Spastic hypertonia involves uncontrollable muscle spasms, stiffening or straightening out of muscles, shock-like contractions of all or part of a group of muscles, and abnormal muscle tone. It is seen in disorders such as cerebral palsy, stroke, and spinal cord injury. Rigidity is a severe state of hypertonia where muscle resistance occurs ...
In many people with SPS, muscle rigidity eventually progresses from the trunk to the limbs — first affecting muscles closest to the trunk, then further. [6] Stiffened limbs can affect a person's balance and gait, causing awkward 'statue-like' falls, where the affected person cannot put out their arms to soften the impact. [6]
Cadaveric spasm can be distinguished from rigor mortis as the former is a stronger stiffening of the muscles that cannot be easily undone, while rigor mortis can. [ 2 ] The cause is unknown but is usually associated with violent deaths under extreme physical circumstances with intense emotion , such as the circumstances associated with death ...
Spasticity can be differentiated from rigidity with the help of simple clinical examination, as rigidity is a uniform increase in the tone of agonist and antagonist muscles which is not related to the velocity at which the movement is performed passively and remains the same throughout the range of movement while spasticity is a velocity ...
Dyskinesia can be anything from a slight tremor of the hands to an uncontrollable movement of the upper body or lower extremities. Discoordination can also occur internally especially with the respiratory muscles and it often goes unrecognized. [3] Dyskinesia is a symptom of several medical disorders that are distinguished by their underlying ...
Its symptoms include pain, tingling, numbness and muscle weakness. The symptoms affect just one particular part of the body, depending on which nerve is affected. The diagnosis is largely clinical and can be confirmed with diagnostic nerve blocks. Occasionally imaging and electrophysiology studies aid in the diagnosis. Timely diagnosis is ...
Unfortunately, arm injuries, carpal tunnel and wrist arthritis are all incredibly common. A recent study found that over a ten-year period, an average of 2.6 million people with wrist injuries ...
It is typically symmetrical, and affects the arms, hands, or fingers; but sometimes involves the head, vocal cords, or other body parts. [4] Essential tremor is either an action (intention) tremor—it intensifies when one tries to use the affected muscles during voluntary movements such as eating and writing—or it is a postural tremor, which ...
