Telehealth Physical Therapy for Chronic Back Pain - Ancillary Study to NCT03859713

Observational Study of Telehealth Physical Therapy Provided for Persons With Chronic Low Back Pain

This study evaluated the feasibility of an 8-week physical therapy program for persons with chronic low back pain provided entirely using telehealth with real-time, interactive video sessions with a physical therapist.

At the time of the onset of the COVID pandemic, the research team was conducting a clinical trial (the OPTIMIZE trial) investigating different nonpharmacologic treatments for persons with chronic low back pain (NCT03859713). One intervention arm in this trial is in-person physical therapy. COVID-related restrictions on in-person care prompted suspension of the OPTIMIZE trial. In order to accommodate persons in the midst of receiving treatment at the time of suspension, the study team adapted the in-person protocol for physical therapy for telehealth delivery using two-way, real-time video sessions. Because of the lack of research examining the feasibility of telehealth physical therapy provided in this manner, the study team decided to conduct a pilot study to examine the feasibility of the telehealth protocol.

This study was a prospective, longitudinal cohort of persons with chronic LBP seeking care in one of three healthcare systems; University of Utah Health and Intermountain Healthcare in Salt Lake City, Utah, and Johns Hopkins Medicine in Baltimore, Maryland. All participants were offered up to 8 weekly sessions of telehealth physical therapy. Outcomes included measures of acceptability, appropriateness, feasibility and fidelity as well as effectiveness measures including the Oswestry Disability Index and the PROMIS-29 health domains. Assessments occurred at baseline and after 10- and 26-weeks.

Inclusion Criteria:

• Age 18 - 64 years at the time of enrollment.
• Meets NIH Task Force definition of chronic LBP based on two questions: 1) How long has LBP has been an ongoing problem for you? and 2) How often has LBP been an ongoing problem for you over the past 6 months? A response of greater than 3 months to question 1, and "at least half the days in the past 6 months" to question 2 is required to satisfy the NIH definition of chronic LBP.
• Healthcare visit for LBP in the past 90 days.
• At least moderate levels of pain and disability requiring ODI score >24 and pain intensity rating > 4.

Exclusion Criteria:

• Evidence of serious pathology as a cause of LBP including neoplasm, inflammatory disease (e.g., ankylosing spondylitis), vertebral osteomyelitis, etc.
• Evidence of a specific spinal pathology as the cause of LBP including spine fracture, spinal stenosis, radiculopathy, etc.
• Knowingly pregnant
• Unable to participate in telehealth due to lack of technology or internet access
• Has received physical therapy for LBP in prior 90 days
• Currently receiving substance use disorder treatment
• Any lumbar spine surgery in the past year.
