Motion assessment

Being able to measure movement has always been a challenge in many branches of medicine.

Objective measurements offer valuable information in order to diagnose and treat pathologies. For instance, following the onset of a stroke will be crucial to assess a patient’s motion during the rehabilitation time, and to quantify deficits or impairments. It will be necessary to evaluate recovery of voluntary movement and basic mobility in order to deliver a fast and accurate diagnosis and treatment. Motion capture technologies are able to detect and quantify a significant change in the motor abilities of these patients from admission to discharge.

This particular strength of motion analysis systems has also proven to be useful for insurance companies and their hospitals in order to detect and measure injuries and musculoskeletal disorders, and to provide objective data for physical assessment.

Optical motion analysis systems

Clinical 3DMA and EDDO have been widely used in motion analysis. Clinical 3DMA is an affordable solution that is suitable for labs with permanent setups, and allows for full-body analysis. EDDO is suitable for ‘portable labs’. Each of them makes use of its own hardware but both are built upon the same software with the following functionalities:

  • Over 400 analysis protocols available: gait analysis, joint analysis, balance analysis, etc.
  • Real-time feedback: 3D view, plots, numerical data.
  • User-defined biofeedback rules.
  • Synchronization with additional devices such as EMG, force and pressure platforms, etc.
  • Sub-milimetric accuracy for marker tracking.
  • Robust and tested technology.

Inertial motion analysis systems

iSen provides an incredibly fast feedback. It uses a set of STT-IWS sensors (IMUs), which are bluetooth and portable. The number of sensors to be used depends on the nature of the analysis. A single joint analysis (ankle, knee, elbow…) requires two sensors. iSen is a young technology compared to optical systems, but has a long way ahead. Its main features are:

  • No cameras, no specific workspace or lab.
  • Few ‘items’ on the patient’s body: As few as 2 for a joint analysis or 7 for a gait (lower body) analysis.
  • Run the software directly in any Windows desktop or laptop computer – no need for additional devices.
  • Real-time feedback: 3D view, plots, numerical data.
  • User-defined biofeedback rules.
  • Synchronization with additional devices such as ENG, force and pressure platforms, etc.
