Acute Effects of Thoracolumbar Fascia Myofascial Release on Cortical Activity

This study will examine the immediate (acute) effects of a single myofascial release technique applied to the thoracolumbar fascia on brain activity in healthy young adults aged 18-25. Using a sham-controlled, randomized design, participants will be assigned to either an active treatment group, receiving a 10-minute myofascial release technique to the lower back, or a sham control group, receiving light surface touch to the same area for the same duration without any therapeutic pressure or movement. Brain activity will be recorded using a portable, 8-channel wireless EEG system before the intervention, shortly after it (0-10 minutes), and again 30 minutes later, allowing researchers to track how cortical activity changes over time. Measurements will focus on sensorimotor rhythms (mu rhythm) and posterior alpha power, along with heart rate variability, to assess whether the myofascial technique produces effects that go beyond those of simple touch. The main goal is to determine whether this hands-on technique produces a measurable, distinct pattern of brain activity compared to a sham (placebo-like) touch condition.
