TENS ( transcutaneous electrical nerve stimulation )
There are two different types of resort;
- Conventional / high frequency TENS
- AL-TENS which is more similar to acupuncture
TENS should always be the first choice when to relieve pain with TENS. AL-TENS use is primarily in patients with pain from several areas of the body and when it does not work or you do not get any results with conventional / high-frequency TENS.
Explanation Model Conventional TENS
Conventional TENS pain inhibitory effect is explained by the so-called “Gate Control” theory, that is, to drive out the flow of incoming / afferent input to the spinal cord. This means that the body can not register the same number of inbound / afferent pain signals in the spinal cord.
You usually get the immediate effect of TENS after completion of treatment, and it occurs only locally, where electrodes are applied. Often experienced pain relief and treatment very komfortabeI. At best, it is the effect of treatment in a single hour.
Comment Conventional TENS
In acute low back pain should be borne in mind that, muscle turned arisen for a reason. It can, for example be a structural damage in the area which muscle turned trying to protect or defend against.
Explanation Model AL-TENS
AL TENS pain inhibitory effect occurs unlike conventional throughout the body. It is not as efficient, but it works so that it activates the body’s overall pain inhibitory systems. This is envisaged will be able to provide an increased release of painkilling hormones such as endorphins. The advantage of the AL TENS is that the pain inhibitory effect lasts about 3-5 hours after a treatment session.
Treatment with conventional TENS
The frequency should be between 80-100Hz with a fastid on 100-150uS. Though time may be lower if you do not want a muscle in the treatment of pain relief.
When selecting the intensity / current, it is important to know that it is highly individual. It should not be perceived as painful or uncomfortable, but depending on whether such Patient has little muscle, much subcutaneous fat, old age and so on. In particular, these factors determine how high intensity / power which may be required. One should keep in mind that the body slowly adapts to the current which means that you must continually increase the strength of the power to achieve the same effect.
Placement of the electrodes should preferably be over the painful area. If you do not achieve any results with it so one can imagine placing proximal to the same segment, the adjacent segments or segmental spinal cord level. There is no limitation on the duration of use of TENS. Thus, one can treat the 24h / day and it is also why it can be good to have a machine to lend during the acute phase.
Treatment with AL-TENS
The frequency should be between 2-5Hz with a fastid on 150-250uS. When selecting the intensity / power, then you want to AL-TENS see a clear contraction. After a while, you choose to raise the intensity / power.
Placement of the electrodes is carried on a motor point of the major muscle groups, ie the muscle where it feels painful. One treatment takes place in about 20-30 minutes for it to begin to take effect.
Indications for treatment with TENS
Common indications for treatment with TENS can be:
- Pain of the musculoskeletal system
- Increasing circulation in the area
- Recovery after exercise / game / work
- Enable / train the muscles, for example until a peripheral nerve injury healed
Contraindications for treatment with TENS
Common contraindications for TENS can be:
- Pacemakers and other cardiac implants.
- Pregnant. Especially during the first 3 months of pregnancy and then not above the stomach.
- The neck, and not close to the carotid arteries. This is because the carotid body is a chemoreceptor mainly records the arterial blood, partial pressure and syrenivån- and carbon dioxide level in the blood. It is also sensitive to changes in pH and temperature.
