduction and posterior extension, anterior step-up and lateral step-up exercises with the help of elastic bands.

Neuromuscular electrical stimulation of the gluteus mediums and gluteus maximus muscles of the affected side was carried out using the TB6807 low-frequency therapeutic instrument (with prescription for neuromuscular electrical stimulation) manufactured by China Tangbang Science and Technology Company.
