Which current type is linked to tetanic contraction in the material?

Explanation:
Tetanic contraction happens when stimulation is delivered fast enough that individual muscle twitches fuse into a single, continuous contraction. The current type described as low frequency is the one that, with the device’s pulse duration and duty cycle, produces this rapid enough volley of impulses to summate into a sustained contraction. Higher frequency currents tend to produce different responses (more heating or sensory effects) and don’t produce the same clean fused contraction in this context. So the low-frequency current is the type linked to tetanic contraction.
