SM Mechanisms of Injury

MOI is

• How the body responds to injury

• The general idea of what the injury is

• How the injury occurred

• Why an Injury happens

Stress/Strain Curve attempts to

• Describe the mechanics of injury

• Define the ability for tissue to return to normal function

• Identify the failure point of tissues by the increase of strain

• Show how stress and strain initiate force upon a tissue

• Is the torque needed to cause a tissue to fail

Which is not a tissue property?

• Load

• Deformation

• Plastic

• Creep

• Structural Failure

Identify the types of tissue loading

• Compression

• Shear

• Bending

• Distraction

Physical injury or wound that is produced by an external force is

• Trauma

• Overuse

• Acute

• Chronic

When an injury does not resolve or respond to treatment for an extended duration of time is

• Trauma

• Overuse

• Acute

• Chronic

Identify the type of strain: Palpation can reveal holes or divots in the muscle belly

• Grade 1

• Grade 2

• Grade 3

• Not a strain, but a sprain

Identify the type of strain: Extremely painful and loss of movement in that muscle

• Grade 1

• Grade 2

• Grade 3

• Not a strain, but a tear

Chronic or overuse injury to the tendon resulting in pain and decreased function is

• Tendonopathy

• Tenosynovitis

• Tendinous Spasm

• Guarding

What is not a structure of a synovial joint?

• Bones

• Ligaments

• Tendons

• Bursa

• Fibroelastic cartilage
