Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive therapy often incorporated in physiotherapy treatment that uses low-voltage electrical currents. It can be used to temporarily manage pain symptoms stemming from musculoskeletal conditions, postoperative discomfort, sports injuries, and chronic pain.
TENS involves the application of small electrodes placed around the area of pain or along specific nerve pathways. These electrical currents penetrate the skin and underlying tissues to stimulate nerves, while reducing pain perception. It is often applied following exercise therapy for about 10 minutes to mitigate the risk of a symptom flare-up. During the treatment, you'll typically feel a tingling or pulsing sensation in the area where the electrodes are placed.
When used correctly under the supervision of a physiotherapist, TENS can be a safe and effective therapeutic modality. However, there are some precautions to keep in mind, such as avoiding contact with eyes, on broken or irritated skin, or over areas with reduced sensation.
In conclusion, Transcutaneous Electrical Nerve Stimulation (TENS) is a widely used technique in physiotherapy to manage discomfort without medication or invasive procedures. It can be a valuable tool in helping people find temporary relief from various types of acute and chronic pain conditions, promoting recovery and enhancing well-being.
