Efficacy of Educating Physical Therapists in the Treatment of Patients With Nonspecific Chronic Low Back Pain

The training "Update on the treatment of patients with nonspecific chronic low back pain" will be announced in the social network by members of the study. Interested physical therapists will send an email to one of the study authors with their information regarding the inclusion criteria. After two months of notice, interested and eligible physiotherapists will be randomized into two groups of 15 participants each. The study arms are: 1) control group (physical therapist who will not receive training) and 2) experimental group (physical therapist who will receive training). Before and after training, attitudes, beliefs and knowledge about low back pain guidelines will be evaluated. Each physical therapist will recruit for the study a total of fifteen consecutive patients with chronic nonspecific low back pain (total sample=150 patients). All the patients will be assessed before the first session by a blinded examiner who will be unaware about the group allocation. Clinical outcomes (pain, disability, fear avoidance beliefs and pain catastrophizing) will be collected at baseline and at 5 weeks, 3 and 6 months after randomization. All statistical analysis will be conducted following the principles of intention to treat analysis and the between-group differences will be performed using Mixed Linear Models.
