Short-Term Effects of PENS versus Dry Needling in Subjects with Unilateral Mechanical Neck Pain and Active Myofascial Trigger Points in Levator Scapulae Muscle: A Randomized Controlled Trial.

摘要: Procedures such as dry needling (DN) or percutaneous electrical nerve stimulation (PENS) are commonly proposed for the treatment of myofascial trigger points (MTrP). The aim present study is to investigate if PENS more effective than DN in short term subjects with mechanical neck pain. This was an evaluator-blinded randomized controlled trial. Subjects were recruited through announcements and randomly allocated into groups. Pain intensity, disability, pressure pain threshold (PPT), range motion (ROM), side-bending strength measured. analyses included mixed-model variance pairwise comparisons Bonferroni correction. final sample composed 44 (22 per group). Both groups showed improvements intensity (ηp2 = 0.62; p < 0.01), disability 0.74; PPT 0.79; 0.37; 0.01). group greater (mean difference, 3.27; 95% CI, 0.27-6.27) 0.88-1.35; Mixed results obtained ROM. seems produce term.
