Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

NMP 3 Hz

Participants received the percutaneous electrical stimulation intervention. Specifically, this consisted of the application of a square wave biphasic electrical current, with 3 Hz frequency and a 250µs pulse width, at the maximal tolerable intensity, to cause an 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.

Group Type EXPERIMENTAL

NMP

Intervention Type OTHER

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.

NMP 10 Hz

Participants received the percutaneous electrical stimulation intervention. Specifically, this consisted of the application of a square wave biphasic electrical current, with 10 Hz frequency and a 250µs pulse width, at the maximal tolerable intensity, to cause an 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.
