Performance on Balance Evaluation Systems Test (BESTest) impacts health-related quality of life in Adult Spinal Deformity Patients

STUDY DESIGN:Prospective single-center study OBJECTIVE:This study investigates how dynamic balance performance complements 2D static radiographic measurements and demographics in terms of understanding health-related quality of life in Adult Spinal Deformity (ASD) patients. SUMMARY OF BACKGROUND DATA:Recent insights suggest that demographic variables have a stronger impact on health-related quality of life than 2D radiographic spinopelvic parameters in ASD patients METHODS:9 Healthy volunteers and 36ASD patients following inclusioncriteria were recruited. Demographics, Scoliosis Research Society Score-22r (SRS-22r), OswestryDisability Index (ODI), Core Outcome Measures Index(COMI),2D radiographic spinopelvic measurements and performance on Balance Evaluation Systems Test (BESTest) and Trunk Control Measurement Scale (TCMS) were determined for each subject. Non-parametric tests, Spearman correlations, univariate and stepwise-like linear multivariate regression analysis were performed. RESULTS:BESTest and TCMS had significant lower values in the ASD group versus the control group (p=0,000). In the ASD group, Cumulative Illness Rating Scale (CIRS) correlated fair to ODI, COMI (0,441≥r≥0,383, p
