“…scores correlate with BASMI results and add useful information about rotation and RoK (27). In addition, ES scores have been shown to convincingly differentiate between patients with axSpA and healthy controls and also between patients with ror nr-axSpA (27). Furthermore, in patients with r-axSpA versus those with nr-axSpA, not only was mobility more limited but also tasks were performed more slowly (27).…”

ObjectiveAxial spondyloarthritis (axSpA) is associated with decreased function and mobility of patients due to inflammation and radiographic damage. The Epionics SPINE device (ES), an electronic device that objectively measures spinal mobility, including range of motion (RoM) and speed (RoK) of movement, has been clinically validated in axSpA. We investigated the performance of the ES relative to radiographic damage in the axial skeleton of patients with axSpA.MethodsA total of 103 patients with axSpA (31 non- [nr-] and 72 radiographic [r]- axSpA) were consecutively examined. Conventional radiographs of the spine (including presence, number and location of syndesmophytes) and the sacroiliac joints (SIJs, rated by mNY criteria) were analyzed with the ES and assessments of function and mobility using analyses of covariance and Spearman correlation.ResultsThe number of syndesmophytes correlated positively with BASMI scores (r=0.38;P=0.016) and negatively with chest expansion (r=-0.39;P=0.015) and ES measurements (-0.53 ≤r≤ -0.34,P<0.03) except for RoM and RoK regarding rotation and RoK for extension of the lumbar and thoracic spine. In the radiographic evaluation of SIJs, the extent of damage correlated negatively with ES scores and metric measurements (-0.49 ≤r≤ -0.33;P<0.001). Patients with r-axSpA showed significantly worse ES scores for RoM, RoK and chest expansion than those with nr-axSpA.ConclusionThe ES scores, in accordance with mobility measurements, correlated well with the presence and extent of radiographic damage in the spine and SIJs. As expected, patients with r-axSpA had more severe impairments than those with nr-axSpA.

ObjectiveThe ASAS Health Index (ASAS HI) is a validated patient‐reported outcome (PRO) for global functioning of patients with axial spondyloarthritis (axSpA). The Epionics SPINE (ES) is an electronic device for assessment of axial mobility that provides an objective measure of spinal mobility by assessing range (RoM) and range of kinematic (RoK).The aim of this study is to investigate the relationship between global functioning and clinical measures of disease activity, physical function, spinal mobility, and radiographic damage.MethodsCross‐sectional study‐design, consecutive patients with radiographic (r) and non‐radiographic (nr)‐axSpA were included, and established tools were assessed: BASDAI, BASFI, BASMI, ASAS HI, RoM and RoK using ES. Structural damage of spine and SIJ were assessed by counting the number of syndesmophytes and by NY grading of sacroiliitis. Kendal's tau correlation‐coefficients were calculated.ResultsIn 103 axSpA patients, ASAS HI scores correlated significantly with PRO scores (BASDAI, r=0.36, BASFI, r=0.48 and back pain, r=0.41; all p<0.001). In contrast, no significant correlation between ASAS HI and ROM and ROK (r between ‐0.08 and 0.09) and radiographic damage in SIJ and spine (all r= between 0.03 and 0.004) were seen, respectively. BASMI scores correlated weakly (r=0.14, p=0.05).ConclusionThis study shows that axSpA disease specific PRO's have impact on global functioning whereas spinal mobility scores, even if objectively assessed by the ES, have limited impact on patient reported global functioning. The results also suggest that global functioning is, in this cohort, not much dependent on the degree of structural damage in the axial skeleton.This article is protected by copyright.

Patients with axial spondyloarthritis (axSpA) require close monitoring to achieve the goal of sustained disease remission. Telehealth can facilitate continuous care while relieving scarce healthcare resources. In a mixed-methods proof-of-concept study, we investigated a hybrid telehealth care axSpA pathway in patients with stable disease over 6 months. Patients used a medical app to document disease activity (BASDAI and PtGA bi-weekly, flare questionnaire weekly). To enable a remote ASDAS-CRP (TELE-ASDAS-CRP), patients used a capillary self-sampling device at home. Monitoring results were discussed and a decision was reached via shared decision-making whether a pre-planned 3-month on-site appointment (T3) was necessary. Ten patients completed the study, and eight patients also completed additional telephone interviews. Questionnaire adherence was high; BASDAI (82.3%), flares (74.8%) and all patients successfully completed the TELE-ASDAS-CRP for the T3 evaluation. At T3, 9/10 patients were in remission or low disease activity and all patients declined the offer of an optional T3 on-site appointment. Patient acceptance of all study components was high with a net promoter score (NPS) of +50% (mean NPS 8.8 ± 1.5) for self-sampling, +70% (mean NPS 9.0 ± 1.6) for the electronic questionnaires and +90% for the T3 teleconsultation (mean NPS 9.7 ± 0.6). In interviews, patients reported benefits such as a better overview of their condition, ease of use of telehealth tools, greater autonomy, and, most importantly, travel time savings. To our knowledge, this is the first study to investigate a hybrid approach to follow-up axSpA patients including self-sampling. The positive results observed in this scalable proof-of-concept study warrant a larger confirmatory study.
