Lumbosacral Joint Angles in Children
Journal of Pediatric Orthopaedics, 1991We wished to determine values for the lumbosacral angles in children without spondylolisthesis. Eleven angles were measured on 112 consecutive standing lateral radiographs of children ranging in age from 3 to 18 years. Gender and scoliosis affected only sacral roll and the lumbosacral angle, respectively.

Kinematics of complex joint angles in robotics
Proceedings., IEEE International Conference on Robotics and Automation, 2002A method for using complex numbers in the kinematic solution of robotic manipulators is presented. The inverse kinematics algorithm of a manipulator produces complex joint angles if it is given an end effector location outside its workspace. Although complex joint angles cannot be implemented physically, they can be converted to real numbers through a ...

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 ...

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.
