Lode ergometers with Pedal Force Measurement come standard with the Lode Ergometry Manager - Pedal Force Measurement software module. The combination of software and ergometer results in a unique application for sport-medical stress testing, rehabilitation and research.
The Pedal Force Measurement module adds the following features to the Lode Ergometry Manager:
- Continuous registration of the forces exerted on the left and right crank;
- Specific Pedal Force Measurement visualisations;
- Specific Pedal Force Measurement reports and analysis: numeric data such as peak values, averages, absolute maximum, angle, total efficiency, rpm and left/right ratio are registered and saved. Export to statistical programs is possible with the optional LEM Expansion Module Export;
- Protocols for pedal force measurement can be programmed based on time intervals (with a maximum of 60 minutes), enabling a continuous registration of the pedal force;
- On-line visualizations of the forces and Torque on the left and/or right crank during the test;
The software offers the possibility to define “area’s of interest” (AOI) and to analyze these separately.
The standard crank is not intended for regular pedal exchange. If you intend to change pedals regularly, we advise to order the adjustable sports cranks with hardened steel pedal mounting block (part number 925808).

Patients that have to learn how to walk again can be anxious. The Lode BWSS offers various tools to take away this anxiety. Of course, safety is one of the most important aspects that Lode takes into consideration. That is why a fall- stop comes standard with this system. In case a patient impends to fall, the fall- stop will make sure that the patient will remain in the system and will not be injured.
Many patients that have to learn how to walk again are mobile through a wheelchair. The Lode BWSS takes exactly these patients into full consideration: with the optional entrance plate the patient can be placed on the treadmill in the wheelchair. The harness can easily be put on to the sitting patient. Then the patient can stand up directly from the wheelchair with support of the Lode BWSS thanks to the lifing function. This function is suitable for patients up to 160 kg. Now the patient can start the therapy without much effort.

connecting Lode products has never been easier! Lode rehab and sports products have a standard Network card:
- To be able to connect the first product to the PC with L(C)RM a Lode proprietary network to PC cable is needed (#930930). This cable is standard included with Lode Rehab Software.
- From the second product onward products can be connected to the previous one, creating a bus network configuration;
- The last product always needs a termination plug to avoid interference and loss of data. Therefore all products with such a network card come with a termination plug.
Benefits
- Lossless data connection
- High bandwidth
- No interference of COM ports
- Daisy chain connection
- Full access of all data in the product to LCRM
During the test, various ergometry data can be visualized graphically and/or numerically. The Lode Ergometry Manager offers various standard visualizations: workload, rpm, velocity, slope, SPO2, accumulated energy, heart rate*, SpO2* blood pressure*, distance, borgscale, METs, W/kg and time. In combination with some expansion modules, even forces exerted on the cranks, or an estimation of the maximum oxygen uptake can be visualized. With the click of a button the workload can be adjusted and the blood pressure measurement can be started.
Monitoring the test
The operator can specify which parameters should be shown during the test. The data is stored within the Lode Ergometry Manager database. All views on the monitor can be saved for different applications. Data not visualized during the test is recorded and can be analyzed at any time.
Even after an ergometry test has been completed, the Lode Ergometry Manager will help the operator to efficiently finalize the work. Test data can be seen at any time after the test. The Lode Ergometry Manager will help analyzing the results and print reports. In a clear overview you will find all tests that have been executed by a test subject. Analysis views can be saved for different applications. It is possible to take a closer look at a test afterwards, by zooming into a specific part of the test’s graphic and synchronize these graphs with a link
Analyzing the test
When analyzing the results, different tests from a single test subject can be compared with each other and the operator can define which ergometry data they would like to evaluate. It is also possible to compare just a part of the test. This helps to monitor the progress of the subject. Test subjects can be assigned to a group.
Different test subjects can be compared against each other in a graph. The results of a group can be analyzed with this feature. There are specific visualizations for the PWC analysis. The METs are calculated for arm ergometry, bicycle and treadmill ergometry. The results can be visualized in graphs and in the test results tables
Printing
It is possible to print out all possible visualizations and reports after the test in PDF format. The report lists the logo of the institute the name of the test subject, the test protocol, date and time.
In order to quickly and efficiently execute an ergometry test, tests can be prepared in advance. The test subject data, exercise protocols and devices can be pre-selected.
Test protocols
There are some standard test protocols preprogrammed in the software. Furthermore, it is possible to create an infinite number of protocols. Programmable stages are: Heart rate controlled, Step, Ramp, Linear, and Recovery. Protocols can be copied and edited. The interval time for blood pressure measurement and a heart rate limit can be preset. Protocols can be made easily in a few steps with protocol templates
Also body weight controlled and protocols based on METs values can be programmed. Targets for energy, heart rate and distance can be defined. The PWC protocol can be customized and the WHO protocol is standard implemented.
Safety
For safety reasons alarms can be preset for maximum heart rate, maximum blood pressure and drops in heart rate, rpm and in blood pressure for each test subject. Test subjects with an alarm can be automatically moved to the recovery step.
The Lode MRI ergometers are designed to produce physical stress within an MRI device. The MRI ergometer can be used for cardiac examinations, cardiac research, spectroscopy and other examinations and research.
For cardiac MRI examinations, the MRI ergometer can be produced with a pedal (circular) or push/pull exercise movement.
For spectroscopy MR examinations there is an ergometer available with up/down movement for the upper leg and an ankle MRI ergometer for the calf muscles.
The MRI ergometers are compatible for the most types of MRI scanners of Siemens, Philips and GE. The choice of materials and the special design makes that the Lode MRI ergometer can be used for 1,5 and a 3 Tesla MRI without giving artifacts on the imaging.
Our MRI ergometer with its low start-up load enables exercise. When a test subject is able to do exercise, this is always recommended above pharmacologic stress. It allows objective measurement of improvement in either level of cardiac conditioning and/or level of cardiac work. It is safe and what is very important is perfectly reproducible.
A USB A-B cable for service purposes and connection to ECG and pulmonary testing devices is standard delivered with the product.To connect older equipment with RS232 or other connectors you need a special interface cable that can be ordered separately.

Often, the lack of systemic arterial hypertension and the lack of a resting arm-leg blood pressure gradient are used to assess the adequacy of the anatomic result after intervention for coarctation of the aorta (CoA). Some patients with no arm-leg gradient at rest may develop a gradient with exercise, leading caregivers to question the success of the repair. It is not clear what the prevalence is of patients who have undergone a successful intervention for CoA and have no arm-leg gradient at rest but develop a significant gradient with exercise and which factors may predict the development of an arm-leg gradient with exercise. This study evaluates the prevalence and predictors of an exercise-induced arm-leg gradient in subjects who have undergone an apparently successful intervention for CoA.
