Service                  Lab,             footscan                  broke many records as a young athlete. He was frustrated to
                                                                    see how many training partners failed to perform well

and             Runners                       Service               because of ever returning injuries. His own Achilles tendon
                                                                    kept him of the track more then once. Therefore, he decided
Scan INTERNATIONAL                                                  to deepen his podology knowledge and specialise in running
                                                                    shoes. On the left side of his shop, he kept his television
business, but at the right side he started a sports shoe advisement shop. TV-Sport was born. Jempi had one ultimate purpose: to
help as much people as possible in staying injury free. Today, the footscan system Jempi developed is spread all over the world to
be used by hospitals, universities and even national armies to analyse gait and successfully prevent injuries.

                                                                              From the start Jempi chose to base his shoe-
                                                                              advise on scientific literature and own gait
                                                                              analysis. At that time, different shoe brands
                                                                              developed        varus       and    valgus-shoes,
                                                                              protecting       athletes     against   excessive
                                                                              pronation or supination, but nobody really
                                                                              knew how to advise the correct supporting
                                                                              shoes. Jempi made this possible by filming
                                                                              the athletes while running on a treadmill.
The images of different shoes were analysed and compared on a television screen. Based on this video-image
analysis, correct shoes could be advised.

The demand for gait analysis and effective shoe-advice boomed. Already a year after opening TV-Sport was
renamed Runners Service. The televisions disappeared from the shop and were replaced by a tuned
photocopying machine. Athletes took place on the copier, who was baptised as PODO MID, to make an
image of their feet. That image was analysed and compared with the running video images. In that way static
foot-type (normal, flatfoot and high arch foot) and overpressures were visualized.

The analysis of many running video-images led to the conclusion that running shoes, even expensive ones,
don’t always give the correct support to someone’s feet. Because no foot is alike, the running shoes and
insoles need to be adjusted individually. For example, people who suffer major difference in leg length need
to compensate that difference with shoes of different height. Jempi went to ask advice from his orthopaedic
technician in Antwerp, and in 1984 he decided to complete an orthopaedic technician training and sport
podology course in the Netherlands.

Right picture: Although the PODO MID was
a creative and innovative device for foot
analysis, it only works for static analysis.
Running injuries mainly have a dynamic cause,
so running patterns need to be analysed with a
dynamic device.

Dynamic systems already existing on the market were very
expensive at that time. This led to the development of the PODO
SCAN in 1984. A system, consisting of 1000 sensors was able to
measure pressure patterns under the feet with a speed of 100Hz.
The Podo-scan could visualise the centre of pressures in one
dimensions (Z). This was another great step forward for Runners
Service. Now, the results of the pressure measurements could be
combined with the treadmill running images to advice foot-type
corrISPOnding shoes and, if necessary, adjust the shoes at the
orthopaedic lab.

From 1985, Jempi Wilssens became a member of The Flemish
Sport and Science federation. This is an organisation that
assembles sport doctors and physiotherapists to share their
knowledge. Above that, Jempi was asked as shoe consultant of
Adidas France. Adidas, nor other running brands, had anti-
pronation or other foot-type adapted shoes at that time. Together
with Jempi and Runners Service, Adidas wanted to develop such running shoes and consequently improve
their quality.
In 1986, an internal study was set up at
the RSlab - Adidas sports laboratory. A
total of 650 runners (and their injuries)
were analyzed and followed up. The
study found that most suffered running
injuries were Anterior Knee Pain, Ilio-
tibial band syndrome, Patello-femoral
disorder, Medial tibial stress syndrome,
Stress fracture tibia/metatarsal, Plantar fascitis and Achilles tendonopathy. These results were confirmed by
a study of the University of Brussels.

Every possible injury-linked parameter was involved in the study. The athletes were classified by suffered
injuries, training surface, intensity and quality of training, quality of running shoes and worn-off pattern of
the running shoes. The images taken from the Podo-scan were analysed together with the treadmill running
video-images and worn-off shoe pattern to determine if the athlete wore the correct foot-type
corrISPOnding running shoes. Wrong running shoes are those who don’t give the correct support for the
specific foot type of the athlete. For example, a heavy pronator who runs with neutral cushioning shoes.

Five worn-off shoe patterns were found:
1) Normal: with wear at lateral heel and total forefoot (25% of all runners)
2) Diagonal Pronation: wear at lateral heel and medial forefoot (45%)
3) Overpronation rearfoot (15%)
4) Supination rearfoot (10%)
5) Supination rearfoot and forefoot (5%)
Adidas and Runners service NV concluded that thirty percent of all injuries are caused by training errors,
like a wrong training program (12%) or too fast increasing training distance (9%). The running shoes, and
most of all wrong running shoes, appeared to be the major cause for injuries. It was remarkable to see that
not the quality or over-use of running shoes caused injuries, but 44% of all injuries were caused by wrong
running shoes. So the key to injury-free athletes lies in giving correct shoe advice.

       Too fast increasing miles             9%                   over used running shoe       11%
       Other causes                          9%                    wrong running shoes         44%

The original Runners Service shop became too limited for intensive gait analysis. So in 1989 Runners Service
moved to a shop where there was more space for running analysis. A running track of 20 meters where
athletes could run barefoot and an orthopaedic laboratory were installed. The shop was renamed Runners
Service Lab and the customers could already appeal to six running experts. In cooperation with different
gait-analysing centres in Mol, Kampenhout, Bruges… Runners Service scanning expanded through Flanders.

1994      Runners Service scanning
Robert Louis-Dreyfus, former chief executive officer (CEO) of Adidas, asked the Adidas laboratory and
Jempi (as international advisor for Adidas) to search for a system that can help to advise a foot-type
corrISPOnding running shoe. At that time, anti-pronation and motion control shoes were in full
development. Dreyfus wanted Adidas to be the first running shoe brand that could advise an absolute injury-
risk-free shoe.

First the Adidas labo (Adidas scanning) chose for Tekscan, an already existing
pressure measurement system. But the system soon appeared to be insufficient for
intensive running analysis. The pressure plate broke because of the multiple
running tests and the software could never serve for intensive gait-analysis.
Therefore, Jempi proposes Dreyfus to develop an own pressure measurement
system in cooperation with Intersoft Electronics NV, a company working in the
field of time measurement since 1983.
Already after one month, it seemed that the RS scanning system would exceed the expectations. CEO
Dreyfus was excited en asked RS scanning - Intersoft to create a footwear adviser. And because he wanted to
be the first, Dreyfus asked the cooperating companies to bring fast result. Three months after Dreyfus’s
request, he could successfully present a new (Adidas) gait-analysing system at the ISPO of 1995 at Munchen.

                                                                                         Picture left:
                                                                                         The adidas footscan

While Adidas chose to use the system for commercial applications, there was a growing interest of doctors
and universities for the system. At 1995, RS scanning (Jempi) got a member of the interest group for foot-
biomechanics (ISB), an organisation who gathers specialists in foot-biomechanics. Two years later, Jempi
Wilssens gave a presentation on the ISB foot congress in Tokyo about footscan and injuries. The results of
the earlier study of 1986 were compared and confirmed by newer measurements with the footscan plate.

Because of the growing international need for the footscan system, RSscan INTERNATIONAL was
established as a joint venture between RSscan and Intersoft Electronics NV. The purpose was to adjust the
marketing and the production towards each other, and to launch the footscan® product on the international
market. The company intensified its Research and Development of scientific hardware and software
designed for podology, podotherapy, revalidation, physiotherapy, orthopaedics (surgery and shoe-
orthopaedics), neurology and physio-osteopathy. From the start, RSscan International had the mission to
keep developing a revolutionary pressure measurement system.

Since then, the development of footscan® pressure measurement applications enlarged. Next to improved
pressure plates, a footscan® insole system was developed. The flexible insoles consist of approximately 350
sensors for each sole and scan at a constant frequency of 500 Hz (500 Hz left and 500 Hz right). These soles
are linked with an interface that writes the data on a SRAM-memory card.

Another improvement of that time was the footscan® 3D system (patent), who created the possibility to
scan the plate up to 500 Hz. This is a special interface giving the possibility to implement 3D forces
measured by a force plate. A dynamical calibration can be performed by this system assuring perfect stable
and absolute values from the pressure plate. This interface has the possibility to send out trig./sync. TTL
signals, FM triggering and to receive trig./sync. signals from other equipment, like EMG, video and active
and passive marker cameras.

2000    D3D
Since 1995, RSlab scanned over 25.000 feet. With every scan new knowledge about the link between
injuries and different static and dynamic foot-types was found. At the RS laboratory shoes and insoles were
adapted or reinforced to correct foot movements with a high injury risk. By following up athletes treated at
RSlab, Jempi Wilssens and his team of gait-analysts learned more and more about injury prevention. This
trial and error method led to the creation of D3D insoles. With a stable shoe and individualized D3D
insoles, RSlab could keep many athletes injury-free.

D3D made it possible to combine different applications, by using different materials such as EVA, PU and
hard plastics, depending on different needs. A D3D insole is assembled from a base part, orthopaedic insole
(OS), correction elements and a top cover. D3D is used as an injury-prevention for professional and amateur
athletes. By testing the ready made orthotics in the shoes and by walking or running over the footscan®-
plate, the balance screens will help to analyse the data and to find the correct solution. It is easy to
reproduce an identical pair of insoles without the differences due to the manual involvement.

2002: Launch of the footscan® USB system: a dynamic pressure measurement plate, connected by the USB
port of the PC. The footscan USB plate has a dimension of 50cm x 40cm with 4096 sensors and a data-
acquisition at 125Hz.
2003     ISB FOOT congress New Zeeland
At the ISB foot congress in New Zeeland (2003), RSscan in cooperation with the University of Gent
presented three important studies1. The timing, pressure and movement ratios of walking were compared
with the same ratios while running. This study concluded that gait measurements, used to make orthotics,
need to be made with different running-speeds and separate for running and walking.

Another study2 compared barefoot, insole and ground pressure measurement during 5m/s running. The
pressure platform and an insole-system were synchronised to determine which information is given by a
pressure platform and which by an insole – system. The two different pressure measurement systems
produced different results for Centre of pressure pattern, balance line and M1&2 curve. One of the reasons
for these differences is that the insoles move and bend with the shoes. Another aspect is that the pressure
platform measures the shoe-to-ground interaction, where an insole measure a foot-to-shoe interaction. Not
only differences between the two systems were found in the results, also differences between the four
running conditions occurred. To compare athletes or patients, it is necessary to start from the same test
protocol with the same testing shoes.

                 Test protocol: two pressure platforms (2m x 0.4m) mounted in a 30 m long running
                  way. Synchronised insole and ground pressure measurements at a running speed of
                                            5.07m/s (+/- 0.39m/s).

2004: RSscan International launches the footscan® USB2 plates, connected by the USB2 port of your PC.
This connection makes it possible to reach a frequency of data-acquisition of 300Hz.

Footwear Adviser
Many years of research and development, scientific and RSscan own studies, led to a first version of the
footwear adviser software in 2004. This software makes it possible to analyse dynamic foot-type and to
advise the ideal supporting running shoe. An advice is given not only for the foot as a whole, but also for the
rearfoot, midfoot and forefoot in specific.

                                                                         Left picture: The Footwear Adviser is

                                                                         and this for a training amount of 100
                                                                         kilometres per week. The average of their
                                                                         running pattern was calculated and an
                                                                         ideal curve appeared. Based on this ideal
                                                                         “injury-free” curve, the type of running
                                                                         shoes can be determined.

Nevertheless, it has to be kept in mind that the curve with running shoes can slightly differ at the rearfoot
during initial landing. Barefoot heel landing occurs more medial then with running shoes on. The running
shoe makes faster ground-contact on the lateral side, causing more supination during landing. Besides this,
barefoot and shod running is comparable.

                                                             Left picture: the RSscan Footwear Adviser proposes
                                                             a shoe type, based on the gait analysis. This runner
                                                             for example is advised to wear neutral shoes. The
                                                             software also proposes detailed extra support (down-
                                                             left on picture). This can be very useful for the
                                                             development of running shoes.
Right picture: The ultimate purpose of the footwear adviser is
to adjust running shoe models to the proposal of the system. In
cooperation with Fusion, a Danish sports brand, RSscan
developed three running shoe categories: 40, 60 and 80. With
40 as a neutral cushioning shoe, 60 for medium anti-pronation
support and 80 excessive anti-pronation support. These
categories can be advised, based on the footscan measurements.

2005     Jempi Wilssens started teaching foot biomechanics in podiatry at the Universities of Barcelona,
         Sevilla, Madrid and Beijing.

2007     from pressure measurement to skeleton movement
Based on different studies, RSscan started to take the first steps into the exiting world of modelling motion
in 3D using only plantar pressure data. Lake M. et al., 2005, discussed the possibility to use plantar pressure
variables for the simulation of internal/external rotation at the ankle joint. Dixon S., 2004, found that it was
possible to distinguish different inversion/eversion ROMs of the rearfoot using lateral/medial CoP ROMs.
Hagman F., 2005, studied the possibility to use plantar pressure to predict foot motion. Hagman proposed a
mechanical model that simulates heel motion, only based on pressure measurement.
                                                                  Left picture: in cooperation with AnyBody
                                                                  Technology, RSscan developed software to represent 3D
                                                                  motion of the lower limb, based on footscan data

                                                                  presented at the ISB congress of 2007 in Taipei,
                                                                  consists of three parts: heel impact, midstance and
                                                                  forefoot propulsion. In the 3D model, 26 bones plus
                                                                  tibia and fibula are made visible.

The great advantage of this 3D model lies in the simplification gait analysis. Engineers, doctors and experts
can talk about statistics and other rough gait data. For “normal” people, it’s more difficult to really
comprehend how a wrong pressure pattern under the feet can influence pressure in the above bones and
joints. Doctors can show their patients 3D movements and explain them the use of good supporting shoes
and insoles.
                                  Animal gait and evolution theory
                                  As the RSscan footscan pressure measurement systems spread around the
                                  world to different clinical and university centres, also the range of
                                  applications broadens. Many non-human studies were done in cooperation
                                  with RSscan. Kristiaan D’Aout (University of Antwerp, Belgium) studies
                                  the gait of many different sorts of animals. Purpose is to map the walking

2008       Scientific proof for the footscan predictive and preventive abilities
A study3 of the Brittannia Royal Naval College (Dartmouth), 2008, concluded that injury rate of military professionals
can be predicted and reduced with the RSscan footscan® system. This was the first and largest randomised controlled
study ever undertaken worldwide to compare orthotic use with injury-reduction. The RSscan Footscan system succeeded in
dividing recruits in three risk categories (low, medium and high) and after a period of using the D3D orthotic system, a
reduced injury rate of 31% was found.

For many years, the army suffers a high drop-out of new entry trainees caused by (mostly lower limb)
injuries. For the soldiers injury means loss of income, while the army has to cope with extra costs. The cause
of lower limb injuries can be of many kinds, but an abnormal running pattern seems to be the most present.
Different studies4 show that every year between 30 and 70% of all recreational and competitive runners get
injured. For professional athletes and militaries, which are dependent on their body to gain income, injury
means a disaster for the career. Although civilians don’t always lose income, injury can hinder daily life.
Therefore, a method of reducing injuries is of great interest for public health, individual morbidity and
career success.

Notwithstanding the current measurement equipment of IR 3D cameras in combination with EMG and force
plates, it’s still very difficult to draw running patterns and to connect them with possible risk patterns of
overuse injuries. The RSscan footscan® system is, because of his high frequency, of great value in the world
of biomechanics and athlete support.

Casual runners can very well protect themselves against running injuries by wearing personal advised shoes,
adapted to their foot type. For professionals it’s a bit more difficult. Small faults in running pattern can
already cause injury during periods of heavy training. The advantage of footscan is that it is a system that can
depict small abnormalities and consequently serve for predictive and preventative measurements.

Predictive power of RSscan
RSscan footscan system® is used by many sports institutes and universities to scout athletes and help in
keeping them injury free. The national army of Australia, Belgium, Holland, Germany and America already
use the pressure measurement system to evaluate the injury risk of the recruits. Different studies use RSscan

Figure above: A footscan® pressure platform placed in a18m long running way
To determine the predictive power of the RSscan Footscan® system a study was set up by the Britannia Royal Naval
College5. 640 military new entry trainees participated. They were asked to walk barefoot over an 18m track with an
integrated 1m RSscan footscan system® platform. Five complete right and left foot strikes were recorded and analysed
using the RSscan Footscan system ® 7.0 software. After analysis, the biomechanical risk of each recruit was graded in
low, medium and high risk.

The footscan® system measures the vertical force that is applied by the body through the foot to the ground
during the stance phase. Because of this, it is
possible to calculate pressure by knowing the area
that the force is being applied over. The system
detects maximum pressures/forces applied in these
different areas, and the timing of this application of
force. This allows a detailed analysis of when and
where force is being applied during the stance
phase. If there is an imbalance occurring in any of
these key stages, the D3D™ section of the software will highlight where the imbalance is, and the type of
correction suggested.

        Beijing Olympics, One Dream One World

                  Li Ning lights china’s Olympic flame
Beijing – During the opening ceremony of the 2008 Beijing
Olympics, the Li Ning Company Limited made a remarkable
appearance. Founder and Chairman Li Ning lit the cauldron at
the final act of the opening ceremony. Li Ning is a well-know
Chinese gymnast and entrepreneur who embodies he modern
Chinese spirit. As a young athlete from Guangxi, one of the
poorest provinces of China, and as a member of the Zhuang, a
Chinese ethnic minority, he won 6 medals at the Los Angeles
Olympic games of 1984. After his successful career as a
gymnast, Li Ning successfully founded Li Ning Company
Limited in 1990. Not evident at that time, as China was
suffering economic downturn and international boycotts.
Nowadays, the Li Ning Company Limited is a publicly traded
company and China’s largest sports retailer. During the
Beijing Olympics, the sports company was no official sponsor,
but had a remarkable influence on many athlete

The supremacy of the Chinese Olympic athletes at the Beijing Olympics was immense. RSscan
International and Li Ning Company Limited were part of this Olympic fairytale. The Chinese sport
shoes company Li Ning was the first to use the RSscan footscan measurement system in China.
Since 2004 the two companies cooperate in the research and development of professional high
quality sport shoes. The Li Ning biomechanical shoe centre at Beijing is equipped and supported by
RSlab Beijing and serves as a biomechanical test lab to improve the technical quality of Li Ning
sport shoes. During the preparation period for the Olympics, the Li Ning sponsored Olympic
athletes were frequently tested at RSlab Beijing to develop personalized training and competition Li
Ning shoes. So the least you can say is that RSscan International and Li Ning Company Limited
provided a strong foundation for many athletes on their way to Olympic success.
               Tia Hellebaut jumps to historical gold
              Years of preparation led to first Olympic gold medal in Belgian women athletics history

                           Four years ago, Tia Hellebaut changed her athletic orientation from long jump
                           and heptathlon to an intensive specialisation in high jump. At that time, she
                           suffered from a hallux rigidus who limited her abilities during training and
                           running. Successive injuries of the left foot kept the high jumper absent from
                           the track. Tia’s doctor advised her to stop competitive sports, but the
                           motivated athlete and her coach Wim Vandeven disagreed.

                           After one day of testing with the footscan plate at the RSlab and on the
                           outdoor track, Tia’s first unique orthodics were made. The irritation of the
                                                     hallux decreased and Tia could restart her training.
                            Tia Hellebaut cele-      With renewed motivation and energy, Tia Hellebaut
                            brating her gold         trained almost without pain in South Africa. After

                            jumping 2.05 meter       that winter, the footscan tests were intensified.

The          footscan-picture
(walking) showed high
pressures      under       the
metatarsals compared to
other foot parts. Both feet
also show an initial medial
landing with pronation
directly after landing L>R
(high risk of Achilles tendon
problems). Because Tia can’t
use the left rigidus hallux
correctly, the propulsion
force of the right hallux is

The footscan image while running (footscan picture bellow) shows clearly that Tia Hellebaut is a forefoot
runner. Also during running, Tia is not able to use the left rigidus hallux normally and she needs to
compensate with more propulsion on the right hallux.

The footscan measurements led to the conclusion that Tia needs sportshoes with a good forefoot rocker
and a strong, stable midfoot. Further, the D3D orthodics were adapted to add more Metatarsal Support
(now used in the footscan D3D products under the name of MS sole). An A+ element was put on to
give support on the correct place.

the results to adjust the technical training and finally improve the high jumping movement. Theoretical
know-how and analysis were used to treat and prevent sports- and “daily life” injuries. Wim and Tia did
big efforts, but their believe in Gold was strong. With an unbelievable result!
    Samuel Sanchez wins first footscan D3D Olympic gold!
Spain’s cyclist Samuel Sanchez accomplished his dream of
