More than a dozen raised contact points, each one concentrating Therabot's force into a smaller surface area. If you've ever used a rumble roller or dug your knuckles into a stubborn quad, this is that — on autopilot. As the Node moves across your leg, each contact point creates a constantly shifting pressure pattern that works across muscle fibers rather than just compressing them flat. The effect is a rolling, kneading sensation that keeps the tissue responding instead of bracing against a single sustained load. Comes as a set of 3 — one for each of Therabot's massage nodes. Best for: Quads, IT band, calves, hamstrings — larger muscle groups where you want broad-but-intense coverage. The feeling: Like a deep tissue massage where the therapist uses their knuckles across the full width of the muscle. Intensity: High. Start at moderate expansion and work up. The nodes do a lot of the work for you.
