Measurements of normal joint angles by goniometry in calves

Veterinary and Comparative Orthopaedics and Traumatology, 2014
SummaryThe aim of this study was to establish normal reference values of the forelimb and hindlimb joint angles in normal Holstein calves.Thirty clinically normal Holstein calves that were free of any detectable musculoskeletal abnormalities were included in the study.

Dependence of human ankle compliance on joint angle

Journal of Biomechanics, 1978
Abstract The compliance of the normal human ankle joint has been measured at different mean joint angles. This was done by applying band-limited Gaussian torques to rotate the ankle about a horizontal axis through the medial malleolus. The dependence of the measured compliance on mean joint angle is found to be primarily due to passive properties of

Soft curvature sensors for joint angle proprioception

2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011
We introduce a curvature sensor composed of a thin, transparent elastomer film (polydimethylsiloxane, PDMS) embedded with a microchannel of conductive liquid (eutectic Gallium Indium, eGaIn) and a sensing element. Bending the sensor exerts pressure on the embedded microchannel via the sensing element.

The effects of joint angle on electromyographic indices of fatigue

European Journal of Applied Physiology and Occupational Physiology, 1996
The purpose of this study was to examine the effect of manipulation of joint angle on electromyographic (EMG) fatigue curves at different sites over the quadriceps muscle group. Eight subjects performed isometric knee extensions at 0.26, 0.79, and 1.31 rad from full extension for 1 min at 50% of maximum.

Joint angle signaling by muscle spindle receptors

Brain Research, 1986
Nerve impulses were recorded from sensory fibers supplying the tibialis anterior and soleus muscles of anesthetized cats as the ankle joint was moved from one end of the flexion-extension axis to the other and back again in steps of 6-7 degrees. The rate of movement from one position to the next was 40 deg/s and each position was held for 16-18 s ...

The effects of joint angle and reliability on knee proprioception

Medicine & Science in Sports & Exercise, 2001
The purpose of this study was to examine the reliability and effects of knee angle on the detection and subsequent response to passive knee movement.Twenty college-aged male and 20 female volunteers were evaluated for proprioception by a newly developed perturbation test.

Radiographic measurement of tibial joint angles in sheep

Veterinary and Comparative Orthopaedics and Traumatology, 2009
SummaryThe aim of this study was to establish normal reference values of anatomic and mechanical joint angles of the tibia in sheep at different age groups. Eighteen clinically healthy Santa Ines sheep were used. The animals were divided into three equal groups according to age: Group I – from six- to eight-months-old, Group II – 2-years-old, Group III

Joint Angles Similarities and HOG2 for Action Recognition

2013 IEEE Conference on Computer Vision and Pattern Recognition Workshops, 2013
We propose a set of features derived from skeleton tracking of the human body and depth maps for the purpose of action recognition. The descriptors proposed are easy to implement, produce relatively small-sized feature sets, and the multi-class classification scheme is fast and suitable for real-time applications.

Relationship of Metatarsophalangeal Joint Fusion on the Intermetatarsal Angle

Foot & Ankle, 1989
To evaluate the effect of fusion of the first metatarsophalangeal joint on the first intermetatarsal angle, a series of 62 consecutive first metatarsophalangeal fusions was reviewed. Of these, 47 had sufficient data to be included in this study. The results of this study showed that the change in the first intermetatarsal angle following a first ...

Accuracy Improvement on the Measurement of Human-Joint Angles

IEEE Journal of Biomedical and Health Informatics, 2016
A measurement technique that decreases the root mean square error (RMSE) of measurements of human-joint angles using a personal wireless sensor network is reported. Its operation is based on virtual rotations of wireless sensors worn by the user, and it focuses on the arm, whose position is measured on 5 degree of freedom (DOF).
