Measures of symptoms and disease status in ankylosing spondylitis: Ankylosing Spondylitis Disease Activity Score (ASDAS), Ankylosing Spondylitis Quality of Life Scale (ASQoL), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Global Score (BAS‐G), Bath Ankylosing Spondylitis Metrology Index (BASMI), Dougados Functional Index (DFI), and Health Assessment Questionnaire for the Spondylarthropathies (HAQ‐S)

Continuous Improvement of Physical Functioning in Ankylosing Spondylitis Patients by Tumor Necrosis Factor Inhibitors: Three‐Year Followup and Predictors

“…It adds important information not obtained with other outcome measures. [32]' The present longitudinal analyses showed that the BASMI remained stable during the 3 years of observation. Furthermore, the baseline BASMI turned out to be the most important variable to influence the 3-year outcome and course of spinal mobility.…”

“…[2] An alternative way to assess the (changes in) spinal mobility on the shorter term is the use of BASMI. The BASMI was developed to quantify the mobility of the axial skeleton in AS patients and to allow objective assessment of clinically significant changes in spinal movement and correlates with radiographic progression [20,32,33] Furthermore, the BASMI has been shown to discriminate well between patients with and without radiographic change due to AS and is sensitive enough to detect change between treatment groups. It adds important information not obtained with other outcome measures.…”

A Possible Correlation Among Different Disease Activity Parameters and Functional Status in Patients with Ankylosing Spondylitis

“…[7] If the ASDAS-CRP is not available, then the ASDAS version with erythrocyte sedimentation rate (ASDAS-ESR) can be used as an alternative. [7,8] Functional status is an important outcome parameter in patients with AS in order to monitor disease effects. [9] The Bath Ankylosing Spondylitis Functional Index (BASFI) is a valid instrument that can be utilized to measure physical function in patients with AS, [8,9] one of the ASAS core elements that was recommended to be measured when following up AS patients.…”
