Assessing the knowledge of low back pain among physiotherapists in Spain: A cohort study with pre- and post-educational course evaluation

Abstract

Background: Low back pain (LBP) is the most prevalent musculoskeletal disorder worldwide and physiotherapists are among the primary healthcare professionals assessing and treating the condition. However, scientific knowledge regarding the management of LBP amongst physiotherapists is largely unknown.

Objectives: To evaluate the level of evidence-based knowledge among Spanish physiotherapists in LBP management and assess knowledge enhancement following the completion of an e-learning course.

Design: Single-arm cohort study with pre-post evaluation.

Methods: This single-arm pre-post study involved 1350 physiotherapists practicing in Spain. Initially, participants underwent a 22-question test on evidence-based LBP knowledge, covering socio-economic impact, characteristics of LBP, rehabilitation goals, psychosocial factors, and high- and low-value interventions. After completing the course, participants took a final test with the same 22 questions in randomized order.

Results: Out of the 1350 physiotherapists enrolled, 857 completed the course. The initial responses demonstrated that almost half of the participants considered medical imaging essential before starting physiotherapy treatment, perceived glucocorticoids as recommended for chronic low back pain, and considered ergonomic adjustments crucial for managing the condition. Individuals who completed their education more than 10 years ago showed a minor improvement in evidence-based knowledge compared to those who recently finished their university degree. Following the course, participants displayed improved knowledge, narrowing prior disparities in error percentages across questions.

Conclusion: Due to existing gaps in physiotherapists' evidence-based knowledge of LBP, particularly among those who have worked longer time as physiotherapists, e-learning initiatives may be a feasible approach to support continuous training of physiotherapists.
