6 Intended use and intended user
Ultrasound therapy
Ultrasound is a mechanical energy consisting of high-frequency vibrations applied by means of an
ultrasound applicator. These vibrations pass through the tissue of the body and are gradually
absorbed and transformed into heat. The resulting temperature increase triggers biological changes
to occur in the tissue for the relief of pain, relaxation of muscle spasms and reduction of joint
contractures.
Electrotherapy
Pain Management
Pain Management is the use of electrical stimulation for pain relief.
Muscle Stimulation
Muscle Stimulation is the use of electrical stimulation to treat muscle dysfunction.
Combination therapy
Combination therapy is the combined application of ultrasound and electrical stimulation. With
combination therapy the metal surface of the ultrasound treatment head becomes the negative
electrical stimulation electrode, while the lead wire with the red connector remains the positive
electrical stimulation electrode. Combination therapy is available with all current waveforms, but
limited to channel 2. Combination therapy is typically used for the reduction of muscle spasm.
Intended user
The 4-series device is intended to be used, and shall only be used, by or under the supervision of
professional users in the field of physical therapy and rehabilitation, who understand the benefits and
limitations of electrotherapy and ultrasound therapy.
