The Impulse iQ Adjusting Instrument is intended for chiropractic adjustment, mobilization, or manipulation of the musculoskeletal joints of the spine and/or extremities, or for soft-tissue musculoskeletal mobilization by a licensed health care professional only. For external use only.

The Impulse iQ Adjusting Instrument is a hand-held electromechanical chiropractic adjusting instrument. The device has three force settings (low, medium, high), a preload-control indicator light that turns from red to green upon achieving the proper preload, and an internal accelerometer to provide closed-loop feedback controlling thrust pulse rate. The device is only intended for use from a health care professional licensed by the law of the state that he or she practices.

Impulse "" (aka Neuromechanical™, aka CBP®) Adjusting Instrument is a hand-held electromechanical chiropractic adjusting instrument intended to be used for chiropractic adjustment or manipulation/mobilization of the joints of the spine and extremities. The device is only intended for use from a health care professional licensed by the law of the state that he or she practices. The instrument's shaft measures approximately 15 cm in length and 3.5 cm in width. The instrument's handle is rigidly attached to the shaft and measures approximately 10 cm in length. The external housing of the device consists of high impact plastic that surrounds its main internal components. The major external components of the device consist of the instrument's shaft, handle, force adjustment switch, trigger, preload control nose, stylus and power cord. Three types of interchangeable stainless steel stylus' attach to the preload control nose which make contact with the patient by means of a neoprene rubber end. The major internal components of the device consist of a circuit board, power supply, internal thrust element, solenoid, internal spring. Both external and internal views of the device are shown in Figure 1. Stylus specifications are shown in Figure 2, illustrating the three kinds of stylus', a single stylus, and two double contact stylus' that allows for dual contact to each side of the spine simultaneously. These styluses have been designed for appropriate anatomical contact with the spine. The instrument is manually triggered by the operator and contains a safety mechanism consisting of a triggering mechanism that does not allow for activation of the device unless the preload control spring is maximally compressed. In this manner, the clinician (operator) is able to test the patient's tolerance to contact prior to the instrument being able to be activated. The device is equipped with a force adjustment switch which allows for control of force produced by the instrument, high, medium, and low, representing transmitted peak forces of 265 N, 150 N, and 50 N respectively. Peak forces for all three settings are delivered in less than 5 ms. The device is operated in the following manner. After locating the target area to be treated the rubber end of the stylus makes contact with the treatment location. An approximate 15 N of preload force compresses the spring allowing for activation of the instrument's trieger mechanism. The operator is then able to manually trigger the device to deliver a single thrust ranging from 50 - 265 N depending on the force setting used.
