Final answer:
The average duration of relief with sensory (traditional) TENS typically ranges from 1 to 2 hours. This method involves using a TENS device to deliver low-voltage electrical currents to provide pain relief.
Step-by-step explanation:
The average duration of relief with sensory (traditional) TENS typically ranges from 1 to 2 hours. This method involves using a TENS device to deliver low-voltage electrical currents to the skin to provide pain relief. It works by stimulating the sensory nerves, which can help block pain signals from reaching the brain.
Sensory TENS is commonly used for acute pain episodes and usually provides immediate relief. However, the duration of relief can vary depending on the individual and the specific condition being treated. For some people, the relief may last less than 30 minutes, while for others, it may last 6-7 hours.
