Ankylosing Spondylitis International Federation. 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 spondyltiis 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. Final scores range from 0 best to 10 worst.

Clinically this is of interest, as it appears that the tragus-to-wall measure does not deteriorate with age to the same extent as other component measures, suggesting this measure is truly disease specific. Metro,ogy t tests, effect sizes ES; mean difference divided by baseline standard deviationand standardized response means SRM; mean difference divided by standard deviation of the difference were used to assess responsiveness.

Ankylosing spondylitis in Rochester, Minnesota, — Meta-analysis of normative cervical motion. Furthermore, such information has the potential to take into account the influence of age, guarding against deterioration being interpreted purely as being associated with the disease process.


As well as helping patients to interpret their BASMI scores, clinicians may find age- and gender-related reference values helpful to inform their understanding and interpretation of spinal mobility in the patients they treat.

Contents Editors Categories Share Cite. Normal range of spinal mobility. The majority of participants were white Caucasian With respect to component BASMI scores, there was a corresponding increase with age that was more pronounced for some spinal mobility measures than others. Evaluation of diagnostic criteria for ankylosing spondylitis: Find articles by Lynne Goodacre.

In contrast, tragus-to-wall distance did not deteriorate, consistently scoring 1 on the component BASMI score across all three age groups Table 2. Tragus to wall distance centimetre tape measure 3.

With regard to lateral lumbar flexion, Finnsback and Mannerkorpi [ 8 ], using a measurement technique consistent with ours in a healthy population, found median scores of 20 cm for both males and females ages 20—49 years, and scores of The Bath Ankylosing Spondylitis Metrology Index BASMI is an index comprising 5 measures of spinal and hip mobility in AS that has been primarily validated in the setting of a physiotherapeutic intervention and has not been validated in relation to functional outcomes.

Future research should also take into account the influence of factors other than age and sex. This is in line with previous research undertaken on spinal mobility by Finnsback and Mannerkorpi [ 8 ] and Intolo et al.

Total Score out of 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.


New threshold values for spinal ankylsoing measures based on a large nationally representative sample of US adults aged 20—69 years splndylitis Arthritis Rheum.

The scale of the BASMI ranges from 0 to 10, where 0 is no mobility limitation and akylosing is very severe limitation [ 5 ]. The patient global assessment is useful in clinical practice, and may be the single most responsive measure in this setting. In most cases Physiopedia articles are a secondary source and so should not be used as references.

The first 8 questions consider activities related to functional anatomy, such as putting on socks with or without help and climbing steps with or without using a handrail. This was based on simulations from a uniform distribution consistent with pilot data [ 12 ]. J R Stat Soc. Measurements were taken by physiotherapists following an agreed protocol.

This work was funded by the National Institute of Health Research. 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 ]. We would therefore recommend similar studies using larger samples in both UK and other populations.
