What is clasp-knife deformity?
Enlarged downward projecting spinous process of L5 vertebra extending up to sacral vertebrae with associated bifida defects is known as “Clasp-knife deformity”. It is often the cause of backache particularly during bending movements and called “Clasp-knife syndrome”.
What does clasp-knife rigidity indicate?
clasp-knife rigidity increased tension in the extensor of a joint when it is passively flexed, giving way suddenly on exertion of further pressure; seen especially in upper motor neuron disease.
What is the other name of clasp-knife reflex?
Brain’s reflex extension of a hemiplegic flexed upper limb when a person is in a quadrupedal posture; called also quadrupedal extensor reflex.
Is clasp-knife reflex normal?
Clasp-knife response refers to a Golgi tendon reflex with a rapid decrease in resistance when attempting to flex a joint, usually during a neurological examination. It is one of the characteristic responses of an upper motor neuron lesion.
What is the cogwheel rigidity?
In cogwheel rigidity, your muscle will be stiff, like in other forms of rigidity. But you might also have tremors in the same muscle when it’s at rest. Cogwheel rigidity can affect any limb, but it’s most common in the arms. It can affect one or both arms.
What diseases do you see clasp-knife upper motor neuron rigidity and spasticity?
With upper motor neuron lesions the muscles, after an initial period of rigidity and resistance to movement, suddenly relax or give way, the so-called “clasp-knife” rigidity. Additionally, patients with Parkinson’s disease may show a cogwheel type of rigidity.
Is clasp knife spasticity or rigidity?
Clasp knife rigidity describes the phenomenon in a spastic limb where, after an initial resistance to passive movement of a joint, there is a sudden reduction in tone and the limb moves quite freely through the rest of the range of the particular movement.
Is clasp knife reflex normal?
What is Golgi tendon organ?
The Golgi tendon organ is a tree-like sensory ending enclosed in a spindle-like connective tissue capsule, that lies near the junction of a tendon with a muscle. In man, some 10 to 20 muscle fibres are connected to one tendon organ. A typical tendon organ in limb muscles has an ending of about 0.5 mm in length.

What is clasp knife rigidity?
What is clasp knife rigidity? Clasp knife rigidity describes the phenomenon in a spastic limb where, after an initial resistance to passive movement of a joint, there is a sudden reduction in tone and the limb moves quite freely through the rest of the range of the particular movement.
What is clasp knife spasticity?
Spastic dystonia is a muscle contraction that is present at rest, leading to a constant clinical posture that is highly sensitive to stretch. Clasp knife phenomenon: Limb initially resists movement and then suddenly gives way Stroking Effect: Stroking the surface of the antagonist muscle may reduce tone in spasticity.
Is this a British Army clasp knife?
This British Army issue clasp knife, produced in 1938, follows a standard pattern laid down in 1913. It incorporates and marlinspike and short can-opening blade, as well as a knife blade. It was superseded during the late 1930s by a model which featured a more modern can-opener. Has simple, ogival, can opener blade.
