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 ...
Stiff-person syndrome (SPS), also known as stiff-man syndrome, [1] is a rare neurological disorder of unclear cause characterized by progressive muscular rigidity and stiffness. The stiffness primarily affects the truncal muscles and is characterised by spasms , resulting in postural deformities.
Chest wall. Wooden chest syndrome is a rigidity of the chest following the administration of high doses of opioids during anesthesia [1]. Wooden chest syndrome describes marked muscle rigidity — especially involving the thoracic and abdominal muscles — that is an occasional adverse effect associated with the intravenous administration of lipophilic synthetic opioids such as fentanyl.

Respiratory arrest is a serious medical condition caused by apnea or respiratory dysfunction severe enough that it will not sustain the body (such as agonal breathing). Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest.
Stone heart syndrome (also known as ischemic myocardial contracture) is a rare and severe condition characterized by extreme rigidity and hardness of the heart muscle.This condition typically occurs during high-risk situations such as heart surgery or following a severe heart attack, often leading to life-threatening complications.
Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, [1] [2] spasmophilia, [3] [4] [5] latent tetany, [4] [5] and central neuronal hyper excitability syndrome (NHS), [3] is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly ...
A workout in cold temperatures can also induce chills quickly, especially when you push hard and then stop. Active muscles produce heat, but once you stop exercising, that heat dissipates and can ...
Central hypoventilation syndrome (CHS) is a sleep-related breathing disorder that causes ineffective breathing, apnea, or respiratory arrest during sleep (and during wakefulness in severe cases). CHS can either be congenital (CCHS) or acquired (ACHS) later in life.
