title: [Association of confidence in motor function and fear of falling with physical ability in community-dwelling older people].
abstract: OBJECTIVE
  The objective of this study was to investigate the difference of physical ability depending on the presence or absence of confidence in motor function (CIMF) and fear of falling (FOF) in independently living community-dwelling older adults.
  
  
  METHODS
  Participants in this study were 368 community-dwelling older adults (mean age±SD, 72.2±5.7 years) without instrumental activity of daily living (IADL) problems who participated in a comprehensive health check-up. CIMF (existence or non-existence), FOF (existence or non-existence), past medical history, history of a fall within the past year, and self-rated health were assessed by interview. Physical ability [grip strength, one-leg standing (OLS), maximum walking speed (MWS), and timed up & go test (TUG)] was also measured.
  
  
  RESULTS
  Our results revealed significantly more older adults with FOF and without CIMF than expected, indicating that CIMF might be a component factor in FOF. Two-way ANOVA adjusted for sex and age showed main effects of the CIMF factor on grip strength, OLS, and TUG, indicating that these physical abilities are reduced in participants without CIMF, regardless of FOF. On the other hand, we found a main effect of the FOF factor on MWS. Logistic regression analysis showed that frequency of going outdoors, self-rated health, arthropathy, and OLS were factors associated with CIMF.
  
  
  CONCLUSIONS
  Our results suggest that CIMF is a useful screening tool for older adults with potential problems and evaluation of intervention for health promotion in community-dwelling older adults without IADL problems.
