Answer 1

0: Zero. No palpable muscle contraction
1: Trace. Muscle contraction palpable, but no movement
2-: Poor Minus: partial ROM in a gravity-eliminated position
2: Poor. complete ROM in gravity-eliminated position
2+: Poor Plus. partial ROM against gravity
3-: Fair Minus. more than half ROM against gravity but not full

Question 2

What are the names and MMT from 3 to 5 and what do they mean?

Answer 2

3: Fair. Complete range of motion against gravity without resistance
3+: Fair Plus. Complete ROM with minimal resistance
4-: Good Minus. Complete ROM against gravity with min-mod resistance
4: Good. Complete ROM against gravity with mod resistance.
4+: Good plus. complete ROM against gravity with mod-max resistance
5: Normal. Complete ROM against gravity with max resistance.

Answer 14

5-10 pounds

Question 15

What position would you test TFL in?

Answer 15

supine

Question 16

What position would you test bracioradialis?

Answer 16

supine

Question 17

What position would you test quadratus lumborum?

Answer 17

prone

Question 18

What position would you test coracobrachialis?

Answer 18

Sitting

Question 19

How is pec minor tested?

Answer 19

The pectoralis minor muscle originates on ribs three to five and inserts on the coracoid process of the scapula. The muscle is tested by positioning the patient in supine. Pressure is applied against the anterior aspect of the shoulder, downward toward the table.
