Contact Us Activator Methods will respond to your request. The only instrument adjusting technique backed by 26 clinical trials The Activator Method is one of the most widely researched chiropractic techniques and the only instrument adjusting technique with 26 clinical trials to support its efficacy.
The relationship between pelvic torsion and anatomical leg length inequality: a review of the literature. Gemmel H, Allen A. Clin Chiropr. Immediate effect of activator trigger point therapy and myofascial band therapy on non-specific neck pain in patients with upper trapezius trigger points compared to sham ultrasound: A randomised controlled trial.
Blikstad A, Gemmell H. Variability of force magnitude and force duration in manual and instrument-based manipulation techniques. J Manipulative Physiol Ther. Of the 55 articles, 13 were eliminated from the final study. Of the 42 remaining articles, 6 were rated as class 1 evidence; 11 were rated as class 2 evidence and 25 were rated as class 3 evidence. In this article — the second in a series of two — we review the results of uses and usage, safety and educational requirements.
Of the 30 articles designated under the category of usage, 3 were rated as Class 1 evidence; 9 studies were classified as Class 2 evidence and 18 were rated as Class 3 evidence.
Overall the committee reached consensus that in clinical practice, there is broad application of these procedures. A minority report was written arguing that the reviewer was unable to reach a conclusion about the use of the Activator Instrument other than it is used as a clinical and research tool.
Of the 16 studies that dealt either explicitly or implicitly with safety, 4 were Class 1 evidence; 3 were Class 2 evidence and 9 were Class 3 evidence. Overall the committee reached consensus that the evidence supports that the Activator instrument is safe and has no more relative risk than do manual HVLA procedures. A minority report was written arguing that there is no evidence either to support or refute the view that MAD is safe.
Of the 5 studies that dealt with educational requirements, all were Class 3 evidence. Overall the committee reached consensus that there was no evidence in the literature with respect to educational requirements to form any conclusions. A minority report was written offering opinion that there is evidence with respect to educational requirements. J Can Chiropr Assoc. To use a previously validated dynamic mechanical impedance procedure to quantify changes in PA dynamic spinal stiffness at rest and during lumbar isotonic extension tasks in patients with low back pain LBP.
Thirteen patients with LBP underwent a dynamic spinal stiffness assessment in the prone-resting position and again during lumbar extensor efforts. Stiffness assessments were obtained using a handheld impulsive mechanical device equipped with an impedance head load cell and accelerometer.
Apparent mass measurements for the resting and active lumbar isotonic task trials of each patient were compared using a 2-tailed, paired t test. A significant increase in the PA dynamic spinal stiffness was noted for thrusts over the SP apparent mass [ These findings add support to the significance of the trunk musculature and spinal posture in providing increased spinal stability.
The committee evaluated the literature on the efficacy, safety, and uses of moving stylus instruments within chiropractic practice, and the educational requirements for chiropractic practice. Following the rating criteria for the evaluation of evidence, as outlined in the Clinical Guidelines for Chiropractic Practice in Canada , the committee reviewed 55 articles — all of which pertained to the Activator: Of the 55 articles, 13 were eliminated from the final study.
Of the 21 articles related to efficacy, five were identified as Class 1 evidence; 4 were identified as Class 2 evidence; and 12 were identified as Class 3. Overall, the committee reached consensus that the MAD procedures using the Activator were as effective as manual HVLA procedures in producing clinical benefit and biological change.
Free PMC Article. Abstract OBJECTIVE: To simultaneously quantify vertebral motions and neuromuscular and spinal nerve root responses to mechanical force, manually assisted, short-lever spinal manipulative thrusts.
Four patients underwent lumbar laminarthrectomy to decompress the central spinal canal and neuroforamina, as clinically indicated. Prior to decompression, finely threaded, 1. Following decompression, 4 needle electromyographic nEMG electrodes were inserted into the multifidus musculature adjacent to the pin mount bilaterally, and 2 bipolar platinum electrodes were cradled around the left and right S1 spinal nerve roots.
Spinal manipulative thrusts resulted in positive electromyographic EMG and compound action potential CAP responses that were typically characterized by a single voltage potential change lasting several milliseconds in duration. The temporal relationship between the initiation of the mechanical thrust and the neurophysiologic response to internal and external spinal manipulative therapy SMT thrusts ranged from 2.
Neurophysiologic responses varied substantially between patients. Vertebral motions and resulting spinal nerve root and neuromuscular reflex responses appear to be temporally related to the applied force during SMT. These findings suggest that intersegmental motions produced by spinal manipulation may play a prominent role in eliciting physiologic responses. Abstract OBJECTIVE: To quantify in vivo spinal motions and coupling patterns occurring in human subjects in response to mechanical force, manually assisted, short-lever spinal manipulative thrusts SMTs applied to varying vertebral contact points and utilizing various excursion force settings.
Triaxial accelerometers were attached to intraosseous pins rigidly fixed to the L1, L3, or L4 lumbar spinous process of 4 patients 2 male, 2 female undergoing lumbar decompressive surgery.
