Effect of Self-management Intervention on Pain Intensity and Functional Disability in Adolescent Patients With Low Back Pain

"The procedure will be based on the A - B - A'/B' design. After recruitment, patients will attend an initial session with CLS where written and oral information about the study will be provided. In this study, the A phase will serve as baseline to establish fluctuation in pain intensity prior to initiating the treatment.~During phase A, patients will be assessed every day for a minimum of 8 days and maximum of 14 days.~During phase B, CLS will facilitate the intervention based on the initial session, pain levels during phase A and the patients' goals. During phase B, patients will attend a 1-hour weekly session over 6 weeks.~During phase A', the participants will be followed weekly for 12 weeks. During the phase A', participants will not receive treatment.~Phase B' contains 3 x 1 hour criterion-based booster sessions which are delivered over 3 consecutive weeks."
