Silent Lumbar Disc Herniation Syndrome

An observational study will be conducted on 180 individuals without any back or lower extremity symptoms. Individuals who agree to participate in the study will be divided into 3 groups based on their MRI findings. Group 1 (silent disc herniation group): has LDH and root compression confirmed by the MRI but has no back or lower extremity symptoms. Group 2 (had a history of disc herniation with an improvement of their symptoms after receiving physical therapy intervention): has LDH and root compression confirmed by the MRI but has no back or lower extremity symptoms. Group 3 (control group): absence of LDH and root compression confirmed by the MRI has no back or lower extremity symptoms. The isokinetic peak torque for knee and ankle muscles and the H reflex will be assessed for all the individual investigating the influence of silent LDH on the isokinetic parameters and the H-reflex of the lower extremity may help in better guiding for lower extremity screening to identify individuals at risk for lower extremity injuries. It is hoped that clinicians will incorporate such information to understand the importance of confirming the improvemnt obtained from the physical therapy intervention with an MRI before discharging the patients to reduce the risk of recurrence............................................................................................................................................................................................................................
