Torque was measured at 5 different angular positions between 0° (arm along the trunk) and 120° in both directions. The torque-angle curves were approximated with polynomial of the second order. The abduction torque-angle curve has a shape of hyperbola with maximum at 0° and adduction ...
Arm abduction occurs when the arm moves away from the midline of the body, as when flapping the arms like a bird. Arm adduction happens when the arm moves toward the midline of the body, as when flapping the arms like a bird. Circumduction is the circular movement of the arm about the...
After the calibration, the headset was temporarily taken off and data were collected with the purpose of computing the range of motion of each DOF (shoulder flexion/extension (S-FE), shoulder abduction/adduction (S-AA), humeral rotation (H-R), elbow flexion/extension (E-FE), forearm pronati...
and lowest for shoulder extension, abduction, and external rotation [away from body; R = 16.30(6.62); L = 13.00(6.98)]. We also report baseline muscle performance for the 23 patients who completed baseline fitness testing (including 7 missing post-intervention measures) in Supplemental...

Active joints feature the shoulder adduction–abduction (sAA), shoul- der flexion–extension (sFE), shoulder internal–external rotation (sIEr) and elbow flexion–extension (eFE). Being the zero-configuration with the arm laying parallel to the trunk, the four active joints present the following ...
4 Other biomechanical factors, such as shoulder abduction angle at stride foot contact, peak shoulder horizontal adduction angular velocity, elbow angle at the instant of peak valgus stress, peak shoulder external rotation torque, progressive lateralization of release point, and internal rotation range ...
The mallet can be moved left and right using horizontal shoulder abduction and adduction; the entire movement range covers 25 degrees in the ARMin’s shoulder joint. By default, the center of the 25-degree range corresponds to the arm pointing straight forward, though the center of the range ...
Physiologically these axes translate to elbow medial/lateral rotation, elbow flexion/extension, shoulder flexion/ extension, elbow pronation/supination, wrist flexion-extension, and wrist adduction/abduction. they heard the experimenter say "Stop". Participants were then asked to assume the starting ...
