Abstract

Context: Myofascial Trigger Points (MTrPs) are common causes of pain. Pressure Release (PR) treatments positively affect MTrP Pain Intensity (PI) and Pain Pressure Threshold (PPT), but the results are confusing, which may be due to the type of trigger point treated. Objective: Compare PR treatment efficacy on Active Myofascial Trigger Points (AMTrPs) to Latent Myofascial Trigger Points (LMTrPs). Design: Mixed model. Setting: Laboratory. Patients: Thirty (F:22 M:8, 21.0±2.1 y, ht=171.3±8.1cm, mass=73.8±17.6kg) patients experiencing muscle dysfunction in accordance with university IRB. Interventions: Patient MTrPs were defined as either AMTrPs or LMTrPs. The MTrPs were treated using a common PR method. Independent variables were Trigger Point Type (AMTrP and LMTrP) and Time [before (PreTx) and after (PstTx) treatment]. Main Outcome Measures: Ave. of 3 PI trials to the nearest.1 cm from a 10 cm VAS scale, and ave. of the last 2 PPT trials to the nearest.1 kg/cm2 using an analog algometer. Repeated measures ANOVAs, then 1 X 2 ANONAs and Tukey-Kramer MC tests were used. Alpha was set a priori at.05. Results: The MTrP combined effect on PI decreased over Time from 4.3±0.3 to 2.8±0.3 cm (P < .00001). Trigger Point Type and Time interaction detected (F1,34 = 6.65, P < .014, 1-β = .707) on PPT. The AMTrP group PPT increased from 2.7±0.1 to 3.2±0.1 kg/cm2 (P = .0007), and the LMTrP group PPT increased from 2.5±0.2 to 3.6±0.2 kg/cm2 (P < .00001). MTrP Type differences were not detected at either Time. Conclusion: PI and PPT will respond similarly and positively to PR Tx regardless of MTrP treated.
