Introduction: Hip and knee osteoarthritis are associated with functional limitations, pain and restrictions in quality of life and the ability to work. Furthermore, with growing prevalence, osteoarthritis is increasingly causing (in)direct costs. Guidelines recommend exercise therapy and education as primary treatment strategies. Available options for treatment based on physical activity promotion and lifestyle change are often insufficiently provided and used. In addition, the quality of current exercise programmes often does not meet the changing care needs of older people with comorbidities and exercise adherence is a challenge beyond personal physiotherapy. The main objective of this study is to investigate the short- and long-term (cost-)effectiveness of the SmArt-E programme in people with hip and/or knee osteoarthritis in terms of pain and physical functioning compared to usual care. Methods: This study is designed as a multicentre randomized controlled trial with a target sample size of 330 patients. The intervention is based on the e-Exercise intervention from the Netherlands, consists of a training and education programme and is conducted as a blended care intervention over 12 months. We use an app to support independent training and the development of self-management skills. The primary and secondary hypotheses are that participants in the SmArt-E intervention will have less pain (numerical rating scale) and better physical functioning (Hip Disability and Osteoarthritis Outcome Score, Knee Injury and Osteoarthritis Outcome Score) compared to participants in the usual care group after 12 and 3 months. Other secondary outcomes are based on domains of the Osteoarthritis Research Society International (OARSI). The study will be accompanied by a process evaluation. Discussion: After a positive evaluation, SmArt-E can be offered in usual care, flexibly addressing different care situations. The desired sustainability and the support of the participants' behavioural change are initiated via the app through audio-visual contact with their physiotherapists. Furthermore, the app supports the repetition and consolidation of learned training and educational content. For people with osteoarthritis, the new form of care with proven effectiveness can lead to a reduction in underuse and misuse of care as well as contribute to a reduction in (in)direct costs.

Het doel van deze systematische review is het evalueren van de meest effectieve fysiotherapeutische behandelingen gericht op loopfunctie, kwaliteit van leven, range of motion en spierkracht na een totale knieprothese op basis van artrose, die gepubliceerd zijn na 2007. Voor dit onderzoek zijn acht RCT’s geïncludeerd. De uitkomsten van deze onderzoeken versterken het al eerder aangetoonde voordeel van fysiotherapie op korte termijn na een totale knieprothese.
Background: The modified painDETECT questionnaire (PDQ) is a self-reported questionnaire to discriminatebetween nociceptive and neuropathic-like pain in patients with knee/hip osteoarthritis (OA). This studyaims to assess the structural and construct validity of this questionnaire.Methods: Confirmatory factor analysis and hypothesis-testing was used. For 168 patients, predefinedhypotheses were formulated on the correlation between the modified painDETECT and several otherquestionnaires, and in a subsample of 46 with pain pressure thresholds (PPTs).Results: Two principal components were confirmed. The pain pattern item did not load on any component.Eighty per cent of the hypotheses on the correlation between modified PDQ and the questionnaireswere met, as were 50% concerning PPTs measurements.Conclusions: This study is the first to assess structural and construct validity of the modified PDQ knee/hip by using factor analysis and hypothesis-testing. This questionnaire seems to reflect neuropathic-like pain symptoms experienced by hip/knee OA-patients with adequate validity. The item on pain patternmight not reflect the construct. More than 75% of the predefined hypotheses regarding the modified PDQ and the other questionnaires were met. Only 50% of the hypotheses on PPTs measurements were met, probably due to heterogeneity and limited size of this subsample.
