It is possible that a group of patients respond best to MDT and have larger effects. Iden- tification of patients who respond best to MDT compared to other interventions would be an important finding. Purpose: To identify possible predictors to response to the McKenzie therapy in patients with chronic low back pain. Methods: Secondary analysis from a previous trial com- paring MDT to back school in 148 patients with chronic LBP. Only patients classified at baseline assessment as being in the derangement group were included. To reduce the chance of spurious findings we limited the number of predictors and hypothesised the direction of effect for each potential effect modifier. The predictors tested were 1. Clear centralisation vs directional preference only; 2. Baseline pain location; 3. Baseline pain intensity; and 4. Age. The primary outcomes for this study were pain inten- sity (NPRS) and disability (RMDQ) at the end of treatment (4 weeks). Treatment effect modification was evaluated by assessing the group versus predictor interaction terms from linear regression models. Results: The presence of clear centralization, pain located below the knee and older age did not predict a more favourable response to MDT. High pain intensity at baseline seems to be a clinically useful effect modifier for disability, but not for pain improvement. Conclusion(s): Our hypothesis setting study suggests high pain intensity may be an important treatment effect modifier for patients with chronic LBP receiving MDT. The results of this secondary analysis have to be interpreted cau- tiously and replication is required. Implications: Identification of patients who respond best to MDT compared to other interventions and identify possible predictors, which can influence in this clinical response, would be an important finding for the evidence and clinical practice.

The effects of dual sensory impairment are greater than the effects of vision and hearing problems alone due to the lack of compensatory and regulatory mechanisms involved in the execution of daily tasks. Purpose: To investigate the prevalence of dual sensory loss and the its association with disability and participation restriction. Methods: Cross-sectional exploratory population-based study derived from a FIBRA network study (Frailty in Brazil- ian Older Adults) including older adults aged 65 years and older, both women and men. Visual and hearing loss was eval- uated asking the participants if they listen and see well. They were classified in two groups: No sensory impairment and one sensory impairment (Non-DSI group) and dual sensory impairment (DSI group). Disability in basic activities of daily living (BADL) was assessed through Katz scale and disabil- ity in instrumental activities of daily living (IADL) through Lawton scale. For both variables the median was ascertained
