purpose: regarding the high prevalence of low back pain in various communities and the need to determine an appropriate treatment plan for these patients, examining their functional limitation and disability level is of utmost importance. in this regard, one of the important indicators is lumbar range of motion. measurement of the range of motion is a common and appropriate method for determini...

OBJECTIVE To determine whether there are differences in results when evaluating cervical range of motion (ROM) with radiographic analysis, a bubble goniometer, and a dual inclinometer and whether particular physical parameters are related to cervical ROM. METHODS We evaluated the cervical ROM of 115 volunteers with each of the 3 clinical methods. Tape measurements of neck girth, distance from...

Objective. This study aimed to describe the interrater and intrarater reliability of the flexicurve index, flexicurve angle, and manual inclinometer in swimmers. A secondary objective was to determine the level of agreement between the inclinometer angle and the flexicurve angle and to provide an equation to approximate one angle from the other. Methods. Thirty swimmers participated. Thoracic k...

This paper describes a novel measurement method to accurately measure the rotating shaft tilt angle of rotating machine for alignment or compensation using a dual-axis inclinometer. A model of the rotating shaft tilt angle measurement is established using a dual-axis inclinometer based on the designed mechanical structure, and the calculation equation between the rotating shaft tilt angle and t...

STUDY DESIGN This study examines the reliability and validity of measuring lumbar range of motion with an inclinometer. OBJECTIVES To find out whether a manual determination of the reference points for measuring lumbar range of motion is as reliable as radiologic determination for positioning the inclinometers, lumbar range of motion was determined in degrees by evaluating radiographs and by ...

This paper presents numerical simulation results of an airflow inclinometer with sensitivity studies and thermal optimization of the printed circuit board (PCB) layout for an airflow inclinometer based on a genetic algorithm (GA). Due to the working principle of the gas sensor, the changes of the ambient temperature may cause dramatic voltage drifts of sensors. Therefore, eliminating the influe...

In this paper, the inclinometer is used to control the balance of a humanoid robot on a miniature surfboard. GHR (Griffith University Humanoid Robot) is the humanoid robot developed in the Robotics and Games laboratory, at Griffith University. In order to measure the angle of the inclining surfboard, the inclinometer is attached to the back of the right foot of the GHR. To remove the high frequ...

Inclinometer assembly error is one of the key factors affecting the measurement accuracy of photoelectric measurement systems. In order to solve the problem of the lack of complete attitude information in the measurement system, this paper proposes a new inclinometer assembly error calibration and horizontal image correction method utilizing plumb lines in the scenario. Based on the principle t...

The paper presents a device devoted to detect and measure earth displacements produced by landslides. It is part of inclinometer type geotechnical instruments and is based on measuring the deformation produced to a rod vertically mounted into the ground during soil layers sliding. With respect to other commercial devices, our inclinometer is characterized by high sensitivity to very small defor...
