Low Back Pain
Conditions
Brief summary
In the daily clinical practice, one of the most frequent reasons for consultation physiotherapists is low back pain (LBP). Regardless of the origin of the problem, the approach from physiotherapy contemplates the reduction of pain through different procedures, including neuromodulation. 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. The objective of the study is to analyze that the effect of PNM on the sciatic nerve produces statistically significant changes in pain, joint range and functionality in patients with chronic LBP. Forty subjects will be recruited, which will be divided into 2 groups: group 1 to which PNM will be applied to the sciatic nerve at 250 microseconds, 3 Hz) during 90 seconds; group 2 to which PNM will be applied to the sciatic nerve in at 250 microseconds, 10 Hz during 90 second. The PNM intervention with NMP will consist in the single application of an asymmetric rectangular biphasic current.
Interventions
Participants received the percutaneous electrical stimulation intervention. Specifically, this consisted of the application of a square wave biphasic electrical current, to cause a tolerable muscle contraction. The application was 10 stimulations of 10 seconds, with 10 seconds at rest between stimulations. A trained physiotherapist performed the PNM intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Level of pain | From baseline measurement up to 1 week | Measured by Visual Analogue Scale (0, no pain; 100, max pain) |
| Owestry questionnaire | From baseline measurement up to 1 week | Lower back pain questionnaire. The final result is classified as minimal disability (0-20), moderate disability (21-40), severe disability (41-60), crippled (61-80) and bed-bound or exaggerating their symptoms (81-100). |
| Range of motion | From baseline measurement up to 1 week | Measured by goniometer. Hip flexion, external and internal rotation range of motion |
| Y Balance Test | From baseline measurement up to 1 week | Stability body |
| Strength | From baseline measurement up to 1 week | Measured by dynamometer. Hip flexion, abduction, external and internal rotation muscle strength |
