SAFETY MEASURES
• Do not apply stimulation near the area of an implant, such as cochlear, pacemakers,
skeletal or electrical.
• Do not apply stimulation in the vicinity of metal. Remove jewellery, body piercings,
buckles or any other removable metallic product or device in the area of stimulation.
• If pregnant or menstruating, do not place electrodes directly over the uterus or
connect pairs of electrodes across the abdomen.
• Do not use the One stimulator in water or in a humid atmosphere (sauna,
hydrotherapy, etc.).
• Do not use the One stimulator in an oxygen-rich atmosphere.
• Never carry out an initial stimulation session on a person who is standing. The first five
minutes of stimulation must always be performed on a person who is sitting or lying
down. In rare instances, very highly strung people may have a vagal reaction. This
is of psychological origin and is connected with a fear of the muscle
stimulation as well as surprise at seeing one of their muscle contracts without
having intentionally contracted it themselves. This vagal reaction produces a feeling
of weakness with a fainting tendency, slowing down of the heart rate and a reduction
in arterial blood pressure. If this does occur, all that is required is to stop the
stimulation and lie down with the legs raised for the time it takes for the feeling of
weakness to disappear (5 to 10 minutes).
• Never allow movement resulting from muscular contraction during a stimulation
session. You should always stimulate isometrically; this means that the extremities of
the limb in which a muscle is being stimulated must be firmly fixed, so as to prevent
the movement that results from contraction.
• Do not use the One stimulator if you are connected to a high-frequency surgical
instrument as this could cause skin irritation or burns under the electrodes.
• Do not use the One stimulator within one metre of short wave or microwave devices
as this could alter the currents generated by the stimulator. If you are in any doubt
as to the use of the stimulator close to another medical device, seek advice from the
manufacturer of the latter or from your doctor.
