One treatment being studied is dry needling, a technique where a small needle is inserted into a specific area of muscle to help relieve pain. So far, the research on dry needling for low back pain hasn't been clear, and it's hard to know when and for whom it will work best. This study aims to figure out how dry needling works to help people with chronic low back pain by looking at the underlying factors. By understanding how dry needling helps people, we can develop a more targeted approach to treatment, which could lead to better outcomes for people with chronic low back pain. The goal of this study is to identify the factors that make dry needling effective for people with chronic low back pain, so that this this information can be used to provide more personalized and effective care.\n\nEligible participants will attend 5 research sessions lasting approximately 1 hour and complete 2 online surveys. At 3 of those sessions, participants will receive dry needling to their low back.\n\nAs part of the research, participants will complete questionnaires related to how pain effects their life. Participants will also undergo testing for muscle stiffness, low back mobility and strength, and pain sensitivity.\n\nTo be included in this study participants must:\n\n* Be 18-65 years of age\n* Have low back pain for at least 3 months"}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
