Citius, Altius, Sanius Kick Off

Kick-Off Event

Papendal, The Netherlands

The 22nd of February 2018 marked the beginning of the Citius, Altius, Sanius project, one of the most ambitious projects from the Netherlands Organisation for Scientific Research (NWO).

Plux is proud to be a Portuguese company among such esteemed company that is being conducted by an alliance of eight universities and university medical centers and six universities of applied sciences who will collaborate on the project with NOC*NSF (Dutch Olympic Committee/Dutch Sports Federation), more than 20 businesses (including Royal Dutch Gazelle, Adidas and insurance company Zilveren Kruis), several sports associations, including those representing Football (KNVB), Hockey (KNHB), Baseball (KNBSB) and Tennis (KNLTB), sports teams (including Team Sunweb), sports physicians and sports physiotherapy practices.

We will be a part of two project within this project:

  • P4 - Fitness & Strength Training (optimizing training load, muscle stress)

This project focuses on fitness and strength training as one of the largest and most injury prone sports in the Netherlands. The challenge is to develop real-time feedback systems using musculoskeletal models, providing information on cardiovascular and muscle load that enables the athlete to optimize the training schedule and its intensity taking his or her power capability into account.

  • P7 - Coordination tennis & baseball (motor control, muscle coordination, local overload prevention)

This project aims at preventing the frequently occurring shoulder and elbow injuries in baseball and tennis players. The means to reach this aim include two developments: (1) The incorporation of individual musculoskeletal models in avatars that inform the athlete about the current load on shoulder and elbow followed by suggestions for behavioral adaptations to decrease this load, and (2) the creation of a smart racket and algorithms delivering information on the performance and the (risk for over)load of the shoulder and elbow of the player.

The user community of the program comprises a broad variety of stakeholders, including the national sports council NOC*NSF, sports federations like the KNAU, the KNBSB and the KNLTB, including their athletes and coaches, city councils, sports-medical associations, fitness companies, sports equipment companies and sensor and gaming companies. All of these stakeholders take a strong interest in the program and are keen on contributing to its success. This is reflected in their support letters and the in kind and in cash contributions they are willing to make. The sports councils are interested in increasing participation in their sports and in healthy ways of increasing performance in both recreational and elite athletes, and are committed to facilitate investigations and measurements in their respective domains. Cities with a strong health agenda support the program because it fits their policy to improve public health through sports and exercise; they will provide infrastructural support. Sports-medical associations are interested in improving athletic and public health and in developing relevant knowledge and applications to that end. They will bring in their expertise in their various expertise. The incentives of companies to participate include R&D, co-development of equipment, generate and sharing knowledge to support and improve their products. To this end, they will make their prototypes and existing products and expertise available to the program.

Citius, Altius, Sanius

Injuries prevention and performance improvement
in both amateur and top-level sport

Plux is proud to announce that as part of its endeavor to extend its line of products to the sports market, we were invited, and will be participating in a 6.2M€ research fund that will target injuries prevention and improve performance in both amateur and top-level sport.

We will be participating on the Citius, Altius, Sanius (Faster, Higher, Healthier), a Dutch research project. The research is being conducted by an alliance of eight universities and university medical centers and six universities of applied sciences who will collaborate on the project with NOC*NSF (Dutch Olympic Committee/Dutch Sports Federation), more than 20 businesses (including Royal Dutch Gazelle, Adidas and insurance company Zilveren Kruis), several sports associations, including those representing Football (KNVB), Hockey (KNHB), Baseball (KNBSB) and Tennis (KNLTB), sports teams (including Team Sunweb), sports physicians and sports physiotherapy practices.

Plux’s engineering contribution intends to develop methods and systems to facilitate the identification of injury risk factors related to load and coordination (together with KNLTB and KNBSB), by using, but not limited to, normative data, as well as modification of those factors in tennis and baseball by performing timing diagnosis analysis. The challenge is to then develop, a feedback system that provides information on the (accumulated) load and key coordination parameters, based on power flow models and ligament loading estimates. Based on this data, the feedback to the athlete should allow for rehabilitation at home with a graded return to sport.
We will also be contributing to the project with our products, physioplux EXPERT, our equipment geared towards EMG analysis of key timing indicators for asymptomatic versus symptomatic side comparison and physioplux GO equipment’s or mobile platform for EMG training and assessment.
With such a heterogeneous consortium, we believe that the potential for success is huge, due to its engrained roots, both on the market, the athlete’s and the researchers ecosystem.

fNIRs Press Release

Miniaturized fNIRS sensor

PLUX and Charles River Analytics launch a new miniaturized fNIRS sensor
High-quality signal and available at a fraction of current systems costs

Lisbon, Portugal; Boston, Massachusetts

Biomedical engineering company PLUX and R&D company Charles River Analytics announced the joint commercial launch of a new miniaturized wireless fNIRS sensor that captures high-quality signal at a fraction of the current systems costs.

Functional Near-Infrared Spectroscopy (fNIRS) sensors measure the red and infrared light reflectance in the cortical tissue. These sensors are typically applied on the forehead and can be used to estimate blood oxygen saturation level in the brain tissue.

The new fNIRS sensor was developed under a US Army project called “A system for augmenting training by Monitoring, Extracting, and Decoding Indicators of Cognitive Workload” (MEDIC)*, and a US Air Force contract called an “Adaptive toolkit for the Assessment and augmentation of Performance by Teams in Real time (ADAPTER)”. The sensor is being used as part of an unobtrusive set of biosignals sensors and advanced data processing software to automatically sense indicators of cognitive workload to augment performance observations, offering insight into factors underlying that performance.

Dr. Bethany Bracken, project lead researcher, stated that such an unobtrusive system to measure cognitive state will be useful across multiple domains including to make laboratory-based experiments easier and portable into real-world environments, to assess training and teaching curriculum effectiveness and tailor training curriculum to the needs of each student, and during testing and evaluation of new tools early in the design phase to streamline development of intuitive tools.

PLUX Chairman, Prof. Hugo Gamboa states that this collaboration exemplifies how PLUX deep engineering capabilities and expertise with Biosignals support the design of innovative sensor solutions for various fields of use.

Both companies confirm that they are developing an even more robust and integrated sensor solution, together with additional support software, and are expecting to patent and introduce this innovation to the market in 2018.

The current sensor is marketed for the research community under PLUX biosignalsplux product line and is available for purchase either on PLUX online store or through its resellers network.

Note: The development of this sensor is based upon work supported by the United States Army Medical Research and Materiel Command under Contract No. W81XWH-14-C-0018 and United States Air Force under Contract No. FA8650-14-C-6579.
