Question 5

What type of current goes deeper into the body and has less skin irritation?

Answer 5

Alternating current

Question 6

Which goes deeper into the body, higher or lower frequency?

Answer 6

Higher frequency (IFC)

Lower frequency (TENS) - more benefit to tissues

Question 7

What is amplitude?

Answer 7

The intensity of the charge being conducted

Question 8

What machines are for pain relief and which are for muscle strengthening?

Answer 8

Pain relief - TENS, IFC

Muscle strengthening - EMS

Question 9

How does the TENS machine work?

Answer 9

1) Pathways
Brain doesn’t sense the pain when using but this is…
SHORT ACTING

2) Stimulates body to release opioids
–> “endogenous opioid stimulation and release” and this is…
LONG ACTING

Question 10

What is lower frequency better for? What is higher frequency better for?

Answer 10

Lower frequency - therapy/tissues

Higher frequency - goes into body easier

Question 11

Why would you use ICF instead of TENS?

Answer 11

1) Goes deeper into the body
2) Use it for swelling

Question 12
