简要总结
Anterior cruciate ligament(ACL) injury is one of the most common sport injuries. The major problem after ACL reconstruction or rehabilitation program is quadriceps weakness. Previous studies suggested that cryotherapy and transcutaneous electrical nerve stimulation(TENS) can effectively reduce the arthrogenic muscle inhibition caused by experimental swelling.
Objective:
To exam the effects of 12 weeks cryotherapy and TENS on arthrogenic muscle inhibition in subjects with ACL reconstruction.
Design:
Prospective study.
Subjects:
Male subjects with isolated ACL injury, age between 18~40 years old are going to receive an ACL reconstruction surgery.
Methods:
Quadriceps activation level, quadriceps peak torque during maximal voluntary contraction and rate of force development are measure at presurgery, 3-month, 6-month after surgery. After surgery, subjects will receive 12 weeks, 3 days/week, training programs included 20 minutes cryotherapy and exercise training with TENS.
Data analysis:
Data will be analyzed using SPSS 13.0 software (SPSS Inc., Chicago, IL). One-way ANOVA will be used to analysis data.

结局指标
主要结局
Muscle activation
时间窗: 6 months
To provide information of individual muscles for the correlation analyses, parameters of muscle activation, such as the integrated electromyography (EMG) normalized to the maximal M wave, are favored.
