Telerehabilitation for Patients With Chronic Low Back Pain (TeleBACK Clinical Trial)

The investigators will conduct a prospective, randomized, clinical trial addressing key questions to understanding the effectiveness of telerehabilitation (physical therapy delivered via video-visits) and in-clinic physical therapy for patients with chronic low back pain (LBP). The investigators also seek to understand how patients engage with both care options and how these treatment options influence other LBP-related healthcare utilization.

The investigators will explore implementation outcomes using a mixed methods approach consisting of electronic surveys and semi-structured interviews with patients, physical therapists, practice managers, and outpatient services administration focusing on perceived quality and impact on barriers to care. The investigators will enroll 1000 patients with chronic LBP seeking outpatient care at the healthcare systems in Maryland (Johns Hopkins Medicine (JHM)) and Utah (University of Utah (UU) and Intermountain Healthcare (IHC)). Eligible patients will provide informed consent and be randomized to receive telerehabilitation or in-clinic physical therapy delivered by a trained physical therapist. Primary effectiveness outcome is the difference in change in LBP-related disability (Oswestry Disability Index) after 8 weeks of treatment.

Low back pain (LBP) is a nearly universal human experience with 80% of adults having at least one episode in the adult's lifetime and 25% of adults reporting LBP lasting at least 1 day in the past 3 months. Not only is LBP exceedingly common, but it can be very burdensome. The tremendous burden imposed by LBP on health and well-being was recently highlighted in the Global Burden of Disease initiative of the World Health Organization, showing that LBP is associated with greater disability and overall burden for affected individuals than depression, Alzheimer's disease, substance abuse disorders, or arthritis. This high ranking of LBP reflects the sheer number of people who experience the condition and the amount of pain, functional loss, and overall diminishment in quality of life that these individuals experience. It is not surprising that LBP imposes a substantial societal burden being the most common condition encountered in healthcare and the 3rd costliest medical condition, behind only diabetes and heart disease. Despite intensive and expensive treatment efforts, the number of individuals impacted by chronic LBP continues to increase. Ineffective LBP management by health care systems is also contributing to the crisis of opioid over-prescribing.

Physical therapy (PT) has been found to be effective in reducing pain and disability related to LBP and as such, is recommended as the first line of treatment for LBP in clinical practice guidelines. Studies have shown that providing timely access to PT leads to significant decreases in pain and disability compared to usual care and has been associated with decreased odds of receiving advanced imaging, injection, surgery, or opioids over the next year. Despite the benefits of PT, only 7-13% of patients with LBP receive PT services. This low rate of utilization is likely related to barriers surrounding access (i.e., wait times, cost) and logistics (i.e., missed work time, transportation), which have been reported as reasons for not attending PT in previous studies. While these barriers are not unique to PT, the frequency of PT visits (1-3 times per week) and the length of PT care (6-12 weeks) exacerbate already existing barriers to attending in-person visits. Importantly, these barriers are amplified among minority groups and those living in rural areas of the country - minority individuals are 26% less likely than non-minority individuals to receive PT services for musculoskeletal pain.

The COVID-19 pandemic has facilitated the rapid emergence of remotely-delivered PT (i.e., telerehabilitation). Prior to the pandemic, outpatient PT was delivered almost exclusively in-person. However, as the pandemic began, policy changes led to major expansions in the way that PT is delivered. In early 2020, the Center for Medicare and Medicaid Services (CMS) announced temporary authorization for reimbursement of PT services delivered using real-time video visits. Shortly afterwards, the majority of commercial payors followed suit. A non-randomized clinical trial was recently conducted that found that patients with chronic spine pain experienced similar changes in pain, disability and quality of life with multidisciplinary rehabilitation delivered using real-time video visits compared to those that received in-clinic care. A prospective longitudinal study conducted by the study team found that a standardized PT protocol delivered using real-time video visits resulted in significant improvement in disability, pain intensity, pain interference, physical function and sleep disturbance among patients with chronic LBP.

The investigators will compare the effectiveness of telerehabilitation and in-clinic PT for patients with chronic LBP to demonstrated that telerehabilitation will provide non-inferior clinical effects to in-clinic PT.

The investigators propose to enroll 1,000 patients with chronic LBP who present to primary or specialty care at one of three health systems in Baltimore and Utah. Patients will be randomly assigned to receive an 8-session evidence-based PT treatment delivered via in-person or telehealth visits and will be followed for 12 months. Primary outcomes will be disability. Secondary outcomes will be pain intensity and interference, physical function, and patient engagement with treatment. Exploratory outcomes will be mental health, fatigue, social participation, and opioid and other LBP-related healthcare utilization. Moderating factors will be psychosocial risk for poor outcome and pain self-efficacy. Results will provide important information for patients, clinicians, physical therapists, and payers to make informed decisions about optimizing delivery of evidence-based physical therapy to improve quality of life in patients with chronic LBP.
