Dynamic hand grip sensor analysis

 

pliance® hand sensors

The pliance® hand sensor family has been designed for:

• accurate and functional diagnostics of hand pre- and post surgery
• evaluation of rehabilitation progress
• ergonomic assessment during occupational activities
• biomechanic and orthopaedic research

novel systems are based on calibrated, accurate and reliable capacitive sensors. The individual sensor elements are elastic and arranged in a matrix, which conforms to 3-dimensional shapes. The sensor matrix is connected to the novel pliance® electronics hardware. The pressure analysis can be done on- or off-line by a PC or a handheld personal digital assistent (PDA).

pliance® cylinder sensors
The pliance® cylinder mats are specifically designed for measurement of pressure distribution and contact forces while gripping a cylinder. This measurement can be used for standardising functional diagnostics at different hand locations. A definitive comparison of hand function pre- and post surgery is possible and the progress during rehabilitation can be objectively evaluated.
The mats are available in various sizes so the user can select different cylinder diameters to accommodate hand size or other testing requirements.

prothesis

The pliance-RLS prosthesis system has been developed for socket evaluation and fit. It provides a quantification of the level of pressure at the residual limb/socket interface during static and dynamic movements.

As a result of their design and material selection, the pliance-RLS sensors are flexible and elastic and have the ability to conform very well around highly contoured sites. This is particularly advantageous in prosthetics because of the highly irregular surface and geometry of the residual limb and the shape of the socket.

The pliance-RLS sensors include a dense array of sensors, with a small individual sensor area. This allows recording of interface pressure at a discrete location of the socket. The length of the sensor pad is appropriate for use on a short or long transtibial socket.The different standard shapes allow testing of different
anatomical areas simultaneously. Custom made sensors are also available.

saddle

pliance®-s test system

The pliance®-s system marks the beginning of a new era in the assessment of the dynamic inter-action between the horse, the saddle and the rider.

How does the rider sit?
How does the saddle fit?
What does the horse feel?

pliance®-s measures the dynamic pressure distribution between the saddle and the horse using a thin elastic sensor mat.

It is possible to assess quantitatively the commands of the rider and the subsequent reaction of the horse. The technique of the rider can be objectively assessed and corrected. Data can be immediately viewed with easy to use software.

Using pliance® recorder software, the dynamic pressure distribution can be directly compared to synchronized video pictures.

Harmful pressure points that arise from poor saddle fit can be recognized and corrected. During dynamic movement, such as trotting and gallopping, substantially higher loads occur on the back and the shoulders of the horse as compared to standing. The pressure distribution under the saddle during dynamic movement of the horse can be measured in order to assess the fit.

The pliance®-s sensor mat contains 2 x 128 sensors which are scanned with a scanning speed of 20,000 sensors per second. Dynamic measurements can be recorded for all paces, from the walk to the gallop.

Gait asymmetry of the horse, possibly associated with physiological back problems or poor saddle fit, can be assessed quantitatively. The pliance®-s system is accurate and reliable. The sensor mat is calibrated in a simple, computer- aided procedure which calculates the calibration curves for each individual sensor. The calibration remains stable with time.

The pliance®-s software operates as a Windows application and displays dynamic pressure distribution on screen as a 2D or 3D color picture. The pictures can be printed in their original size to allow the user to relate the pressures precisely to the horse’s anatomical landmarks or to the saddle.
All data are fully compatible with novel scientific software packages and can also be exported in ASCII format.

With the help of the pliance®-s system and its powerful software one can analyse the quality of the saddle and obtain a better understanding of the interaction between the rider, the saddle and the horse.

wheelchair

The pliance-HS wheelchair systems offer the state of the art technology for static and dynamic pressure distribution measurement on wheelchairs.

The new pliance-HS wheelchair system provides a dynamic quantification of the sitting pressure points of patients in wheelchairs.

This system helps in selecting the appropriate cushions and correct adjustments of the wheelchair to fit the individual patient. For real-life testing, all measurements can be done dynamically while the wheelchair is moving. The pliance functions with Bluetooth® wireless telemetry systems in a wide measurement range. The telemetry allows the user to watch the patient in the wheelchair and at the same time fully control the testing from a PC.

pliance wheelchair sensor mat
The system consists of a not only flexible but also elastic measuring mat, a multi-channel analyser, a calibration device and a software package for Windows XP computers. As in all medical measuring systems the most important part is the sensor technology. pliance works with accurate capacitive transducers in a matrix configuration. The elasticity of the sensor mats permits perfect conformability to 3-dimensional deformations. The pressure transducing elements contain high-tech materials manufactured by novel. Restoring force, range of force, threshold, hysteresis, temperature effect, frequency response and other characteristics are tailored to optimal use on wheelchairs.

With the aid of the trublu calibration device, all pliance-HS sensors
are individually and simultaneously calibrated with homogeneous air pressure. Calibration guarantees accurate and reproducible data collection.


pliance-x electronic analyser
connects up to 1024 sensors to a desktop, notebook PC or handheld Pocket PC. The software is written for Windows operating systems and allows a wide range of scientific analysis. Collected data can be stored on the internal flash memory or transmitted online to a PC or Pocket PC via the built-in Bluetooth® telemetry.


pliance wheelchair software
The pliance software operates as a Windows application and allows easy data collection. It contains many useful methods of data collection and analysis of dynamic pressure distribution. It also allows continuous data storage in online mode and data handling with a configurable SQL database.
