  1. Cryotherapy Contraindications
    • Compromised circulation, peripheral vascular disease
    • Ischemic tissue, infection
    • Cryoglobulinemia
    • Raynaud's phenomenon
    • Cold urticaria
  2. Cold Pack
    • Requires a temperature of 23 degrees F
    • Apply wrapped in moistened towel for 15 minutes
    • Require frequent observation of the skin
  3. Cold Bath
    • Requires a temperature of 55-64 degrees F
    • Immerse body part for 5-15 minutes
  4. Heat Therapy Contraindications
    • Circulatory or sensory impairment
    • Area of malignancy
    • Acute trauma, bleeding, or hemorrhage
    • Thrombophlebitis
    • Arterial disease
  5. Hot Pack
    • Must be stored in hot water between 158-167 degrees F
    • Six to eight layers of towel, 20 minutes
    • Check skin after 5 minutes for redness or signs of a burn
  6. Ultrasound Contraindications
    • Over eyes, heart, testes
    • Over pregnant uterus
    • Cemented prosthetic joint
    • Sensory or circulatory impairment
    • Thrombophlebitis
    • Over epiphyseal areas in children
    • Infection, or malignancy
  7. Duty Cycle
    • The portion of the treatment time that ultrasound is generated during the entire treatment
    • 100% produces thermal effects
    • 20% or pulsed, produces non-thermal effects
  8. Ultrasound Frequency
    • 1 MHz heats tissues up to 5 cm deep
    • 3 MHz penetrates tissues less than 2 cm
  9. Ultrasound Intensity
    • Continuous ultrasound: between .5 to 2 W/cm2
    • Pulsed ultrasound: .5 to .75 W/cm2
  10. Traction Contraindications
    • Joint instability
    • Tumor
    • Pregnancy
    • Osteoporosis
    • Fracture
    • Acute sprain or inflammatory response
  11. Traction Indications
    • Nerve impingement
    • Herniated or protruding disk
    • Joint hypomobility
    • Degenerative joint disease
    • Paraspinal muscle spasm
    • Osteophyte formation
  12. Cervical Traction
    • Position in supine with 25-35 degrees of flexion
    • Start with 10-15 pounds and progress to 7% of the patient's body weight
  13. Lumbar Traction
    • Initial treatment 25-50 lbs is recommended
    • Force of up to 50% of body weight is required to separate the vertabrae
  14. Compression Contraindications
    • Malignancy of treated area
    • Deep vein thrombosis
    • Heart failure, pulmonary edema
    • Infection of treated area
    • Circulatory obstruction
  15. Compression Treatment Parameters
    • 3:1 ratio, on/off time
    • Pressure ranges from 30-80 mm Hg and should not exceed the patient's diastolic BP
  16. Direct Current
    • aka galvanic current
    • A constant flow of electrons with a constant polarity
  17. Alternating Current
    • Polarity continuously changes from pos to neg with the direction of current flow
    • Used in muscle retraining, spasticity, and stimulation of denervated muscle
  18. Inferential Current
    • Attempts to reach deeper tissues using two high frequency alternating waveforms
    • Used in pain management, urinary incontinence, edema management, and migranes
  19. Russian Current
    • Depolarizes both sensory & motor nerve fibers
    • Results in tetanic contractions that are painless and stronger than those made voluntarily
    • Sets of ten contractions, ten seconds long with 50 second break between each set
  20. Cathode
    Negatively charged electrode that attracts positive ions
  21. Anode
    Positively charged electrode that attracts negative ions
  22. Amplitude
    • aka intensity
    • How much
  23. Current
    Describes the flow of electrons from one place to another
  24. Frequency
    Determines the number of pulses delivered through each channel per second
  25. Voltage
    How fast the electricity is moving
