Physical Medicine Part 4 Flashcards
What are the indications for use of Diathermy?
Chronic inflammation (bursitis, tendinitis, inactive IBD), bronchitis, pneumonia, pleurisy, chronic cystitis, chronic prostatitis, chronic sinusitis, muscle guarding, spasm, hypertonicity, adhesions, tenosynovitis, intercostal neuralgia, chronic strain/sprain, contusion
What is a contraindication for use of Diathermy?
Long term use or overuse, areas of low vascularity, hypothermasthenia, hemorrhage, menstruation, phlebitis, anticoagulant therapy, over growing bones, gonads, the brain, heart, or gravid uterus, regional metal implant, metal in the field, metal IUD, hearing aids, pacemaker, TB, CA, acute inflammation
What is the mechanism of Diathermy?
Non-ionizing electromagnetic field (22.17 MHz radio waves) radiates out as far as 20’ causing movement of ions inside cells, creating friction and heat that penetrates deeply (>4-8cm) into highly vascular tissues. Vasodilation, hyperemia, and muscle relaxation occur, enhances phagocytosis and waste removal.
What is the proper application of Diathermy?
Position pt on non-metal table, cables not touching pt. Don’t let cables touch pt. Space plates evenly near pt. Towels applied btwn plates and skin. Increase power until needle peaks in tx range (not max power). Pt should feel warm (NOT hot). Duration 5-10min (acute) or 10-15min (chronic)
What is the indication for Therapeutic Ultrasound?
Chronic inflammation, muscle guarding, adhesions, wound healing, joint contracture, sprains, scarring, fascitis, trigger points, bone spurs, plantar warts, edema
What are the contraindications for Therapeutic Ultrasound?
Acute INFXN, pacemaker (tx over thorax), over cancerous lesion, epiphyseal plates (in children), over fx including recently healed, arterial insufficiency, hemorrhage, over eyes, gravid uterus, cervical ganglia or carotid sinus, bony prominences, metallic implants, thrombophlebitis
What is the mechanism for Therapeutic Ultrasound?
Sound waves cause micromassage effects at tissue boundaries. May separate fibrotic tissues. Heating effect penetrates deeply (>5cm) and most prominent at tissue boundaries (none in adipose). Limited use in pain control. U/S conducts poorly through air (must use coupler)
What is the proper application of Therapeutic Ultrasound?
Apply coupling medium. Set timer and intensity (1-2 watts/cm2) and begin tx (lasts 5-10min). Apply transceiver directly to skin and move it slowly, constantly over area, maintain contact. For use of water as coupling medium (for irregular surfaces), there is no need to apply the sound head to the skin directly (keep transceiver moving).
What is the indication for Phonophoresis?
Inflammation in subQ tissues (using anti-inflam substances including 10% hydrocortisone or flavonoids)
What is the contraindication for Phonophoresis?
Acute INFXN, pacemaker (tx over thorax), over cancerous lesion, epiphyseal plates (in children), over fx including recently healed, arterial insufficiency, hemorrhage, over eyes, gravid uterus, cervical ganglia or carotid sinus, bony prominences, metallic implants, thrombophlebitis. Also, allergy to ion to be utilized.
What is the mechanism for Phonophoresis?
Whole medicinal molecules are driven into skin and deeper muscle and nerve by means of U/S. Polarity of substance is irrelevant as it is driven in by mechanical force of the sound, not electrochemical repulsion (as in iontophoresis).
What is the proper application of Phonophoresis?
Apply coupling medium. Set timer and intensity (1-2 watts/cm2) and begin tx (lasts 5-10min). Apply transceiver directly to skin and move it slowly, constantly over area, maintain contact. For use of water as coupling medium (for irregular surfaces), there is no need to apply the sound head to the skin directly (keep transceiver moving).
Mix therapeutic substance into coupling medium (use only substances that mix appropriately; DO NOT use whipped products as the extra air content will decrease sound transmission).
What is the indication for High Voltage Galvanism?
Pain relief (neuritis/neuralgia, radiculitis, sciatica, strain/sprain), trigger points (neg galv), acute pain (+galv, 70-150 bps); chronic pain (+galv 0-15 bps), chronic muscle spasm or weakness (70-110 bps), edema (<10bps), wound healing
What are the contraindications for High Voltage Galvanism?
Through eyes, brain, heart, gravid uterus, CA, INFXN, hemorrhage, pacemaker, acute muscle spasms
What is the mechanism for High Voltage Galvanism?
Depth of penetration depends on peak current (ave 1-1.5mA, up to 2500 mA), tissue conductivity (muscle/nerve/skin >adipose >bone) and nerve selectivity. Penetration >low volt galv. Reduces pain and muscle spasm, tonifies and “re-educates” injured muscles, dec. edema. Polarity of active pad minor issue (+ pole analgesic, vasoconstriction, antimicrobial; neg pole for trigger points, vasodilation, softens adhesions, exercises muscles)
What is the proper application for High Voltage Galvanism?
Wash skin. Power off. Apply large indifferent pad to thigh or low back (whichever is furtherest from active pads). Apply active pads (2 to 4, >1” apart). Slowly increase power (1-2 mA/inch2 active pad) to point of uncomfortable sensation. Gauge intensity based on desired effect. 20-30min duration (1-5min for small pain points; 45 min for chronic pain/edema).
What is the indication for Low Voltage Galvanism?
Denervated muscles, restricted joint motion, passive exercise (low freq), arthritis, neuralgia, myalgia, sprains, strains, acute pain (+galv), chronic pain (neg galv), decubitus ulcers, to perform iontophoresis, adhesions (neg galv), entropion and ectropion (+galv), excessive scarring (neg galv)
What are contraindications for Low Voltage Galvanism?
Hypoesthesia, near gravid uterus, transcerebral, transcoronar, mets CA, pacemaker, metallic implants, metal in field, and for the love of everything holy, DO NOT suddenly break the circuit
What is the mechanism of Low Voltage Galvanism?
Acid-based reactions under the active pad contribute to benefit but can cause burns. Slightly warms tissues. Effects depend on polarity of active pad (+ pole hardens scars, downarrow nerve irritability, vasoconstricts, dec. bleeding, contracts tissue, analgesic, antimicrobial; neg pole softens scars, increases nerve irritability, vasodilator, hyperemic, increases bleeding, relaxes tissue, hypersensitizing (low intensity)
What is the proper application of Low Voltage Galvanism?
- Secure pads soaked in saline to skin
- Inactive pad on thigh or low back (4x >area than active pad)
- Slowly increase power (max dose 1-2mA/sq inch active pad or pt sensation) Do not exceed during therapy (skin and nerves adapt). 10-20min duration.
- Slowly dec. power near end.
- To stimulate denervated muscle use 0.5-40 Hz freq and turn power up in short pulse mode (turn power off as soon as muscle contraction occurs to avoid burns
