ortho.lab –
software and systems for video-based motion analysis
Catching a fly in your hand is incredibly difficult. At a rate of 20
individual images per second, the human brain is slow to detect
movements. If more than 20 images per second are displayed, the
human eye turns this sequence into a film. If a fly were to sit in front
of the television, it wouldn’t see a film, it would see a slow sequence
of individual static images. This also helps the fly to keep avoiding
the hands that try to grab it. In contrast to humans, flies can take in
around 200 images per second.
Video-based motion analysis
Using video technology and special software, professional motion
analysis systems adapt this form of vision. There are a wide range
of technical options for generating reproducible images which are
objective for several observers. Cameras in mobile phones, tablets and
HD camcorders can generally already take in significantly more than
25 images per second. The best option for the quantitative recording
of images of complex, rapid motions is high-speed cameras which can
record up to 125 frames per second.

PRO.vision TWIN
Software for video-based motion analysis
PRO.vision TWIN is both introductory analysis software and an addition to PRO.vision 2D and 3D. With PRO.vision TWIN, even videos
which have been recorded by an individual, whether they have been
recorded with a simple camcorder or several high-speed cameras,
can be analysed. PRO.vision TWIN also contains a database and video
management system which is delivered as software.

PRO.vision TWIN
Functions
Whether videos are recorded on the treadmill or while walking freely,
on a smartphone or with a stationary camera, you can save or upload
them into PRO.vision TWIN and analyse them using the extensive
analysis tools. A wide range of tools are available to the user for the
analysis:
•• comparison and manual synchronisation of up to 32 videos
•• manual drawing of the angles on a static image
•• video processing: various measurement functions and drawing
tools such as zooming, moving and rotating the video; static and
dynamic stroboscope;
•• cutting and compressing videos; superimposing videos (mix); video
tiles (split)
•• recording from 1-4 cameras
•• creation of individual automatic reports (via an individual MS Word
template)
•• database for recording and managing videos as well as customer
data, patient history data, measurement data, video recordings
and reports
Intuitive drawing of angles and lines

3. Open the video in PRO.vision TWIN
4. Carry out the static image analysis using the drawing tools
(e.g. manual drawing of the angles)
5. Generate and print the report

PRO.vision 2D
Movement analysis system to record 2D data with automatic
recognition of LED markers using a high-speed camera
The PRO.vision 2D system works on the basis of coloured LED
markers. The system follows markers placed on the patient using a
high-speed camera and provides the results live with the option for
these to be presented in a PDF report. This means analyses can be
carried out very quickly – the process lasts no more than five minutes from preparation through to the creation of a report.
If necessary the data can be further processed in MS Excel.
The software is self-explanatory and easy to use. It is easy to
upgrade from PRO.vision 2D to PRO.vision 3D as necessary.

Bio-feedback
Through innovative livemarker recognition, PRO.vision 2D offers the
possibility of using so-called bio-feedback. When the user performs a
movement outside a set range (e.g. a squat, hip angle from the front
or knee angle from sagittal), a signal sounds.
Bio-feedback, the technical feedback about the body’s own processes,
helps the user to be aware of wrong patterns of moving, which he
often does not perceive via his own senses.
18
Using a sound signal (movement is wrong) or a signal that does not
sound (movement is correct), the user receives acoustic information as
to which movement has to be corrected. Movements can be repeated
multiple times in order to internalise the learning process.
www.streifeneder.com/op
Execution:
•• produce own measurement
•• set movement range
•• attach markers
•• start recording
•• perform movement

PRO.vision 3D
Movement analysis system to record 3D data with automatic
recognition of LED markers using two high-speed cameras
Using the latest 3D software and two high-speed cameras, in addition to individual gait analyses (sagittal, frontal and dorsal), dynamic
motion analyses of the spine (including rotation of the hips and
individual segments of the spine) can be carried out precisely in just
a few minutes.
Two calibrated cameras are used to process data in 3D. Using this
data, parameters can be measured parallel in 3D without having
to install cameras in every level. The measurement is carried out
in the same way as with PRO.vision 2D. The difference is that just
one calibration of the cameras has to be carried out before the
measurement can be taken. This step is carried out using a special
calibration board which is positioned in front of the camera. The
software calculates the position of both cameras relative to one
another, equalises the edge areas in the camera image and thereby
achieves significantly higher measurement accuracy. PRO.vision 3D
is portable, very user-friendly and can also be used as a 2D system.
