Seismic for the spine: Vibration technology offers alternative to MRI

11.03.2016

Magnetic resonance image isn't everything. A new University of Alberta study shows that vibrating the spine may reveal more when it comes to treating back pain. Teaming with the University of South Denmark to study the lumbar spine of twins, Greg Kawchuk and his team demonstrate that structural changes within the spine alter its vibration response significantly.

Instead of using large seismic vibrations to find oil, we used gentle vibrations to find out where problems exist in the back," explains Kawchuk, professor of physical therapy at the U of A's Faculty of Rehabilitation Medicine. "By studying and testing vibration responses in identical twins, we were able to demonstrate that structural changes within the spine alter its vibration response."

Publishing online in Scientific Reports on March 11, 2016, the identical twin study design is significant and unique for biomechanical studies like this one. In the instance where twins had similar spines, the vibration responses were statistically similar. Alternatively, if one twin had a different spine, due to an accident or injury for example, the vibration responses were significantly different from each other.

"In Denmark we have the world's largest and most comprehensive twin registry and using this unique resource, we have been able to contribute to research that can potentially help to diagnose millions of back pain patients," says Jan Hartvigsen, professor of clinical biomechanics and musculoskeletal research, University of South Denmark.

The findings show the viability of vibration as a diagnostic tool that could help improve MRI utilization in the short term, Kawchuk says.

"One of the biggest problems in back pain today is over utilization of MRI scans in patients that do not need them. This is a waste of health care resources that leads to over treatment and even increased disability. By using a simple, safe and inexpensive technology like this, we can potentially decrease the use of these scans significantly," says Hartvigsen.

The study also has implications in the long term and could provide new diagnoses not seen by current imaging tests.

"While an MRI shows us a picture of the spine, it doesn't show how the spine is working. It's like taking a picture of a car to see if the car is capable of starting. Vibration diagnostics shows us more than how the spine looks, it shows us how the spine is functioning," explains Kawchuk.

"Back problems are a significant cause of disability world-wide. For 90 per cent of these patients, current diagnostic methods are not able to identify their problems," says Cameron Schuler, President and CEO, VibeDxTM, who co-founded the VibeDx Diagnostic Corp, a TEC Edmonton spinoff company that has licensed the technology developed by Kawchuk. "Our hope is VibeDx™ will help improve our ability to identify the cause of the patient's back problem, which will then assist clinicians in matching a patient to the best course of treatment for their specific situation."

"VibeDx™ is a TEC Edmonton client and we're delighted to see international recognition for this innovative University of Alberta spinoff," said Chris Lumb, CEO of TEC Edmonton, an accelerator for early stage technology companies. "VibeDx™ is a prime example of the outstanding research and commercialization taking place in Edmonton and at the University of Alberta."

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Im Focus: Determining the Earth’s gravity field more accurately than ever before

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...

Im Focus: Tube anemone has the largest animal mitochondrial genome ever sequenced

Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.

The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....

Im Focus: Tiny light box opens new doors into the nanoworld

Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.

Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...

Im Focus: Cost-effective and individualized advanced electronic packaging in small batches now available

Fraunhofer IZM is joining the EUROPRACTICE IC Service platform. Together, the partners are making fan-out wafer level packaging (FOWLP) for electronic devices available and affordable even in small batches – and thus of interest to research institutes, universities, and SMEs. Costs can be significantly reduced by up to ten customers implementing individual fan-out wafer level packaging for their ICs or other components on a multi-project wafer. The target group includes any organization that does not produce in large quantities, but requires prototypes.

Research always means trying things out and daring to do new things. Research institutes, universities, and SMEs do not produce in large batches, but rather...
