Precautions should be taken when stimulation is used:
- After recent surgical procedure where muscle contraction may disrupt the healing process.
- After an acute trauma or fracture where there is a tendency to hemorrhage;
- Over the menstruating uterus;
- Where the sensory nerve damage has caused the loss of normal skin sensation
- We recommend to use electrical stimulation devices under medical supervision.
- Dependent upon government regulation, these devices may or may not require a medical prescription.
- Keep out of reach of children.
Some patients may experience skin irritation or hypersensitivity due to electrical stimulation or electrical conductive medium. The irritation can usually be reduced by using an alternative conductive medium, or alternate electrode placement.
Improper use of stimulation may result in skin irritation and burns beneath the electrodes.
- Powered electrical stimulators should not be used on patients with cardiac demand pacemakers.
- Powered electrical stimulators should not be applied over, or in proximity to, cancerous lesions.
- Powered electrical stimulators should not be used while driving, operating machinery or during any other activity in which involuntary muscle contraction may put the user at undue risk of injury.
- Stimulation should not be applied over the carotid sinus.
- Severe spasm of the laryngeal and/or pharyngeal muscles may occur when electrodes are placed over the neck or mouth.
- Stimulation should not be applied transcerebrally.
- Adequate precaution should be taken when treating patients with suspected heart problems or epilepsy.
- Caution should be exercised in the transthoracic application of powered electrical stimulators so that the introduction of electrical current into the heart does not cause arrhythmias.
- Stimulation should not be applied over swollen, infected, or inflamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis, varicose veins, etc.
- Persistent use of stimulation in the presence of skin irritation may be injurious.
- The safety of electrical stimulation for use during pregnancy has not been established.
- The long-term effects of chronic electrical stimulation are unknown.
- Powered electrical stimulators should be kept out of the reach of children.
- Simultaneous connection to RF surgery equipment can cause a burn.
- Operation near (e.g. 1m) short wave or micro wave therapy equipment can change the output values of the stimulator.
- Powered electrical stimulators may be effected by electromagnetic interference.
Also, other electrical equipment in close vicinity may be effected by powered electrical stimulators. If such effects are suspected either switch off the offending equipment or increase the distance between the effected equipment and that suspected of causing the interference, or shorten connecting leads.
