Summary

Myofascial trigger points in the upper trapezius muscle are a common cause of neck pain and may negatively affect pressure pain threshold, upper limb function, sleep quality, and quality of life. This randomized, sham-controlled clinical trial aimed to compare the effects of the Jones Technique, combined therapy (therapeutic ultrasound plus transcutaneous electrical nerve stimulation \[TENS\]), their combination, and a sham intervention in women with active upper trapezius myofascial trigger points. The primary outcome was pressure pain threshold. Secondary outcomes included pain intensity, upper limb disability, sleep quality, quality of life, physical activity level, and participant satisfaction.

Interventions

PROCEDURE

Jones Technique

Manual therapy technique applied to active myofascial trigger points of the upper trapezius muscle. Participants were positioned in prone lying, and sustained pressure with positional release was applied to each trigger point for 90 seconds. Five trigger points were treated during a single treatment session.

DEVICE

Combined Therapy (Therapeutic Ultrasound + TENS)

Combined therapy consisting of pulsed therapeutic ultrasound (1 MHz, 20% duty cycle, 1.0 W/cm²) delivered simultaneously with transcutaneous electrical nerve stimulation (TENS; biphasic asymmetric waveform, 200 μs pulse duration, 100 Hz). Treatment was applied to five active upper trapezius myofascial trigger points during a single 10-minute session.

COMBINATION_PRODUCT

Combined Therapy + Jones Technique

Participants received the Jones Technique followed immediately by combined therapy (therapeutic ultrasound plus transcutaneous electrical nerve stimulation \[TENS\]) during a single treatment session.

PROCEDURE

Sham Intervention

Participants underwent sham treatment consisting of inactive combined therapy with the device turned off and a simulated Jones Technique performed without therapeutic pressure.
