چکیده
The determination of the instantaneous axis of rotation of human joints has numerous applications. The screw axis can be determined using optical motion capture systems or electromechanical goniometers. In this paper, we introduce a new method for the localization of the instantaneous screw axis in human anatomical joints from the data given by a spatial mechanical goniometer.

Experimental Evaluation of a Goniometer For the Identification of Anatomical Joint Motions
This paper exposes the experimental evaluation of a new technique for the estimation of the instantaneous helical axis of movement of human anatomical joints. The measurement technique, using a six degrees of freedom spatial electro-goniometer, is tested onto a simple revolute joint and onto a subject’s knee. A motion capture system with active optical markers is used at the same time in order ...
متن کاملThe comparison of spinal curves and hip and ankle range of motions between old and young persons
Background :Falls have been strongly associated with decreased physical activity and impaired mobility. Reduced range of motion, as a consequence of muscle stiffness, has been indicated to assume a positive relationship to fall incidence. Also clinical observations suggest that maintaining the normal spinal curves is associated with the prevention of spinal, knee and hip disorders. Thus, the ...
متن کاملSmartphone and Universal Goniometer for Measurement of Elbow Joint Motions: A Comparative Study
BACKGROUND Universal goniometer (UG) is commonly used as a standard method to evaluate range of motion (ROM) as part of joint motions. It has some restrictions, such as involvement of both hands of the physician, leads to instability of hands and error. Nowadays smartphones usage has been increasing due to its easy application. OBJECTIVES The study was designed to compare the smartphone incli...
متن کاملVerification of selected anatomical landmarks used as reference points for universal goniometer positioning during elbow joint mobility range measurements.
The paper presents the results of comparative studies on the range of active elbow joint motion based on data obtained from 50 physical education students. The measurements were made with both an electrogoniometer and a manual goniometer. An explanation of differences in measurement results has been provided based on an investigation by the photographic method of 3 elbow joints using cadaveric ...
متن کاملPermeability estimation from the joint use of stoneley wave velocity and support vector machine neural networks: a case study of the Cheshmeh Khush Field, South Iran
Accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.Acoustic method can be used as analternative and effective tool for permeability determination. In this study, a four-step approach is proposed for permeability estimati...
