Dynamic chest compression occurs during spinal manipulation. While dynamic chest compression has been well studied in events such as motor vehicle collisions, chest compression forces have not been studied during chiropractic manipulation.
In a study published online today in the Journal of Manipulative and Physiological Therapeutics, researchers quantified and analyzed the magnitude of chest compressions during typical as well as maximum chiropractic manipulation and have found them to be well under the threshold for injury.
"Results from this preliminary study showed that maximum chest compression during chiropractic manipulation of the thoracic spine is unlikely to result in injury," according to lead investigator Brian D. Stemper, PhD, Associate Professor, Department of Neurosurgery, Medical College of Wisconsin, Milwaukee, WI. "We performed this study to get a better understanding of the force limits of chiropractic manipulation. This information may lead to safer manipulation procedures and help to decrease the possibility of adverse patient outcomes."
In the first part of the study Professor Stemper and his co-investigators worked with two practicing doctors of chiropractic, each with a minimum of 4 years of doctoral training and at least 7 years of healthcare experience. Using a crash test dummy they measured the level of chest compression induced during "normal" chiropractic manipulation and during spinal manipulations wherein the doctors of chiropractic exerted maximum effort. They performed simulated chiropractic manipulations on the test dummy at the midback level (T7 to T8 vertebrae).
In the second part of the study, an instrumented mechanical device was used to apply and measure the forces necessary to induce chest compression in the test dummy. These forces were increased until injurious levels of force were reached. The likelihood of injury was assessed and classified using the Abbreviated Injury Scale (AIS), which is a useful classification system that has been correlated to injury thresholds during biomechanical experimentation.
In the present study, manipulations incorporating typical and maximum efforts by the doctors of chiropractic resulted in maximum chest compressions corresponding to minimal risk of AIS 1 level injuries.
As with all types of patient care, Professor Stemper cautions that "individual patient characteristics including age, degeneration, and gender" should be taken into consideration during treatment such as chiropractic manipulation.

Hallman, PhD, and Boyd M. Peterson, DC.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
