Psychometric properties of the Mini-Balance Evaluation Systems Test and physical function measures in patients with Ehlers-Danlos syndrome/hypermobility spectrum disorders
Bibliographic record
Abstract
Purpose Ehlers-Danlos syndrome (EDS) and hypermobility spectrum disorders (HSD) are associated with impairments in balance and physical function. However, the psychometric properties of relevant outcome measures remain largely unexplored. The objectives of this study were to evaluate the construct validity of the Mini-Balance Evaluation Systems Test (Mini-BESTest) alongside the test-retest reliability of the Mini-BESTest, Six Minute Walk Test (6MWT), and Lower Extremity Functional Scale (LEFS) in patients with the hypermobility subtype of EDS (hEDS) and HSD.Materials and Methods Participants with hEDS/HSD (n = 20) attended two visits scheduled one to two weeks apart. The construct validity of the Mini-BESTest was determined through Pearson correlations between force plate balance measures, 6MWT, and LEFS. Test-retest reliability of the measures was evaluated through intraclass correlation coefficients (ICC). Minimal detectable change values with 95% confidence (MDC95) were also calculated.Results Mini-BESTest demonstrated significant correlations with force plate measures, 6MWT, and LEFS (r = −0.41 to 0.66). Test-retest reliability was excellent for the Mini-BESTest, 6MWT, and LEFS (ICC = 0.91 to 0.96). MDC95 was 4 for the Mini-BESTest, 77 m for the 6MWT, and 11 for the LEFS.Conclusion The Mini-BESTest is valid and reliable for assessing balance and mobility in patients with hEDS/HSD.IMPLICATIONS FOR REHABILITATIONThe Mini Balance Evaluation Systems Test (Mini-BESTest) is valid in capturing aspects of balance and physical function in patients with hypermobile Ehlers-Danlos syndrome or hypermobility spectrum disorders.However, the Mini-BESTest may show a potential ceiling effect for high functioning patients in this population.The Mini-BESTest, 6 Minute Walk Test, and the Lower Extremity Functional Scale also show excellent test-retest reliability in this population.The Minimal Detectable Change with 95% confidence intervals is 4 for the Mini-BESTest, 77 m for the 6 Minute Walk Test, and 11 for the Lower Extremity Functional Scale in this population.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
