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 exploration perfor-
mance in stroke patients with neglect when the neck muscles, contralateral to
the lesion, were stimulated by vibration. 3 This effect stems from 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 out the therapy,
the corresponding stimulation point must be found on the contra-lesional, pos-
terior neck muscles, taking into account the contraindications (chapter 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 slowly guides the NOVAFON sound
wave device along the neck muscles at medium intensity. The patient sits on a
chair for the treatment. The correct 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 stim-
ulation time should be interrupted by a 5 minute break after 10 minutes. A total
of at least 15 treatment sessions are necessary to achieve a lasting effect. Stop
the treatment immediately if any side effects occur (see section 5).
