Strides for Knowledge – with Our High

How Does it Work?

Piezoelectric materials, especially quartz crystal, yield an electric charge propor-tional to the mechanical load applied. They are the heart of force sensors. Force plates usually consist of a top plate (aluminum, steel or glass) mounted on four 3-component force sensors. Each of these sensors measures the force com-ponent acting on it in three orthogonal directions.

What is Biomechanics?Life expresses itself in movement, mechanics describes movement – this is what lies behind the term biomechanics.Movement occurs only when forces are acting. These can often not be recogni-zed let alone appraised by the naked eye. The magnitude and direction of the forces acting on the body contain valu-able information for orthopedists, coa-ches, shoe manufacturers, ergonomists, neurologists, car makers and many other specialists in the broad interdisciplinary field of biomechanics.

Measuring System for Ground Reaction Forces Forces occurring between foot and ground when standing, walking, running, jumping and sliding. They are accurately recorded with one or more force plates. The BioWare software developed by Kist-ler processes the signals recorded by the force plates and, depending on the appli-cation, provides a series of informative parameters such as:• 3 force components• Resultant force• Direction of force• Center of pressur/(COP)• Torque• Coefficient of friction• Power and energyThese parameters can be recorded stati-cally and dynamically in real time. Even the fastest events in biomechanics can be captured reliably.

Stay Ahead with Quartz Force Plates In all biomechanical measurements, the person being tested must be unaware of the measuring devices and his move-ments must not be influenced by the instrumentation. Kistler force plates can be built into the floor so that they are practically invisible, and can be operated discreetly, easily and safely. Quartz force plates, like all quartz sensors, offer several unique features:• Extremely sensitive yet safe against overload• Large measuring range• Wide frequency range recording even the fastest force changes• Absolutely stable, virtually unlimited operational life• Recalibrations are unnecessary• Reliable and accurate• 5 years warranty on all force plates • Compatible with other systems

The Charge Amplifier Quartz sensors yield electric charge as output signal. Prior to data processing, this signal is converted into a proporti-onal voltage by a charge amplifier. For force plates, the 8-channel charge amp-lifier Type 9865 is mostly used and fully remote controlled by BioWare.Datasheet: 9865E_000-287

Evaluating the Data with BioWare 2812A1The BioWare software system makes the operation and application of force plates extremely simple, but at the same time offers almost unlimited possibilities. Versatile graphics and configurations allow simple, user-friendly working in all applications. Charge amplifiers and force plates are remote controlled by BioWare, allowing the user to concentrate fully on his measurements. Datasheet: 2812A_000-370

BioWare Performance 2812A2The Performance module is tailored mainly to applications in sports. Measur-ands such as work, power, displacement of the body's center of mass (COM) e. g. jumping height, and force gradient are available. Datasheet: 2812A_000-370

The Pioneer in MulticomponentForce MeasurementKistler made history in 1969 introducing the first commercially available force pla-tes. Since then, all over the world, over 1500 force plates have long become the unchallenged standard tool of leading specialists in biomechanics. Kistler is certified to ISO 9000 and ope-rates a calibration laboratory accredited by the SCS (Swiss Calibration Service). This is another guarantee of Kistler’s quality and precision.

An Accurate Picture of an Inaccurate W

Reliable MeasurementsResearch demands accurate measure-ments to enable world-wide exchange and comparison of results. In biome-chanics, the very nature of biological systems makes them difficult to record precisely. Multiple measurements are normally necessary to draw statistically significant conclusions.Kistler force plates are recognized as the world-wide standard; delivering reliable, reproducible results over a very long service life.

VersatilityKistler force plates are a cost-effective investment, since they have a long ser-vice life, and their versatility ensures suitability to any future application. The same force plate measures smallforces just as accurately as very large ones. It can also reliably record even the fastest force impulses.

The force plates can be used in any posi-tion. The inter faces to other systems are simple and reliable. Kistler will gladly provide all technical information on request.

Research and Development Force plates are used in the following three main fields:• Gait analysis in orthopedics, prosthe- tics, rehabilitation and sports.• Explosive events such as impacts and push-offs in sports, in ergonomics as well as in the development of shoes and playing surfaces.• Posturography (maintaining balance) in neurology, psychology, the phar- maceutical industry and orthopedics. Talk to us about your field of application so that we can suggest the best system for you. Kistler is a charter member of the Inter- national Society of Biomechanics ISB and supports its activities as the main sponsor.

Acceleration Sensors A wide selection of single-axis and tri-axial acceleration sensors offers almost unlimited possibilities in biomechanics and other areas of research and indus-try.

Technology Serving Man

Gait AnalysisThe slightest variations and asymmetries in the forces excerted can be captured with force plates. Detecting, changes in the impact force after Achilles tendon surgery, adjusting and wearing-in of a prosthesis, or detecting compensatory loading on the healthy side in unilateral joint injury are a few such examples.

Clear ResultsForce plates provide exactly quan tifi ab le information, essential and indispens able for a reliable diagnosis. Objective state-ments can now be made in or tho pedic, assessment logging the progress of reha-bilitation, and neurology.The subjective judgement "yes, I believe it is getting better" of the past can be replaced by an objective documentation of every improvement.

Simple OperationRoutine application in everyday clini-cal practice calls for simple installation procedures and above all uncomplicated, easy operation. BioWare allows the user to concentrate on the current problem without being disturbed by technical details. Certain force plates such as Type 9286 (with the Walkway Type 9401A) can be set up and operated almost any-where easily.

NeurologyA very low threshold is a must in this field, requiring as it does the accurate recording of the smallest force variati-ons (micro-vibrations) and the slightest shifts in the body's center of mass. Here, the unique property of the piezoelectric measuring principle comes fully into its own: one and the same quartz sensor can measure "grams" or "tons"!

The dynamics of sports place particularly high demands on force plates

Page 12: Kistler Brochure

Sports:

Success Is All

that Counts

Top results in competition are the goal of all training.

Yet, steps of progress are getting smaller and smaller, can only be

visualized by sensitive instruments.Kistler force plates prove successful time and again in optimizing force,

movement and coordination in sports.

Page 13: Kistler Brochure

Top Performance Is the Goal – Kistler S

What Counts Are the Results! Top-class athletes are venturing ever clo-ser to the limit of the loading capacity of the human body. Even the slightest errors lead to excess stress or even injury, which may impair performance for ever. Kistler force plates make a substantial contribution in two areas:• Analysis of stress in competition and

during training. Loading patterns are thereby made visible which even the eye of an experienced coach is unable to discern.

• Monitoring allows optimal training close to the limits, yet warns promptly against overload which could lead to injury. At the same time, the athlete can see his progress towards victory.

High Dynamics The fast explosive events in sports are accurately recorded by Kistler force plates. They feature a very high natural frequency and a high loading capacity, both unique qualities inherent to piezo-electric measuring technology.

Outstanding Advantages Quartz force plates are ideal for all applications in sports.• Versatile: thanks to a wide measuring range and high dynamic reponse.• Simple: largely automated operation.• Safe: thanks to a large overload capa- city and automatic offset correction.BioWare controls the entire system, either with one or two force plates, and allows simple, versatile processing, display and recording of the measured data. Kistler has designed various force pla-tes for very specific applications such as recording the world championship in weight lifting, held 1985 in Sweden.

Sports Shoes and Playing Surfaces Supporting, guiding, cushioning are decisive criteria for shoes. Similarily, playing surfaces must offer good shock absorption and safety against sliding. Leading makers of sports shoes and playing surfaces rely on Kistler force plates for developing and testing new products.
