Cash noted that "the elbow angle has changed over the years on Djokovic's serve.
The kinetic effects of the pins placement and elbow angle on concentric distraction and mobilization were also discussed.
In addition, the ideally concentric distraction might occur only at an elbow angle of 120° owing to the ulnar anatomy.
The posture adopted by the subjects consisted of the bent forearm with elbow angle of 90° and neutral wrist position, as described in the ISO 10819 standard.
However, the patient is usually in this large brace for 4-8 wks and the elbow angle, for extension, is gradually increased.
Furthermore, those two prerequisite are interactive and sensitive to elbow angle, fixator design, and pin placement of the bridged elbow-pin-fixator construct.
The method requires only three simple measurements: (i) horizontal position of the hand (x0); (ii) vertical displacement of the barbell (Z) and (iii) elbow angle.
The posture angles were shoulder flexion of 60°, 90° and 120° combined with an included elbow angle of 90°, 120° and 150°, respectively.
These variables include stride length, trunk angle, elbow angle and height of elbow above shoulder, the timing of the actions (e.g., Did the players stride? Did hip rotation and shoulder rotation follow a smooth sequence?) and so on.
Four of these indices (all except elbow angle) were significantly higher (p < 0.05) in VE than in RE, which indicates that subjects experienced more discomfort and grew fatigued more quickly in VE.
Results: The elbow angle with the participant's hand at the top dead center position of the pushrim ranged from an average of 55.1°±6.4° of flexion in the highest seat position to 76.9°±4.5° in the lowest.
