OBJECTIVES

Rising surgical rates for lumbar spinal stenosis (LSS) and underutilization of physical therapist services for this condition may increase patient risks and healthcare costs. Patient beliefs may also contribute to this problem. Therefore, our objective was to determine which messages about physical therapy were perceived as strongest by patients with LSS and whether those messages were influenced by patient factors.

METHODS

The study used a cross-sectional survey design, and participants were patients of outpatient physical therapy clinics with imaging or clinical evidence of LSS. Participants completed an electronic survey containing different messages about physical therapist services for LSS. Messages were designed using the health belief model. Perceived message strength was scored using the perceived argument strength scale (PASS). Pain catastrophizing and pain self-efficacy were measured to determine whether they influenced participant perceptions. Occurrence of magnetic resonance imaging and surgical consultations were also measured.

RESULTS

Of 189 potential participants, 101 were included in the study. The message perceived as strongest emphasized physical therapists as listeners who would customize a plan (PASS 36.1 [5.0]) Similar scores were seen for messages that emphasized benefits of education and self-management and de-emphasized severity. The message that emphasized research findings was rated the least strong. Participants who had high levels of pain catastrophizing were more likely to have had imaging and perceived arguments as less strong.

DISCUSSION/CONCLUSION: Results of the current study suggested patients with LSS preferred a message that emphasized physical therapists as listeners who would customize a plan. The message about research outcomes was perceived as the least strong. Therefore, awareness campaigns intended to influence the beliefs or behavior of patients with LSS should emphasize the individualized nature of physical therapy more than research evidence.
