Physical therapists have a wide variety of therapeutic tools and technologies at their disposal to help aid in your recovery process. One that is commonly used in treatment is electrical stimulation (e-stim). There are many types of e-stim used that serve different purposes depending on the condition being treated and the intended goal of its use. Transcutaneous electrical nerve stimulation (TENS) is a type that is particularly effective for pain relief, making it great for use in physical therapy clinics. But how exactly does it work?
The Science Behind TENS
TENS is administered by placing electrode pads onto the skin in the desired treatment area. The pads are connected to a device that is able to deliver low voltage electrical current to the area. Scientists believe that these electrical impulses alter the way that you perceive pain by stimulating nerves to block or reduce pain signals traveling to the brain. It is also theorized that the stimulation increases the body’s level of endorphins (“feel good” chemicals that are the body’s natural painkillers), which in turn blocks or reduces your pain perception. This allows TENS to be used in cases of both long and short-term pain. It has been found that pain relief can last up to 24 hours after treatment.
Can TENS Help Me?
TENS can be helpful in treating numerous conditions and injuries including, but not limited to:
- Arthritis
- Low back pain
- Tendinitis
- Neck pain
- Knee pain
- Bursitis
- Fibromyalgia
- Diabetic neuropathy
As with all rehab technologies, there are potential risks associated with TENS. They include electrical burns at the site of the pad, allergic reactions to the pads, and a general feeling of discomfort with the sensation that the current creates. However, these unwanted side effects are rare. TENS is non-invasive and has been shown to be a generally safe treatment option for those experiencing pain, especially in comparison to prescription pain relief medications. Always consult with your doctor or healthcare professional before starting treatment, as there are certain conditions in which TENS should not be used, such as pregnancy or cancer.
TENS is not a cure for pain, but instead a short term solution to provide pain relief. As a result, it cannot be effectively used as a stand alone treatment. Physical therapy is a conservative treatment option that can help in the reduction and management of pain by addressing the underlying impairments through stretching and strengthening exercises, manual therapy, and use of therapies such as e-stim. When paired with physical therapy, TENS can help to optimize recovery and pain relief.
