device must be switched off for 15 minutes after 20 minutes of use
in order to avoid overheating. When treating very painful or sensitive
parts of the body (e.g. face, neck, head), the duration of application
should be reduced and adjusted to suit the patient's personal re-
quirements.
NOTE: Application of liniments (medicated topical preparations):
Generally, only apply small amounts of creams, ointments, cosmetic
or medicated liniments on the skin or place a fine cloth between the
device and the skin. Do not allow liquids or residues to penetrate the
NOVAFON device so as not to damage it.
4.2. PROFESSIONAL APPLICATION IN NEUROREHABILITATION
NOTE: The use of local vibration therapy for neurological diseases
should only be carried out by specialists (therapists, physicians,
nurses) or after detailed instruction by such a person.
4.2.1. Spasticity
Spasticity is a common consequence of a stroke and other disor-
ders of the central and peripheral nervous system. Local vibration
therapy, combined with physiotherapy, provides a simple and drug-
free treatment method. Numerous studies have shown a reduction
in spasticity as well as improved motor control and function. 2 The
effectiveness mechanisms are the tonic vibrational reflex and the
stimulation of the sensomotoric system. Taking into account the
contraindications (section 5), the spastic muscle itself is treated
at 50 Hz and the antagonist of the spastic muscle at 100 Hz. The
starting point can be on the tendon or directly on the muscle itself.
The treatment may be local, i.e. focusing on one point, or in sweep-
ing movements. The application with the NOVAFON device should
not exceed 20 minutes per unit. The treatment can be performed
up to 5 times a week. Please keep in mind that using the appliance
incorrectly can lead to increased muscle tone. Stop the treatment
immediately if any side effects occur (see section 5).
4.2.2. Hemineglect
Several studies have found an improvement in the visual explora-
tion performance of stroke patients with Hemineglect when the neck
musculature contralateral to the lesion is stimulated by vibration. 3
This effect is based on the fact that the vibration stimulates stretch
receptors in muscles and tendons of the neck, leading to an apparent
rotation of the head. For successful therapy, the corresponding stim-
ulation point must be found on the contralesional, posterior neck
muscles, taking into account the contraindications (section 5). This
point is determined by fixing a bright spot on the wall (e.g. by means
of a laser pointer) in a darkened room. The therapist guides the
NOVAFON device slowly along the neck muscles at 100 Hz and me-
dium intensity. The patient sits on a chair for the treatment. The cor-
rect stimulation point is determined as soon as the patient reports
that the fixed point is moving without moving his/her head. The total
treatment time should not exceed 40 minutes, whereby the pure
stimulation time should be interrupted by a 5 minute break after 10
minutes. A total of at least 15 treatment sessions are necessary to
