Modalities

QuestionAnswer
What would you increase to achieve Sensory TENS instead of Motor TENS Frequency
Physiological effect of general heat application Inc: CO, metabolic rate, pulse, RR, vasodilation Dec: BP, blood to internal organs, SV
Contraindications to superficial thermotherapy Dec circulation, malignant tumors
Indications for Whirlpool or Hubbard tank decubitus ulcers, open burns and wounds, postsurgical conditions of the hip, subacute and chronic MSK conditions, RA.
Contraindications for Whirlpool bleeding, cardiac instability, bowel incontinence
Precaution/Contraindication to Aquatic Therapy Unprotected (uncovered) open wounds, unstable BP
Physiological effects of general cold application Dec: metabolic rate, pulse, RR, venous blood pressure Inc: blood flow to internal organs, CO, SV, arterial blood pressure
Contraindications to Cryotherapy Cryoglobulinemia, paroxysmal cold hemoglobinuria, over regenerating peripheral nerves
Contraindications to Contrast Baths Advanced arteriosclerosis, arterial insufficiency
When is continuous US used? chronic conditions, has thermal effects
When is pulsed US used? acute soft tissue injuries. Has non-thermal effects. Low intensity, pulsed US for wound care.
What mode for phonophoresis? Pulsed: 20%
Weight (CS) and %BW (LS) required for soft tissue using traction CS: 12-15lbs, LS: 25% BW
What type of current is used during iotophoresis? continuous direct current
Salicylate pain relief (-)
lithium gout (+)
lidocaine pain relief (+)
acetate calcium deposits (-)
copper fungal infections (+)
magnesium or calcium muscle spasm (+)
hydrocortisone anti-inflammation (+)
iodine soften scars (-)
dexamethasone anti-inflammation (-)
zinc dermal ulcers (+)
Settings, uses for Conventional TENS (high rate) high frequency (75-120 pps), short pulse width (50-100 microseconds), low intensity. Temporary relief of acute or chronic pain.
Acupuncture-like TENS (strong, low rate). Low frequency, wide pulse width, higher intensities than conventional TENS. Chronic conditions.
Brief Intense TENS high pulse rate, long pulse width. Short term pain relief for painful procedures (i.e. wound debridement)
Burst mode TENS combines characteristics of both high and low rate TENS. Used if patient can't tolerate Low rate TENS.
High-voltage pulsed monophasic stimulation indication: denervated muscles, dec pain, dec edema, wound healing
Use of FES w/ innervated muscle Alternating Current
Use of FES w/ denervated muscle Direct current that is interrupted w/ a long pulse width
What is duty cycle. How does it change w/ muscle atrophy? current "on" time vs. "off" time. Ratio should increase as muscle atrophy increases to prevent fatigue. Min atrophy= 1:1, Severe atrophy 1:5
Chronaximetry the minimal amount of time that a current must be on in order to produce a minimal muscle contraction. The lower the # of milliseconds the greater the nerve's excitability.
Indication of denervation on Strength-duration curve a steep, continuous curve displaced to the R
