The Role of Eccentric Training and Pain Neuroscience Education (PNE) to Improve Quadriceps Muscle Strength, and Function in Post ACL Repair: A Case Report

Background: A 19-year-old man presented with right knee pain while bearing weight on the right leg and difficulty bending the right knee. He was diagnosed with a complete -tear of the anterior cruciate ligament. After ACL reconstruction this individual was referred to physical therapy treatment. Objective: To investigate if neuroscience pain education, and eccentric training, have any therapeutic significance in post-ACL reconstructive patients. Method: After assessment, the first day of the first week, introduced a treatment protocol consisting of basic range of motion (ROM) and isometric exercises for three sets of 10–30 sec hold. From first to fourth week eccentric exercises along with pain neuroscience education (PNE) sessions were given on alternate days, with three sessions for PNE and eccentric exercises until fourth week. Result: As shown in this study, treatment with a combination of PNE and eccentric training results in improved quadriceps muscle strength, range of motion, and overall function. Conclusion: This report suggested that PNE in conjunction with eccentric exercise has clinical merit. Clinical implication of study is examining the effectiveness of this approach should be conducted in the form of well-designed, clinical studies.
