Percussion Massage: Amplitude and Model Scope

Amplitude describes the travel of a repeated stroke, while speed describes how often that stroke occurs. Neither alone establishes the force delivered under contact or how the mechanism behaves when loaded. A speed setting also differs from a measured stroke frequency: three buttons or levels do not reveal a value in strokes per minute. The current catalog does not publish a model-specific percussion mechanism, stroke amplitude or percussion-rate range. T1 is sometimes relevant to a general massage-mechanism discussion because it has four heads and three speed levels, but its features describe rotary kneading and its function field identifies motor vibration. Those facts do not turn it into a massage gun.

A motor-driven head cannot be assumed to provide percussion because rotation, oscillation and linear reciprocation are different motions. The drive linkage and contact-head path determine what reaches the body. Even where a motor speed is known, that value need not equal the contact stroke rate; gearing or a linkage can change the relationship. T1's published ninety-six nodes and four heads describe its contact layout, not a linear stroke specification. The current record has no amplitude, loaded force or percussion-frequency field. For merchandising, this means a compact motorized scalp product should keep its documented action rather than inherit claims from a massage-gun category. The distinction also prevents a speed count from becoming an invented power rating.
