Clinical Trial Summary

The purpose of this study is to determine whether application of Dry Needling (DN) is effective for improved Muscle Mechanical Properties and Muscle Contractility in Latent Trigger Points point (LTrP) of upper trapezius. 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Stiffness	This outcome measure is obtained by a device named MyotonPro. Stiffness reflects the resistance of the muscle to the force deforming the muscle.	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Primary	Change in Maximal Radial Displacement (Dm)	This outcome measure is obtained by a device named Tensiomiography. The variable Dm is given by the radial displacement of the muscular belly in a transverse plane, expressed in millimeters (mm) and depends on muscle tone or stiffness. A low Dm is related to a high muscle tone or an excess of stiffness, while a high Dm value indicates a lack of muscle tone or stiffness defect.	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Oscillation Frequency	This outcome measure is obtained by a device named MyotonPro. The frequency of the damped oscillations characterizes the muscle tone.	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Decrement (elasticity)	This outcome measure is obtained by a device named MyotonPro.The logarithmic decrement of the damping oscillations characterizes muscle elasticity which is the ability of the muscle to restore its initial shape after contraction	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Mechanical Stress Relaxation Time [ms]	This outcome measure is obtained by a device named MyotonPro. Mechanical Stress Relaxation Time [ms] is the time for a muscle to recover tis shape from deformation after a voluntary contraction or a removal of an external force.	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Ratio of deformation and Relaxation time, characterising Creep (Deborah number)	This outcome measure is obtained by a device named MyotonPro. Ratio of deformation and Relaxation time, characterising Creep (Deborah number) is the gradual elongation of a tissue over time when placed under a constant tensile stress.	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Contraction time (Tc)	This outcome measure is obtained by a device named Tensiomiography. Contraction time (Tc) as a time between 10% and 90% of the contraction	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Delay time (Td)	This outcome measure is obtained by a device named Tensiomiography. Delay time (Td) as a time between the electrical impulse and 10% of the contraction	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Sustain time (Ts)	This outcome measure is obtained by a device named Tensiomiography. Sustain time (Ts) as a time between 50% of the contraction and 50% of the relaxation	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Relaxation time (Tr)	This outcome measure is obtained by a device named Tensiomiography. Relaxation time (Tr) as a time between 90% and 50% of the relaxation	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
Secondary	Change in Pressure Pain Perception (PPP)	Change in Pain Pressure Threshold (PPT) as assessed using an manual mechanical algometer. The procedure performed was the same as the prior described, but pressure was kept until 2.5 kg/cm2 and maintained for 5 seconds, whereas the subject had to characterize the level of pain using a 10-mm visual analog scale (VAS)	Baseline, at 30 minutes after treatment, at 24 hours after treatment, at 72 hours after treatment
