The curvilinear relationship of physiological capacity to function is well established (Buchner & DeLateur, 1992). A threshold between function on the Continuous Scale Physical Functional Performance (CS-PFP) and maximal aerobic capacity and strength was identified as 57 CI: 48-59 (Cress & Meyer, 2003).
PURPOSE: To determine the functional performance of 3 levels of self-reported function: "limited a lot", "limited a little", "not limited at all".
METHODS: In a cross-sectional design, independent and retirement community residents were assessed on everyday household tasks (e.g carry groceries, climb stairs, pick up scarves, 6-min fast walking) of the CS-PFP test that produces scores ranging from 0-100 with threshold values listed above. SF36 physical function scale has 10 questions with 3 level responses as listed above. An ANOVA was used to determine CS-PFP total score mean differences among the 3 levels with a Duncan post hoc analysis.
RESULTS: Older adults (n=186) age 77.2± 7.2; range 60-97, volunteered. Table 1: CS-PFP score (CS-PFP Units) for each response to selected SF36 Physical Function Questions. p<.05 *different from other two categories; # different from each of the other categories. Self-reporting "limited a lot" was reflected by CS-PFP total scores below the threshold and significantly below the other categories. "Limited a little" was generally within the confidence interval of the threshold whereas "not limited at all" reporting was higher than actual capability.
CONCLUSION: Older adults perceived a gradient of limitation that was consistent with functional performance. Recognition of functional limitation may be an important prerequisite for behavioral change to improve function.
