Dependence of human ankle compliance on joint angle
Journal of Biomechanics, 1978Abstract 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

Wearable Monitoring of Joint Angle and Muscle Activity
2019 IEEE 16th International Conference on Rehabilitation Robotics (ICORR), 2019Simultaneous tracking of muscle activity and joint rotation is of significant interest in rehabilitation, but gold-standard methods with optical motion tracking and wireless electromyography recording typically restricts this to the laboratory setting.

Radiographic measurement of tibial joint angles in sheep
Veterinary and Comparative Orthopaedics and Traumatology, 2009SummaryThe 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

Upper limb joint angle measurement in occupational health
Computer Methods in Biomechanics and Biomedical Engineering, 2015Usual human motion capture systems are designed to work in controlled laboratory conditions. For occupational health, instruments that can measure during normal daily life are essential, as the evaluation of the workers' movements is a key factor to reduce employee injury- and illness-related costs.

Three DOF wrist joint - control of joint stiffness and angle-
2010 IEEE International Symposium on Industrial Electronics, 2010A mechanism of three DOF joint similar to human wrist joint is introduced in this paper. It fundamentally mimics the human muscro-skeletal system to control not only its joint angle but also its joint stiffness. The key mechanism is the originally developed ANLES (Actuator with Non-Linear Elasticity System) that can be used as a voluntary muscle.

Knee and ankle joint torque–angle relationships of multi-joint leg extension
Journal of Biomechanics, 2011The force-length-relation (F-l-r) is an important property of skeletal muscle to characterise its function, whereas for in vivo human muscles, torque-angle relationships (T-a-r) represent the maximum muscular capacity as a function of joint angle. However, since in vivo force/torque-length data is only available for rotational single-joint movements ...

Joint Angle-Based Skeleton Action Recognition
Human action recognition is a difficult task and topic of discussion in the computer vision community. There are consistent breakthroughs by large research groups using sophisticated state-of-the-art computation hardware. These advancements allow for very accurate predictions on complex action recognition datasets that can be generalized to tasks ...openaire +1 more source
