The Impact of Dry Needling on Electrophysiological and Ultrasound-based Biomarkers for Myofascial Pain
Trial Parameters
Brief Summary
The goal of this interventional study is to determine how well dry-needling can treat pain in people with Myofascial Pain Syndrome. The main questions it aims to answer are: * Does dry needling improve pain for people with a trigger point (a tender, tight spot in the muscle)? * How well can Electrical Impedence Myography (EIM), Myofiber Threshold Tracking (TT), and Ultrasound (US) detect changes in the muscle related to dry needling treatment? Researchers will compare dry needling to a placebo (a treatment that does not enter the trigger point) to see if dry needling works to treat Myofascial Pain Syndrome with trigger points in the trapezius muscle (the muscle that extends over the back of the neck and shoulders), as measured by these three outcome measures (EIM, US, TT). Participants will: * Visit the clinic twice: once to receive dry needling treatment, and once for a follow-up * Have muscle measurements taken before treatment and at follow-up * Have a daily survey to record the intensity of their pain
Eligibility Criteria
Inclusion Criteria: * Ages 18-80 * Presence of active trigger points with involvement of upper trapezius * Able to manage breakthrough pain with acetaminophen only, excluding stable doses of pain medications at time of enrollment, which can be continued Exclusion Criteria: * Multiple active trigger points in the trapezius muscle if physician assessment concludes that this may interfere with subject's ability to detect changes in pain improvement from trigger point therapy * Presence of cervical radicular pain, superimposed neuromuscular disease or condition that, in the opinion of the investigator, could confound interpretation of the data acquired from trapezius. * Fibromyalgia or other generalized pain condition * Opioid usage in the past 3 months * Active substance use disorder * Not on a stable dose for at least two weeks prior to study enrollment or unwilling to maintain a stable dose for duration of the study of the following drugs: 1. SSRIs, such as citalopram, escitalopram, flu
