Understanding acoustic events and monitoring their occurrence is a useful aspect of many research projects. In particular, acoustic goniometry allows researchers to determine the source of an event based solely on the sound it produces. The vast majority of acoustic goniometry research projects used custom hardware targeted to the specific application under test. Unfortunately, due to the wide ...

To achieve more objective and repeatable measurements of equinus contracture, we developed the equinometer, a device that allows the measurement of ankle range of motion under controlled torque conditions. This study assessed its accuracy across different subjects and examiners. Two examiners used the equinometer to measure the angle of ankle dorsiflexion at 15 N x m torque on five subjects. Ac...

Clinicians assess wrist and hand function to identify pathology, monitor effectiveness of treatment, and determine the readiness to return to work and other activities. The goniometer, the conventional evaluation tool used to assess range of motion (ROM), is most suited to the measurement of passive and active joint ROM under conditions that entail static, nonfunctional movements. Instruments t...

The aim of this study was to assess the reliability of a smartphone-based application developed for photographic-based goniometry, DrGoniometer (DrG), by comparing its measurement of the knee joint angle with that made by a universal goniometer (UG). Joint goniometry is a common mode of clinical assessment used in many disciplines, in particular in rehabilitation. One validated method is photog...

In this paper, a laboratory goniometer system for performing multi-angular measurements under controlled illumination conditions is described. A commercially available robotic arm enables the acquisition of a large number of measurements over the full hemisphere within a short time span making it much faster than other goniometers. In addition, the presented set-up enables assessment of anisotr...

Objectives. The aim of this study is to introduce a new way and assign its reliability and validity in measuring the angle of hallux valgus. Methods. In this method, we have proceeded to introduce a simple way for measuring the angle of hallux valgus by using ruler and mathematical formulas. For doing this study, we selected 25students and measured their angle of hallux valgus with new way ...

We report a new method for directly monitoring dynamic surface wetting that occurs during electrochemical droplet cell corrosion measurements on an Al alloy and Cu galvanic couple. The combination of goniometer potentiostat enabled the in situ observation wettability polarization each metal at interface two metals 0.4 ?L NaCl aqueous droplets. Droplet spreading was heterogeneously metals, where...
