Same carrier as the machine bodywork rows (8–10) — mechanical force applied to tissue; human rather than machine delivery is a delivery form, not a new carrier. The half of the pair that does NOT log its dose.
Origin & lineage
Manual therapy / bodywork.
Claimed mechanism
Human-applied mechanical force (massage, acupressure, manipulation) to soft tissue.
Plausibility
Plausible; a real mechanical carrier with a modest evidence base.
Evidence — grade C
Same carrier as rows 8–10; human vs machine delivery is a delivery form, not a new carrier.
