Chapter 4 Arthrokinematics Flashcards
Osteokinematic Motion
Bone moving on another = angular motion
(AROM) or (PROM)
- Can be measured
End Feel
Nature of resistance at end range for AROM or PROM
Bony end feel (normal)
Hard and abrupt limit to joint motion
Occurs When bone contacts bone
Example: elbow extension
Capsular end feel (normal)
Firm, leatherlike limitation of motion that has a slight give
Example: all normal joint motion of the shoulder
Soft tissue approximation (normal)
Soft end feel which has much more give to it. Muscle or adipose tissue preventing further motion
Example: forearm pressing on biceps with elbow flexion
Bony end feel (abnormal)
Hard block where not expected
Example: hard end feel at end range knee flexion
Boggy end feel (abnormal)
Has a soft, “wet sponge” feel to it
Usually present in areas of acute edema due to trauma
Muscle spasm (abnormal)
Reflexive muscle guarding during range of motion. Verified with palpation
Usually seen as a protective response during the acute phase of injury
Empty end feel (abnormal)
Lack of mechanical limitation to joint range of motion
Occurs when motion is limited by pain or patient unease or there is disruption of soft-tissue constraints
Springy block
Rebound movement felt at end range
Occurs with internal derangement of a joint…e.g. Torn cartilage
Arthrokinematic motion
Joint surface motion during osteokinematic motion. Joint Play Joint Mobilization Joint Manipulation Roll, Glide, Spin
Component movement
motions that accompany active motion but are not under voluntary control
Joint play
Movements between joint surfaces done by applying external force.
Joint mobilization
Passive oscillatory motion or sustained stretch that is applied at a slow enough speed by an external force that the individual can stop the motion
Joint manipulation
Passive movement applied with a very forceful thrust within a short range that cannot be stopped. Often times performed under anesthesia.
