Soft Tissue Injury and Microtrauma

Question 1

What are the grading levels of injuries?

Answer 1

Grade 1-3

Question 2

What is a Grade 1 Ligament Sprain?

Answer 2

Some stretching or perhaps tearing of the ligamentous fibers, with little or not joint instability. Mild pain, little swelling and joint stiffness.

Question 3

What is a Grade 2 Ligament Sprain?

Answer 3

There is some tearing and separation of the ligamentous fibers and moderate instability of the joint. Moderate-to-severe pain, swelling and joint stiffness expected

Question 4

What is mechanical energy

Answer 4

The energy of position or deformation

Question 5

What are the two primary forms of mechanical energy

Answer 5

Gravitational Potential Energy (Ep=mgh) and Deformation/strain energy (stored in the body): Es=1/2kΔ x 2

Question 6

How does mechanical energy relate to exercise?

Answer 6

Because if the DEFORMATION of the various tissues associated with a movement EXCEEDS the material limits, it can cause injury.
