ABSTRACT
OBJECTIVE:
The purpose of the present study was to examine the effect of dry needling (DN) on the biomechanical properties of a latent medial myofascial trigger point (MTrP) of the soleus muscle compared with an adjacent point within the taut band (TB) measured by myotonometry.METHODS:
Fifty asymptomatic volunteers were randomly assigned to an intervention group (nâ¯=â¯26) or control group (nâ¯=â¯24). One session of DN was performed in every group as follows 10 needle insertions into the MTrP area (intervention group) or TB area (control group). Myotonometric measurements (frequency, decrement, and stiffness) were performed at baseline (pre-intervention) and after the intervention (post-intervention) in both locations (MTrP and TB areas).RESULTS:
The results showed that stiffness outcome significantly decreased with a large effect size after DN in the MTrP when measured in the MTrP location (Pâ¯=â¯.002; dâ¯=â¯0.928) but not when measured in the TB location. In contrast, no significant changes were observed in any location when the TB was needled (P > .05).CONCLUSIONS:
The findings suggest that only DN into the MTrP area was effective in decreasing stiffness outcome, therefore a specific puncture was needed to modify myofascial muscle stiffness.Palavras-chave
