Ultrasound-guided Neuromodulation Percutaneous

Status Completed

Clinical Trial Summary

Chronic low back pain (LBP) is one of the most familiar musculoskeletal pains and alone has been the main origin of years lived with disability for the past three decades. LBP is identified as a nonspecific, painful or mechanical situation in the lower back, buttocks, or hips. Although an underlying origin in chronic LBP has been proposed to be due to a multitude of factors, a muscle hip disbalance has been recognized5. A limited hip internal rotation range of motion (IR-ROM) and hip abductor weakness were found in patients with LBP symptoms7 In the field of Physiotherapy, ultrasound-guided Percutaneous Neuromodulation (PNM) is defined as the application through a needle with ultrasound guidance of an electrical current at low or medium frequency, seeking a sensitive and / or motor response of a peripheral nerve in some point of its trajectory, or of a muscle in a motor point, with a therapeutic objective. However, authors hypothesize that neuromodulation (especially the US-guided PNM technique) may be used to obtain more therapeutic effects, including pain relief. The main aim of this study was to investigate the effect of hip muscle strengthening by a simple single-shot procedure with the US-guided PNM technique in people with LBP. A second purpose was to discover if the stimulation point in the sciatic nerve territory may influence the change of strength in these patients Sixty subjects will be recruited, which will be divided into 3 groups: group 1 to which PNM will be applied to the sciatic nerve in the gluteus region; group 2 to which PNM will be applied to the sciatic nerve in the middle of the thigh; and group 3 to which PNM will be applied to the sciatic nerve before popliteus region. The PNM intervention with NMP will consist in the single application of an asymmetric rectangular biphasic current (250 microseconds, 3 Hz) during 90 seconds
