Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Muscle activation

    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.

    6 months

Study Arms (1)

ice, rate of force development

EXPERIMENTAL

to monitor the long term effect of cryotherapy in rate of force development.

Device: cryotherapy

Interventions

cryotherapy is given with other physical training

ice, rate of force development
