Abstract

Chiropractic treatments on lumbar vertebrae, which play a critical role in terms of lower extremity functions, are similarly effective in the treatment of functional deficiencies in lower extremity muscles such as rectus femoris, and on muscle tone, elasticity and stiffness. HVLA manipulation was applied to the L2-L3-L4 segments of 39 athletes between the ages of 18 and 60. Muscle tone, elasticity and stiffness were measured on the rectus femoris muscle, before and after the manipulation, using the MyotonPRO device. The measured values were compared in statistical terms. The evaluations were undertaken separately for the right leg and the left leg, and the p value indicating statistical significance was taken as p 0.05. According to the research findings from this study, HVLA manipulation therapy applied to the lumbar region does not cause any significant change in tonus, elasticity and stiffness values of the rectus femoris muscle. There is also no statistically significant difference between the measured values obtained from the right leg and the left leg.HVLA manipulation is known to have successful results in the treatment of many musculoskeletal problems. However, according to the results of our study, there is no statistically significant effect on tonus, elasticity and stiffness in the rectus femoris muscle. © 2023 Elsevier B.V., All rights reserved.
