Exercise therapy for low back pain

20.04.2010
IRSST and Universite de Montreal study on treatment of common disability

Low back pain (or lumbago) is a common ailment often triggered by something as simple as lifting a suitcase. What is the best way to remedy the situation? An exercise machine designed specifically for back muscles could be the solution according to a new study published in the Journal of the American College of Sports Medicine.

"If you want to bring about physiological change to help the development and endurance of back muscles, you must focus your training on those specific muscles and not other muscular groups such as hip extensors," says Christian Larivière, a professor at the Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST), who conducted the study with Université de Montréal researchers Bertrand Arsenault, Rubens A. Da Silva, Sylvie Nadeau, André Plamondon et Roger Vadeboncoeur.

The investigation requested that subjects aged 18 to 65 – some healthy and others with low back pain – complete various exercises. Electromyography (EMG) sensors were used to measure the level of activity and fatigue in various muscles during the routine. "Thanks to this technique, we can target tired muscles which aren't yet showing a decrease in strength," says Larivière.

Test subjects also used a machine designed for back exercises in a semi-sitting position. Results clearly showed that using this machine was beneficial. Using a cushion to stabilize the pelvis brought about a better response from the back muscles. In addition, extending the legs strengthened muscles. "Therefore, we can decrease the use of hip muscles and in turn increase the use of the back muscles," says Larivière.

Such exercises can only help reduce pain and disabilities caused by back pain, says Larivière. He recommends those who suffer severe hurt begin with stretches on the ground with low to medium effort. "Progressively, the individual will gain confidence and can use machines that require superior strength," he says.

Larivière highlights the fact that six out of 10 Quebecers will suffer from back pain in their lifetime. "Musculoskeletal disorders are a serious public health issue," says Larivière. "They're also an economic problem. In 2007, back pain cost Quebec's Commission de la santé et de la sécurité du travail $516 million in worker compensations."

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
