In Dupuytren's contracture, the palmar fascia within the hand becomes abnormally thick, which can cause the fingers to curl and can impair finger function. The main function of the palmar fascia is to increase grip strength; thus, over time, Dupuytren's contracture decreases a person's ability to hold objects and use the hand in many different ...
Alien hand movement in the posterior variant may show a typical posture, sometimes referred to as a "parietal hand" or the "instinctive avoidance reaction" (a term introduced by neurologist Derek Denny-Brown as an inverse form of the "magnetic apraxia" seen in the frontal variant, as noted above), in which the digits move into a highly extended ...

[8] Jamming of the finger induces a rupture of the extensor tendon or a broken bone at the tendon's site of attachment. [9] This results in a droopy and crooked appearance of the end joint of the finger, resembling a ...
[1] [2] Overcontraction of affected muscles, cocontraction of agonist and antagonist pairs, and activation of muscles inappropriate to a task all impair use of the affected hand. [3] Writer's cramp is a task-specific focal dystonia of the hand. [4] 'Focal' refers to the symptoms being limited to one location (the hand in this case), and 'task ...
