Study Notes

TENS Pulse Waveform

  • Typical feature of TENS pulse waveform: asymmetrical, biphasic, or monophasic waveform

Pulse Amplitude for TENS

  • Typical range of pulse amplitude for TENS: 10-80 mA

Interferential Therapy (IFT)

  • Basic principle of Interferential Therapy (IFT): to stimulate areas of the body using medium frequency currents, resulting in a deeper tissue penetration and reduced discomfort

Denervated Muscle Stimulation

  • Type of Denervated muscle stimulation: Surge Wave

Types of TENS

  • Pulse pattern for Conventional TENS: high frequency, low intensity, and high pulse width
  • Pulse pattern for Acupuncture-like TENS: low frequency, high intensity, and low pulse width
  • Pulse pattern for Burst TENS: packages of pulses at high frequency and low intensity
