ONE REASON WHY WE USE SUPERFICIAL HEAT?
Heat superficial joints with relatively little soft tissue such as the hand, fingers, patella tendon, etc.
Decrease pain
Promote hyperemia to muscles
Promote relaxation
Increase flexibility of superficial tissues before stretching or exercise
ONE REASON WHY WE USE CRYOTHERAPY?
Cold is typically the thermal agent of choice in the management of acute injuries
vasoconstriction reduces bleeding in the area
It decreases metabolic rate
It decreases pain
It may decrease acute spasm
ONE REASON WHY WE USE ELECTRICAL AGENTS?
Pain relief:
Gate control theory
Endogenous opiate release (endorphins, dynorphins, enkephalins)
Counter-irritant (counter-sensation) theory
Placebo
Reduction of muscle spasm
Muscle re-education
Muscle strengthening
Reduce edema
Reduce muscle guarding
HOW MANY LAYERS ARE NEEDED FOR A CERVICAL HEAT PACK?
4-5
COLD PACK
ICE MASSAGE
WHAT DOES TENS STAND FOR?
Transcutaneous Electrical Nerve Stimulation
HOW MANY LAYERS ARE NEEDED FOR A LUMBAR HEAT PACK?
7-8
WHAT TEMPERATURE DO WE KEEP THE COLD PACKS AT?
Packs maintained typically 0-32°F
WHAT DOES NMES STAND FOR?
NEUROMUSCULAR ELECTICAL STIMULATION
HOW MANY LAYERS ARE NEEDED FOR A THORACIC HEAT PACK?
5-6
HOW MANY TOWEL LAYERS ARE NEEDED FOR COLD PACKS?
1
Clinic pre-set: 200 µsec, 120 pps, Continuous
ONE CONTRAINDICATION OR PRECUATION FOR THERMOTHERAPY MODALIITES?
Peripheral vascular disease
Decreased or absent sensation
Patient who is unable to give feedback (i.e. child, cognitive impairment, etc.)
Malignancies (i.e. areas of known cancer)
Over pregnant uterus
Extreme obesity
Bleeding disorders, e.g., hemophilia
Over acute inflammation
Over areas of active infection
Over metal (staples, etc.)
ONE CONTRAINDICATION OR PRECUATION FOR CRYOTHERAPY MODALIITES?
Ask the patient if they have ever had any unusual response to cold such as a rash or severe pain.
Cold Hypersensitivity Responses
Cold urticaria - secondary to release of histamine from mast cell degranulation resulting in edema of dermis and subcutaneous tissues
Smooth, slightly elevated patches, red or pale
Vasospastic disorders
Raynaud’s disease - a vasoconstriction of the distal extremities, upon exposure to cold. Most prevalent in the hand.
Livedo reticularis - cyanotic mottling of the skin in a typical fishnet pattern
Acrocyanosis - characterized by a persistent diffuse cyanosis of fingers, hands, toes, and feet.
Nerve repairs
Complex Regional Pain Syndrome (CRPS)
Decreased sensation
Peripheral vascular disease
Hypertension (systemic application of cold may increase BP)
Risk of peripheral nerve injury (e.g., peroneal, median) with prolonged exposure and/or compression
ONE CONTRAINDICATION OR PRECUATION FOR ELETRICAL MODALIITES?
High intensity about the heart
Over the carotid sinus
In areas of neoplasm or infection may irritate the tissue
In individuals who cannot give clear feedback
About the trunk of pregnant women
In areas of thrombophlebitis (may have DVT’s)
Patients with pacemakers or other implanted electrodes as it may interfere with their signal
Over areas of excess adipose tissue (may not get to muscle and/or levels of stimulation needed may cause ANS response)
In close proximity to diathermy as they may interfere with each other
Caution must be used when treatment is applied in patients with decreased sensation
Where active motion is contraindicated (tendon repair, fracture)
Seizure disorders (transcerebral)
Over open wounds (unless treating the wound)
