Resonating Reflex A Critical Investigation Of The Physical An... by John Rudd

At critical reflection levels, based on King and Kitchener, physiotherapists’ judgements were at levels four to seven.Ĭonclusions: The results showed that physiotherapists critically justified their clinical reasoning by systemically using a hypothetico-deductive reasoning model and reflected on their decisions in all phases of low back pain patient’s examination, from the history to the physiotherapy diagnosis and also on the classification of non-specific low back pain. They stopped to consider the adequacy of tests for drawing conclusions and their own manual skills as physiotherapists and also the classification of LBP being used. Results: Physiotherapists critically analysed and reflected their choices and decisions in clinical reasoning with patient’s symptoms, onset of pain, clinical test choices and results. Interviews were audio-recorded and transcribed and then analysed by content analysis. Method: Data were collected in interviews with six physiotherapists, were the stimulated recall method was used.

Statistically reliable data are presented which indicate that the performance of critical visual tasks, such as reading, produces certain reflex effects which may be regarded as important criteria for revealing the expenditure of human energy in seeing.

A higher order model is also proposed, and its advantages and drawbacks are discussed. Through these tests, some other numerical specificities of the SPH method are discussed, such as the self-redistribution of the particles occurring during the Lagrangian evolution. The convergence of our model is heuristically proved on these nonlinear prototype tests, showing at the same time the very satisfactory level of accuracy reached. On the shown test problems, it is also evidenced that some numerical tools are crucial to ensure the robustness and accuracy of the standard SPH method. The role of numerical errors in the development of acoustic frequencies in the pressure signals is discussed, as well as the influence of the choice of the sound velocity. In particular, a great care is paid to the dynamic part of the solution, which is critical to the local hydrodynamic load prediction. The present work aims at investigating various numerical aspects of this method, often little mentioned in literature. These rather critical prototype problems shall constitute suitable test cases to get through when building a free-surface SPH model.

In this paper, an in-depth study of SPH method, in its original weakly compressible version, is achieved on dedicated 2D and 3D free-surface flow test cases.
