Study Notes
Voltage and Time
- V (t) represents the voltage as a function of time, meaning it changes with time.
- The amplitude (VP) is the maximum voltage that a sine wave can reach in either direction.
Frequency Conversion
- 2Ï€ is a constant that converts frequency from cycles (in hertz) to angular frequency (radians per second).
TENS Devices
- TENS devices typically measure energy in watts (W) and represent the amount of energy consumed or produced per unit of time.
- They are often used alongside other devices, such as electrodes, to provide pain relief.
- TENS devices can modulate the transmission of pain signals, providing temporary relief from various types of pain, including chronic pain, acute pain, and pain associated with muscle tension.
Pain Relief Mechanism
- Electrical pulses transmitted through TENS devices can interact with or block the transmission of pain signals to the brain, reducing pain perception.
- This is achieved by stimulating the nerves underneath the electrodes, which are applied to the skin.
