This document describes assessment of human physiological systems. Various noninvasive sensors can be used to detect vitals and other parameters and combined with mathematical models to assess the functional state of physiological systems. Conventional techniques can use invasive sensors to monitor cardiac pressures and volumes, along with pressure transit to quantify cardiovascular health. While known to be effective these invasive techniques often require surgery and are resource intensive limiting their use to cases where the risks and costs are of clear immediate benefit. In contrast, noninvasive health monitors present little if any risk and are easy to use. Further, the techniques described herein can determine trends in a person's cardiovascular health. With these trends, a person can know if the effort they expend to improve heart health actually makes a difference. Further, negative trends can be found that can spur people to improve their health or get medical attention.

A tactile device for correcting biomechanical abnormalities using physical virtual reality simulations includes an outer hollow sphere, a pliable inner hollow sphere, a plurality of actuators, and a framework. The plurality of actuators physically couple the outer hollow sphere to the pliable inner hollow sphere, and are configured to reshape the pliable inner hollow sphere as the outer hollow sphere and the pliable inner hollow sphere rotate. The framework includes a plurality of powered rollers which support the outer hollow sphere and control a rotational speed and direction of the outer and inner spheres. A set of pressure sensors detect pressure applied by a user against the pliable inner hollow sphere as the user moves within. One or more processors determine a biomechanical abnormality in the user based on pressure readings from the pressure sensors. A sphere controller then modifies a physical configuration of the pliable inner hollow sphere.

A method and apparatus for simulating, measuring and recording a subject's ability to perform a varying range of barrier reaches is provided. The apparatus includes a variable barrier reach instrument for simulating an actual barrier that the subject may lean against in performing a work task The variable barrier reach instrument may include a physical barrier having a substantially horizontal upper surface at a height above a base point. A sensing and recording device may be positioned proximate to the variable barrier reach instrument for sensing and recording a plurality of barrier reach data points as the subject bends forward against the physical barrier. A computer and an associated software program are also provided into which the recorded data points are entered. An algorithm may be contained within the software program that generates an interpolated arc reflecting the subject's reach at the physical barrier height from the recorded data points. Storage means associated with the computer are further provided for storing the interpolated arc and recorded data points.
