The Effect of Eccentric Training and Pain Neuroscience Education (PNE) on Quadriceps Muscle Strength, and Function in Post ACL Repair

In this chapter, we hypothesize the use of PNE in combination with eccentric training program to investigate its effectiveness for the recovery of quadriceps muscle size, strength, and function after reconstruction of complete ACL tear. One of the most common knee injuries is an ACL sprain or tear. Typically, injury occurs during activity/sports play that includes sudden changes in the direction of movement, rapid stopping, jumping and landing abnormally, a direct blow to the lateral aspect of the knee, or slowing down while running. A 19-year-old male complained of pain in his right knee when he tried to bear weight on it and had trouble bending it. His condition was determined to be a full anterior cruciate ligament injury. Following ACL reconstruction, the patient was directed to get physical rehabilitation care. Pain neuroscience education (PNE) has been used as a treatment for chronic pain patients, applying contemporary neuroscience knowledge enabling individuals to rethink their pain experiences.

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.

PNE has already been used to treat a variety of chronic musculoskeletal pain conditions with positive results. The pain biopsychological model focuses on pain neuroscience education, the comprehension of pain experiences, or a positive outlook on life.
