Physical activity for patients with chronic low back pain: What are physical therapists prescribing?

Physical activity guidelines exist for chronic low back pain, but it's been unclear how physical therapists actually translate those guidelines into what they tell patients in the clinic. This qualitative study interviewed 18 outpatient physical therapists with an average of over 13 years of experience to explore how their physical activity prescriptions align with guidelines, and what shapes their decisions. The interviews suggested that therapists know the guidelines well and value physical activity, but in practice they often prioritize individual patient factors over strict guideline adherence, and they lean on the therapeutic relationship to guide their recommendations. Rather than giving explicit, guideline-based physical activity prescriptions, many offered more general movement advice.

Because this is a small interview-based study reflecting therapists' own accounts rather than observed practice or patient outcomes, the findings describe experience and reasoning, not evidence of what actually works.

If you have chronic low back pain and see a physical therapist, you might expect them to hand you a specific activity plan based on official guidelines, like a set number of minutes of exercise per week. This study looked at what physical therapists actually say to patients, based on interviews with 18 outpatient therapists. What the interviews suggested is that therapists are familiar with the guidelines and believe physical activity matters, but in real sessions they tend to focus more on your individual situation, such as your pain patterns, fears, or daily life, than on hitting a specific guideline target.

They also described the trust and relationship built with a patient as shaping how they frame movement advice, often giving general encouragement to move rather than a strict prescription. Because this study only interviewed therapists and did not measure patient outcomes, it can't tell us whether this approach helps or hinders recovery. It simply offers a window into how therapists think and talk about physical activity for this condition.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

This qualitative study used semi-structured interviews with 18 outpatient physical therapists (mean 13.4 years of clinical experience, SD 6.4) treating chronic low back pain, analyzed thematically to explore alignment between clinical practice and physical activity guidelines. Three themes emerged: therapists demonstrated clear articulated knowledge of physical activity guidelines and their importance; patient-specific factors were consistently prioritized over strict guideline adherence; and the patient-therapist relationship was described as central to how physical activity was framed and delivered. A key finding was that therapists more often gave general movement recommendations rather than explicit, guideline-concordant physical activity prescriptions, suggesting a gap between guideline knowledge and prescriptive behavior in practice.

As a small qualitative sample from outpatient settings, these findings represent self-reported clinical reasoning and experience rather than observed prescribing behavior or measured patient outcomes, and cannot establish effectiveness or generalize prevalence across broader physical therapy populations. The value here lies in identifying barriers and facilitators, such as patient factors and relational trust, that may inform how prescription behavior is studied or supported going forward, without indicating whether any particular approach improves outcomes.
