points near the painful area. In case of uncertainty, please consult your treating
physician or therapist regarding your individual application. The NOVAFON can
be used directly on the skin or through fabric/clothing. During the application,
make sure that the sound wave device glides gently and without pressure over
the body area. Use the entire surface of the attachment. This is the only way
the penetration depth effect of the NOVAFON can be fully deployed and the vi-
brations are transmitted optimally. Use only the NOVAFON's own weight for a
comfortable application.
The therapeutic application should not exceed a maximum of two 20-minute
treatment units per day. Please note that the NOVAFON must be switched off
for 15 minutes after using it for 20 minutes in order to avoid overheating. When
applied to sensitive areas (e.g. face, neck, head) or severely painful body parts,
the duration of application duration should be reduced and adjusted to accom-
modate the individual needs.
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 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 sequence of stroke and other disorders
of the central and peripheral nervous system. Local vibration therapy, combined
with physiotherapy, provides a simple and drug-free treatment method. A vari-
ety of studies demonstrated a reduction in spasticity as well as improved motor
control and function. 2 The mechanisms of effectiveness are the tonic vibration
reflex and the excitation of the sensorimotor cortex. Taking into account the
contraindications (chapter 5), the spastic muscle itself (flexors) is treated with
50 Hz (level 2) and the antagonist of the spastic muscle (extensors) with 100 Hz
(level 1). The starting point can be directly on the tendon or on the muscle. It
may be treated locally, i.e. focus on one point, or in sweeping movements. The
application with the NOVAFON sound wave 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. Neglect Several studies have shown an improvement in the visual ex-
ploration performance in stroke patients with neglect when the neck muscles,
contralateral to the lesion, were stimulated by vibration. This effect stems from
3
the fact that the stretch receptors in the muscles and tendons of the neck are
stimulated by vibration, resulting in an apparent rotation of the head. To carry
