Which statement best differentiates H-Wave from TENS based on the described mechanisms?

• A. H-Wave uses distinct low- and high-frequency modes with specific physiological effects; TENS relies mainly on gate-control of pain
• B. H-Wave relies entirely on endorphin release; TENS relies on gate-control
• C. T-Wave uses ultrasound energy; H-Wave uses electrical energy
• D. H-Wave increases pain by stimulation; T-Wave decreases pain

Answer: (A)

The key idea is how these electrical modalities affect tissue and pain through different mechanisms. H-Wave therapy uses distinct low- and high-frequency modes, each with specific physiological effects. The low-frequency mode is described as promoting circulation, reducing edema, and supporting tissue healing, while the high-frequency mode produces a different neuromuscular or tissue response. TENS, on the other hand, primarily relieves pain by gate-control of pain: stimulating large-diameter A-beta fibers in the dorsal horn to inhibit transmission of nociceptive signals to the brain. Some TENS settings can also engage endogenous analgesia, but the main teaching is that gate-control is the primary mechanism. The other statements don’t fit because ultrasound energy is a separate modality from electrical stimulation, and describing H-Wave as increasing pain or claiming it relies exclusively on endorphin release isn’t aligned with these mechanisms.
