简要总结
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.
详细描述
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.

入选标准
- •Male subject diagnosed with non-specific neck pain and muscle tenderness over the upper trapezius muscle due to an active MTrP
- •Age19-38 years
- •Presence of a maximum of 1-2active MTrPs in a unilateral upper trapezius muscle The number of TrPs in upper trapezius is not limited to two; it may be one or may be more than two (satellite TrPs) also. However, due to time constraints of the study sessions allowed for treatment of up to 2 active MTrPs only.
排除标准
- •Diagnosed with fibromyalgia syndrome according to the American College of Rheumatology criteria;
- •Had active MTrPs in the bilateral upper trapezius muscles
- •Had a history of whiplash injury or cervical spine surgery
- •Were diagnosed with cervical radiculopathy or myelopathy determined by their primary health care physician
- •Had accepted myofascial pain therapy within the 1 month before the study
- •Showed poor cooperation.

结局指标
主要结局
Neck pain intensity
时间窗: Change from baseline VAS scores at day 1 post intervention and after 2-weeks follow-up
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.
Muscle tenderness
时间窗: Change from baseline PPT scores at day 1 post intervention and after 2-weeks follow-up
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.
