Such information is important to someone who is newly diagnosed and being assessed clinically for the first time, potentially informing their expectations about treatment effects. Support Center Support Center. Paired t tests, effect sizes ES; mean difference divided by baseline standard deviation ajkylosing, and standardized response means SRM; mean difference divided by standard deviation of the difference were used to assess responsiveness.

Evaluation of diagnostic criteria for ankylosing spondylitis: Procedure To address possible inconsistencies in measurement, the ASSIGNw consensus of measurement for each domain was followed [ 12 ]. The Bath Indices are outcome measures zpondylitis with ankylosing spondylitis patients. To address possible inconsistencies in measurement, the ASSIGNw consensus of measurement for each domain was followed [ 12 ].

The Bath Indices – Physiopedia

In total, participants were recruited from a UK population, stratified by gender and age, between September and December Meta-analysis of normative cervical motion. Find articles by Spondy,itis Chilton-Mitchell. Changes in the BASMI and its individual components did not correlate well with changes in functional outcomes. Total Score out of Each component of the BASMI was assessed, with the total score computed using the point scoring system. Contents Editors Categories Share Cite.

Normal range of spinal mobility. Toggle navigation p Physiopedia. Lumbar side flexion centimetre tape measure 4. To accurately assess axial status cervical, dorsal and lumbar spine, hips and pelvic soft tissue of individuals with AS and from these derive a metrology index to define clinically significant changes in spinal mobility.

The Bath Indices

For cervical rotation, tragus-to-wall and lumbar side flexion, the average bqth the right and left measurements was taken [ 4 ]. This therefore highlighted the need for further work to explore if this was a coincidental finding or if in fact this should be expected. Acknowledgements We would like to acknowledge the members of the ASSIGNw, who undertook the measurements for this project, and the volunteers who participated.


Does height influence the assessment of spinal and hip mobility measures used in ankylosing spondylitis? Our aim was to validate the BASMI and its individual components in relation to a validated functional index, the Bath AS Functional Index BASFIand to assess its responsiveness in patients with AS receiving 60 or 10 mg pamidronate monthly for 6 months in a double blind, randomized, controlled trial.

Ethical approval was obtained from the Faculty of Health and Medicine Ethics Committee at Lancaster University and written informed consent was obtained from all participants according to the Declaration of Helsinki.

With this scale in mind, clinicians and patients ankyloskng have expectations that a score of zero is representative of normal spinal movement in a healthy population. Future research should also take into account the influence of factors other than age and sex. Modified Schober Test centimetre tape measure 5. Finnsback C, Mannerkorpi K.

Is the epidemiology changing? In contrast, tragus-to-wall distance did not deteriorate, consistently scoring 1 on the component BASMI score across all three age groups Table 2. National Center for Biotechnology InformationU. For Permissions, please email: That is usually the journal article where the information was first stated.

Published online Aug The patient global assessment is useful in clinical practice, and may be the single most responsive measure in this setting.

Our results also indicate that the magnitude of increase in the BASMI score is more apparent with increasing age.

Spinal and thoracic mobility—age-related reference values for healthy men and women. The only published mettrology data for tragus-to-wall measurements used a seated tragus-to-wall measurement in a population of healthy men and women, and found results consistent with ours, that there is no age-related deterioration [ 8 ].

The Bath Ankylosing Spondylitis Metrology Index BASMI is an index comprising 5 measures of spinal and hip mobility in AS megrology has been primarily validated in the setting of a physiotherapeutic intervention and has not been validated in relation to functional outcomes.

However, as a number of studies have demonstrated age-dependent changes in isolated spinal mobility measurements [ 6—11 ], it would seem reasonable to assume that there are similar changes in the total BASMI score with age, suggesting that it may be more appropriate to interpret BASMI values and changes in values over time in relation to age-specific centiles.

The majority of participants were white Caucasian Results A total of participants with a mean age of Our data indicate that it is unusual for healthy individuals to score zero on the BASMI, which has implications for the interpretation of scores, especially at baseline. The BASMI is used clinically to obtain a baseline measurement and monitor change over time [ 4 ] and to assess the impact of clinical interventions [ 3 ]. Current evidence suggests that the diagnosis of AS most commonly occurs between the ages of 25 and 34 years [ 1516 ].

The scale of the BASMI ranges from 0 to 10, where 0 is no mobility limitation and 10 is very severe limitation [ 5 ]. Please review our privacy policy. Physiopedia articles are best used to find the original sources of information see the references list at the bottom of the article. The BASMI [ 4 ], a composite index of spinal mobility, is used internationally in research and clinical practice and is the measure of spinal mobility recommended by the ASAS [ 3 ]. The loss of spinal mobility is widely recognized as an important clinical sign, spondyliris this is reflected by its inclusion in the Bah New York Criteria for diagnosis [ 2 ], and more recently as a core domain in the evaluation of patients in clinical practice spondylitsi trials by the Assessment of SpondyloArthritis international Society ASAS [ 3 ].
