Effect of Ultrasound-Guided Percutaneous Neuromodulation of Sciatic Nerve on Hip Muscle Strength in Chronic Low Back Pain Sufferers: A Pilot Study

| description | <b>Background:</b> Limited hip internal rotation range of motion (IR-ROM) and hip abductor weakness are recognized in low back pain (LBP) sufferers. The main aim was to investigate the effect of a ultrasound (US)-guided percutaneous neuromodulation (PNM) technique on hip strength in people with LBP. A second purpose was to discover whether the location along the sciatic nerve, where percutaneous neuromodulation was applied, could influence the change of strength response in these patients. <b>Methods</b>: Sixty LBP sufferers were recruited and divided randomly into three groups. All participants received an isolated percutaneous electrical stimulation at one of three different locations of the sciatic nerve pathway (proximal, middle, and distal), depending on the assigned group. Pain intensity, hip passive IR-ROM, hip muscle strength, and the Oswestry disability index (ODI) were analyzed. All variables were calculated before the intervention and one week after the intervention. <b>Results</b>: All interventions significantly decreased pain intensity and improved the IR-ROMs, strength, and functionality after one week (<i>p</i> = 0.001). However, between-group (treatment x time) differences were reported for flexion strength in the non-intervention limb (<i>p</i> = 0.029) and ODI (<i>p</i> = 0.021), although the effect size was small (Eta<sup>2</sup> = 0.1) in both cases. <b>Conclusions</b>: The application of an isolated intervention of the US-guided PNM technique may be a useful therapeutic tool to increase the hip muscle strength in patients with chronic LBP. |
