    Research & Treatment Protocols

    Fix Back & Neck Pain uses methods with published research behind them. Here is what that research found, in plain language, with links to every paper. Study results describe groups of people, not a promise for any one person.

    MedX and isolated strengthening

    MedX machines restrain the pelvis so the lower back muscles do the work on their own. In a randomized trial, the same exercise without the restraint did not build lumbar strength or reduce pain. (Smith et al., 2011)

    In a 1995 study of 895 people with chronic low back pain, 76% of those who completed an isolated lumbar strengthening program reported good or excellent results. At one year, 94% of them said the improvement had lasted. (Nelson et al., 1995)

    In a 1999 study, 60 people who had been told they needed spinal surgery entered an isolated strengthening program. About 16 months later, 3 of the 38 who could be reached had gone on to surgery. The authors noted the study's limits. (Nelson et al., 1999)

    In a 1992 study of 90 people with neck strain or disc problems, eight weeks of isolated cervical strengthening increased neck strength and range of motion and reduced pain. (Highland et al., 1992)

    In a randomized trial of 75 people after lumbar disc surgery, 87% of those who did isolated lumbar extension training returned to work within 4 months, versus 24% of those who did not. (Choi et al., 2005)

    The original MedX research came out of the University of Florida, where the machines were developed and tested. (Pollock et al., 1989)

    Manual therapy and massage

    A 2025 review of 10 randomized trials found that adding manual therapy to exercise improved short-term pain and disability in chronic low back pain more than exercise alone. This is why manual work here follows strengthening rather than replacing it. (Narenthiran et al., 2025)

    A Cochrane review of 25 trials found massage improved short-term pain in chronic back pain, with no serious side effects reported. (Furlan et al., 2015)

    Light and laser therapy

    A Lancet meta-analysis of 16 randomized trials with 820 people found low level laser reduced neck pain. In chronic neck pain, relief lasted up to 22 weeks after treatment, and side effects were no different from placebo. (Chow et al., 2009)

    A 2025 review of 35 trials found low level laser gave more pain relief than minimal treatment in chronic tendon problems, with more sessions linked to more relief. (Yap and Lim, 2025)

    Fascia and Anatomy Trains

    Dissection studies confirm that muscles are joined end to end by connective tissue along several of the lines Thomas Myers described in Anatomy Trains, including the Superficial Back Line. (Wilke et al., 2016)

    In people with long-term low back pain, the layers of fascia in the lower back slide about 20% less than in people without pain. (Langevin et al., 2011)

    What the research does not show yet

    Many of these studies are small or older, and reviewers rate much of the evidence as low certainty. Fascia research shows the connections exist; it has not yet tested whether treating along them relieves back pain. We would rather tell you that plainly.
