TENS & IFC Flashcards
TENS and ICF
What might be a reason IFC (quadripolar) might be used over TENS?
larger surface areas
TENS and ICF
TENS Patients with rate responsive pacemakers or ICDs
no, contrainidicated
TENS and ICF
TENS Over metal implants?
no, contrainidicated, causes unnecessary pain due to electrical current-induced overheating of implants
TENS and ICF
What are the stimulation levels of TENS?
- Sensory: large A-beta fibers. Gate system
- Motor: Large Diameter afferents (A-beta) & efferent motor (alpha)
- Noxius: Large Diameter afferents (A-beta) & efferent motor (alpha) & nociceptive (A- delta and C fibers)
TENS and ICF
Should you see muscle contractions when applying TENS on the burst mode?
yes, sensory and motor estimulation. A-delta, C and Alpha fibers
TENS and ICF
Can a pt use NMES or TENS if muscle contractions are contrainidicated?
- No NMES
- TENS only on the sensory threshold
TENS and ICF
TENS Over or around the lumbar, abdominal area and hips of pregnant women?
no, contraindicated, induces labor
TENS and ICF
Low frequency, amplitude modulated electrical current that interference between 2 (or 3) currents consisting of differing medium carrier frequencies (usually 3000-5000MHz).
ICF, interferencial current
TENS and ICF
Where does the interference of current occurs with a
quadripolar set up?
Where does the interference occurs with a
bipolar set up?
- quadripolar set up: in the tissues
- bipolar set up: in the machine
TENS and ICF
TENS over the anterior cervical area?
no, contrainidicated
TENS and ICF
TENS over cranial area?
no, contrainidicated
TENS and ICF
TENS over damaged skin?
no, contrainidicated
TENS and ICF
TENS stimulates what type of nerve fiber?
- Sensory: Large A-Beta
- Motor: A alpha
- Nociceptive: Small A-delta & C fibers
TENS and ICF
TENS decreases pain via…
peripheral nerve depolarization.
TENS and ICF
Should you see muscle contractions when applying TENS on the brief intense mode? Why?
Yes, depolarization of all nerve fibers
