To overcome the problem new definitions are proposed for the true flexion/extension and abduction/adduction angles as two independent parameters for three-dimensional joint rotation.īenati, M., Gaglio, S., Morasso, P., Tagliasco, V., and Zaccaria, R. Abductive reasoning, or abduction, is making a probable conclusion from what you know. NAUTILUS INSPIRATION Abduction/Adduction Model IPAA4 Right/Left range of motion adjustment handle beneath seat Rotating thigh pads for inner/outer thigh. Therefore, two-dimensional measurements of flexion/extension and abduction/adduction can be erroneous and overestimated for a three-dimensional joint rotation. Abduction and adduction refer to movements made about a sagittal axis and along the coronal plane. Although the error can be less than 2 o for flexion below 20 o when the initial abduction angle is at 30 o, it can be as large as 9 o for 60 o of flexion with an initial 10 o of abduction nearly double the real abduction angle. The results indicate that for an out-of-plane flexion the error in abduction angle measured by previous methods increases with both flexion and initial abduction angle and become very sensitive when the flexion angle exceeds 40 o. A quantitative error analysis is presented to show how large an error can be produced in the flexion/extension and abduction/adduction angles when using two-dimensional measurements to represent three-dimensional joint rotations. Whether these traditional two-dimensional measurements represent true joint rotations in three dimensions has not been investigated. These two-dimensional definitions have been used extensively in the biomechanical literature for reporting and representing both two-dimensional and three-dimensional joint rotations. ![]() Flexion/extension and abduction/adduction, two major parameters for the description of joint rotations, are used to define planer anatomical orientations of body segments. Adduction exercises involve moving your limbs toward the midline, while abduction exercises entail moving your limbs away from the midline, she explains.
