The Effects of Tens for Phantom Limb Pain

Transcutaneous electrical nerve stimulation (TENS) is a form of pain control that may be used to help alleviate pain associated with phantom limbs. It is a safe and drug-free way to help relive discomfort caused by the feeling that an amputated limb is still present. This may include pain, itch or irritation of a missing bodily organ.

  1. What is TENS?

    • Transcutaneous electrical nerve stimulation is a form of pain control. TENS, as it is often called, is a small battery-powered device which can be applied to an affected area to deliver momentary pain relief. TENS shoots small, harmless electrical impulses into the body through patches containing tiny electrodes. The electrodes contain wires which receive the signal and help deliver pain relief. TENS can be used for acute pain management, such as while recovering from an injury or surgical procedure. It can also be used to help treat chronic pain due to arthritis or muscle pain.

    Phantom Limb Pain

    • Phantom limb pain or sensation is a medical condition in which a person who has undergone the amputation of a limb or body part may continue to experience sensation in the lost part. This phenomenon was first documented by a French military surgeon named Ambroise Paré (1510--1590). Phantom limb pain occurs as the part of the brain that once controlled the amputated body part continues to try to perform its usual duties. Though neurological in nature, this condition is quite common among recent victims of amputation.

    Treatment with TENS

    • Though traditionally treated with standard pain killers, phantom limb pain can be controlled through the use of TENS. The primary advantage of TENS is that--since it is not a drug--there are no side effects or risk of addiction. The use of TENS on an amputated limb involves placing an electrode patch onto the stump. As pain or sensation occurs, the TENS unit may be placed against the electrode and the patient may receive temporary relief from pain or sensation. The long-term goal of TENS is to stimulate the nerves surrounding the stump to help dispel the central nervous system's confusion regarding the missing limb or body part.

    Warnings On The Use Of TENS

    • TENS electrodes should only be applied where the skin is healthy and has normal sensation. They should not be used anywhere that skin is numb or broken. If an amputated limb does not have regular sensation or has open wounds which may still be in the process of healing, do not attach electrodes. Consult a doctor about the best point of contact for a TENS device. Using a TENS over an area of numb or sensitivity-deprived skin may result in the operator applying too much intensity and may cause minor burns. There are no known side effects of using TENS and long-term use has not been deemed harmful.

    Availability

    • TENS units are available through numerous suppliers of medical products. They can be purchased online or ordered through your doctor. Prices vary depending on models, but tend to cost between $100 and $170 dollars on average.
