Objective The impact of osteoarthritis (OA, a common disorder with increasing prevalence) on peoples’ functional capacity is hardly known. Therefore the objective of this study was to evaluate the course of functional capacity of subjects in a prospective cohort study on early OA of hip and/or knee.
Methods Functional capacity of 94 subjects from the CHECK study (Cohort Hip and Cohort Knee) was measured at baseline, using a protocolled Functional Capacity Evaluation. Subjects were invited to participate in 1-, 2- and 5-year follow-up measurements. Descriptive data will be presented for these 4 measurements; later on data will be analysed with regression analysis or multilevel analysis.
Results The numbers of participants at the measurements at 0, 1, 2 and 5 year, were 93, 65, 57 and 29, respectively. Their mean age at baseline was 56 years and 61 at T5; 79-86% were females. There were no statistically significant differences between test performances at the 4 measurements. Overall means (SD’s) were: lifting low 19.9 (9.3) kg, lifting high 9.7 (5.2) kg, carry long 21.6 (11.1) kg, overhead static work 175 (79) sec, walking 337 (112) meters.
Discussion The functional capacity of the subjects remains more or less stable in 5 years. However, the number of participants decreased significantly with each measurement and the results have to be controlled for selective drop-out. The relation between functional capacity and other subject characteristics will be addressed. A point of discussion is the best way to analyse these results, for example with multi-level analysis.
