Brief summary
The purpose of this study is to determine whether application of Dry Needling (DN) is effective for reduced on Stiffness in Latent trigger point (LTrP) of upper trapezius. The secondary purposes are to determine the correlation on two elastography for stiffness measure (Shear-wave elastography and Strain elastography). Randomized controlled trial, in parallel with cross-control design. Two groups with LTrP in upper trapezius, and will be randomly selected to DN group or Sham-Dn group.
Interventions
Deep Dry Needling into the site of the latent Trigger Point of the upper trapezius muscle. 1 session in upper trapezius muscle moving the needle up and down ten times.
DEVICEControl-Dry Needling
Sham Dry Needling into the site of the latent Trigger Point of the upper trapezius muscle with non-penetrating needles 1 session in upper trapezius muscle moving the needle up and down ten times.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change on Stiffness (Shear wave elastography and Strain Elastography) | Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment | Shear-wave Elastography (SWE) as assessed using an Logiq S8 US system (GE Healthcare). The stiffness was determined with measuring velocity of shear waves in trapezius muscle on SWE exam. Strain elastography (SEL) as assessed using an Logiq S8 US system (GE Healthcare). The stiffness was determined by applying light repetitive compression with the hand-held transducer |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Pain Pressure Threshold (PPT) | Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment | Pressure-Pain Threshold as assessed by an manual mechanical algometer. PPT is the minimal amount of pressure that produces pain and is used to assess abnormalities in nociceptive processing or hyperalgesia. |
| Change in Thickness of muscle | Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment | The muscle was scanned in the longitudinal and axial planes, taking care to avoid anisotropy. B-Mode gray scale was employed to measure muscle thickness |
| Change in Post-needling soreness | Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment | The procedure performed was the subject had to characterize the level of pain using a visual analog scale (VAS), ranging from 0mm (no pain) to 10mm (worst imaginable pain) |
