What is one contraindication for using heat?
Injuries within 48 hours. If there is active swelling you shouldn't use heat.
WHat are 3 indications for use of ultrasound for injuries?
- 1. Edema
- 2. Pain
- 3. Adhesions/scar tissue.
What are the contraindications to TENS unit?
Contraindications: Pacemakers and Pregnancy
- Stands for:
- Transcutaneous electrical nerve stimulation
- -A pocket size, battery-operated device that provides mild, continuous electrical current through the skin by using 2 to 4 electrodes
-High TENS (100-500Hz) relieves pain by blocking pain fibers and is used up to 24 hrs/day because when the unit is turned off the pain cycle often returns.
-Low TENS (1-50Hz) relieves pain by endorphin release, and due to the 4 hour 1/2 life of endorphins need only be used 15-30 min at a time.
When can you use iontophoresis
Usually used for such things as topical anesthetics, antiinflammatories and muscle relaxants
Compare Isometric to Isotonic to Isokinetic contraction.
- Isometric contraction:
- Static contraction- muscle contraction that is not associated with joint motion or change in muscle length. Can be performed in a cast.
- Isotonic contraction:
- Dynamic contraction - muscle contraction with associated joint motion and change in muscle length, either eccentric or concentric.
- Eccentric contraction: muscle contraction in which the muscle lengthens while contracting. Contraction force of muscle is against an overpowering weight resistance
- Concentric contraction: Where a weight is lifted with the force of muscle contraction
Isokinetic contraction: contraction at a constant velocity at all ranges of motion by using a machine with an accommodating resistance.
