A pilot survey was conducted to test the feasibility of a larger study designed to determine the MAIL Scale s ability to distinguish two potential subgroups of low back pain inflammatory and mechanical. Methods Patients with a primary complaint of low back pain LBP presenting to chiropractic clinics in Perth Western Australia were asked to fill out the MAIL Scale questionnaire. The instrument s ability to separate patients into inflammatory and mechanical subgroups of LBP was examined using the mean score of each notional subgroup as an arbitrary cut-off point. Results Data were collected from 50 patients. The MAIL Scale did not appear to separate cases of LBP into the two notionally distinct groups of inflammatory n 6 or mechanical n 5 . A larger mixed symptom group n 39 was revealed. Conclusions In this pilot study the MAIL Scale was unable to clearly discriminate between what is thought to be mechanical and inflammatory LBP in 50 cases seen in a chiropractic setting. However the small sample size means any conclusions must be viewed with caution. Further research within a larger study population may be warranted and feasible. Background Low back pain LBP is a common condition with about 79 of Australians experiencing LBP at some time in their lives 1 . In over 85 of cases presenting for primary care 2 a specific cause for pain cannot be identified 3 . In such cases the LBP is often labelled as non-specific low back pain NSLBP . Over 90 of primary contact clinicians .
