In order to identify subgroups patient characteristics that relate to different outcomes are searched for. However LBP is often fluctuating or recurring rather than clearly limited in time. Therefore it would be relevant to consider outcome after completed treatment from a longitudinal perspective describing course patterns instead of defining it from an arbitrarily selected end-point. Aims The objectives of this pilot study were to investigate the interobserver reliability of a diagnostic classification system and to evaluate whether diagnostic classes or other baseline characteristics are associated with the LBP course pattern over a period of 18 weeks. Methods Patients visiting one of 7 chiropractors because of LBP were classified according to a diagnostic classification system which includes end-range loading SI-joint pain provocation tests neurological examination and tests for muscle tenderness and abnormal nerve tension. In addition age gender duration of pain and presence of leg pain were registered in the patient s file. By weekly SMS-messages on their mobile phones patients were asked how many days they had LBP the preceding week and these answers were transformed into pain course patterns and the total number of LBP days. Results A total of 110 patients were included and 76 69 completed follow-up. Thirty-five patients were examined by two chiropractors. The agreement regarding diagnostic classes was 83 95 CI 70 - 96 . The diagnostic classes .
