Thus, we argue that both precuneus as well as the IFG may reflect conflicts of agency in unconscious and unwanted movements. However, other explanations may also account for the activation of the right IFG. [journals.plos.org]

The mildest form of the syndrome is caused by damage to the brain’s parietal and/or occipital lobe, causing a hand to unconsciously avoid contact with objects by “levitating” with its fingers extended. [damninteresting.com]

Clinical signs and symptoms included right hemiparesis, hemianesthesia, dysphagia, language and cognitive dysfunction, personification and autonomous movement of the affected limb; involuntary grasping of objects interfered with his activities of daily [tandfonline.com]

Of these two disturbances, the former is better termed “somatoparaphrenia” ( Joynt and Goldstein 1975 ) or “asomatognosia” ( Thomas et al 1998 ) and is usually associated with hemianesthesia. [medlink.com]

Alien hand syndrome has been reported to be associated with several abnormal involuntary movements when different regions of the brain, like the corpus callosum, parietal region, or frontal region, are involved. [ncbi.nlm.nih.gov]

Thus, "alien hand" has been extended to include non-goal-directed, involuntary tonic posturing ( Bundick and Spinella 2000 ; Inzelberg et al 2000 ; Sabrie et al 2015 ), even though the patient may not indicate any sort of alien quality ( Ball et al 1993 [medlink.com]

The affected hand is not weak but maintains normal strength, and the hand movements are not spastic or convulsive. [ptproductsonline.com]
