Effects of Lumbar Spinal Manipulation in Subjects With Chronic Low Back Pain

Effects of Lumbar Spinal Manipulation on Muscle Mechanical Properties, Pressure Pain Threshold and Mechanical Perception Threshold in Subjects With Chronic Low Back Pain

This study aims to measure the effects of spinal manipulation on Chronic Spinal Pain by assessing Muscle Mechanical Properties (MMPs) using MyotonPRO®, Mechanical Perception Threshold (MPT) using Von Frey monofilaments, and Pressure Pain Threshold (PPT) using an algometer. Participants will be randomly assigned to either spinal manipulation or placebo groups to compare effects on MMPs, MPT, and PPT. Assessments will occur at three time points: baseline, immediately post-intervention (real or simulated), and 24 hours post-intervention. This research targets individuals with chronic spinal pain, providing insights into the potential benefits of spinal manipulation in managing this condition.

Inclusion Criteria:

• Subject with chronic low back pain

Exclusion Criteria:

• Inflammatory or autoimmune disease
• Herniated disc in the segment L5.
• Pregnant women.
• Body Mass Index > 30kg/m2
• Subjects that have received treatment for low back pain in the seven days prior to the study.
