Sensorimotricité

Presentation

The sensorimotricité platform of Paris Cité University is on 7th floor in Saints-Pères. It is operational since November 2007. The platform has 200 m2 local room including a large room  used to record the subjects, a waiting room, a bathroom with a WC, a doctor’s office, a researcher’s office and an engineer’s office. Our 4 partners are the CNRS, INSERM, Paris Descartes University and IFR Handicap. We have had 600 000€ since 2007 to equip the platform. A Motion Capture and Movement Analysis system is available in the platform. It includes 6 units of 3D active motion capture device Codamotion CX1 for measuring body movement, 32ch Delsys EMG high-performing device Trigno Wireless System for the muscle activity detection, 2 force platforms AMTI for the pressure centre measure. One Immersion 3D visual projection system provides the visual input during a movement. The equipments are used for research to investigate motor control and sensorimotor transformations in healthy Human, in high-level athletes, in astronauts and patients. Different medical field are concerned in the latter case:  ENT, psychiatry, neurology, rehabilitation. The users are the researchers from the EPST, coach, members of the space agency and PU-PH from various hospital departments. They have published altogether more than fifty papers in various journals since the opening of the sensorimotricité platform.
The scientific projects on the platform can require either a CPP, an authorization from the CERES if minimally invasive or are reviewed by the staff of the platform if they are not invasive at all.
The platform allows studies on populations of various age, from infants to senior.

Codamotion 3D Motion Capture System

Hardware

A CX1 uniquely identifies each marker with 100% reliability, so 3D marker trajectories are available for immediate analysis and display on a host computer with achievable latency (delays) of less than 0.5 milliseconds, perfect for real time applications.
The captured field expands at 1.6 x the distance from the CODA unit. Nominal operating range is between 2.0m and 4.5m from the unit (nominal capture volume approximately 75 cubic metres), though it is possible to go out to 10m and beyond with high power markers under normal laboratory conditions.

  • Physical Dimensions Weight of unit: 5kg Dimensions (L x W x D): 800x112x80mm
  • Resolution Standard deviation in position of a static marker at 3m range (axes as Figure 2): ˃ 0.05mm (X and Z axes) ˃ 0.3mm (Y axis) Resolution as fraction of field of view: ˃ 1:70,000 (X and Z axes) ˃ 1:12,000 (Y axis)
  • Sampling Rates vs. Marker Numbers ˃ 100Hz for 56 markers ˃ 200Hz for 28 markers˃ 400Hz for 12 markers˃ 800 Hz for 6 markers
  • Real-Time Latency ˃ 0.5 milliseconds for applications using CODA SDK.˃ 5-10 milliseconds using Codamotion Analysis or ODIN software suites.
  • Capture Volume ˃ The linear capture range expands at approximately 1.6 x the distance from the CODA unit. Maximum accuracy is achieved between 2.0m and 4.5m from the unit, as in Figure 3. ˃ The total capture volume within which maximum accuracy is maintained = 75 cubic metres.

Software

The ODIN software platform is familiar to movement analysis researchers, clinicians, and biomechanists around the world. ODIN takes you through the entire 3D movement analysis process including:

  • Data acquisition from multiple sensors and measurement devices
  • Real-time monitoring of data inputs
  • Long-term data storage and retrieval
  • Analysis of 3D and spatio-temporal data, and display of results
  • Sharing of data and protocols with others in the same location and remotely

AMTI Force Platforms & Walkways

To understand the kinetics (forces, torques, moments, powers) within the skeleton as a human moves, movement data from a Codamotion system can be combined with information from AMTI force platforms.

Not only is it easy to acquire synchronised force data in the Codamotion ODIN software, but a full set of kinetic analysis methods are available to automatically compute joint kinetics and present it alongside the kinematic information.

The AccuGait-Optimized (ACG-O) is AMTI’s portable solution for quantifying human gait and balance.

BioSemi Electroencéphalogramme (EEG)

Hardware

The BioSemi « Pin-type » Active electrode has been designed especially for mounting in BioSemi headcap’s. The electrode has a sintered Ag-AgCl electrode tip, providing very low noise, low offset voltages and very stable DC performance.

Standard sets have 32 electrodes on a common connector with 140 Centimeter cable length. (Other cable lengths are available on request.) The electrode is completely resistant to long term water and alcohol submergence enabling easy cleaning and disinfecting. The electrodes are numbered with water-proof stickers for easy channel recognition.

Software
All BioSemi systems are delivered with acquisition software based on the LabVIEW graphical programming language from National Instruments. This standard package handles the basic functions like data acquisition, display on screen with all usual scaling and reference and filtering options, streaming to disk in .BDF file format and network sharing.
