ABOUT СОДЕРЖАНИЕ ULTRASOUND THERAPY
Intelect® Mobile Ultrasound
OVERVIEW OF ULTRASOUND THERAPY Utilizing ultrasound waves through muscle, nerve, and connective tissue has been well documented as effective in reducing pain, muscle spasms, and joint contractures. There are several items that affect the penetration of ultrasound on the target tissues. Please refer to the documentation as a reference on the appropriate frequency for your clinical needs. There are four sound heads available with the Intelect Mobile Ultrasound System: 1 cm2, 2 cm2, 5 cm2, and 10 cm2. Select either 1 or 3 MHz frequencies for each applicator (only 3.3 MHz is available with the 1 cm2 sound head). Frequency may be selected either before or during therapy.
Common Terms Applicator - The hand held assembly used to deliver ultrasonic energy. The applicator includes the sound head, transducer, and related electronics. Beam Non-Uniformity Ratio (BNR) – By nature, an ultrasound beam is not homogeneous. The BNR is a ratio of the highest intensity found in the beam field to the average intensity as indicated on the output display of the unit. This measure may not exceed 5.0:1. Because of the areas of increased intensity, the sound head is moved continuously during the treatment. Collimating (Coll)- The shape of the ultrasound beam. While neither focused nor dispersed, this ultrasound beam resembles a column when applied from the unit through the sound head. Continuous Mode – The output of the ultrasound is not interrupted during the treatment time. This mode imparts the most energy to the tissues and is used when a maximal effect is desired. (See Duty Cycle). Coupling Media – An agent used to insure that the ultrasound is transmitted from the sound head to the tissue to be treated. Gels or lotions labeled for therapeutic ultrasound use are recommended. 7
ABOUT ULTRASOUND THERAPY
Intelect® Mobile Ultrasound
OVERVIEW OF ULTRASOUND THERAPY - COMMON TERMS (CONTINUED) Duty Cycle – This is the ratio of the “On” time to “Total” time of the cycle, expressed as a percentage. The duty cycle describes the pulsed modes of ultrasound. The lower the percentage, the lower temporal average intensity. 100% is continuous ultrasound. Effective Radiating Area (ERA) – A measure of the ultrasound beam made underwater, 5 mm from the radiating surface of the sound head. The ERA is always smaller than the geometric area of the sound head, but should be as close as possible. This measurement is used to calculate the ultrasound intensity in W/cm2. Frequency (Freq) – Selectable to 1 or 3 MHz with the 1 cm2, 2 cm2, 5 cm2, or 10 cm2 sound head (only 3.3 MHz is available with the 1 cm2 sound head). The lower the frequency, the longer the wavelength, the deeper the penetration of ultrasound. Lead Zirconate Titanate – A synthetic crystal used to create the ultrasound beam by vibrating 1,000,000 (1 MHz) or 3,000,000 (3 MHz) times per second. This type of crystal is both durable and efficient in its functions. Power – A measure of the intensity of the ultrasound delivered to the patient. Unit of measure is watts (W). Pulse Duration – Refers to the amount of time the ultrasound is being delivered in the pulsed mode. For example, in the 20% duty cycle mode, the ultrasound is delivered for 2 msec and off for 8 msec (at 100 Hz) throughout the treatment period. Pulse Frequency – The pulse frequency is the number of pulses per second and is expressed in hertz. The available pulse frequencies on the Intelect Mobile Ultrasound are 16, 48, and 100 Hz. Pulsed Mode – The output of the ultrasound is automatically interrupted during the treatment time. This limits the amount of energy delivered to the tissues. Sound Head – The aluminum face of the applicator that contacts the patient’s skin. It covers a transducer mechanism that converts electrical energy to mechanical energy in the form of a vibrating crystal. 8

OVERVIEW OF ULTRASOUND THERAPY - COMMON TERMS (CONTINUED) Ultrasound Intensity – Ultrasound power delivered to the patient expressed in total power as watts (W) or in terms of the sound head’s effective radiating area, watts per centimeter squared (W/cm2).
Description of Ultrasonic Field The spatial distribution of the radiated field is essentially a collimated beam of the ultrasonic energy having a cross-sectional area of 8.5 cm2 for the 10 cm2 sound head when measured at a point 5 mm from the transducer face. The energy distribution within the radiated field is 3.0 W/cm2 maximum and it takes a generally conic shape, having decreasing intensity at progressively increasing distance from the face of the transducer. This field distribution applies for the radiation emitted into the equivalent of an infinite medium of distilled, degassed water at 30 °C and with the line voltage variations in the range of 10% of the rated line voltage.

DANGER
Potential for Burns It is possible for ultrasound therapy to cause burns if the therapy is not performed properly. Skin burns can result from one or more of the following: • If the intensity (power) is too high. • If you are using too low a frequency. • Using a stationary technique (holding the sound head in one place). • Moving the sound head too slowly. • Treating an area with sensory nerve damage (or the loss of normal skin sensations). • Desensitized areas can be overheated or burned without the patient’s knowledge. Use extreme caution with these patients (e.g., diabetes, neural damage, etc.). • Bony prominences are especially vulnerable: they reflect sound waves and increase intensity to the periosteum.
Patients with an implanted neurostimulation device must not be treated with or be in close proximity to any shortwave diathermy, microwave diathermy, therapeutic ultrasound diathermy or laser diathermy anywhere on their body. Energy from diathermy (shortwave, microwave, ultrasound and laser) can be transferred through the implanted neurostimulation system, can cause tissue damage and can result in severe injury or death. Injury, damage or death can occur during diathermy therapy even if the implanted neurostimulation system is turned "off."

ABOUT ULTRASOUND THERAPY
Intelect® Mobile Ultrasound
Preventing Overheating of the Sound Heads
Patient Susceptibility
To prevent the sound head from becoming overheated, do the following: • Check to be sure proper contact is being made throughout the treatment. • When treating in water, make sure that the sound head is completely under water. • For direct coupling, you may need to apply more conductive gel or lotion during the treatment to achieve better coupling. • You can also reduce the power or duty cycle during the treatment if you are treating an area where it is difficult to obtain good coupling.
Some patients are more sensitive to ultrasound output and may experience a reaction similar to a heat rash. Be sure to inspect the treatment area during and following treatment, and discontinue if an adverse reaction does occur.
Output Power Choose a lower watt setting to reduce output or select a pulsed duty cycle. Higher output levels have a greater potential for patient discomfort.
Coupling Coupling is described as contact between the sound head and the treatment site and may be accomplished through the use of a coupling agent, such as gel, lotion or water (underwater treatments only). Anything used as a coupling agent must be highly conductive. Air is a very poor conductor of ultrasonic waves.
Preventing Adverse Effects Perform the following procedures to avoid the negative effects of ultrasound therapy.
Sound Head Movement
Head Max. Temp. Disclaimer
If movement of the sound head is too slow, the patient may feel periosteal pain characterized by a deep ache or pain. If motion is too fast, or if the sound head does not maintain good contact with the skin, the therapeutic effect of the sound waves will be reduced and the sound head may overheat.
Head Max. Temp. is for the protection of the equipment, not for the protection of the patient.
