Results show that the movements were mainly abduction and adduction, simple opening and closing, and did not seem to involve propulsion or retropulsion, forward and backward movements. In this review, we discuss the chemical nature of ACR and how this determines the corresponding sites of protein adduction.īut it also controls the adduction of the vocal folds. It is particularly useful in bedridden patients who have thigh adduction constraints, to facilitate hygiene. Slow components of the adductor muscle permit sustained adduction, while the interlocking hinge teeth prevent shear. One popular theory postulates that a clubfoot is a result of intrauterine maldevelopment of the talus that leads to adduction and plantarflexion of the foot. Normal hip range of motion includes abduction, adduction, circumduction, extension, and flexion. It is once this position is attained that the prime movers of adduction vigorously contract against the resistance of the water. Irregular adduction can be superimposed on a fixed reduction of the glottic area caused by tonic adduction of the vocal cords. The action of adduction along the frontal plane of the body will cause the arm to be moved in a curvilinear arc. This deformity presents as adduction of the little toe with some external rotation of the digit.Īrytenoid adduction and rotation is another technique that seeks to medialize the vocal process of the paralyzed arytenoid cartilage.
