The Relationship between Vitamin D and Physical Performances or Functional Capacities for the Musculoskeletal Ambulation Disability Symptom Complex Female Patients.

Abstract

[Purpose] The purpose of this study was to examine any relationship between vitamin D and physical performances or functional capacities for the musculoskeletal ambulation disabilitysymptom complex (MADS) female patients. [Method] The serum level of vitamin D was measured. The physical and functional tests were performed: pain scale, knee extension strength, one leg standing time (OLS), Timed Up and Go test (TUG), Berg Balance Scale (BBS), 10 m minimum walking time (MWT) and Tokyo Metropolitan Institute of Gerontology (TMIG) Index of Competence). We evaluated the relationship between vitamin D and physical performances or functional capacities using single and multiple regression analysis. [Results] Single regression reveals that significant correlations were observed between vitamin D and knee extension strength, OLS, BBS and MWT. Multiple regression analysis reveals that vitamin D and BBS significantly contributed to OLS and that BBS and MWT significantly contributed to TUG. [Conclusion] It was suggested that vitamin D would be useful indicator of physical performance for MADS female patients.
