PULSED ELECTROMAGNETIC THERAPY
Cellular mechanism
Upregulates the bodies natural healing process - only works on damaged tissue
Movement of electrons and ions through the cell membranes
This triggers a release of intracellular calcium ions = leads to increased binding of Ca2+ to calmodulin = activates myosin light chain kinase enzyme.
This binding produces NO. NO causes upregulation of anti-inflammatory responses, increases blood flow and increase growth factor production
Growth factors trigger pathways which reduce inflammation and support neovascularisation, tissue regeneration + remodelling
Generation of a low-level electromagnetic field that optimises the bodies ability to repair and re-establish the normal cellular voltage
MLCK can trigger cell spreading, migration and cytokinesis, neurite outgrowth and platelet morphogenesis
Pain relief
Electromagnetic field disrupts the brains ability to transmit pain by decreasing the nerve cell potential from -70 to -90mv
This means cell voltage is too low when the pain signal is detected, for the synapse to trigger release of the chemical transmitters = this then blocks the pain signal
PEMF can induce endogenous opioids
Vasodilation
After 72 hours
NO causes dilation of the capillary sphincter = vasodilation
Increase in blood flow = increase nutrients and removal of toxins
Bone healing
Electromagnetic field and movement of ions increases expression of osteoblasts which induces osteogensis and promotes differentiation of osteoblast cells = bone repair
Blood flow will help with bone healing
electromagnetic waves mimics cyclical loading which also stimulates bone healing
Global effects
Pain relief
Upregulates healing of damaged cells
Vasodilation
Vasoconstriction (first 72 hours)
Bone healing
Increase in growth of neurons
Relaxation
Settings:
Pain: 200Hz, 10-15 minutes/ 4 hours
Acute: PPS = constant
Chronic: PPS = 5
Circulation: 50Hz, 10-15 minutes / 4 hours
Vasoconstriction: PPS = 5
Vasodilation: PPS = 17.5
Neurological: 200Hz, PPS = constant. 10-15 minutes / 4 hours
Fracture: 50Hz, PPS = constant, 20 minutes TID until callus established then BID until mobilised then SID
Vasoconstriction (1st 72 hours)
Electromagnetic waves causes capillary sphincter to contact = reduces swelling, pain
Neurological
In nerves, schwann cells repair when damaged, PEMF optimises healing in these cells. PEMF can increase growth of nerves and re-establish cellullar currents
