PurposeTherapeutic ultrasound units convert electromag-

netic energy to high-frequency (i.e., 1 or 3 megahertz[MHz]) sound waves that penetrate tissues to producepain relief and facilitate tissue healing through ther-mal and nonthermal physiologic reactions. This con-version of energy occurs in the transducer, or sound ortreatment head, of the machine. Ultrasound as a mo-dality can be used independently or in conjunction with

a neuromuscular stimulator to enhance pain-reliefmechanisms and aid in the healing of soft-tissue injuries.

The exact physiologic mechanisms of pain relief andaccelerated tissue healing through local heating areunknown. Possibilities include increased local bloodflow, increased local metabolic rate, muscle relaxation,and heightened pain threshold of nerves. Conditionsinvolving scar-tissue tensions; ulcerations; bursitis; ormuscle, tendon, ligament, or joint pain can be treatedwith ultrasonic energy.

Similarly, the physiologic mechanisms of pain reliefand enhanced tissue healing through nonthermal ef-fects of ultrasound are still under debate. Some theories

propose that the increased release of analgesic chemi-cals or increased cell permeability to certain ions isresponsible. However, the most widely accepted expla-nation is acoustic streaming, which occurs in responseto mechanical pressure, in this case produced by theflow of ultrasonic energy. According to this theory, theenergy waves produced by the ultrasound transducercause extracellular fluids to move rapidly around thecell membrane, causing the cell to vibrate. The cellularvibrations produce gas-filled bubbles, a process knownas cavitation. For therapeutic purposes, the cavitationshould be stable: the bubbles should pulse but notexpand or burst. Stable cavitation leads to increasedcell permeability, which is believed to induce pain-re-lief mechanisms such as altered pain perceptions. Sta-ble cavitation is also believed to stimulate the releaseof collagen and increase platelet activity, which in turnspeeds the rate of healing. Transient cavitation isunstable and destructive to the cell and may result intissue damage. More research is needed to completelyunderstand the extent of nonthermal therapeutic ef-fects (Dyson 1987; Michlovitz 1996).

Principles of operationWhen tissues absorb energy, most of that energy is

converted into heat. Therapeutic ultrasound, a modal-ity used in the treatment of soft-tissue injuries, relieson a transducer to apply energy to the patient’s skinin the form of sound waves at frequencies well abovethose audible to the human ear. A frequency of 1 MHzis used for deep (3 to 5 cm) tissue, while a frequency of3 MHz is used for more superficial (1 to 2 cm) tissue.Ultrasonic energy is gradually absorbed and convertedto heat as it travels through the tissue; therefore, it ispossible to heat the underlying tissue without over-heating the skin itself. Muscle absorbs about twice asmuch ultrasonic energy as fat does; bone absorbs about10 times more than soft tissue does. In travelingthrough the first 3 cm of muscle, the ultrasonic beamretains about 50% of its surface intensity value, asatisfactory amount for deep heating. The rate atwhich tissue temperature increases when exposed tothe ultrasonic beam depends on the intensity (powerper unit area, expressed as watts/cm2) and local circu-lation, since blood will carry heat away from the area.

A therapeutic ultrasound unit has two basic compo-nents — a generator and a transducer. The electricaloutput of the generator is applied through a flexiblecable to a piezoelectric crystal in the transducer. Thecrystal converts electrical energy into acoustic energythrough the reverse piezoelectric effect: as the voltagealternates across the crystal, the crystal expands andcontracts, creating vibrations. This acoustic energyexits the transducer in a collimated beam pattern.

A special coupling gel or water is used to facilitatetransmission of the ultrasound beam from thetransducer to the patient’s skin. Some units are water-tight, allowing for underwater therapy. Not using gelor water, or using an inadequate amount, will causeheat at the transducer-skin interface instead of in theunderlying tissues, possibly burning the patient.

Most units allow selection of a continuous mode, inwhich the output power is constant, or a pulsed mode,in which the output is switched on and off; the pulserate is typically 60 to 120 pulses per second (pps),although some units operate at a higher or lower rate.Pulsed waves are further characterized by the dutycycle, the percentage of time that ultrasound waves arepresent during a pulsed period. Typical duty cyclesrange from 5% to 50%. Because the output power of apulsed waveform averaged over the on-and-off phaseof the cycle is lower, it causes less heating than acontinuous output on the same setting. This meansthat the pulsed setting has fewer thermal effects. Somestudies have associated a reduced healing time withpulsed ultrasound (Dyson 1987).

An important characteristic of the transducer is itsbeam nonuniformity ratio (BNR), which approximatesthe intensity across the transducer’s effective radiat-ing area (ERA) — the actual area of the transducerthat radiates ultrasound. The BNR is the ratio of themaximum point intensity on the transducer to theaverage intensity value across the transducer surface.Areas of high spatial intensities are known as “hotspots” and may cause excessive heating to the under-lying tissue. A lower BNR indicates a more even dis-tribution of energy from the transducer (see Fig. 1).

For correct application of ultrasound, thetransducer must be kept in constant motion, using

either a stroking motion or an overlapping circularmotion (Gann 1991; Michlovitz 1996). Stationary ap-plication can lead to a buildup of heat in one spot,causing a burn to the skin or to deeper tissue. It mayalso lead to the formation of standing waves, whereinthe incident wave and the waves reflected from thetissue interface in the body are superimposed on eachother so the peaks of both waves combine to eitherincrease the effect or cancel out the waves. Standingwaves can damage the tissues that surround the waveand may cause clots in smaller blood vessels (Dyson1987).

Since there is no direct indicator of internal tissuetemperature, the operator depends on patient feed-back to adjust the intensity of the treatment andprevent burns. The operator can, however, estimatethe output strength by knowing the ERA, the sound-wave frequency, and the length of treatment.

Some units have an automatic shutoff that discon-tinues therapy and stops the unit’s treatment timerwhen there is insufficient coupling between thetransducer and the patient; they can also have anaudible and/or visible alarm to alert the user to theproblem. Some units also accommodate the use of twotransducers at a time either to treat two separate areason one patient or to treat two patients at once. Inaddition, some suppliers offer watertight transducersfor use in underwater therapy.

A neuromuscular electrical stimulator is electricallysimilar to a transcutaneous electrical nerve stimula-tion (TENS) unit (see the Product Comparison titledSTIMULATORS, ELECTROANALGESIC, TRANSCUTANE-OUS ELECTRICAL NERVE). An electronic generatortransmits pulses of energy through the sound head,which acts as the active electrode, and into the tissue.Pulse waveforms are monophasic (either positive ornegative) or biphasic; typically, a biphasic waveform isused in conjunction with ultrasound therapy. Thepulse rate is variable; generally, 80 to 150 pps are usedtherapeutically. The pulse amplitude is adjusted sepa-rately for each modality, allowing the maximum bene-fit from both modalities while maintaining patientcomfort.

Neuromuscular stimulation produces some localthermal and chemical changes in the patient; however,it is most often used to create a muscle contraction.When electrical stimulation is used in conjunction withultrasound, the active electrode can be manipulated toproduce a rhythmic contraction-release episode in themuscle or muscle group that is most affected by theinjury. The contraction-release acts as a pump andpromotes the removal of metabolic by-products, whichhelps reduce spasm and pain.

Some neuromuscular stimulators are available asintegral components of therapeutic ultrasound unitsand can be used in conjunction with the ultrasound.Combined therapy has been found to be useful inpreventing scar tissue formation in healing tissues andin permitting the user to focus on particular muscletrigger points for greater pain relief (Roy and Irvin1983). However, there is much controversy about thevalidity of these studies, and very little supportingliterature has been published.

Reported problemsUltrasound output may decline over time. The in-

strument should be inspected annually and followingany mechanical impact to the transducer (e.g., fromdropping) to ensure satisfactory output calibration.The transducer assembly is prone to deterioration andshould be checked frequently for proper transmissionand watertightness.

There have been reports of patient burns during theuse of ultrasonic units. These include both internalburns, caused by excess local heating, and skin burns,

caused by contact with a hot transducer or heating ofthe skin-transducer interface due to inadequate gel.

The intensity levels of ultrasonic therapy are gener-ally much higher than those of diagnostic ultrasonicequipment. Clinicians should therefore be aware ofpotential hazards (e.g., areas of insufficient blood flowthat cannot handle the increased metabolic activitycaused by ultrasonic treatment) and use ultrasoundwith care. Inefficient coupling caused by poor design,a defective crystal, or an insufficient amount of gel willalso cause heat to build up in the transducer andthereby reduce the number of sound waves radiatedinto the treatment site.

Therapeutic ultrasound is contraindicated for use invarious areas: the eye; the uterus during pregnancy;the testes; malignant tumors; the spinal cord; andareas over the heart, a pacemaker, joint replacementswith polyethylene or methyl methacrylate (a commonglue type), prostheses, or epiphyseal (growth) plates inpatients under the age of 20. In addition, ultrasoundapplication may damage tissue that has been subjectedto deep radiation treatments.

Therapists administering ultrasound treatment arealso exposed to vibrations passed through the housingof the transducer as they hold the applicator. Thesevibrations, known as parasitic radiation, may causeacute pain in the hand and finger joints of some thera-pists (Michlovitz 1996).

Purchase considerationsA purchaser has the option of buying a tabletop,

wall-mounted, or cart-mounted therapeutic ultra-sound unit. Some portable devices are also available ina carrying case or tote bag if the unit is to be used foroff-site therapy.

Ultrasound units with dual frequencies (i.e., 1 and3 MHz) provide a greater range of treatment capabili-ties. Some therapy systems come with only onetransducer, while others are equipped with severaltransducers of various diameters to facilitate treat-ment of different areas of the body.

Although ultrasound machines are relatively inex-pensive, costs associated with the following must alsobe considered: additional transducers, coupling gel,service (inspections and repairs), and a therapist.

Instead of buying separate units, purchasers canobtain a combination ultrasound/neuromuscularstimulator unit to reduce costs. These units allow theuser to choose therapeutic ultrasound only, neuromus-cular stimulation only, or a combination of the two.

Stage of developmentTherapeutic ultrasound has been used clinically

since the 1940s. Currently, most units are of solid-state design with digital controls. In 1993, the U.S.Food and Drug Administration updated its perform-ance standard for ultrasonic physical therapy prod-ucts, which requires these units to have a powerindicator, an autoshutoff timer, and labels indicatingthe BNR and ERA of the transducer. Some manufac-turers have also incorporated features such as self-calibration, output power control in response to tissueloading, and automatic shutoff in case of an overheatedtransducer and/or inadequate coupling.

Studies are being done to evaluate ultrasound usein phonophoresis — a method of delivering medica-tion through the skin to the site where the effect isdesired. Although the technique is commonly used,Byl (1995) concluded that more carefully designedresearch is needed to improve the ability to provideeffective treatment.

About the chart specificationsThe following terms are used in the chart:

Maximum output, W: The maximum ultrasonic energyradiated by the transducer, expressed in watts.

Maximum intensity, W/cm2: The maximum energy ra-diated per unit area, expressed in watts per squarecentimeter.

Duty cycle, %: The pulse duration (time on) divided bythe entire pulse period (time on + time off).

Pulse rate, pps: The repetition frequency of waves,expressed in pulses per second.

BNR: The beam nonuniformity ratio, or ratio of themaximum to average intensity across thetransducer surface; a lower number indicates moreuniform output from the transducer.

Transducer, number: The number of transducers avail-able; one transducer is included in the price, and theothers are optional.



ERA, cm2: The effective radiating area of thetransducer, expressed in square centimeters.

Multifrequency capability: The ability of a dual-frequency unit’s transducer to emit both frequen-cies through the same treatment head.

Plug-in/hardwired: The transducer is either perma-nently wired or simply plugged into the unit.
