Developing Patient-Centered Preventative Care to Reduce Mobility Disability With Aging: Preferences From a Discrete Choice Experiment.

BACKGROUND AND PURPOSE: Mobility disability is the most prevalent form of disability for older adults in the United States. A physical therapy mobility checkup (MC) under development is a patient-centered preventative physical therapy visit. It includes physical performance testing and education on physical performance as a valuable and modifiable health indicator. The purpose of this study was to identify the proportion of older adults willing to participate in an MC, the age at which they would initiate care, their desired frequency of participation, and the characteristics, or attributes, of the MC they preferred. METHODS: In a cross-sectional study conducted at the Minnesota State Fair, adults older than 55 years answered survey questions about preventative health practices and completed a discrete choice experiment (DCE) to determine their preferences for the MC. Attributes studied in the DCE were visit duration, checkup content, education, and possible outcomes of participating in preventative care for mobility. Descriptive statistics characterized demographic information and survey responses. Conjoint choice modeling estimated the main effect for each DCE attribute. RESULTS AND DISCUSSION: One hundred sixty-six older adults participated in the study. Seventy-eight percent indicated that they would choose an MC if available. Most participants (66%) believed that MCs should occur before 60 years of age and at least annually (68%). A 30-minute visit duration, which accounted for 84% of attribute importance, was preferred. Balance, the preferred content of the MC, accounted for 12% of the attribute importance. Preferences for educational content and possible outcomes of participation with preventative care aimed at preventing mobility loss were not statistically significant. CONCLUSION: Older adults value preventative care for reducing mobility disability. They identified time efficiency and the inclusion of measures to assess balance as priorities for this preventative physical therapy visit.

Performance and Clinimetric Properties of the Timed Up From Floor Test Completed by Apparently Healthy Community-Dwelling Older Women.

BACKGROUND AND PURPOSE: Standing up from the floor is a demanding mobility activity with important implications. The purpose of this study was to describe performance and the clinimetric properties of the Timed Up From Floor (TUFF) test completed by apparently healthy community-dwelling older women. METHODS: In this observational and methodological quality study, 52 community-dwelling women, 55 years and older, were examined. Convergent and discriminant validities were examined by analyzing the correlations of TUFF test times with other mobility variables and emotional status, respectively. Validity was further examined by comparing TUFF times between age groups and fall risk groups. Interrater reliability of the TUFF test was established by comparing the times obtained by 3 raters observing the same videotaped performances. Test-retest reliability was determined by having the same 3 raters observe videos of the same participants performing the TUFF test during a second session 1 week later. RESULTS: The grand mean (SD) TUFF time measured by all testers on the first day was 5.8 (2.9) seconds. Convergent validity was demonstrated by significant negative (P < .001) Spearman correlations between the TUFF test and the Physical Functioning Scale of the 36-Item Short Form Health Survey (SF-36) (-0.69), usual gait speed (-0.48), fast gait speed (-0.74), and the 30-second sit-to-stand test (-0.46). Discriminant validity was indicated by a low and nonsignificant correlation (0.17) between the TUFF test and the SF-36 Emotional Well-being Scale. Known-groups validity was supported by a significant difference in the TUFF test times of 2 age groups (P = .02) and 2 fall risk groups (P < .001). The TUFF test was determined to have excellent relative interrater reliability (intraclass correlation coefficient [ICC] of 0.99) and absolute reliability (minimal detectable change [MDC95%] of 0.8 seconds). Relative test-retest reliability was excellent with ICCs of 0.88 to 0.92. Corresponding MDC95% values were large (2.4-2.8 seconds and 40.7%-45.9%). CONCLUSIONS: The TUFF test is an informative, reliable, and valid tool suitable for documenting mobility limitations in independent community-dwelling older women. More information regarding responsiveness is required.
