Carrying angle of the human elbow joint
Journal of Orthopaedic Research, 1983AbstractPrevious elbow kinematic studies have created some controversy because of conflicting and contradictory results. The lack of consistent results may be traced to the limitations and definitions of the specific measurement techniques, as well as individual variations in the specimens.

Joint angle signaling by muscle spindle receptors
Brain Research, 1986Nerve 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 ...

As frequently noted in the literature on robotics (Sugihara et al. 2002; Kurazume et al. 2003; Vukobratovic et al. 2007; Kwon and Park 2009) and mechanisms (Duffy 1978; Chaudhary and Saha 2007), a higher Degrees-of-Freedom (DOF) joint, say, a universal, a cylindrical or a spherical joint, can be represented using a combination of several intersecting 1-

Specificity of joint angle in isometric training
European Journal of Applied Physiology and Occupational Physiology, 1989Six healthy women (21.8 +/- 0.4 y) did isometric strength training of the left plantarflexors at an ankle joint angle of 90 degrees. Training sessions, done 3 times per week for 6 weeks, consisted of 2 sets of ten 5 s maximal voluntary contractions. Prior to and following the training, and in random order, voluntary and evoked isometric contraction ...

Ambulatory measurement of 3D knee joint angle
Journal of Biomechanics, 2008Three-dimensional measurement of joint motion is a promising tool for clinical evaluation and therapeutic treatment comparisons. Although many devices exist for joints kinematics assessment, there is a need for a system that could be used in routine practice. Such a system should be accurate, ambulatory, and easy to use.

Procedural considerations for photographic based joint angle measurements
Gait & Posture, 2005Measuring static joint angles is important to clinicians involved in assessing, diagnosing and treating musculoskeletal disorders. New measurement techniques such as the Uillinn Method (UM) employ the relatively new technology of digital photography and software to form a virtual goniometer.

Integrity of Small Angle Mitered Joints
Volume 2: Pipeline Safety Management Systems; Project Management, Design, Construction and Environmental Issues; Strain Based Design; Risk and Reliability; Northern Offshore and Production Pipelines, 2016Miter bends are permitted for use in the oil and gas industry in a variety of configurations. This paper addresses small angle miter joints used to correct minor misalignments. The CSA Z662-15 standard (Oil and Gas Pipeline Systems) states in the construction section (Clause 6.2.3(g)) that “mitred bends shall not be used”.

Awareness of knee joint angle under static conditions
Journal of Neurophysiology, 1975The ability of subjects to match the angle of a passively positioned knee joint by active positioning of the opposite leg is nearly constant with time from 15s to 3 min. However, their ability to match this angle from memory is equally good. Thus, knowledge of joint angle after movement has ceased does not necessarily require ongoing input from tonic ...

Globographic visualisation of three dimensional joint angles
Journal of Biomechanics, 2011Three different methods for describing three dimensional joint angles are commonly used in biomechanics. The joint coordinate system and Cardan/Euler angles are conceptually quite different but are known to represent the same underlying mathematics.

Upper limb joint angle tracking with inertial sensors
2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011Wearable inertial systems have recently been used to track human movement in and outside of the laboratory. Continuous monitoring of human movement can provide valuable information relevant to individual's level of physical activity and functional ability.
