Ultrasound-guided neuromodulation to help gluteus muscle weakness after a back pain episode

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, double-blind trial compares two frequency regimens (10 Hz vs 20–100 Hz sweeps) of ultrasound-guided percutaneous electrical neuromodulation targeting the gluteus maximus and gluteus medius. A single treatment is given in week one, with follow-up assessments at 15 and 30 days to measure changes in strength and functional parameters. Participants are adults with a history of non-acute low back pain and measurable gluteal weakness by EMG and dynamometry, recruited from Fiostec Funcional in Sabadell. The study follows CONSORT guidelines for pragmatic trials and aims to determine if frequency sweeps provide greater or longer-lasting functional benefits than fixed 10 Hz stimulation.
