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 ...
The muscle damage is most usually caused by a crush injury, strenuous exercise, medications, or a substance use disorder. [3] Other causes include infections, electrical injury, heat stroke, prolonged immobilization, lack of blood flow to a limb, or snake bites [3] as well as intense or prolonged exercise, particularly in hot conditions.

Rigid spine syndrome, also known as congenital muscular dystrophy with rigidity of the spine (CMARS), is a rare and often debilitating neuromuscular disorder. It is characterized by progressive muscle stiffness and rigidity, particularly in the spine, which can severely limit mobility and impact quality of life. This condition is typically ...
Progressive encephalomyelitis with rigidity and myoclonus (PERM) [4] Muscle stiffness and contraction can cause abnormal resting postures. Around 70% of those with SPS have the "classic" form of the disease. [5] People with classic SPS typically first experience intermittent tightness or aching in the muscles of the trunk. [6]
