Myotomes / Dermatomes / Tendon Reflexs Flashcards
What are myotomes used for in assessment?
Assess motor function of a nn root.
Used to determine mm strength and possible nn issues.

What is the procedure of Testing Myotomes?
You need to use Isometric mm resistance for myotomes
What is Dermatomes Testing used for?
Assesses the sensory portion of a specific nn root.
What is the procedure of testing Dermatome?
When assessing dermatomes you would use a Sharp object and or a Dull or soft object.
What do you expect to see when assessing dermatome?
Results are typically comparative between both sides of a client’s body.
What are the Grades for mm strength testing?
Grades 0-5
What is a Grade 0 mm strength?
No contractile activity can be felt in the gravity eliminated position.
What is a Grade 1 mm strength?
Client’s tendons / mms can be palpated, while client is performing the action, gravity eliminated.
What is a Grade 3 mm strength?
Client can tolerate no resistance but can perform the movement through full ROM.
What is a Grade 4 mm strength?
Client can hold position against gravity with moderate to strong procedure.
What is a Grade 5 mm strength?
Client can hold the possession against gravity and max resistance through full ROM.
