OBJECTIVES: To examine the reliability and fall experience discrimination of the
Cross Step Moving on Four Spots Test (CSFT) and the relationship between CSFT and
fall-related physical function. DESIGN: The reliability of the CSFT was examined
in a test-retest format with the same tester. Fall history, fall risk, fear of
falling, activities of daily living (ADL), and various physical parameters were
measured for all participants. SETTING: A community center and university medical
school. PARTICIPANTS: Elderly community-dwelling subjects (N=533; 62 men, 471
women) aged 65 to 94 years living independently. INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: Time to complete all the CSFT steps required, fall risk
score, ADL score, and fall-related physical function (isometric muscle strength:
toe grip, plantar flexion, knee extension, hip flexion, hand grip; balance: 1-leg
standing time with eyes open, functional reach test using an elastic stick; and
gait: 10-m maximal walking speed). RESULTS: The trial-to-trial reliability test
indicated good reliability of the CSFT in both sexes (intraclass correlation
coefficient =.833 in men, .825 in women). However, trial-to-trial errors
increased with an increase in the CSFT values in both sexes. Significant
correlations were observed between the CSFT values and scores for most
fall-related physical function tests in both sexes. However, the correlation
coefficient for all significant correlations was <0.5. Two-way analysis of
variance (sex x fall experience) revealed that the fall experience is a
significant factor affecting CSFT values; values in fallers were significantly
lower than those in nonfallers. The odds ratios in logistic regression analysis
were significant in both sexes (men, 1.35; women, 1.48). As determined by the
Youden index, the optimal cutoff value for identifying fall experience was 7.32
seconds, with an area under the curve of .676. CONCLUSIONS: The CSFT can detect
fall experience and is useful in the evaluation of different fall-related
physical functions including muscle strength, balance, and mobility.
