Comfort; Submotor

What is the Mechanism of Action for Conventional TENS (High Frequency, P2)?

Gate theory

What is the intensity level for Burst TENS?

Medium to High- (rhythmic muscular contraction)

What is the Mechanism of Action for Burst TENS (P1)?

Endogenous Opiate

What is the Mechanism of Action for Brief-intense TENS? (P2)

Endogenous Opiate; Gate

For Interferential Current (IFC) what sensation is associated with the sensory level (P3)?

Pain

For Interferential Current (IFC) what mechanism of action is triggered with the sensory level (P3) setting?

Gate Theory

For Interferential Current (IFC) what condition is treated with the sensory to motor level (P1)?

Muscle spasm

What are the potential mechanisms of action when using IFC for sensory and/or motor stimulation?

Gate (P3) OR Endogenous Opiate (P1)

What is the main characteristic of Program 4 in IFC?

Fully programmable/manual setting
