In most cases, there is bilateral improvement following a unilateral lesion, although contralateral improvement is greater.[25,11,18] Homonymous hemianopsia is the most emphasized complication,[25] because of the close proximity of the pallidal lesions to the optic tract, but its incidence has been reduced by improved stereotactic techniques.[18] Optimum candidates for VP are those with akinesia partially responsive to medication, bradykinesia with freezing during repetition, asymmetrical severe rigidity, or frequent disabling dyskinesia.[11,18]
The operation is effective in relieving the symptoms of rigidity, akinesia and tremor in 75% of patients undergoing unilateral lesion placement.[6] Improvement is noted immediately following surgery with a significant reduction in the debilitating side effects associated with PD.
The following items were used as explanatory variables: MMSE, disease duration, Hoehn-Yahr scale, history of falls, UPDRS3 total score, and individual items of UPDRS3 (tremor: 20,21; rigidity: 22; diadochokinesis: 23-26; posture: 28, 30; walking: 29; and akinesia: 31).
Akinesia of the gallbladder is to be seriously considered after total vagectomy operation.
A FOG episode can manifest with step size reduction (shuffling gait), knee trembling, or akinesia and is typically described as feeling the feet as frozen or glued to the ground [100].
Finally, in a 6-OHDA animal model of PD, researchers examined the effects of psychological stress on biological mechanisms involving DA and norepinephrine that may contribute to motor symptom outcomes of akinesia [61].
The causative factors leading to fetal akinesia are supposed to be many and can be classified as, extrinsic--where there is insufficient space in uterus for normal fetal movements, like abnormal shape of uterus, fetal crowding or insufficient amniotic fluid and intrinsic--muscular, neurological, or connective tissue disorder in the fetus.
Table V Akinesia was graded on a scale designed to measure ocular movement in each quadrant.
These procedures revealed a distal spontaneous coronary artery dissection of the left anterior descending (LAD) branch of the left coronary artery, a non-dilated left ventricle with apical akinesia and an apical filling defect suggestive of a left ventricular apical thrombus.
Motor symptoms show four basic features: tremor, rigidity, akinesia (or bradykinesia), and postural instability (4).
The 2D Echocardiographic evaluation done within 24 hours of acute STEMI showed regional wall motion abnormality suggestive of anterior wall ischaemia in the form of hypokinesia (80.95%) and akinesia (11.90%) in patients with acute AWMI.
