Transcutaneous Electrical Nerve Stimulation (TENS) and Electrical Muscle Stimulation (EMS) are both types of electrotherapy, but they serve different purposes:
1. TENS: This method is primarily used for pain relief. It works by sending low-voltage electrical impulses through the skin to nerve pathways, which helps to block or interrupt the pain signals being sent to the brain. TENS doesn’t cause muscles to contract and is typically used for managing both acute and chronic pain.
2. EMS: This technique is used to stimulate muscle contractions, essentially mimicking what happens when you exercise. It’s used to prevent muscle atrophy (muscle loss due to inactivity), enhance muscle strength, and help with muscle recovery and rehabilitation after injuries.
In summary, TENS is used to manage pain, while EMS is used to stimulate muscles. Both methods should be used under the guidance of a healthcare provider or trained professional.
