Claim 10:
11. A method of using a percussive therapy device that includes a housing, an electrical source, a motor comprising a motor shaft and positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to provide reciprocating motion in response to activation of the motor, a massage attachment secured to a distal end of the push rod assembly, and a variable amplitude assembly that includes an eccentric weight member received on the motor shaft of the motor, the method comprising steps of:
(a) activating the motor and massaging a body part with the massage attachment, wherein the distal end of the push rod assembly reciprocates within a first range;
(b) adjusting an amplitude of the reciprocation; and
(c) activating the motor and massaging the body part with the massage attachment,
wherein the distal end of the push rod assembly reciprocates within a second range,
wherein the second range is different than the first range, and
wherein a rotational axis of the motor and a rotational axis of the variable amplitude assembly are aligned with each other,
wherein the variable amplitude assembly includes a movable member that is movable with respect to the eccentric weight member between a first position and a second position,
wherein the movable member includes an offset shaft extending therefrom,
wherein the push rod assembly is operatively connected to the offset shaft,
wherein the distal end of the push rod assembly reciprocates within the first range when the movable member is in the first position,
wherein the distal end of the push rod assembly reciprocates within the second range when the movable member is in the second position,
wherein a slot is defined in the eccentric weight member,
wherein the movable member includes a main body portion with a slide member extending therefrom, and
wherein the slide member is received in and movable within the slot.
