    Study Design

    An intraobserver and interobserver study on the reproducibility of data was performed.


    This study investigates the variability in the interpretation of lumbar spine radiographs by chiropractors working in private practice. of Background Data.

    In chiropractic practice radiographs are used often, but this use is currently under debate.

    Therefore, there is need for further study of the value of diagnoses made by radiographs by chiropractors.

    An acceptable intra-and interobserver agreement in radiograph reading is a prerequisite for a useful application of radiographs as a diagnostic tool in daily practice and in research.


    Four chiropractors read 100 blinded sets of standard, erect anteroposterior and lateral lumbar radiographs independently.

    The same set was read in two separate sessions with a 2 month interval.

    The first ses-sion revealed the interobserver agreement.

    The compar-ison of the ratings by the same assessor in the two sessions indicated the intraobserver agreement.

    The assessors used a specially developed criteria list with emphasis on « nonspecific » radiographic findings.

    The prevalence of some important categories was increased artificially.

    Agreement was expressed in percentage agreement and generalized kappa, combining the resuits of all four assessors.


    Most kappas ranged from 0.40 to 0.75, representing fair to good agreement.

    In general, - intraobserver agreement was better than interobserver agreenent. (...)
