Programme Grants for Applied Research programmeThe Programme Grants for Applied Research (PGfAR) programme, part of the National Institute for Health Research (NIHR), was set up in 2006 to produce independent research findings that will have practical application for the benefit of patients and the NHS in the relatively near future. The Programme is managed by the NIHR Central Commissioning Facility (CCF) with strategic input from the Programme Director.The programme is a national response mode funding scheme that aims to provide evidence to improve health outcomes in England through promotion of health, prevention of ill health, and optimal disease management (including safety and quality), with particular emphasis on conditions causing significant disease burden.For more information about the PGfAR programme please visit the website: http://www.nihr.ac.uk/funding/programme-grants-forapplied-research.htm This reportThe research reported in this issue of the journal was funded by PGfAR as project number RP-PG-0407-10070. The contractual start date was in December 2008. The final report began editorial review in September 2014 and was accepted for publication in August 2015. As the funder, the PGfAR programme agreed the research questions and study designs in advance with the investigators. The authors have been wholly responsible for all data collection, analysis and interpretation, and for writing up their work. The PGfAR editors and production house have tried to ensure the accurac...

“…These patients were tested before the procedure and 3, 6, 12, and 24 months thereafter. This study [6] showed a clear trend to improvement, with an average extent of effect after 24 months (mean improvement) of 0.7 (when expressed in preoperative SD of TKA patients) or 1.5 (SD of the healthy group). Such responsiveness is satisfactory.…”

“…The raw signals are stored in a portable recorder and are analyzed with special software which extracts movement features. All signal properties are derived from the original accelerometer signals, while several movement features are calculated in terms of angle, duration (time), frequency, or a dimensionless number [6].…”

“…In a previous study [6] 140 persons with knee problems (most of them diagnosed with osteoarthritis of the knee while waiting for TKA) and 32 matched persons without knee pain underwent a Dynaport knee test. The results of this study showed that the majority of item X movement feature combination discriminated significantly between the healthy subjects and TKA patients.…”

Function studies after total knee arthroplasty (TKA) generally use either self-reported instruments or objective quantitative measurements of walking activities, but it is unclear how objective factors influence self-reports. This retrospective multicenter study assessed the impact of objective variables on subjective self-reported functional outcome after TKA in 128 patients at a mean of 41 months after TKA. Self-reported disability was measured by the Western Ontario and McMaster University (WOMAC) scale, and the quality of walking and representative daily activities were determined objectively by the DynaPort knee test. Objective assessment was found to be a poor predictor of WOMAC abnormality, with correlations of 0.343, 0.246, and 0.269 with WOMAC function, stiffness, and pain, respectively. The results of WOMAC are thus strongly influenced by factors other than quantitative parameters of the lower extremity. These findings provide support for including an objective assessment of activities of daily living together with a subjective self-report.

“…As corresponding and first authors of the article on objective measurement of functional abilities in knee patients [5], we thank Ejnar Eriksson [1] for his editorial reaction. We agree with many points, but contrary to Eriksson's implicit suggestion, we do not think that the DynaPort KneeTest is a competitor to kinematic analysis in the gait laboratory since the KneeTest aims at another level of analysis.…”
