Scuderi G et al had used apraclonidine topically and observed that post-operative IOP was significantly reduced compared to oral acetazolamide or placebo.9 Mjahed et al studied effect of lidocaine and clonidine combination in retrobulbar anaesthesia and concluded that it can decrease post injection IOP and can enhance sedation and analgesia and akinesia.10 In one comparative study of clonidine and lidocaine by Nunes et al, it was concluded that oral clonidine prevented post- endotracheal intubation induced IOP rises, more effectively than lidocaine.11 Kumar et al found that oral clonidine (300 g) as premedication could decrease IOP rises after retrobulbar injection.12
Right ventricular function in adults with repaired tetralogy of Fallot assessed with cardiovascular magnetic resonance imaging: detrimental role of right ventricular outflow aneurysms or akinesia and adverse right-to-left ventricular interaction.
Akinesia is a symptom pertaining to bradykinesia (slowness of movement) and muscle stiffness or rigidity.[4] The classic pill-rolling rest tremor associated with IPD is noted when the hand is motionless.
Furthermore, our patient exhibited apical ballooning, which is typical for takotsubo cardiomyopathy and not with hypo- or akinesia of the anterior wall and of the apex, which would rather be typical for spasm of the LAD.
The stepping test, which assesses forelimb akinesia, was essentially performed as described by Olsson et al.
Repeat injection of 2-3ml will be given at inferotemporal margin for patients who do not develop adequate akinesia and analgesia.
Echocardiography showed akinesia of anterior and apical segments and ejection fraction was 25%.
This mechanism may be responsible for akinesia and rigidity.
It has been proposed that, in the spectrum of dopamine-dependent symptoms, apathy is a neuropsychiatric correlate of the motor symptom akinesia, impulse control disorder, a nonmotor counterpart of dyskinesia [3].
On general physical and neurological evaluation, she presented extrapyramidal rigidity, bradykinesia and some periods of akinesia. There was no rest or postural tremor, but the speech was slurred, very difficult to be understood.
It typically affects elderly individuals producing muscle rigidity, akinesia and tremor.
