Abstract
A base for warming massage nodes of a hand-held therapeutic device includes a housing, terminals connectable to a power supply, a seat for seating the massage nodes, and a heating circuit positioned to provide heat proximate to the massage nodes when the massage nodes are seated in the seat. The massage nodes can comprise an outer layer of stainless steel or iron and a core of material other than or in addition to air. The core absorbs or retains heat for a preferably gradual release over time. A method for warming such massage nodes includes selectively disposing the massage nodes in the housing adjacent to a heater, energizing the heater, permitting the heater to warm the massage nodes, and separating the massage nodes from the heater. The massage nodes can be separated from the heater by a magnetic extraction using the hand-held therapeutic device.
