Sacroiliac joint (SIJ) dysfunction is a common cause of lumbopelvic instability, often linked to altered load transfer between the spine and lower limbs. Although various therapeutic interventions are used to restore joint alignment and improve neuromuscular control, the immediate effects of chiropractic manipulation on core stabilization in asymptomatic individuals remain unclear. This randomized controlled study aimed to examine the acute impact of bilateral sacroiliac joint high-velocity, low-amplitude (HVLA) manipulation on trunk stability in healthy adults. Sixty participants aged 18-40 years were randomly assigned to either a manipulation group or a control group. Core stabilization performance and postural control were evaluated using standardized tests including the Centaur Trunk Training (CTT) biofeedback system, plank, sit-ups endurance, and flexibility assessments. The findings demonstrated significant short-term improvements in trunk stability and flexibility following manipulation, suggesting that sacroiliac joint adjustments may positively influence neuromuscular activation and motor control in healthy individuals.
