Brief Summary

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.

Conditions

Health Adults; Core Stabilization

Keywords

Sacroiliac Joint Manipulation; Core Stabilization; Chriopractic

Outcome Measures

Primary Outcomes (1)

• Trunk Stability Index CTT biofeedback system

  Measurement of trunk stability using the CTT biofeedback system, which evaluates angular deviation and postural control across 22 tilt positions (0° to ±180°). Lower deviation values indicate greater stability.

  Baseline (pre-intervention) and immediately after intervention (within 1 week)

Secondary Outcomes (6)

• Static Core Endurance (Plank Test Duration)

  Baseline and immediately post-intervention (within 1 week)

• Sit-ups Endurance Test

  Baseline and 1 week post-intervention

• Modified Schober Test (Lumbar Flexibility)

  Baseline and post-intervention (1 week)

• Finger-to-Floor Distance (Trunk Flexibility)

  Baseline and post-intervention (1 week)

• Derifield-Thompson Leg Check Test (Pelvic Alignment)

  Baseline and immediately post-intervention

Study Arms (2)

SIJ Manipulation Group

EXPERIMENTAL

Bilateral HVLA SIJ manipulation applied at PSIS

Other: Sacroiliac Joint Manipulation (HVLA)

Control Group (No Treatment)

NO INTERVENTION

Participants received no manipulation; only baseline and post-test evaluations were performed.

Interventions

Sacroiliac Joint Manipulation (HVLA) OTHER

HVLA manipulation applied bilaterally at the sacroiliac joint (PSIS) to improve lumbopelvic stability.
