Abstract
This article reviews the concept of locomotor rehabilitation index (LRI) from the principle of dynamical similarities and the theory of mechanism minimizing the energy expenditure in pathological walking. This index is defined as the percentage ratio between self-selected speed and optimum speed (algebraically LRI = 100 × self-selected speed/optimum walking speed). First, we analyze the mechanical foundations of human walking especially focusing on general size effects. Then, we discuss the descriptive physiology of pendular mechanism, evidencing the path that leads to the view of reductionist and extremely descriptive view of pathological gait. Integrative models, generated by the first evidence presented in our previous papers around the LRI, represent a crucial change of perspective. This model is discussed in details and criticized concerning the ensuing experimental findings. Finally, we discuss the case of Parkinson's disease using the Nordic walking as a neat example of application of LRI on pathological locomotion. To conclude , the concept of LRI is reinforced by the substantial evidence, showing that this new proposal for assessing the gait functionality is extremely promising and should be stimulated in studies that examine the effects of therapies on gait functionality in degenerative diseases.
