Sprains and Strains -Butcher

Question 1

Biomechanical Model of Ligament/tendon Injury says:

Answer 1

Acute injury occurs when a ligament or tendon is subjected to tensile stress (load) that exceeds it’s tensile strength.

Overuse injury occurs when ligament or tendon is subjected to repetitive tensile stress at a frequency, duration, and intensity that exceed its capacity for recovery or repair.

Question 2

What factors can keep you from finding the endpoint in a ligament you are examining?

Answer 2

Muscle tone
Muscle guarding
Joint effusion
Soft tissue swelling
Mechanical block
Ligamentous endpoint

Question 3

Initial sprain/strain treatment?

Answer 3

P	Protection
R	active Rest
I	intermittent Ice
C	Compression
E	Elevation
M	anti-inflammatory Medication
M	anti-inflammatory Modalities

Question 4

3 degrees of sprains?

Answer 4

Grade 1: Micro-tears (stretch)

Grade 2: Macrotears (partial tear)

Grade 3: Complete disruption

Question 5

What is functional instability?

Answer 5

Described as “giving out”

Unable to perform things like: jumping, pivoting, decelerating quickly

Question 6

What is active rest?

Answer 6

Getting joint moving as soon as possible with precautions:

Activity is performed in a biomechanically normal position
Protected from abnormal motion
No pain with activity
No pain or swelling after activity
