Phys med Q&A

Questions:

1)  For pain control with edema, which is most appropriate: MENS, TENS or Interferential Current (IFC)?

2)  Which form of physical medicine involves an electrode which repels ions with 'like' charges and helos these ions penetrate the subcutaneous tissues?

3)  Which of the following concentrates in bone/periosteum: diathermy or ultrasound?

4)  Transcutneous Electrical Neuromuscular Stimulation (TENS) is indicated for?

5) Which form of electromagnetic radiation is indicated for pain and fracture healing?

6)  Name two indications for MENS.

7)  What are the advantages of diathermy over ultrasound?

8)  What is diathermy? Name 7 contraindications to diathermy use.

9)  The gate-control theory was the rationale behind the development of which pain controlling machine?

10) Why is ultrasound contraindicated in cases with blood stasis?

YOU ARE AWESOME!!

Answers:

1) IFC

2) Iontophoresis

3) Ultrasound

4) Pain relief and reduce muscle spasms (Pain is the primary use, not to improve healing)

5) Laser

6) Analgsia and stimulation of the healing process (Microcurrent Electrical Neuromuscular Stimulator)

7) Can heat deeper tissues and can heat larger areas than US.

8)  Shortwave electromagnetic energy that produces heat within tissues. Contraindications:

1) Acute injury or inflammation, 2) Metal implants or pacemakers (can become hot and or interfere directly with actions), 3) Malignancy (may promote growth), 4) Pregnancy (concerned with deep heat and EM field for fetus), 5) Eyes (heat may damage internal structures), 6) Testes (heat may effect fertility), 7) Growing epiphyses (effects unknown)

9)  TENS

10) The standing waves can damage the endothelial lining and lead to further blood stasis.
