Predictors for response to rehabilitation in XXXX with hip or knee osteoarthritis: a comparison of logistic regression models with three different definitions of responder.

@entity1 @entity308 @entity571 @entity6372 @entity922
OBJECTIVE: To identify pre-treatment predictors of who will benefit from a 3-4-week comprehensive rehabilitation intervention in @entity1 with @entity571 ( @entity571 ) of the knee or hip. METHODS: A prospective cohort study with assessments at admission to the clinic and after 6 months was conducted. Two hundred and fifty @entity1 from the rehabilitation clinic Rehaclinic Zurzach, Switzerland, were included. Three different measures of response to a 3-4-week comprehensive rehabilitation intervention were used: one indirect measure ( @entity922 ( @entity922 ) in the Western Ontario and McMaster Universities @entity571 Index (WOMAC) global score=18% improvement), one direct measure (transition question) and a combination of both criteria. Responders were predicted by a sequential logistic regression analysis with nine personal variables, five lifestyle risk factors, seven psychological status variables and the WOMAC global baseline score. RESULTS: The set of statistically significant predictors was dependent on the definition of response. The comparison of predictors that were statistically significant in any of the prediction models showed similar odds ratios (ORs) for the majority of predictors across three regression models with the @entity6372 as dependent variable. Female gender, absence of @entity308 ( @entity308 ), history of complementary medicine (cm) and low comorbidity (com) were the most stable predictors and had ORs above 2.0 (female) and above 1.5 ( @entity308 , cm, com) across the three regression models with @entity6372 . CONCLUSION: A set of predictors for the outcome of rehabilitation in @entity1 with @entity571 was identified. If these predictors could be confirmed in future research, this knowledge might help to adopt and individualize the treatment of @entity1 who are, at present, less likely to respond.
