As a means of external stabilization of the sacroiliac joint (SIJ), many clinicians have often advocated the use of the pelvic compression belt (PCB). The objective of this pilot study was to compare the effects of the PCB on hip extensor muscle activation patterns during one-leg standing in subjects with and without sacroiliac joint pain (SIJP). Sixteen subjects with SIJP and fifteen asymptomatic volunteers participated in this study. Surface electromyography (EMG) data [signal amplitude and premotor reaction time (RT)] were collected from the gluteus maximus and biceps femoris muscles of the supporting leg during one-leg standing with and without the PCB. Compared to that of the asymptomatic individuals, the EMG amplitude of the biceps femoris was significantly decreased in individuals with SIJP upon the application of the PCB (p < 0.05). Furthermore, on using the PCB, in individuals with SIJP, the RT of the gluteus maximus was significantly decreased; however, the RT of the biceps femoris was increased (p < 0.05). Thus, our data support the use of the PCB to modify the activation patterns of the hip extensors among patients with SIJP. Copyright © 2012 Elsevier Ltd. All rights reserved.
