Which device is described as generating a mild current that yields a comfortable, non-fatiguing contraction?

• A. H-Wave
• B. TENS
• C. SAM
• D. Ultrasound therapy

Answer: (A)

The key idea here is identifying an electrical stimulation device whose design aims to produce a gentle, comfortable muscle contraction that does not fatigu e easily. The H-Wave device is described and used in practice as generating a mild current that yields a smooth, non-fatiguing contraction. This contrasts with other modalities: TENS is primarily for pain modulation and is not focused on triggering sustained, fatigue-resistant contractions; ultrasound therapy uses acoustic energy rather than electrical current to affect tissue and does not directly cause muscle contraction; SAM is another stimulation option but is not specifically characterized by delivering comfortable, long-lasting contractions in the same way. So, the option described as producing a mild, comfortable, non-fatiguing contraction aligns with the H-Wave approach.
