Abstract
A chiropractic adjustment tool or tapper comprises a housing, the housing having an open end; a striker assembly disposed within the housing and secured thereto; and a plunger device or plunger disposed externally to the housing and secured thereto, the plunger being in communication with the striker assembly through the open end in the housing. The striker assembly comprises a reciprocating striking rod. A power source, such as a pneumatic motor, electric motor, solenoid arrangement, or the like, provides power through a series of gears and springs to move the striking rod in reciprocating fashion. The plunger comprises a plunging rod slidable within a body. Once each cycle, the striking rod strikes the plunging rod, which moves away from the striking rod and strikes the patient's body. Upon striking the patient's body, another spring retracts the plunging rod until it once again contacts the striking rod and is again forced against the patient's body. A typical rate of impact is thirty impacts per second, though other rates of impact are available and can be efficacious as well. Both the speed and the force of impact are adjustable to provide optimal therapeutic effects.
