Therapeutic Effects of Cryotherapy and Transcutaneus Nerves Stimulation on Arthrogenic Muscle Inhibition in Patients With Anterior Cruciate Ligament Reconstruction
Recruitment status was Recruiting
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 transcutaneus electrical nerve stimulation(TENS) can effectively reduce the arthrogenic muscle inhibition caused by experimental swelling.
To exam the effects of 12 weeks cryotherapy and TENS on arthrogenic muscle inhibition in subjects with ACL reconstruction.
Male subjects with isolated ACL injury, age between 18~40 years old are going to receive an ACL reconstruction surgery.
Quadriceps activation level, quadriceps peak torque during maximal voluntary contraction and rate of force development are measure at pre-surgery, 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 will be analyzed using SPSS 13.0 software (SPSS Inc., Chicago, IL). One-way ANOVA will be used to analysis data.
