Development and Validation of a Method of Body Volume and Fat Mass Estimation Using Three-Dimensional Image Processing with a Mexican Sample.

Body composition assessment using instruments such as dual X-ray densitometry (DXA) can be complex and their use is often limited to research. This cross-sectional study aimed to develop and validate a densitometric method for fat mass (FM) estimation using 3D cameras. Using two such cameras, stereographic images, and a mesh reconstruction algorithm, 3D models were obtained.

[Correlation between gait speed and muscular strength with balance for reducing falls among elderly].

Background: Evidence of the benefit on propioceptive neuromuscular facilitation for reducing falls in older people does not exist.

Objective: The aim of this study is to evaluate the effects of propioceptive facilitation over falls and biomechanical variables, in comparison to standard treatment and control groups.

Materials And Methods: Series cases comparative for the 24 participants were recruited and randomnly assigned to 3 groups.
