Phonophoresis/US Flashcards
What are the treatment parameters for phonophoresis
Nonthermal
20% duty cycle
0.5-0.75 W/cm2 intensity
5-10 min
3 MHz
(LIKE A SMALL INFLAMED MUSCLE) !!!
What are indications for US
Heating
Tendinopathies
Pain
Stress fractures
Bone healing
Soft tissue repair
Wound repair
Why would we use the mode continuous
Heat up a tissue to decrease pain
Why would we use the mode pulsed
Used for tissue and bone healing and maybe swelling
Clinical effects of thermal US
Increases soft tissue extensibility
Decrease pain
MAIN CLINICAL EFFECTS (has the same effects as putting heat but more localized and deeper)
Effects of non thermal US
Promote angiogenesis
Increase collagen for tendon healing
Increase protein synthesis
What’s the general rule for duration for US
5-10 min for 2x the size of ERA
What are the clinical applications for thermal US
Prior to stretching and mobilization
Reduction of pain
What are the clinical applications for non thermal US
Altering cell membrane permabaility
Accelerate tissue healing
- dermal ulcers
- surgical skin incisions
- tendon injuries
- bone fractures
Contraindications for US
Pregnancy
Active bone growth
Can are
DVT
Blood conditions
Pacemakers
US precautions
Acute inflammations
Growth plates
Fractures
