Abnormal End-Feels Flashcards
Produced by articular surface rebounding from intra-articular meniscus or disc; if forced further, something will give way
Springy
Rebound sensation as if pushing off from a rubber pad
Springy
Example of normal springy end-feel…
Axial compression of C/s
Knee flexion or extension c displaced meniscus
Springy
Produced by viscous fluid (blood) within joint
Boggy
“Squishy” sensation as joint is moved toward its end range; further forcing feels as if it will burst joint
Boggy
Hemarthrosis @ knee
Boggy
Produced by reflex and reactive muscle contraction in response to irritation of nociceptor, predominantly in articular structures and muscle; further forcing feels as if nothing will give
Spasm
Abrupt and “twangy” end to movement that is unyielding while the structure is being threatened but disappears when threat is removed (kicks back)
Spasm
With joint inflammation, it occurs early in range, especially toward close-packed position, to prevent further stress
Spasm
With irritable joint hypermobility, it occurs @ end of what should be normal range, as it prevents excessive motion from further stimulating the nociceptor
Spasm
Spasm in grade II muscle tears becomes apparent as muscle is passively lengthened and is accompanied by a painful weakness of that muscle
Spasm
Is muscle guarding an end-feel?
No ==> involves co-contraction
Significant traumatic arthritis, recent traumatic hypermobility, and grade II muscle tears
Spasm
Produced solely by pain; frequently caused by serious and severe pathological changes that do not affect joint or muscle and so do not produce spasm; demonstration of this end-feel is, with exception of acute subdeltoid bursitis, de facto evidence of serious pathology; further forcing increases pain to unacceptable levels
