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

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
NMP in Infrapiriformis level
Participants in this group received NMP of the sciatic nerve in the gluteus region
NMP
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.
NMP in middle thigh level
Participants in this group received NMP of the sciatic nerve in the middle of the thigh
NMP
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.
NMP in middle distal level
Participants in this group received NMP of the sciatic nerve before popliteus region
NMP
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.
