The Thyroflex tests the reflex of the Brachioradialis muscle (which sits directly
under the Extensor Digitorium muscle); therefore, consistency and accuracy of
the test is dependent on finding and hitting this correct muscle.
Dorsiflex Hand
Locate muscle 2-3 fingers from elbow crease.
(2 for large hands, or 3 for petite hands)
5.
This is the most critical part of the test.
To locate this muscle and mark
it for ease of testing, have patient dorsiflex their hand, straighten all fingers out,
hold, and have the patient wiggle the middle finger only. Locate the muscle group
that is moving (distal to the elbow crease on the forearm and approximately two
to three fingers down) and mark the muscle with an “
X
.”
6.
Always utilize the blue reflex hammer provided to strike and to test the muscle
reflex. If the correct muscle has been marked, the patient will have a strong
middle finger reflex. If patient wrist reflex sideways, use the blue reflex hammer
to hit a little bit over to the right or left of the mark on the forearm until patient
display a strong middle finger reflex. Remark that spot. If you get the middle
finger to fire, you are ready to proceed with the test. Do not test unless the middle
finger fires.
Test correct muscle Look for a strong middle finger reflex
