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: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
