another name for muscle rigidity that often occurs in death is what
Cadaveric spasm, also known as postmortem spasm, instantaneous rigor, cataleptic rigidity, or instantaneous rigidity, is a rare form of muscular stiffening that occurs at the moment of death, persists into the period of rigor mortis and can be mistaken for rigor mortis.adaveric spasm, also known as postmortem spasm, instantaneous rigor, cataleptic rigidity, or instantaneous rigidity, is a rare form of muscular stiffening that occurs at the moment of death, persists into the period of rigor mortis and can be mistaken for rigor mortis. Sometimes, stiffness can occur due to muscle disuse (or minimal use) from decreased conditioning. Rigidity of the back muscles is a common experience for many people after back injuries. Muscle rigidity is often seen in Parkinson's disease (a type of brain disease resulting in motor impairments).In Parkinson s disease, rigidity often occurs initially in the shoulder, along with pain. Axial rigidity can also occur on Parkinson s disease, which is rigidity of the neck and trunk.This can cause the spine to curve and/or a stooped over posture, which causes further rigidity.here Medical Information is Easy to Understand™. Rigidity means hardness, inflexibility, or stiffness. Rigidity occurs due to increased tone (tension) in muscles near a joint that are in a shortened state (known as agonist muscles) and muscles that work to oppose such shortening (known as antagonist muscles).

The following symptoms can occur In Parkinson's disease. Which of these symptoms that do occur vary from person to person, over time, and in their severity Muscular symptoms Tremor: Tremor can occur in the fingers, hands, arms, legs, chin, tongue, lips, eyelids, and the head.t can do this via the enzyme peroxidase, instead of the enzyme tyrosinase, which Is usually responsible for melanin production, which does not occur in the dopaminergic neurons. OTHER DISORDERS There are other medical disorders that often occur simultaneously with Parkinson's Disease. Sleep problems are a feature of the disease and can be worsened by medications. Symptoms can manifest as daytime drowsiness, disturbances in REM sleep, or insomnia. A systematic review shows that sleep attacks occur in 13.0% of patients with Parkinson's disease on dopaminergic medications.arkinson's disease is more common in older people, with most cases occurring after the age of 50; when it is seen in young adults, it is called young onset PD (YOPD). The main motor symptoms are collectively called parkinsonism, or a parkinsonian syndrome. The disease can be either primary or secondary. The motor symptoms of Parkinson's disease result from the death of dopamine-generating cells in the substantia nigra, a region of the midbrain. The causes of this cell death are poorly understood.arkinson's disease is more common in older people, with most cases occurring after the age of 50; when it is seen in young adults, it is called young onset PD (YOPD).

Muscle rigidity is an alteration of muscle tone in which the muscles are in an involuntary state of continual tension. Muscle rigidity can be a manifestation of neurological damage (basal ganglia diseases) or a side effect of certain medications.etanus is a serious bacterial infection that affects the nervous system and causes muscles to tighten. Commonly called lockjaw, it primarily causes muscle contractions in the jaw and neck. It can be life-threatening.
