ABSTRACT:
A control system for a chiropractic adjustment instrument comprising a microprocessor programmable to control various parameters of an adjustor head to be driven against the spinal vertebrate of a patient. A solenoid is associated with the adjustor head which is energized by a capacitor. The capacitor is charged by a charging circuit to the programmed voltage level. The pressure of the adjustor head against the patient is sensed and when the pressure reaches a predetermined level, the capacitor is discharged to the solenoid to drive the adjustor head against the spinal vertebrate of the patient.
