The effect of PNF exercises with a biopsychosocial approach on pain and range of motion after ACL reconstruction

The purpose of this study is to determine the effect of PNF exercises with a biopsychosocial approach on knee range of motion and pain in athletes after ACL reconstruction.

The present research method was experimental (pre-test-post-test) using two experimental groups and one control group. Among all the athletes living in Razavi Khorasan province who underwent arthroscopic knee surgery (complete rupture of the anterior cruciate ligament of the knee) and the specialist, doctor gave them permission to start exercise therapy, 24 of them volunteered to cooperate with the plan and the conditions They entered the study, they were selected purposefully, and then they were randomly assigned to two groups of 12 people. For the experimental group, PNF exercises were performed with a biopsychosocial approach (each group eight weeks: three 45-minute sessions each week), and the control group received only PNF exercises. To collect the necessary information, a goniometer was used to measure the range of motion, and a KOOS questionnaire was used to measure pain and quality of life. Covariance analysis was used to analyze the data.

The results showed that PNF exercises with a biopsychosocial approach are significantly more effective than conventional exercises in improving knee pain (P=0.005) and range of motion (P=0.005).

The results showed that during eight weeks of PNF exercises with a biopsychosocial approach in the rehabilitation center, the progress of most of the research indicators in the experimental group was more than the control group, so the use of these exercises for rehabilitation after ACL reconstruction is suggested.
