Describe the steps of a dermatome screen
Patient sits with their hands on their lap, palms up, eyes closed, deliberately "swipe"
over an area corresponding to a specific nerve root, compare sides and grade

What is a myotome screen?
Resistive test that corresponds to spinal nerve root innervation AND peripheral nerve!
Tests motor function
If a nerve root is pinched or there is a lesion how is the muscle effected?
The muscle it corresponds to will be weak (the corresponding area on the skin will also
lack sensation)
How would you preform a myotome assessment evaluating C5?
Resisted should abduction/elbow flexion! Both arms in a broken "T"/scarecrow position
and pushing down evenly on both sides OR patient makes a muscle, you pull wrist back
towards you while they try to pull towards them
How would you preform a myotome assessment evaluating C6?
Resisted wrist extension/elbow flexion! Patient makes a fist and tries to resist as you
push down on it towards the ground OR make a muscle, pull wrist back towards you
while they try to pull towards them
How would you preform a myotome assessment evaluating C7?
Resisted elbow extension! Patient makes a muscle, you push their arm towards them
while they try to extend it out towards you
How would you preform a myotome assessment evaluating C8?
Resisted finger flexion/thumb extension! Put 2 fingers out and have patient wrap around
and squeeze OR have them do a thumbs up and resist while you push down on the
thumb
