Mid-Term Flashcards
When does a soft callus usually form after an injury to a bone?
1-6 weeks
When does a hard callus of a bone usually formation following injury?
4-6 weeks
What stage of injury is controlled motion phase
Sub acute stage - proliferation
What is the protective phase of injury
Acute stage - inflammation
In what joint position is the intracapsular volume capacity the greatest?
Open-packed position
Flexion, extension, abduction, and adduction are all what kind of motions
Osteokinematic
Roll, glide,spine, compression and distraction are all what kind of motions

Describe the convex-concave rule
When convex moves on concave the joint glide direction is OPPOSITE to direction of physiological movement
When concave moves on convex the joint glide direction is the SAME as the physiological movement

Pain that occurs with resistence, accompanied by pain at the opposite end of passive range, indicated what?
Muscle impairment
Pain that does not occur during the test but occurs after the release of contraction is thought to be sourced where .
