Disability and rehabilitation
-
Knee ligamentous trauma and the following pain is one of the most prevalent athletic injuries. Transcutaneous electrical nerve stimulation is one of the conservative approaches in controlling pain which is low cost, noninvasive, and safe with low complications. Our purpose was to study whether transcutaneous electrical nerve stimulation (TENS) could help athletes perform better during the first phase of rehabilitation (0-4 weeks) after anterior cruciate ligament (ACL) reconstruction surgery and until the follow-up. ⋯ The findings of the present trial shows that adding TENS to a specific protocol of semi-supervised exercise in the first phase of rehabilitation after ACL reconstruction is not efficient on improving knee function and pain more than exercise alone. Implications for Rehabilitation Injury to the anterior cruciate ligament of the knee is a common injury specifically in athletes. Incorporating effective pain relieving strategies during the post anterior cruciate ligament reconstruction surgery rehabilitation could lead to improvement in regaining the range of motion and function of the knee which is of crucial importance after the surgery. Applying transcutaneous electrical nerve stimulation alongside a specific protocol of semi-supervised exercise in the first phase of rehabilitation after anterior cruciate ligament reconstruction did not have any additional effect to exercise alone.
