简要总结
Chronic ankle instability (CAI) is a common complication following an ankle sprain, affecting joint stability and leading to decreased muscle strength and poor neuromuscular control. These symptoms can significantly impact athletes' sports performance. Rehabilitation training for CAI majorly involves strengthening or balance training. Few studies have discussed treatment plans that combine the above two training, and the effectiveness of combined training is similar to that of single training content. Due to the lack of machines to train ankle strength, thera-bands were often used for ankle strengthening. However, the resistance thera-bands provide is limited and may need more for athletes requiring high-intensity training. In recent years, a local company has developed a multiaxial ankle training system for machine-based ankle strengthening. This machine allows for training the ankle joint in various directions while sitting and can provide greater training resistance. As this machine has recently been developed and there is seldom evidence for its use in training, this project aims to discuss the effectiveness of using the ankle training machine in athletes with chronic ankle instability. This study will compare the differences in muscle strength, morphology, muscle material properties, balance ability, and functional performance of athletes after a six-week combined training program with thera-band or the multiaxial ankle training system for providing resistance. Thereby establishing a training plan for athletes suffering from chronic ankle instability.

结局指标
主要结局
Muscle Morphology
时间窗: At enrollment (1st. week), midterm of training (3rd. week) and the end of training at 6 weeks
Using ultrasound to measure the muscle morphology of the peronous longus, gastrocnemius, tibialis anterior.
Y-Balance Test
时间窗: At enrollment (1st week), midterm of training (3rd. week) and the end of training at 6 weeks
This test is divided into three directions: anterior, posteromedial, and posterolateral. Each direction has a commercial measuring tape attached at 135 degrees, 90 degrees, and 135 degrees, respectively. The subject stands in the middle of the three measuring tapes, with the test foot's toe placed at the intersection point. The subject then stands on one leg with the test foot, extends the non-weight-bearing foot to touch the measuring tape in the target direction without touching the ground, and returns to the starting position while maintaining balance.
Countermovement Jump
时间窗: At enrollment (1st. week), midterm of training (3rd. week) and the end of training at 6 weeks
Before the test, wireless EMG sensors are attached to the tibialis anterior, The test is performed on a force plate. The subject stands on the force plate, bends both knees to 90 degrees, and jumps as high as possible.
Triple Hop Test
时间窗: At enrollment (1st. week), midterm of training (3rd. week) and the end of training at 6 weeks
The subject stands with both feet at the starting point in front of the force plate, then stands on one foot and performs three consecutive forward hops, with the first hop landing on the force plate.
