Abstract: A method for interpreting patient treatment results and data is described. The Method uses an electric chiropractic adjusting instrument and software program and preferably comprises the following steps of adjusting a spine of a patient using the electric chiropractic adjusting instrument; gathering electric chiropractic instrument adjustment thrust data, patient spine response to thrusts of the electric chiropractic adjustment instrument, and objective clinician findings; recording the electric chiropractic instrument adjustment thrust data, the patient spine response to the thrusts, and the objective clinician findings in a database; providing real time results and findings; and generating reports based on the thrust data, the patient spine response to the thrusts of the electric chiropractic adjustment instrument, and the objective clinician findings.

Abstract: A chiropractic adjusting instrument comprising a housing; thrust nose piece an impact head to contact a body, a preload switch plunger; a dampening spring; a solenoid having a core; a preload spring; a recoil spring; an electronic pulse system operatively connected to a power source to provide alternating current for energizing the solenoid to impart impulse energy from the core to the thrust nose piece which is reproducible and independent of the power source; and a trigger system for triggering the electronic pulse system comprising a switch activated by the preload switch plunger. Preferably, the chiropractic adjusting instrument includes one or more of the following: an intelligent universal AC power converter; optimized force-time waveform; pulse mode operation; a sensing device having a sense output and a suite of electromechanical components designed to promote reproducible dynamic force impulses and safe operation.

Abstract: Studies investigating posteroanterior (PA) forces in spinal stiffness assessment have shown relationships to spinal level, body type, and lumbar extensor muscle activity. Little objective evidence is available discerning variation in PA stiffness and its clinical significance. The aim of this prospective clinical study was to determine the stiffness index and neuromuscular characteristics of the asymptomatic and symptomatic low back. Twenty-two subject underwent physical examination and completed outcome VAS, Oswestry, and SF-36 questionnaires. A hand-held spinal manipulation instrument, equipped with a load cell and accelerometer was used to deliver high rate (<0.1 sec) PA manipulative thrusts (450 N) to several common spinal landmarks including the posterior superior iliac spine (PSIS), sacral base, and L5, L4, L2, T12, T8 spinous (SP) and transverse processes (TP).
