Automated feet detection for clinical gait assessment.

The paper describes a computer vision method for estimating the clinical gait metrics of walking patients in unconstrained environments. The method employs background subtraction to produce a silhouette of the subject and a randomized decision forest to detect their feet. Given the feet detections, the stride and step length, cadence, and walking speed are estimated.

Lower limb pose estimation for monitoring the kicking patterns of infants.

Monitoring the spontaneous kicking patterns of infants can give insight into their development. A computer vision based method for estimating the pose of an infant's leg from range images is presented in this paper. After some manual inputs for initialization, the range data associated with the infant is extracted.

Modulation of orthogonal body waves enables high maneuverability in sidewinding locomotion.

Many organisms move using traveling waves of body undulation, and most work has focused on single-plane undulations in fluids. Less attention has been paid to multiplane undulations, which are particularly important in terrestrial environments where vertical undulations can regulate substrate contact. A seemingly complex mode of snake locomotion, sidewinding, can be described by the superposition of two waves: horizontal and vertical body waves with a phase difference of ± 90°.

Analyzing the outcomes of health promotion practices.

This article focuses on health promotion (HP) outcomes, illustrated through evaluation of case studies and identification of strategies which have contributed to their success and sustainability. Evaluation research and practice in three distinct sceneries are discussed: (i) institutional and governmental agencies; (ii) communities in the "Manguinhos Complex" and Nova Iguaqu Municipality, and (iii) building of potentially healthy municipality networks. The effectiveness of a social program in a health promotion perspective was based in the "School for Parents" program, undertaken by the First Court of Childhood and Youth of Rio de Janeiro, between 2001 and 2004.

[Integrating prevention and promotion in health systems: four realities, diverse similarities].

The Forum Dialogue on national health systems which took place as a satellite meeting of the 2nd International Conference on Local and Regional Health Programmes compared four countries (Brazil, France, Switzerland and Canada) sustain "conditions to integrate prevention and promotion in health systems". Despite the diversity of the four systems presented, several similarities regarding difficulties faced and achievements obtained in the integration process have been extracted, which has allowed highlighting three perspectives of action. It is suggested that prevention and promotion can be integrated into health systems by mobilising the population and health professionals towards prevention, but with the condition that the promotion and prevention sector increase its credibility by developing practices of quality, organisation, discourse, and prevention practices adjusted to the health care context.
