|
active insufficiency |
point muscle can not contract further due to tension within the muscle is insufficient at both extremes (agonist) usually bi-articulate muscle |
|
|
passive insufficiency |
point muscle can not stretch further due to stretch-ability within the muscle is insufficient at joints (antagonist) usually bi-articulate muscle |
|
|
tenodesis |
with elbow on table, flexing the wrist has a tendency to extend fingers
opposite movement flexes fingers |
|
|
long axis of a muscle |
longest measurement of a muscle length of a muscle |
|
|
speed |
force of muscle decreases as speed of contraction increases |
|
|
close chain movement |
distal segment fixed or closed proximal moves through space
|
|
|
open chain movement |
proximal segment remains fixed (stationary) distal moves through space |
|
|
muscle tightness |
immobility can lead to muscle tightness and loss of motion-if severe can lead to joint contracture |
|
|
joint contracture |
joint incapable of full motion |
|
|
muscle guarding |
muscle tightens to help protect the body from further injury |
