Outcomes of Telehealth Physical Therapy Provided Using Real-Time, Videoconferencing for Patients With Chronic Low Back Pain: A Longitudinal Observational Study

      Abstract

      Objective

      To describe the feasibility of an evidence-based physical therapy (PT) program for persons with chronic low back pain (LBP) originally designed for in-person delivery, adapted for telehealth using videoconferencing.

      Design

      Prospective, longitudinal cohort.

      Setting

      Three health care systems in the United States.

      Participants

      Adults, aged 18-64 years (N=126), with chronic LBP recruited from August through December 2020.

      Intervention

      Up to 8 weekly sessions of telehealth PT.

      Main Outcome Measures

      Follow-up assessments were 10 and 26 weeks after baseline. Participant outcomes collected were the Oswestry Disability Index, Patient-Reported Outcomes Measurement Information System-29 health domains, and pain self-efficacy. Implementation outcomes included acceptability, adoption, feasibility, and fidelity assessed using participant surveys and compliance with session attendance.

      Results

      We enrolled 126 participants (mean age, 51.5 years; 62.7% female). Baseline perceptions about telehealth were generally positive. Eighty-eight participants (69.8%) initiated telehealth PT, with a median of 5 sessions attended. Participants in telehealth PT were generally satisfied (76.3%), although only 39.5% perceived the quality equal to in-person PT. Telehealth PT participants reported significant improvement in LBP-related disability, pain intensity, pain interference, physical function, and sleep disturbance at 10- and 26-week follow-ups.

      Conclusions

      The findings generally support the feasibility of telehealth PT using videoconferencing. Implementation and participant outcomes were similar to in-person PT as delivered in the participating health care systems. We identified barriers that may detract from the patient experience and likelihood of benefitting from telehealth PT. More research is needed to optimize and evaluate the most effective strategies for providing telehealth PT for patients with chronic LBP.
