Crepitus is "a grating sound or sensation produced by friction between bone and cartilage or the fractured parts of a bone". Various types of crepitus that can be heard in joint pathologies are: Bone crepitus: This can be heard when two fragments of a fracture are moved against each other.
Testing with median nerve SEPs is used to identify the sensory and motor cortex during craniotomies and in monitoring surgery at the midcervical or upper cervical levels. Posterior tibial nerve SEP monitoring is widely used for monitoring the spinal cord during scoliosis procedures and other surgical interventions in which the spinal cord is at ...
Researchers said on Wednesday they have settled the issue of what occurs inside knuckles to trigger the familiar popping sound. Snap, crackle, pop: study reveals secret behind knuckle-cracking ...
Quantitative vibratory testing can be used to assess a patient with myelopathy when the examiner detects uniform loss of vibration below a certain spinal level. For example, if the examination is normal from the iliac crest to the knees but pallesthesia is absent from the knees to the toes, this would be consistent with myelopathy. [1]
Typically facet joint arthritis is diagnosed with specialized physical examination by specialist physicians such as facet loading (also called Kemps test). However, this test has poor sensitivity (50-70%) [5] and specificity (67.3%) [6] for lumbar facet pain. Often providers perform diagnostic injections to determine if the facet joint is the ...
Waddell, et al. (1980) described five categories of signs: Tenderness tests: superficial and diffuse tenderness and/or nonanatomic tenderness; Simulation tests: these are based on movements which produce pain, without actually causing that movement, such as axial loading and pain on simulated rotation
The American Spinal Injury Association (ASIA), formed in 1973, [2] publishes the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI), [3] which is a neurological exam widely used to document sensory and motor impairments following spinal cord injury (SCI). [4] The ASIA assessment is the gold standard for ...
Reflexes usually are mediated at the level of the spinal cord through reflex arcs. In humans, mono-, oligo-, and poly-synaptic reflex arcs, propriospinal interneuron systems, and internuncial gray matter neurons collectively participate continuously to produce spinal cord reflex that activates muscle.
