MR Ergometer Dorsal Ankle Flexion

This MR Ergometer has been meticulously engineered to cater to the exacting requirements of medical professionals engaged in the spectral analysis of tibialis anterior, specifically targeting the m. Soleus, and the m. Gastrocnemius. This precision in muscle group targeting is crucial for clinical and research applications, allowing practitioners to delve deeper into the nuances of muscle function and performance.

A standout feature of this MR Ergometer is its MR conditional design, ensuring seamless integration within the magnetic resonance (MR) environment. This compliance is vital, as it guarantees the safety and compatibility required for accurate and artifact-free imaging and spectroscopy. This ergometer’s MR conditional status underscores its suitability for deployment in the demanding clinical and research settings that rely on the benefits of MRI technology.

Moreover, the ergometer’s workload adjustability of up to 100 watts offers a wide range of resistance levels, enabling tailored exercise protocols for patients. This adaptability is especially valuable when working with diverse patient populations or conducting research that requires controlled variations in exercise intensity.

Advanced Insights into Muscle Health: Muscle Spectroscopy

Muscle spectroscopy, also known as magnetic resonance spectroscopy (MRS), is a cutting-edge non-invasive imaging technique that delves deep into the biochemical composition of muscles. While traditional MRI provides structural information about tissues, MRS takes it a step further by exploring the chemical and metabolic aspects.

Key Applications

  1. Metabolite Analysis: MRS detects and quantifies various metabolites within muscle tissue, including creatine, phosphocreatine, ATP (adenosine tri-phosphate), and lactate. These compounds play pivotal roles in the muscle’s energy system.
  2. Metabolic Disorders: By studying metabolic changes in muscles, MRS offers valuable insights into conditions like metabolic myopathies, muscular dystrophies, type 2 diabetes, and sarcopenia.

Clinical Impact

  • Neurology and Internal Medicine: MRS finds applications in diagnosing and monitoring muscle health in patients.
  • Sports Medicine and Research: Athletes benefit from MRS to understand their muscle energy systems and fiber composition. This knowledge informs training strategies and enhances performance.

Precision with MR Ergometers

MRS conveniently leverages MR Ergometers for controlled activity assessments. The Lode MR ergometer ensures accuracy and reproducibility in tests, making it an indispensable tool for muscle research and clinical practice.

Why the MR Ergometer Ankle Dorsal Flexion?

High standards

Lode is a socially and environmentally responsible company. All Lode products are RoHS/WEE compliant and Lode is ISO 9001:2015, and ISO 13485:2016 certified. All medical products comply to MDD 93/42/EEC, incl. IEC 60601-1.

Tesla independent

The choice of materials and the special design makes that the Lode MRI ergometer is useable for various Tesla MRIs without giving artifacts on the imaging.

Exercise instead of medicine

When a test subject is able to do exercise, it is always recommended above pharmacologic stress. It allows objective measurement in either level of cardiac conditioning and/or level of cardiac work. It is safe and perfectly reproducible.

Unique ergometer for MRI

With this unique ergometer it is possible to perform an exercise test in an MRI. An ergometer on the tabletop of an MRI ensures minimal time stress induction and imaging without coursing artifacts on the imaging.

Designed for use with MRIs at 1.5 and 3 Tesla

The ergometer can be used with various types of MRI scanners from renowned brands, like:

  • Philips
  • Siemens
  • GE

Product features

Suitable for Siemens MRI scanners

The MRI Ergometer can be used in combination with many Siemens Magnetom MRI scanners, like Skyra, Aera, Verio, Essenza, Prisma, Avanto Fit, Vida, Sola, Altea, Lumina and Spectra.

Low noise

Due to accurate manufacturing and the careful choice of materials the product has an extremely low noise level.

Small adjustment steps

The workload of the Lode ergometers is adjustable in steps of only 1 watt. Depending on your wishes, the test operator or the test subject can adjust the workload. The steps of 1 watt are possible in the manual mode as well as within protocols.

Up till 3 Tesla

Lode MR ergometers are MR conditional. This means that under certain conditions, the ergometer can be used safely with MR ergometers up till 3 Tesla without artifacts being visible on the image.

Suitable for Philips MRI scanners

The ergometer can be used with with various Philips MRI devices like Philips Achieva and Ingenia.

Suitable for GE MRI scanners

The Lode MR Ergometer can be used with GE Signa and Discovery scanners.

Accurate over a long period of time

The Lode ergometers are supplied with an electro-magnetic braking mechanism of Lanooy (eddy current). The biggest advantage of this braking system compared to a friction braking system is the absolute accuracy and the accuracy over time. Moreover, friction braking systems have more wearing parts.

Service friendly ergometer

Lode ergometers are very service friendly. In general, total costs for spare parts are so low that they are negligible. Furthermore, most options are so easy to install and firmware is so easy to update that labor costs are minimal. Moreover, the ergometer can be cleaned easily.

Understanding MR Ergometry: A fusion of medical imaging and physical activity

Medical imaging plays a crucial role in modern healthcare, employing various techniques to delve into the inner workings of the human body, aiding doctors in understanding and treating illnesses. Some health issues are not visible externally, necessitating the use of advanced technologies. The evolution of X-rays, magnetic resonance imaging, and ultrasound has significantly enhanced medical imaging, reshaping the landscape of healthcare.

Over time, healthcare professionals and researchers have strived to comprehend how the human body functions in different states, such as health, illness, rest, and exercise. They aim to study the body’s responses during and after physical activity. Regular medical images offer only glimpses and don’t capture the full range of bodily functions. Certain health problems or irregularities, like some heart issues, become apparent only during activity. Therefore, it is crucial to assess performance limits and adopt a dynamic approach to identify these irregularities.

Magnetic resonance imaging (MRI) has been a global presence in hospitals since the early 1980s. The combination of exercise and imaging brings numerous advantages, extending beyond the study of the heart and muscles to various other medical applications.

For over two decades, Lode has been a pioneering force in developing ergometers compatible with MRIs. Widely used in hospitals worldwide, these ergometers offer valuable insights into the intricate relationship between exercise and imaging.

Frequently asked questions

Is it possible to use the MRI ergometer with all brands of MRI scanners?

The MRI ergometer is designed to be used with Siemens, GE and Philips MRI scanners. The type of movement (up-down, push-pull or circular) is depending on the diameter of the scanner and the kind of research (cardiac, spectroscopy etc)

Can Lode MR ergometers be used in combination with MRI scanners of 3 Tesla

Yes, since January 2010 all Lode MRI ergometers are designed to be used MRI scanners up to 3 Tesla

Is Lode recommending special disinfection procedures for the Lode products due to COVID-19?

Yes, Due to the fact that the scientific research on the spread of Covid-19 is not yet conclusive Lode recommends to disinfect and clean all Lode products and their accessories (cuffs, heart rate belts, SpO2 sensors, handgrips/rails, touchscreens etc) that are in contact with the patient and or the medical personnel with a standard disinfectant as used in the hospital before and after every patient, with attention and care!

Since these agents are sometimes aggressive it might be advisable to check the effect on sensitive surfaces, like cushioning on non-visible areas. Lode will not take responsibility for discoloration due to these agents.

Is the Lode MR ergometer MR safe and / or MR conditional?

Lode MR ergometers are MR conditional. This means that the ergometer can be used safely in the MR room under certain conditions without artifacts being visible on the image. The minimum distance to the bore is the determining factor here.
