Combined Therapy and Jones Technique for Upper Trapezius Myofascial Trigger Points

Myofascial trigger points (MTrPs) in the upper trapezius muscle are frequently associated with neck pain, reduced pressure pain threshold, and impaired upper limb function. Several conservative interventions have been proposed for the treatment of MTrPs; however, evidence comparing manual therapy and combined electrotherapy remains limited. This single-center, randomized, sham-controlled, parallel-group clinical trial evaluated the effects of the Jones Technique and combined therapy (therapeutic ultrasound plus transcutaneous electrical nerve stimulation \[TENS\]) in women aged 18 to 40 years presenting with active myofascial trigger points in the upper trapezius muscle. Participants were randomly allocated (1:1:1:1) into four groups: (1) Jones Technique; (2) combined therapy; (3) combined therapy plus Jones Technique; and (4) sham control. Randomization was performed using block randomization stratified by age. Participants underwent a single treatment session. Baseline assessments included demographic data, pain intensity measured using the Visual Analog Scale (VAS), pressure pain threshold measured with a pressure algometer, upper limb disability (DASH), sleep quality (Pittsburgh Sleep Quality Index), quality of life (SF-36), and physical activity level (IPAQ). Immediately after the intervention, pain intensity, pressure pain threshold, and participant satisfaction were reassessed. 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.
