test each key sensory area in each derm and then two other sites within the derm
the key sensory area (dermatome only) tests for radiculopathy (compression of nerve at spinal root)
within the dermatome (cutaneous nerve region) tests for peripheral nerve entrapment

dorsal:
medial and lateral plantar nerves (same as plantar)
saphenous (medial foot)
sural (lateral)
deep fibula nerve (in betwwen 1/2 toes)
superficial fibula nerve (dorsum of foot)
48
what is the difference between dermatomes and cutaneous innervation?
dermatome- area of skin supplied by a single pair of spinal nerves (eg L4), a problem here would indicate a problem at the nerve root
cutaneous innervation- areas innervated by specific peripheral nerves (nerves that track off the nerve roots) eg lateral cutaneous femoral nerve, this indicates a problem further down in a specific peripheral nerve
49
how can you test radiculopathy?
straight leg testing, lay them flat and raise a leg to see if any pain is felt in back to suggest nerve root entrapment
normal is greater than 90 degrees, depends on age
the slump test, seated and clasps hands behind back, they slump forward to put their spine in flexion, the client also extends out their knee and flexes their foot. this puts tension on the spinal cord and nerves
