Step 1: Understanding the types of electrical currents in therapy.
Monophasic sinusoidal currents are a type of alternating current used in physical therapy. Pierre Bernard introduced these currents as diadynamic currents for therapeutic use.
Step 2: Analyzing each option.
- (1) HVPGS (High Voltage Pulse Galvanic Stimulation): HVPGS refers to high-voltage, low-frequency current used in electrotherapy, but not the type introduced by Bernard.
- (2) Galvanic Current: This is a continuous direct current, different from sinusoidal or alternating currents.
- (3) Faradic Current: This type of current is typically used in muscle stimulation but is not the monophasic sinusoidal current introduced by Pierre Bernard.
- (4) Diadynamic Currents: Correct. Diadynamic currents are monophasic sinusoidal currents, a therapeutic form of current introduced by Pierre Bernard.
Step 3: Conclusion.
The correct answer is (4) Diadynamic Currents, as these are the currents introduced by Pierre Bernard.
