Myofascial pain syndrome thought to be the main cause of neck pain and shoulder muscle tenderness in the working population is characterized by myofascial trigger points (MTrPs). This study aimed to examine the immediate and short-term effect of the combination of two therapeutic techniques for improving neck pain and muscle tenderness in patients with upper trapezius Myofascial Trigger points.
Purpose: Myofascial pain syndrome, thought to be the main cause of neck pain and shoulder muscle tenderness in the working population, is characterized by myofascial trigger points (MTrPs). This study aimed to examine the immediate and short-term effect of the combination of two therapeutic techniques for improving neck pain and muscle tenderness in male patients with upper trapezius active MTrPs.
Methods: This was a pretest-posttest single-blinded randomized controlled trial. Sixty male subjects with mechanical neck pain due to upper trapezius active MTrPs were recruited and randomly allocated into group A, which received muscle energy technique (MET) and ischemic compression technique (ICT)along with conventional intervention; group B, which received all the interventions of group A except ICT; and group C, which received conventional treatment only. Baseline (Pr), immediate post-intervention (Po), and 2-week follow-up (Fo) measurements were made for all variables. Pain intensity and pressure pain threshold (PPT)were assessed by a visual analog scale (VAS) and pressure threshold meter, respectively. All three groups received their defined intervention plans only. Repeated-measures analysis of variance was used to perform intra- inter-group analyses. Cohen's d test was used to assess the effect size of the applied interventions within the groups.

|---|---|---|---|
| MET+ICT+Conventional intervention | Experimental | Hot packs (75°C) for 20 minutes and supervised active stretching exercises for upper trapezius muscle (slow, 5 repetitions per session, 10-second hold and 10-second relaxation between two repetitions) followed by ICT (90-second hold-time) and MET (5-second hold-time, 3-second relaxation by exhalation while reaching the new barrier). |

| MET | Behavioral | The patient was in a supine position with the cervical spine in the opposite lateral flexion to the treating part so that the upper trapezius muscle fibers were in a lengthened position.19 The moderate isometric contraction (approximately 75% of maximal) of the upper trapezius muscles was elicited for a period of 5 seconds followed by 3 seconds of relaxation while reaching the new barrier. The technique was repeated four times in each session. |
| Measure | Description | Time Frame |
|---|---|---|
| Muscle tenderness | A pressure algometer used to assess the muscle tenderness by measuring Pressure Pain Threshold (PPT) level of MTrPs as suggested by Fischer. The trigger point with the lowest PPT value was chosen as a primary trigger point. The subjects were instructed to indicate the sensation of pressure they felt from changing from one of pressure to one of pain by saying "there"/ "yes." Three repeated measurements were obtained by the same assistant, and the mean was used in the analysis. At least a 1-minute gap was added between the two repeated measurements as recommended by Fischer. | Change from baseline PPT scores at day 1 post intervention and after 2-weeks follow-up |
| Neck pain intensity | Visual analogue scale (VAS) used to measure neck pain intensity. VAS is a subjective rating scale marked with 0 (No pain) and 10 (extremely unbearable pain) on its either end. An application of 2.5 kg/cm-square of pressure was applied at the rate of 1 kg/cm-square by the physiotherapist while the subjects were stated to rate their pain on the visual analog scale (VAS) to evaluate local pain evoked by the application of that amount of pressure. | Change from baseline VAS scores at day 1 post intervention and after 2-weeks follow-up |

| ICT | Behavioral | The patient lying in the supine position with the cervical spine in opposite lateral flexion to the treating part so that the upper trapezius muscle fibers were kept in a lengthened position.18,22 The physiotherapist applied gradually increasing pressure to the MTrPs until the subject perceived the first noticeable pain. At that moment, the pressure was maintained until the discomfort and/or pain eased by around 50% as perceived by the patient, at which time the pressure was increased until the discomfort appeared again. This process was maintained for 90 seconds. |
|
| Conventional Intervention | Behavioral | Hot packs (75°C) for 20 minutes and active stretching exercises for the upper trapezius muscle (slow, 5 repetitions per session, 10-second hold and 10-second relaxation between two repetitions). Active stretching exercises were done by all the participants under the supervision of the physical therapist. This approach was standardized for all participants. |
