16
Q

advantage IFC

A

Stimulates tissues deeper than TENS
Larger treatment area than with TENS
Possibly more comfortable than TENS

17
Q

how does the premodulated is create in IFC

A

Locate the center of pain and create an “X” around the center with the four pads

18
Q

IFC disadvantage

A

Eliminates pain, not treating the cause
May mask more serious problems
Few if any portable units

19
Q

what can be treat with IFC

A

acute pain, chronic pain, muscle spasm, nerve block, bone healing, edema control

20
Q

electrode placement IFC

A

A: crisscross painful area, dermatome of involve tissue
C: crisscross painful area, dermatome of involve tissue
MP: crisscross local trigger point
NB: over local peripheral nerve, innervating the painful area
BH: crisscross fracture
E: crisscross swelling

21
Q

output intensity IFC

A

A: pleasant tingling without contraction
