Accutrack® by SIGVARIS GROUP: A reliable sensor for measuring compliance with compression therapy
SIGVARIS GROUP has developed the Accutrack® sensor to accurately monitor the wear of close-fitting textile items such as compression devices.
Non-compliance: A common pain point for medical compression
Medical compression is an essential treatment for venous and lymphatic diseases (1,2). Like any treatment, its effectiveness depends on proper adherence (3). However, compliance is often poor in the field of medical compression. Studies report non-compliance in about one to two-thirds of patients (4-7), with only 21% of patients claiming to wear their compression daily (6). Various reasons explain this low adherence, among the main ones: discomfort (itching, irritation, sweating) and fitting difficulties (5,7-10).
Accutrack®: A new device for objective measurement of compliance
The Accutrack® system consists of:
• a sensor,
• an RFID (Radio Frequency Identification) reader,
• a programming and a visualization software.
The Accutrack® sensor incorporates an accelerometer that records a motion signal every minute to provide a wear or non-wear status of the compression textile in 15-minute increments.
What are the advantages of the device?
- The data collection is accurate (11)
- The device is easy to use (12)
- The sensor is discreet (12)
- The sensor is machine washable at 40°C and 800rpm (13)

Demonstrated reliability in real conditions of use
The reliability of the Accutrack® sensor for monitoring the use of medical compression socks was evaluated in the VALITRACK study (12). The sensor's performance in correctly identifying the wear status experienced by patients was measured by calculating sensitivity and specificity.
Under real usage conditions, the sensitivity of the Accutrack® sensor is excellent, with a 98.6% probability of accurately reporting wear, and its specificity is also high, with a 95.2% probability of correctly reporting non-wear.
Beyond its current use in enhancing the robustness of clinical trials outcomes, the Accutrack® sensor could become a valuable tool in routine practice. For example, it could help boost patient motivation by demonstrating a correlation between wearing compression garments and a reduction in symptoms and certain clinical signs.
How to order the device?
How to maintain the Accutrack® sensor?
The maintenance of the Accutrack® sensor is done with warm soapy water if needed.
Is the Accutrack® sensor waterproof?
Yes, the Accutrack® sensor is waterproof and can withstand machine washing (13).
How to order the Accutrack® device?

- An expert will contact you within about ten days to assess your needs and provide you with a suitable offer.
How to use the Accutrack® system?
1 - Use the software to program the sensor
- Install the software by following the instructions.
- Plug the RFID reader into a USB port on your computer.
- Open the "Accutrack.exe" software previously installed.
- Place an Accutrack sensor on the RFID reader.
- Program the sensor according to your needs.
2 - Use the sensor to collect data related to usage time
Attach the Accutrack® sensor to the textile product following the instructions in the manual.
3 - Use the software to view and export data
- Plug the RFID reader into a USB port on your computer.
- Open the "Accutrack.exe" software.
- Place an Accutrack sensor on the RFID reader.
- Once the data are downloaded, click on the "Graphic visualization" or "Data exportation" buttons to view or archive your records.
Is the Accutrack® software compatible with macOS and Windows?
The Accutrack® software is compatible with Windows and will soon be available for macOS.
Does the skin come into contact with the sensor?
The Accutrack® sensor is not in direct contact with the skin. Only the stainless steel tip (material complying with ASTM F899 - Standard Specification for Wrought Stainless Steels for Surgical Instruments) that allows the sensor to be clipped onto the fabric is in direct contact with the skin.
Is there a minimum order quantity for Accutrack® sensors?
The minimum quantity is one box containing two sensors.
Does the Accutrack® device have CE marking?
Yes, the Accutrack® device has CE marking. This product is an electronic device that complies with current European directives. This product is not a medical device. This marking represents SIGVARIS GROUP's commitment to the conformity of the device.
