1. Health care is a human right. 2. The care of the individual is at the center of health care, but the whole system needs to work to improve the health of populations. 3. The health care system must treat illness, alleviate suffering and disability, and promote health. 4. Cooperation with each other, those served, and those in other sectors is essential for all who work in health care. 5. All who provide health care must work to improve it. 6. Do no harm.

Is this a practical approach

Foot plantar pressure is the pressure field that acts between the foot and the support surface during everyday locomotor activities. Information derived from such pressure measures is important in gait and posture research for diagnosing lower limb problems, footwear design, sport biomechanics, injury prevention and other applications. This paper reviews foot plantar sensors characteristics as reported in the literature in addition to foot plantar pressure measurement systems applied to a variety of research problems. Strengths and limitations of current systems are discussed and a wireless foot plantar pressure system is proposed suitable for measuring high pressure distributions under the foot with high accuracy and reliability. The novel system is based on highly linear pressure sensors with no hysteresis.

The purpose of this study was to determine accurately the magnitude and changes of intra-cycle velocity fluctuation (Vfluc), maximum (Vmax) and minimum velocity (Vmin) of the center of mass during a maximum 200 m frontcrawl swim, and to examine whether they are associated with performance. Performance was indicated by the mean velocity (Vmean) of the stroke cycle (SC) in the swimming direction. The relative Vfluc, Vmax and Vmin were also calculated as a percentage of Vmean, while Vfluc was calculated for all three directions. Eleven male swimmers of national/international level participated in this study and their performance was recorded with four below- and two above-water-synchronized cameras. Four SCs were analyzed for the 200 m swim (one for each 50 m). Anthropometric data were calculated by the elliptical zone method. Vmean generally decreased throughout the test. Vmax and Vmin were positively correlated to performance and were significantly higher in SC1 than in the other SCs. However, the relative Vmax and Vmin values were remarkably consistent during the 200 m and not associated with performance. Despite the noteworthy magnitude of Vfluc in all directions, they were in general not correlated with performance and there were no significant changes during the test.

Three-dimensional analysis of intracycle velocity fluctuations in frontcrawl swimming.

Aim Footwear interventions are used within clinical practice in an effort to reduce ulcerations however the effectiveness of these interventions is unclear. The aim of this paper was to conduct a systematic review which examined the effectiveness of footwear as an intervention for prevention of diabetic foot ulcers or the reduction of biomechanical risk factors for ulceration and to discuss the quality and interpret the findings of research to date. Methods The CINAHL, Medline and Cochrane Register of Controlled Trials databases were searched with 12 articles identified for review. Results The majority of these studies were cross sectional and examined the effect of different footwear conditions on plantar pressure measurements. Factors which influenced study findings such as participant selection, measurement and analysis techniques, footwear design and compliance are discussed and recommendations for future studies are provided. Conclusions No research to date has examined the effectiveness of footwear in preventing ulceration. Conflicting findings are reported on the effective of footwear interventions to prevent reulceration. While the use of rocker sole footwear and custom orthoses in plantar pressure reduction are supported in cross sectional studies, longitudinal studies are required to confirm their benefit.
