Wireless Motion Sensors-Useful in Assessing the Effectiveness of Physiotherapeutic Methods Used in Patients with Knee Osteoarthritis-Preliminary Report.

Osteoarthritis of the knee (OAK) is characterized by pain, limitation of joint mobility, and significant deterioration of proprioception resulting in functional decline. This study assessed proprioception in OAK patients following two ten-day rehabilitation programs using the Orthyo system. Fifty-four study participants with clinical symptoms and radiological signs of OAK were randomly divided into an exercise group ( = 27) or a manual therapy group ( = 27).

Measurement of the growth of children at weekly intervals.

A new method for measuring the growth of children is presented, based on the measurement of the lower leg length during foot movement. This is a touch measurement, but the obtained characteristic of the measured lower leg length, as a function of the pressure force, is reduced to a non-contact measurement. A setup prototype is built and preliminary research conducted.

Accuracy of X-ray computed tomography for dimensional metrology with employment of a new threshold selection method.

The article presents and discusses results of an experimental study regarding the accuracy of measurements performed with X-ray CT scanners. One of the main factors affecting the measurement result is definition of the threshold value between the air and the material. In this study, the results of measurements using two methods to determine the threshold value namely, the newly developed method and a well-known and commonly used method of ISO50%, were compared.

Hierarchical, Three-Dimensional Measurement System for Crime Scene Scanning.

We present a new generation of three-dimensional (3D) measuring systems, developed for the process of crime scene documentation. This measuring system facilitates the preparation of more insightful, complete, and objective documentation for crime scenes. Our system reflects the actual requirements for hierarchical documentation, and it consists of three independent 3D scanners: a laser scanner for overall measurements, a situational structured light scanner for more minute measurements, and a detailed structured light scanner for the most detailed parts of tscene.
