Trend of the carrying angle during flexion-extension of the elbow joint: a pilot study.
This study evaluated the variability of the carrying angle during flexion-extension of the elbow and defined a description of the movement applicable in sport and rehabilitation.The arm and forearm of 7 healthy volunteers were marked and the coordinates were acquired during motion using 6 infrared cameras. Five repeated measures were performed for each volunteer to verify the reliability.Our results demonstrated that this movement can be easily modeled as a linear variation of the carrying angle in function of the flexion angle.The reliability between repeated measures was high and adopting a linear fit the accuracy was >94%.
