Adjusting Instrument Research part 5: Impulse VS Activator
The forces and time profile of the electromechanical devices resulted in a more uniform and greater energy dynamic frequency response in comparison to the spring-loaded mechanical adjusting instruments. #electromechanical #impulse #adjusting #instrument has better force time #acceleration than the… Click To Tweet OBJECTIVE: To quantify the force-time and force-delivery characteristics of six commonly used handheld chiropractic adjusting devices. METHODS: Four spring-loaded instruments, the Activator Adjusting Instrument; Activator II Adjusting Instrument, Activator III Adjusting Instrument, and Activator IV Adjusting Instrument, and two electromechanical devices, the Harrison Handheld Adjusting Instrument and Neuromechanical Impulse Adjusting Instrument, were applied to a dynamic load cell. A total of 10 force-time histories were obtained at each of three force excursion settings (minimum to maximum) for each of the six adjusting instruments at preload of approximately 20 N. RESULTS: The minimum-to-maximum force excursion settings for the...
Read MoreAdjusting Instrument Research part 4: Multiple Thrusts, More Spinal Motion
Impulse brand adjusting instrument have found that multiple impulse thrusts create more intersegmental spinal motion. Increased multiaxial lumbar spinal motion responses during multiple-impulse mechanical force manually assisted spinal manipulation. multiple #thrusts by #impulse #adjusting #instruments create more #spinalMotion Click To Tweet BACKGROUND: Spinal manipulation has been found to create demonstrable segmental and intersegmental spinal motion thought to be biomechanically related to its mechanisms. In the case of impulsive-type instrument device comparisons, significant differences in the force-time characteristics and concomitant motion responses of spinal manipulative instruments have been reported, but studies investigating the response to multiple thrusts (multiple impulse trains) have not been conducted. The purpose of this study was to determine multi-axial segmental and intersegmental spinal motion responses of ovine lumbar vertebrae to single impulse and multiple impulse spinal manipulative thrusts (SMTs). METHODS: Fifteen adolescent Merino sheep were examined....

Impulse adjusting instrument caused linear increase in both force and spinal motion response Adjusting instrument (Impulse vs Activator) resulted in the greatest acceleration and displacement responses #impulse #adjusting #instrument creates more #spinal #acceleration Click To Tweet Three-dimensional vertebral motions produced by mechanical force spinal manipulation. OBJECTIVE: The aim of this study was to quantify and compare the 3-dimensional intersegmental motion responses produced by 3 commonly used chiropractic adjusting instruments. METHODS: Six adolescent Merino sheep were examined at the Institute for Medical and Veterinary Science, Adelaide, Australia. In all animals, triaxial accelerometers were attached to intraosseous pins rigidly fixed to the L1 and L2 spinous processes under fluoroscopic guidance. Three handheld mechanical force chiropractic adjusting instruments (Chiropractic Adjusting Tool [CAT], Activator Adjusting Instrument IV [Activator IV], and the Impulse Adjusting Instrument [Impulse]) were used to randomly apply posteroanterior (PA) spinal...

Validation of the force and frequency characteristics of the activator adjusting instrument This study uses an accelerometer to measure the force frequency which just means we can measure spinal motion based on the strength of the Activator Adjusting Instrument OBJECTIVE: To determine the dynamic force-time and force frequency characteristics of the Activator Adjusting Instrument and to validate its effectiveness as a mechanical impedance measurement device; in addition, to refine or optimize the force frequency characteristics of the Activator Adjusting Instrument to provide enhanced dynamic structural measurement reliability and accuracy. METHODS: An idealized test structure consisting of a rectangular steel beam with a static stiffness similar to that of the human thoracolumbar spine was used for validation of a method to determine the dynamic mechanical response of the spine. The Activator Adjusting Instrument equipped with a load cell and accelerometer...
Read MoreThe Healthiest Fruit Juices
Superior antioxidant activity” can be misleading because testing is usually done on a “limited spectrum” of antioxidant activities. Many nutritionists recommend that you eat whole fruit instead of the juice because the juice itself has so much sugar in it There’s a lot of talk these days about “antioxidants,” especially when it comes to juices and beverages. Have you seen different products being marketed as “super antioxidants?” Want to know which beverages have the “best” antioxidant power? Here’s the thing…claims of “superior antioxidant activity” can be misleading because testing is usually done on a “limited spectrum” of antioxidant activities. So researchers from UCLA did some hard core testing to figure out which juices have the best antioxidant power. They used 4 tests to determine antioxidant potency, which provides us with a much better analysis of the juices. Here are...
Read Morehow will you benefit most from chiropractic?
Spoiler: chiropractic isn’t just to be in no pain What if i told you a spinal tune up is a proactive choice for your life I’ve been getting great feedback from patients about the blog. But I must tell you that I have been a little discouraged lately because I didn’t really think they were making that much of a difference in your lives. Sure, it’s a good read and offers some great information, but is it really CHANGING anyone’s routine, anyone’s habits, anyone’s quality of life? I was beginning to think the answer was no…but then something happened. I had a patient come in who I hadn’t seen for quite a while. When I asked her how she was doing, she said she was fine. She told me she’d been reading the blog and had learned a ton...
