Short-Term Effects, on Pressure Pain Threshold, After Applying Techniques Of Isquemic Compression and Traction-Compression- Stretching: A Randomized Clinical Trial
Objectives: The objective of the study was to measure and compare the immediate effect on the pressure pain threshold (PPT), after a single treatment of the latent myofascial trigger point 1 (MTP1) of the upper trapezius muscle, comparing localized ischemic compression (CI) and the integrated neuromuscular traction-compression-stretch technique (TTCE).
Methods: Pre- and post-intervention measurements (at five minutes) of the PPT were made on 30 subjects, 12 men and 18 women, with ages ranging from 24 to 48 years old, asymptomatic, who presented latent MTP1 in upper trapezius, randomly distributed in three groups: G1 (10 subjects) treated with TTCE, G2 (10 subjects) treated with IC and G3 or Control (10 subjects) treated with a simulated myofascial release procedure. The outcome variable, pressure pain threshold (PPT), was measured by a blinded external evaluator regarding the intervention performed. The treatment was performed by an expert operator, blinded to the pre-intervention measurements.
Results:The results showed a significant improvement in the PPT (Control: = 0.00 Vs G1 = +0.42 and G2 = +0.32) after the treatment of MTP1 with TTCE and CI, the improvement being greater in the group treated with TTCE.
Conclusions:The integrated traction-compression-stretch neuromuscular technique (TTCE) could be included in the treatment protocols of the latent MTP1 of the upper trapezius to reduce the pain sensitivity of that trigger point in asymptomatic subjects.
