[February 18, 2009] Painvision Symposium

Dear reader,

Painvision Symposium

On February 13th, 2009 Painvision organized their first Symposium titled “Pijnopvolging bij dementerende bejaarden vanuit de praktijk”. The symposium was held in Living and Care Centre De Wingerd (Leuven) and was a succes! More than 110 participants enjoyed the presentations and provided usefull feedback during the reception afterwards! More info about the symosium, presentations and also some nice pictures of the speakers and reception afterwards are available on our website by just clicking here.

Why did Painvision postpone the user commission of 28 October?

The tetra project was already running for 2 years at the end of September 2008. Although the past 2 years were fruitful as you all could experience during the users commissions, our work can always be improved towards future investors. As a research consortium we keep a tight budget leaving enough means to continue the tetra project till the end of February 2009 and conclude our research objectives. In this regard, approval by the IWT was sought and the project is extended for 5 months. During this additional period we make further scientific progress completing the research goals of the project in order to offer investors an even better outcome.

  • vzw ‘Rusthuizen Zusters van Berlaar’ Wiekevorst

    In response to the question of the ethical committee of the ‘VZW Rusthuizen Zusters van Berlaar’, about ‘an adequate pain assessment instrument for elderly in a geriatric centre’, a presentation was given on Friday 26th of September 2008. The Painvision project was presented, focusing on the current evolution of pain assessment instruments. The members of the committee were enthusiastic, and they look forward to future commercial products of this project.

  • KHK-info-avonden ‘Start to study’ Lier

    ‘Start to study’ is one of many evenings which the association K.U.Leuven sets up for high school students and their parents, to choose a suitable bachelor or master degree. On the 9th of October 2008 at ‘start to study’ in Lier, among other things, the topic ‘High-tec in nursing: can you measure pain with a camera?’ was chosen. The added value of the cooperation between engineers and nurses in the project was highlighted. Although the audience wasn’t familiar with this topic, they realised the innovative approach of pain measurement, and showed their interest.

  • Smart Care Unlimited Event Eindhoven

    The province Noord Brabant in the Netherlands takes part with their ‘Smart Care’ program, to the ‘Dutch Design Week’ (a design event in the Netherlands). With this program they want to integrate and improve ICT in care for the elderly and chronically ill people. We were invited on the 22th of October 2008 to the ‘Smart Care Unlimited Event’ in Eindhoven, to present the Painvision project by means of our dvd. Visitors as well as organizers were enthusiastic, and look forward to future products.

Dear reader,

In April 2008, our project was placed in the spotlights by " Bio-ingenieus" (a periodical of the K.U.Leuven faculty Bioscience Engineering). This article presents the Painvision project to the K.U.Leuven Bio-engineers. This article also attracted the attention of the "Campuskrant" which is the major university newspaper, with a scope way beyond the university. Pieter Schiepers (K.U.Leuven) and Bert Bonroy (K.H.Kempen) ware interviewed by a Campuskrant journalist which resulted in a cover article published on May 14th, 2008. Afterwards the Belgian press agency Belga captured this article and broadcasted an abstract of this interview all over the whole world. This press communication appeared in a lot of internet sites as well as different newspapers. We tried to list them up and provides an overview below:


[January 18, 2008]

Dear reader,

First of all we would like to wish you a happy new year and the very best for a successful 2008!

The main item of this January edition is the introduction of the Painvision Demo Movie. This demo movie shows step-by-step how an “on-line labeling session” is performed by a pain expert. The movie exists in a Dutch and English spoken version and is already showed in “avant-premiére” during the official opening of MOBILAB (KHK). This demo movie will be used on several occasions like international conferences, workshops, presentation etc., to introduce our project to the outside world!
Furthermore in this editions we present the list of conferences and publications where we introduced our project. On each of these presentations we received good response and useful comments of the audience.
In this “Painvision Newsletter” we also like to remind the members of the user committee that the next meeting is planned on February 29th with the technical workshop in conjunction.

Introduction of the Painvision demo movie

Painvision demo movie

We proudly present the “Painvision Demo Movie”. This demo movie shows step-by-step how an “on-line labeling session” is performed by a pain expert. Together with the recent technical realizations (recording equipment) everyone will have a good view of the practical actions and implications of a “on-line labeling session”. This video covers the major realizations we have already reached in this project and is very useful to introduce new people to our project.

The Painvision Demo Movie can be freely downloaded at our Painvision website. This version contains some English subtitles for further explanation of what is shown on that fragment. Currently we are working on replacing these subtitles by a voice and this in two languages (English and Dutch). This allows us to play this movie without any additional (written) comment. These versions are planned to be released at the end of January.

Acquisition system in the picture

Since November 2007 our new flexible acquisition system is operational in De Wingerd. The main improvements of this version is that the whole acquisition system is build on a movable and resizable platform which enables us to move the system easily form one room to another. To give an impression of the new acquisition system some pictures are presented:

Pain expert performs an on-line labeling sesion on a tablet pc with a software version of painscales and the cameras record the patients face
Recording computer, build in a wooden box and is connected to the wireless network

Fujitsu Siemens Lifebook T4215 Tablet PC

Tablet PC

Tablet PC

To improve our acquisition system we have replaced the touch screen by a tablet pc. The touch screen was used to provide an easy to use software version of the pains scales. But the disadvantage is that the touch screen is not wireless. The cables attached to the touch screen are not practical to use and might disturb the patient. So we decided to replace the touch screen by a tablet pc. A tablet pc is similar to a portable pc except that it has a touch screen and the screen can be rotated 360°. This makes it possible to turn the screen and flip it down in that way you only have a screen visible with all functionalities of an ordinary portable pc. We purchased the Fujitsu Siemens Lifebook T4215 Tablet PC
( On this tablet pc the software to fill out the pain scales automatically will be installed, hence the pain expert will be able to walk in the patients room without struggling with a monitor or cables and has the flexibility to get the best position to observe the patient.


Participation of the ProRISC 2007 workshop

ProRiscWe have submitted a contribution describing our recent technical progress to ProRISC. ProRISC is held in Veldhoven (The Netherlands) on November 29-30, 2007.  More info of this workshop can be found at the ProRISC (STW) home page: Beginning of September we received the great news that we are selected for participating to this workshop. This implies that we have to prepare a flash presentation of maximum one minute, prepare a poster which will be presented during a poster session and write a full paper which will be included in the workshop proceedings. We have chosen to focus on the technical side of the project according the intention of ProRISC, to be a more technical conference. The outcome of this workshop will be published in one of the following newsletters!


Visit to Prof. Jan De Lepeleire, Leuven

A lot of questions arise concerning the way of labeling images and quantify pain based on facial expressions. At the start of the project Professor Jan De Lepeleire was asked to participate as scientific godfather to support the scientific part of the medical branch in this project. So it was obvious to contact Professor Jan De Lepeleire and ask him for his advise. On Thuresday 20th of  September we had a meeting in “Centrum voor huisartsen geneeskunde in Leuven” with Professor De Lepeleire and representatives of the different project partners. It was a useful meeting where first Professor Jan De Lepeleire explained his research project, Qualidem (, where one of the tasks was to measure pain in demented elderly. He underlined that pain often was underestimated in demented elderly. Furthermore he provided feedback on the way we have to interpret facial expression in real-life and on the video images. Once we have defined our labeling protocol (which describes in detail how often, when, how,… a labeling session must be done) Professor Jan De Lepeleire was interested to review this protocol and give feedback on it. We will keep each other informed.



Visit to Dr. Sandra Zwakhalen and Prof. Jan P.H. Hamers, Maastricht University of Maastricht

To quantify pain on a reliable and valid way one can use pain assessment tools, also known as pain scales. There are a lot of pain scales available to quantify pain in elderly. Most of the time these pain scales are in English, but some of them are translated into Dutch. Drs. Sandra Zwakhalen is currently one of the most known experts in developing, translating and validating pain scales. Drs. Sandra Zwakhalen is working at the department of Nursing Science which is a specialist research and educational unit embedded within the Faculty of Health Sciences, Universiteit Maastricht We arranged a meeting with Drs. Sandra Zwakhalen and Prof. Jan P.H. Hamers in Maastricht. The purpose of this meeting was to present our project and to ask for some advise in understanding pain scales and training people who must use these scales to acquire objective pain information. They where impressed of our goal and the multidisciplinary team to achieve these objectives.


[July 20, 2007] Welcome to our new colleague's


Welcome to our new colleague's: Greet Leysens, Dragana Miljkovic and Stijn Quanten!

Greet Leysens will support us in the way to find a reliable and validated way of labeling the recorded images according the selected pain scales. First she will find out how to train the pain experts in using the selected pain scales. Furthermore she will define a protocol which must be followed by the pain experts during the labeling of the patients.

Dragana Miljkovic will join the technical staff. She will develop the label tools to become a better way of labeling the images by the pain experts. These label tools must help us to find out the inconsistencies made during the labeling by the pain experts because of there personal interpretation. Dragana will report the inconsistencies in a statistical way which will be used to better train and optimize the label protocol for the pain experts.

Stijn Quanten will be part of the managing an technical staff. Stijn is the substitute of Erik Vranken, who is leaving this project.
