- High-velocity, low-amplitude manipulation (HVLA) did not have a significant impact on sacroiliac joint range of motion.
BACKGROUND & OBJECTIVE
A common treatment for suspected sacroiliac joint (SIJ) dysfunction is high-velocity, low-amplitude manipulation (HVLA). SIJ motion is limited due to the anatomy of the SIJ and is also impacted by age, gender, weight, and pregnancy status. HVLA is a directed application of force to a ‘dysfunctional’ segment with the intention of treating reversible dysfunction via improvement in segment mobility, muscle relaxation, and reduction of pain. The aim of this study was to analyze the possible alterations in the range of motion of the SIJ following HVLA manipulation of the ilium bone in healthy males.
Studies have found that stabilization exercises result in similar outcomes for SIJ pain and disability when compared to mobilization.
A convenience sample of 30 healthy males between 18 and 35 years of age were recruited to participate in the study. Participants were divided into two groups: placebo and manipulation groups. All procedures were performed by one therapist with a
