Causes Of Cogwheel Rigidity
Typically if muscles in the cervical and lumbar
regions are injured they will go into spasm
to protect themselves from further injury
this will create the rigidity that the writer
The symptoms can be helped with moist
heat, muscle relaxants and physical
therapy modalities. ...Read more
Meningitis: High fever, severe headache that isn't easily confused with other types of headache, stiff neck, vomiting or nausea with headache, confusion or difficulty concentrating — in the very young, this may appear as inability to maintain eye contact, seizures, sleepiness or difficulty waking up, sensitivity to light, lack of interest in drinking and eating, skin rash in some cases, such as in viral kind. ...Read more
Does serotonin cause muscular rigidity via its effects in the central nervous system or by binding to peripheral 5-ht receptors in the body?
Centrally: Overstimulation of primarily the 5-ht2a receptors seems the leading hypothesis currently. ...Read more
Someone past smoker developed parkinson with rigidity, fluid build up on left lung, are lungs affected by rigidity of back shoulder? To causes atstass
Fluid on lungs: Lungs should not be generally affected by Parkinson's disease or rigidity. Fluids on lungs could be due to many cardiac and lung disorders and should be evaluated thoroughly. ...Read more
Kernicterus causes spasticity? Why is it sis basal ganglia considered in pyramidal tract? Why not causing rigidity instead like parkinsons?
Spasticity: Basal ganglia and substantia nigra are different structures. Injuring the basal ganglia, such as by stroke, may cause spasticity. Injuring the substantia nigra may cause parkinsons symptoms, such as tremor and rigidity. Rigidity and spasticity are not the same, as you recognize. These two different structures of the brain modulate movement differently, that is why the symptoms are different. ...Read more
Taking dopamine caused me muscle rigidity and an inability to move. Then took abilify (aripiprazole) and akineton and was getting worse. Stoped them and walked better?
That's a good -: -statement that is followed by a question mark. That in and of itself does not make it a question. ...Read more
If I have an overdriven sympathetic nervous system (manifesting in tachycardia &restlessness) would that be a cause of my muscle rigidity? Sooo tight
Possibly: Your system is in a high strung state and could cause muscle tightness and tension. I assume you have had endocrinology testing to rule out hyperthyroidism, pheochromocytoma, etc. If so, perhaps a stress management program would effectively treat your symptoms best and you have been recommended to avoid alcohol, caffeine and nicotine. Your physician would know best whether beta blockers would help. ...Read more
Spasticity is an increased resistance to the passive movement of a joint due to abnormally high muscle tone, and varies with the amplitude and speed of the joint motion. Seen after a stroke.
Rigidity is an increased resistance to the passive movement of a joint which is constant throughout the range of joint motion, and not related to the speed of joint movement. Seen in Parkinson's disease. ...Read more
See below: It is mostly the quality of the movement. With rigidity, the muscle tone stays pretty much the same when someone moves the limb, there is constant resistance to movement. It has also been called "lead pipe" rigidity. In spasticity, there is initial resistance to movement and then the resistance gives way. This is called "clasp-knife" spasticity. Rigidity is often seen in parkinsons. ...Read more
Rigidity: Rigidity is an abnormality of muscle tone that can occur in certain neurological conditions. It is a resistance to movement. An example of this is Parkinson's disease which can cause rigidity. That is not the only condition that can cause rigidity though. ...Read more
Does this help?: 'cogwheel' rigidity and 'leadpipe' rigidity are two types identified with parkinson's disease. 'leadpipe' rigidity results when an increase in muscle tone causes a sustained resistance to passive movement throughout the whole range of motion, with no fluctuations.'cogwheel' rigidity is a combination of leadpipe rigidity and tremor which presents as a jerky resistance to passive movement. ...Read more
None: Not quite sure what you mean by muscle wall rigidity, muscles do not have "walls". They are made of bundles of muscle fibers and the bundles are encased in strong elastic tissue called fascia. They have to increase in diameter as they contract, and then relax back to the original shape as they lengthen. A rigid wall would prevent shape changes. Swollen muscles can feel like there's a rigid wall. ...Read more
This is abnormal: Rigidity is an involuntary response to an injury or other abnormal situation. Muscle tone or firmness is a different situation. You can develop muscle tone and firmness by working muscles as with exercise. ...Read more
The skeletal system.: The bones of the skeletal system provide the structure and rigidity. Crustaceans in the seas, however, are soft on the inside and have outer shells to provide this same structure and rigidity. ...Read more
Muscle rigidity: Muscle rigidity = muscle is unable to relax properly due to increased tension or stiffness. ...Read more
Catatonic rigidity: Catatonic rigidity occurs when a person remains in very stiff & immobile postures. If you move a persons' limb who has catatonic rigidity it will likely remain in that position. It can be seen in catatonic Schizophrenia and some times with mood disorders. ...Read more
Stiffness: If muscle is stiff or tight, then you have it. ...Read more
It doesn't.: It's just more noticeable since walking is a much more complex and dangerous activity. ...Read more
