Let's make a deal (with physiotherapists): Easter Edition (CH15) Flashcards
What does ESTHR stand for?
Electrical stimulation for tissue healing and repair
What three types of current are used for ESTHR?
Microcurrent, low intensity direct current, and HVPC or high-voltage pulsed current
What is the rationale for ESTHR intervention?
Accelerating the healing phase of slow to heal, chronic, cutaneous wounds
Describe a microcurrent wave:
Continuous or pulse modulated and monophasic that does not exceed 1 mA
Describe an HVPC wave:
Twin-peak, monophasic, peak voltage of 500 V, with a duration of 10-100 microseconds
What is the “current of injury”?
The shift in the body’s electrical system that recruits the appropriate cells/substances for healing
How does ESTHR act on the current of injury?
It enhances/increases it
The attraction of cells to a certain charge is called what?
Galvanotaxis
What types of cells are recruited with anodal therapy?
Neutrophils and macrophages
What stage of healing would anodal therapy be used for?
Inflammatory phase
What types of cells are recruited with cathodal therapy?
Fibroblasts, Epidermal cells, and Keratinocytes
What stage of healing would cathodal therapy be used for?
Proliferative and Remodeling phases
HVPC is also said to have what effect with regards to microorganisms
Germicidal
Which statements about HVPC are supported/conflicting or not-supported by literature:
1) Retard posttraumatic edema
2) Increase muscle strength and blood flow
3) Decrease pelvic floor spasms
4) Decrease delayed onset muscle soreness
5) Decrease pain
1 - conflicting
2,4 - not supported
3,5 - supported
Both microcurrent and HVPC should be set to patient ______.
Comfort
