TL;DR: The model provides a means to study the consequences of misalignment and insights for orthosis modification for improved comfort and can serve as an educational and training tool in prosthetics and orthotics courses for creating awareness about the importance of proper alignment of orthotic knee joints.
Abstract: ABSTRACT Introduction Pistoning is relative sliding motion between an affected limb and its corresponding externally fit assistive device (like an orthosis). Pistoning causes skin problems, pain, and discomfort to the orthosis user. Misalignment of an orthotic joint with respect to the anatomical joint is one of the causes of pistoning motion, and the current knowledge pertaining to the effects of orthotic knee center (OKC) misalignments in lower-limb orthoses is limited. This work quantifies the effects of OKC misalignment in terms of relative motion between the limb and the orthosis and predicts locations of resultant pressure point on the limb. Method A two-dimensional link segment model that simulates relative motion between the limb and orthosis was developed. The OKC was systematically misaligned in the anterior-posterior (A-P), proximal-distal (P-D) directions, and their combination to simulate orthosis/thigh strap sliding and identify pressure points on the thigh. Simulations were performed for stand-to-sit activity and walking with a knee-ankle-foot orthosis. Results It was found that OKC misalignment causes increased A-P and P-D relative motions with an increase in misalignment distance for the stand-to-sit activity. The A-P and P-D relative motions are of greater concern for activities involving increased knee flexion such as sitting, squatting, and kneeling as compared with walking with an orthosis. Although the A-P and P-D relative motions during walking are of small magnitude, they occur with reversals in the direction and are repetitive in nature, which may cause skin problems and discomfort due to recurring pressure points. Conclusions The model provides a means to study the consequences of misalignment and insights for orthosis modification for improved comfort. A software simulation tool based on the presented model can serve as an educational and training tool in prosthetics and orthotics courses for creating awareness about the importance of proper alignment of orthotic knee joints. Study of misalignments of this nature will also guide fabrication and fitting of lower-limb orthoses/exoskeletons.

TL;DR: This text encompasses the work of Dr Jacquelin Perry in her years as a therapist and surgeon focusing on the human gait, suitable for incorporating into many athletic training programmes, university physical therapy programmes and gait workshops.
Abstract: This text encompasses the work of Dr Jacquelin Perry in her years as a therapist and surgeon focusing on the human gait. The text is broken down into four sections: fundamentals; normal gait; pathological gait; and gait analysis systems. In addition to the descriptions of the gait functions, a representative group of clinical examples has been included to facilitate the interpretation of the identified gait deviations. The book includes detailed laboratory records with illustrations and photographs. Intended as a reference for health care professionals involved in musculoskeletal patient care, the text is suitable for incorporating into many athletic training programmes, university physical therapy programmes and gait workshops.

TL;DR: It is concluded that a given country cannot obtain the expected economic benefits from accelerated urbanization, especially if it takes the form of government-led urbanization.
Abstract: The relationship between urbanization and economic growth has been perplexing. In this paper, we identify the pattern of global change and the correlation of urbanization and economic growth, using cross-sectional, panel estimation and geographic information systems (GIS) methods. The analysis has been carried out on a global geographical scale, while the timescale of the study spans the last 30 years. The data shows that urbanization levels have changed substantially during these three decades. Empirical findings from cross-sectional data and panel data support the general notion of close links between urbanization levels and GDP per capita. However, we also present significant evidence that there is no correlation between urbanization speed and economic growth rate at the global level. Hence, we conclude that a given country cannot obtain the expected economic benefits from accelerated urbanization, especially if it takes the form of government-led urbanization. In addition, only when all facets are taken into consideration can we fully assess the urbanization process.
