4.1 Patient preparation and treatment performance
To perform safe and effective treatment procedure:
•make sure if there are no contraindications to perform the treatment,
•the patient should be placed in a comfortable position while providing relaxation of tissues in the treatment
area, the patient should be in lying position in case of treatment performed near the head,
•sitting or reclining position should be applied to patients with respiratory disorders or breathing difficulties,
•inform the patient about the possible feelings occurring during treatment procedure.
The treatment effectiveness depends on the choice of parameters to the current patient’s condition. The
patient’s condition changes over time. Its observation and assessment should take place before, during and
after therapy. Such an action is necessary for changing the parameters in order to adapt them to the actual
condition of the patient.
It is recommended to keep the records of treatment, including the parameters of the therapy, the area of
treatment, treatment technique, dose and symptoms after therapy. If the treatment does not generate the
intended effects, change of treatment parameters should be taken into consideration. It is necessary to
continuously update knowledge and follow literary activities in the scope of therapy.
When performing therapy, it is recommended to follow the guidelines given in the following section.
4.1.1 Ultrasound therapy
•Before the treatment it is necessary to check the efficiency of functioning of the equipment and to control
the cables and ultrasound head.
•It is necessary to explain to the patient the method of treatment and sensations during the treatment
(always painless).
•It is necessary to clean the skin (or soap or alcohol 70%) in the place of application. If skin is very hairy in
the place of treatment, it is necessary to shave it gently, cover the remaining parts of the body in order
to avoid undercooling.
•The position of the therapist should facilitate free access to the equipment in such a way that the
ultrasound head should remain for the whole time of treatment in contact with the skin of the patient.
Proper pressure is necessary in order to ensure firm contact between the skin and the head which enables
maximized transmission of ultrasound energy.
•It is necessary to use the medium conducting the ultrasounds, preferably gel.
•Coupling medium should be applied on the surface of skin, make continuous movements in the form of
overlapping or longitudinal circles, the head shall not be removed from skin, in case of pain or burning it
is necessary to stop therapy and change parameters.
•It is necessary to localize the tissue affected by the disease, determine its type, depth, which determines
the choice of frequency of ultrasounds (up to 6 cm frequency 1 MHz, up to 1 cm frequency 3,5 MHz),

4. Unit operation
page 17 of 30 issue date 06.11.2020, release 11.0
surrounding tissues, tissues repair phase (acute conditions – only mechanical operation of ultrasounds,
in chronic conditions mainly thermal effect), chose the method of application (direct, indirect), determine
proper exit position: without pain, relaxation position, treated tissues should be moved as close to the
surface of skin as possible.
•In direct therapy the head is moved in a continuous way, by exercising pressure, parallel to the skin, by
applying steady, rhythmical motion patterns at average speed of 4cm/s. Too fast motions cause too low
accumulation of ultrasound energy, too slow motions cause overheating of tissues in case of using higher
intensities of ultrasounds.
•Choice of the method of moving the head depends on the shape of treated surface. In case of treating
surfaces with irregular shape, motion pattern may appear as overlapping circles. This method requires
from the therapist to make circular motions of small diameter, the size of ultrasound head should be such
that the subsequent circular sliding motion overlaps the half of the previous motion.
•In case of treating larger, flat surfaces it is necessary to carry out longitudinal movements. This method
requires from the therapist carrying out sliding movement with the adequate rhythm and carrying out
side movements of length equal to half of the ultrasound head’s diameter. As far as possible it is
recommended to slightly press the head to the skin surface as this increases the penetration of
ultrasounds deep into the tissues.
•Even during treatment of relatively small areas, such as trigger points, elements of scars or tendons it is
necessary to make even very small but continuous movements with the head (often determined as semi-
stationary techniques).
•Ultrasounds in water bath are used if part of the body subjected to therapy is of irregular shape or there
is a spot sensitivity enabling direct contact with ultrasound head. Most often it is used in therapy of
palms, forearms, feet and ankles. Part of the body subjected to therapy should be immersed in degassed
water with temperature pleasant for the patient. Waterproof head must be placed at the distance of 1-2
cm and move parallel to the treated surface. Intensity must be increased by 30-50%, to obtain a dose like
in direct therapy.
•Output power must be switched on if the head is in direct contact with the skin and at the same time it
is in motion. Such a procedure allows to avoid damages to the converter and prevent skin injuries, which
may occur if a sufficient amount of energy is taken back to the head. Control system which monitors the
contact of the head reduces the output power, if the head’s contact is inadequate.
4.1.2 Laser therapy
•Prior to treatment it is necessary to explain to each patient the applicable safety rules during laser
therapy treatments. Prior to the treatment, the patient must wear properly matched protective goggles.
•Before the treatment it is necessary to check the efficiency of functioning of the equipment and to control
the laser applicators and the measurement of the output laser power according to 3.2.5.3
•Dose of radiation must be adapted to the goals of therapy. Therapeutic dose is described as energy
density and is expressed in J/cm2.
•Technical parameters of the equipment, that is the wave length and surface of an applicator, have direct
impact on the dose of radiation.
•Methods of application (point applicator – contact, cluster applicator – contact, contactless), scanning
(contactless) is adapted depending on the size of application area and the goal of therapy.
•It is necessary to follow the recommendations provided below when choosing energy density:
at the beginning of treatment series and in acute conditions it is necessary to use smaller doses up
to 4 J/cm2– it is always necessary to observe the reaction of the patient’s organism,
in chronic conditions – higher doses, above 4 J/cm2.
•In therapy it is allowed to use the following application techniques:
single point or several points within a given area (e.g. painful points or acupuncture points, wound
along the edges or within a small distance from the wound, within a knuckle);
grid method and scanning (large surfaces).
•In each technique it is necessary to ensure that the radiation beam is at right angle on the tissue.
