| 释义 | flexion noun[ U ] medical specializeduk /ˈflek.ʃən/ us /ˈflek.ʃən/ the act of bending an arm, leg, etc. or of tightening a muscle: 活动（手臂、腿等）;绷紧（肌肉） After physiotherapy, the shoulder flexion significantly increased.物理治疗以后，肩膀的活动能力显著提高。 hip flexion髋关节屈曲 Bending, twisting and curving arch your back ball up bendy bent bowed distorted distortion entwine flex flexural swirling swirlingly swoopy tangle tangled wrap something around someone/something wriggle wristy writhe zigzag Examples of flexionflexion At this stage the precise location of the flexion point should be identified. For such locomotion limb with only two joints at hip and knee, an initial backward flexion will help to produce a suitable swing motion. Axial traction should be used, limiting the extent of lateral flexion of the head. A transoesophageal four chamber view,19 obtained with mild anterior flexion of the probe, was usually used. Simultaneous extension and flexion of fingers is one more feature in the representation than one of these movements in isolation. By rapidly accelerating the hip forward (flexion velocity and flexion moment), there is a positive power. All the plates had a thickness of 1.2 cm, large enough to avoid flexion at the pressures we used. Attenuation of the optic stalk occurred in the post-flexion stage coincident with a progressive rounding of the eye elliptical index of 0.61 6 0.06! An extensor muscle is used in the proportional position control of the digit flexion; the greater the tension the wider the hand opens. There were fixed flexion deformities of the interphalangeal joints of both thumbs and fifth fingers, and webbing between each thumb and the forefinger. Since the polycentric knee effectively moves the center of rotation posterior, an increased flexion moment (the extension stop) is expected. The idea behind this approach is making the fingers and thumb to behave as springs with a neutral position in full flexion. The angle of flexion of a whole finger with 3 joints was measured with a protractor. During swing a small but prolonged hip flexion moment is seen for the single-axis joint assumption model. Initial forward flexion, corresponding to a "heel-up" position if the shin comprises a foot, does not allow the biped to generate an adequate swing.
