Computer Simulations and Use of Force Investigations

Category: Press Article Publication: Force Science Institute “Editor’s Note: When officers lawfully respond to deadly threats, their money, reputation, and freedom still hinge on whether society believes their version of events.  Dr. Geoffrey Desmoulin, a Certified Force Science Analyst and Principal of GTD Scientific Inc., developed an impressive testing and shooting reconstruction methodology to scientifically evaluate use of […]

Free Axial Vibrations At 0 to 200 Hz Positively Affect Extracellular Matrix Messenger Ribonucleic Acid Expression in Bovine Nucleus Pulposi

Category: Publication Authors: Geoffrey T Desmoulin, Carol R Reno, Christopher J Hunter Publication: Spine, Volume 35, Issue 15, Pages 1437-1444 Study Design. Bovine caudal intervertebral discs (IVDs) were exposed to free axial vibration for 10 to 60 minutes at 0 to 0.5g and 0 to 200 Hz. Expression of messenger ribonucleic acid for aggrecan, collagen […]

Is Vibration Truly an Injurious Stimulus in the Human Spine?

Category: Publication Authors: Taryn E Hill, Geoffrey T Desmoulin, Christopher J Hunter Publication: Journal of Biomechanics, Volume 42, Issue 16, Pages 2631-2635 Epidemiological data at one time was taken to suggest that chronic vibrations—for example operating vehicles with low-quality seats—contributed to intervertebral disc degeneration and lower back pain. More recent discussions, based in part upon […]

Blast-Induced Neurotrauma: Surrogate Use, Loading Mechanisms, and Cellular Responses

Category: Publication Authors: Geoffrey T Desmoulin, Jean-Philippe Dionne Publication: Journal of Trauma and Acute Care Surgery, Volume 67, Issue 5, Pages 1113-1122 Background: With the onset of improved protective equipment against fragmentation, blast-induced neurotrauma has emerged as the “signature wound” of the current conflicts in the Middle East. Current research has focused on this phenomenon; […]

A Technique for Conditioning and Calibrating Force-Sensing Resistors for Repeatable and Reliable Measurement of Compressive Force

Category: Publication Authors: Rick S Hall, Geoffrey T Desmoulin, Theodore E Milner Publication: Journal of Biomechanics, Volume 41, Issue 16, Pages 3492-3495 Miniature sensors that could measure forces applied by the fingers and hand without interfering with manual dexterity or range of motion would have considerable practical value in ergonomics and rehabilitation. In this study, […]

Selective Control of Leg Muscle Activation Patterns and Ankle Forces Using a Multi-Chambered Stimulation Cuff Implanted on the Sciatic Nerve

Category: Publication Authors: G Desmoulin, Joaquín Andrés Hoffer Publication: IFESS 11th Ann. Conf., Phila A 20-mm Neurocuff(™) with 8 sets of tripolar electrodes placed inside longitudinal chambers separated by insulating ridges (Hoffer et al., 1998) was implanted on the left sciatic nerve of 3 cats. Epimysial bipolar EMG electrodes were sutured onto 8 calf muscles. […]

Spinal Mechanisms of Pain Control

Category: Publication Authors: Geoffrey T Desmoulin, Nasif I Yasin, Darryl W Chen Publication: The Clinical Journal Of Pain, Volume 23, Issue 7, Pages 576-585 Objectives: To demonstrate initial results using Khan Kinetic Treatment (KKT) as a chronic neck pain treatment and to present pain control mechanistic theory on which the treatment is based. Methods: A […]

Lumbar Mechanics From Ultrasound Imaging

Category: Publication Authors: Geoffrey Desmoulin, Theodore Milner Publication: Canadian Acoustics, Volume 35, Issue 2, Pages 61-68School of Kinesiology-Simon Fraser University The feasibility of estimating lumbar mechanics in-vivo was evaluated using ultrasound imaging. Images were obtained while subjects were seated, with the pelvis fixed, and pulled on an anchored cable by isometrically contracting trunk muscles at […]

Initial Results Using Khan Kinetic Treatment™ as a Low Back Pain Treatment Option

Category: Publication Authors: Geoffrey T Desmoulin, Nasif I Yasin, Darryl W Chen Publication: Journal of Musculoskeletal Pain, Volume 15, Issue 3, Pages 91-102 Objectives: Demonstrate initial results using Khan Kinetic Treatment [KKT™] as a low back pain [LBP] treatment option. Methods: A self-reported functional assessment, LBP questionnaire, and pain medication dose were used as the outcome measures […]
