Resistance to manipulation of a limb. Cogwheel rigidity, a characteristic of PD, occurs when rigidity is combined with tremor.
stiffness or inflexibility. Mental rigidity is an inflexibility in thinking.
Increase in muscle tone; results in greater resistance to passive movement. Resistance is felt as constant and uniform (lead-pipe rigidity), or a jerky "catches" (cogwheel rigidity).
"Involuntary contraction of the abdominal musculature [muscles]".
Rigidity is the force required to bend a strip of paper or board through a known angle. The instrument used is the Taber stiffness testing using an angle of 15°. The results are expressed in Taber stiffness tester units. The greater the value the more rigid the material.
hypertonia characterized by increased muscle tone; reflexes are not affected
Refers in medical usage to a type of muscular stiffness encountered when examining people with Parkinson's. It is characterised by a constant, even resistance to passive manipulation of the limbs.
the physical property of being stiff and resisting bending
inability to move any part of your body, despite the numerous attempts to do so; when rigidity is not so developed if any movements are possible at all, they are much more harder to perform than when being healthy
a material property: a rigid material is one that is resistant to changes in size or shape
The muscles feel stiff and there is resistance to movement even when another person tries to move the joint.
Stiffness in the muscles or resistance to movement.
An index of the resistance of an elastic body to shear. The ratio of the shearing stress to the amount of angular rotation it produces in a rock sample.
Guarding"Involuntary contraction of the abdominal musculature [muscles]". Also known as Guarding, this indicates pain or tenderness to the examining physician.
The degree of stiffness exibited by a flexible material which can adversely effect the material passing through the press and the labels passing through an applicator.
Progressive muscle stiffness
the name given to the special type of stiffness which is one of the main symptoms of Parkinson's. The muscle tend to pull against each other instead of working smoothly together. This is due to a failure of reciprocal relaxation of the antagonist muscles. There are two types: Cog wheel rigidity a term used to describe the type of intermittent resistance to movement found in Parkinson's Lead pipe rigidity a term used to describe the sustained resistance to movement found in Parkinson's and also cerebrovascular disease
Stiffness, resistance to bending.
increased resistance to the passive movement of a limb.
Stiffness in the limbs or body due to dysfunction of the basal ganglia and related structures.
Stiffness and resistance to movement. May be a symptom of a neurologic movement disorder such as Parkinson's disease. beginning of glossary
Loss of flexibility in thinking or movement.
If the limbs of a Parkinson's patient are moved passively, the muscles will often contract involuntarily, causing rigidity. This rigidity may be constant or intermittent. Intermittent rigidity is called cogwheel rigidity.
A tightness or even stiffness when moving the limb of a PD patient
abnormal stiffness of muscle.
Rigid muscles are stiff or tense, making them difficult to move.
Muscle tone is high and there is continuous contraction and resistance to passive movement
a symptom of the disease in which muscles feel stiff and display resistance to movement even when another person tries to move the affected part of the body, such as an arm.
An abnormal increase in the general tenseness of muscles that is not caused by anxiety or exercise.
Abnormal stiffness in a limb or other body part. It is most apparent when an examiner moves a patient's limb -- as in cogwheeling. Shy-Drager Syndrome (Multiple System Atrophy) A degenerative condition characterized by low blood pressure when standing. It may lead to parkinsonism, rigidity, ataxia, fainting, or incontinence.
a condition of hardness, stiffness, or inflexibility of a limb.
Stiffness or inflexibility, inability to bend.
Extremely high muscle tone in any position, combined with very limited movements.
A state of severe hypertonicity where a sustained muscle joint contraction does not allow for any movement at a specified joint.
The resistance to displacement under load in the elastic deformation region, dependent on bearing clearance and bearing type
