Background
Aquatic therapy is reported to have positive effects on mobility in persons with disabilities. However, there is no validated tool for assessment of aquatic performance that can be compared with physical function on land. This study aimed to develop an aquatic performance measure for rehabilitation therapy based on Water Orientation Test Alyn (WOTA), which was developed for both swimming activity and aquatic rehabilitation therapy. We also investigated the validity of the new scale in comparison with on-land activities.
Methods
Patients with brain lesions (traumatic brain injury and stroke) and spine injuries (spinal cord injury, spine fracture, and cauda equina syndrome), who underwent aqua therapy and WOTA assessment, were retrospectively reviewed. Twenty-one WOTA items, excluding 16 items related to swimming activities, were categorized through exploratory factor analysis (EFA). Confirmatory factor analysis (CFA) was performed to evaluate the validity of the structure of the new functional evaluation tool. Spearman’s correlation analyses were completed with the Medical Research Council (MRC) sum score and modified Barthel index (MBI) score.
Results
Ninety-five patients (mean age: 53.4 years, range: 27–73 years) were included in the analysis. WOTA items were classified into 3 categories through EFA: altering the center of gravity (9 items), basic functional activity (8 items), and progressive basic functional activity (4 items). Convergence and discrimination validity of the measurement model for all 3 factors were established through CFA. The total scores of the new functional evaluation tool for aquatic performance showed a strong correlation with the MBI score (r = 0.636, p < 0.001) and correlated with the MRC sum score (r = 0.298, p = 0.01).
Conclusion
The new functional evaluation tool for aquatic performance presented herein has adequate validity with physical function on land, suggesting the possibility of using this tool for functional assessment during aquatic rehabilitation therapy. |
