Classification of Therapeutic Modalities

Electromagnetic Includes cryotherapy, thermotherapy, electrical

stimulating currents, diathermy and lasersRely on electromagnetic energy, which travels at the

speed of lightEnergy travels in a straight lineThe energy can be absorbed, refracted, reflected or

transmitted

ThermotherapyPhysiological Effects of Heat

Dependent on type of heat energy applied, intensity of energy, duration of exposure and tissue response

Heat must be absorbed to increase molecular activityDesired effects

Increase collagen extensibility; decreasing joint stiffness; reducing pain; relieving muscle spasm; reduction of edema and swelling; increasing blood flow

Extensibility of collagenPermits increases in extensibility through stretching

Pain reliefActivates gate control mechanism

Muscle spasmIncreased blood flow reduces ischemia

Assistance w/ healing processRaises tissue temperature, increases metabolism resulting in

reduction of oxygen tension, lowering pH, increasing capillary permeability and releasing bradykinins and histamine resulting in vasodilation

Parasympathetic impulses stimulated by heat are also believed to be a reason for vasodilation

Superficial HeatForm of electromagnetic energy (infrared region of

spectrum) Increases subcutaneous temperature, indirectly

spreading to deeper tissueMuscle temperature increases through reflexive effect

of circulation through conductionMoist heat versus dry heat?

Physiological Effects of ColdType of electromagnetic energy (infrared radiation)Relies on conduction -- degree of cooling depends on

the medium, length of exposure and conductivityAt a temperature of 38.3oF, muscle temperature can be

reduced as deep as 4cmTissue w/ a high water content is an excellent

conductorMost common means of cold therapy are ice packs and

ice immersionWet ice is a more effective coolant due to the energy

required to melt ice

Vasoconstriction Reflex action of smooth muscle due to sympathetic

nervous system and adrenal medulla

Hunting responseIntermittent period of vasodilation will occur if cooling

continues for >20 minutes

Blood viscosity will also increase with extended cooling

Decreases extent of hypoxic injury to cellsDecreases cell metabolic rate and the need for oxygen

through circulation, resulting in less tissue damageDecreased metabolic rate and vasoconstriction

decreases swelling associated w/ inflammatory response

© 2011 McGraw-Hill Higher Education. All rights reserved

Page 22: © 2011 McGraw-Hill Higher Education. All rights reserved Chapter 15: Using Therapeutic Modalities.

Decreases muscle spasmMuscle becomes more amenable to stretch as a result of

decreased GTO and muscle spindle activity

Decreases free nerve ending and peripheral nerve excitabilityAnalgesia caused by raising nerve threshold

Cold is more penetrating than heat Ability to decrease muscle fatigue and increase and

maintain muscular contractionAttributed to the decrease of local metabolic rates and

tissue temperature

CryokineticsTechnique that combines cryotherapy with exerciseGoal is to numb region to point of analgesia and work

towards achieving normal ROMEquipment

Treat area with ice pack, massage or immersion

ApplicationWhen analgesia is experienced, exercises should be

performed (window will last 4-5 minutes)As pain returns, process may be repeatedSequence can be repeated 5 timesExercises should be pain freeChanges in intensity should be limited by both healing and

patient’s perception of pain© 2011 McGraw-Hill Higher Education. All rights reserved

Special Considerations for CryotherapyCooling for an hour at 15.8o - 30.2o F produces

redness and edema that lasts for 24 hours post exposure

Immersion at 41oF increases limb fluid volume by 15%

Exposure for 90 minutes at 57.2o - 60.8o F can delay resolution of swelling up to one week

Some individuals are allergic to cold and react w/ hives and joint pain

Icing through a towel or bandage limits the reduction in temperature -- could limit effectiveness of treatment

Ultrasound TherapyModality which stimulates repair of soft tissue and

pain relief

Form of acoustic energy used for deep tissue heatingOperates at inaudible frequencySound scatters and is absorbed as it penetrates tissues

-- losing energy = attenuation Impedance and penetration are determined by

properties of media (densities)

Page 50: © 2011 McGraw-Hill Higher Education. All rights reserved Chapter 15: Using Therapeutic Modalities.

EquipmentHigh frequency generator which provides

electrical current through a coaxial cable to a transducer applicator

Through piezoelectric effect electrical current is transformed into acoustic energy through contraction and expansion of piezoelectric crystals

Frequency ranges between .75 and 3.0 MHz1 MHz ultrasound allows for deeper penetration

while 3 MHz is absorbed more superficially

Page 51: © 2011 McGraw-Hill Higher Education. All rights reserved Chapter 15: Using Therapeutic Modalities.

Area of transducer that produces sound is the effective radiating areaProduces a beam of acoustic

energy - collimated cylindrical beam with non-uniform distribution

Variability in the beam (beam non-uniformity ratio - BNR) =lower BNR = more uniform energy output

Intensity is determined by amount of energy delivered to the sound head (W/cm2)

Can be delivered as either pulsed or continuous ultrasound

IndicationsProduces thermal and non-thermal effects

Generally used for tissue heating (must increase tissue temp between 104o and 113oF

Non-thermal effects include microstreaming and cavitation which impacts tissue permeability and fluid movement - useful with acute injuries For solely non-thermal effects, intensity must remain below .2

W/cm2

Frequency resonance hypothesis relates to alterations in protein signaling frequency which impact permeability, healing and protein production

Acute conditions require more treatments over a shorter period and chronic conditions require fewer treatments over a longer period

MassageSystematic manipulation of soft tissue

Therapeutic EffectsMechanical Responses

Occur as a direct result of pressures and movementsEncourages venous flow and mild stretching of superficial

tissuePhysiological Responses

Increases circulation aiding circulation, removal of metabolites, overcoming venostasis

Reflex effect - response to nerve impulses initiated through superficial contact Impacts body relaxation, stimulation, and increased

circulation

Relaxation can be induced by slow superficial stroking of skin

Stimulation achieved by quick brisk strokes, causing contraction of tissue Primarily psychological impacts

Increased circulation through reflexive and mechanical stimuli Capillary dilation, stimulation of cell metabolism,

decreasing toxins and increase lymphatic and venous circulation

Psychological ResponsesTactile system is one of the most sensitive systems

of the bodyBecause the laying on of hands is used w/ massage

it can be an important means of creating a bond of confidence between the athlete and the clinician

TapotementCupping

Produces invigorating and stimulating sensation

Series of percussion movements rapidly duplicated at a constant tempo

Hacking Used to treat heavy muscle areas, similar to cupping

Pincing Lifting of small amounts of tissue between thumb and first

finger in quick, gentle pinching movements

VibrationRapid movement that produces quivering or trembling

effect to tissueUsed to relax and soothe

Special ConsiderationsMake the patient comfortable

Positioning, padding, temperature, privacy

Develop confident, gentle approach to massageGood body positioning (clinician and athlete) an develop

good technique

Stroke towards heart to enhance lymphatic and venous drainage

Know when to avoid massageAcute conditions, skin conditions, areas where clots can

become dislodged

Sports MassageUsually confined to a specific area - rarely

given to full bodyFull body massage is time consuming,

generally not feasibleFive minute treatment can be effectiveMassage lubricants

Enables hands to slide and move easily over body, reducing friction

Rubbing dry area can irritate skinMediums include powder, lotion, oil or liniments

Positioning of AthleteArea must be easily accessible and must be relaxed

Exhibit Confidence

Ensure Patient Privacy and Athletic Trainer IntegrityDue to direct physical contact professionalism must be

maintained at all timesCritical when dealing with patient of opposite sexBe sure that area being treated is the only area

exposedAn additional athlete or athletic trainer should also be

present

Deep Transverse Friction MassageTransverse or Cyriax method used to treat muscle,

tendon, ligaments and joint capsulesGoal is mobilization of soft tissueGenerally precedes activityMovement is across the grain of the affected tissueAvoid treatment with acute injuriesTreatment will produce numbing effect allowing for

exercise mobilization

Acupressure MassageBased on Chinese art of acupuncturePhysiological explanation and effectiveness may be

based on pain modulation mechanismsClinician can utilize acupuncture points in treatmentLocate through measurement of electrical

impedance or palpationSmall circular motions are used to treat points

(pressure to tolerance of athlete = generally more pressure = more effective treatment)

Treatment time ranges from 1-5 minutesCan treat one or more points, working distal to

proximalWill produce dulling or numbing sensation w/ results

lasting from minutes to hours© 2011 McGraw-Hill Higher Education. All rights reserved

Magnet TherapyBecoming popular amongst

competitive and recreational athletes

Used in cases of musculoskeletal ailments

Limited research on magnetic therapy

Utilizes magnetic fields to physiologically impact bodyChange polarity of damaged cells, increase blood

flow, increase muscle strength and hormone secretion, increase cell division and enzyme activity, increase lymphatic flow and alter blood pH© 2011 McGraw-Hill Higher Education. All rights reserved

Recording Therapeutic Modality Treatments

Specifics of treatment should be recorded on original SOAP note, progress note and treatment log

Changes in treatment parameters and modalities should always be noted

Evidence-Based Data Regarding Therapeutic

Modality UseClinical effectiveness has yet to be established

for a variety of conditions

Often rely on efficacy generated by manufacturers rather than research

Minimal modality-related evidence-based information availableEvidence should be carefully questioned and

consideredBest evidence should be put into practice
