Short wave diathermy contraindications (penetrates 5 cm)
Shortwave diathermy produces deep heating by the conversion of radio wave electromagnetic energy into thermal energy. Contraindications for shortwave diathermy include metal (pacemakers, intrauterine devices, and implants), contact lenses, pregnancy, menstruating uterus, and skeletal immaturity.
components of an exercise prescription (5)
mode, intensity, duration, frequency, and progression.
Type II muscle fibers
Type 2 muscle fibers are large muscle fibers, with peak tension and relaxation achieved rapidly. They are primarily used for high-intensity, short-duration activities.
What creates more shear stress open or closed kinetic chain exercises?
Open kinetic chain exercises have a distal end (usually the foot) that is not fixed, and create more shear stress than closed kinetic chain exercises.
Temp for hot pack
Hot packs are typically maintained in water baths at 70°C to 80°C. Hot packs should never be applied directly to the skin. There should be towels between the patient and the hot pack to avoid burning the patient’s skin.
ice for 20-30 mins
An appropriate frequency for a therapeutic ultrasound prescription would be
0.8 to 1.1 MHz.
Hydrotherapy mechanism of energy/heat transfer
The main mechanism of heat transfer from hydrotherapy is convection, and it is considered superficial heating.
If no eyewear during microwave diathermy what can occur
Cataract formation
