RunwayScan
RunwayScan is a component of our NeurodegenScan Suite. RunwayScan system meets the needs for gait analysis of animals. Gait analysis allows highly sensitive, noninvasive detection and evaluation of many pathophysiological conditions, such as those occurring in Spinal Cord Injury, Parkinson’s disease, Alzheimer’s disease, ALS, arthritis, pain, neuromuscular and skeletal muscle diseases.
Product Description [PDF opens in new window]
RunwayScan system takes video of animal (mouse or rat) walking on a clear walkway, as input. The video of the ventral view (underside view) of the animal is obtained using one or more high-speed digital cameras. The video essentially captures the foot prints of the animal as they walk/run on the walkway. RunwayScan can work with videos taken from any walkway that allows the capture of its footprints on any video capturing hardware system with a high-speed camera.

RunwayScan can reliably analyze the video, and determine various characteristic parameters that are related to the pathophysiological conditions. These parameters include the stance time (paw on the belt), the swing time (paw in the air), total stride time, stride length, foot contact area size (also representative of foot pressure), body-foot spacing distance (distances between body and feet), foot spacing distances (distance between various feet), running speed, stride frequencies, foot coupling measures (in-phase or out-of-phase gait patterns of feet), and Sciatic Function Index related measures such as foot print placement rotation angle with body and toe spread factors (splay). Also calculated are brake time (early part of stance until the paw reaches maximum contact) and propel time (latter portion of stance when the paw is propelling the body. RunwayScan also provides Whole Body Movement Information, including information about Body Rotation during walking, Body Shifting (lateral and longitudinal whole body movements) during walking. Base of support information including a new measure called Gait Angle is also provided.
System Requirements
- Windows-based PC (XP, 2000)
- Intel high-speed processor (Pentium 4 or better)
- Special videocard for real-time analysis
- Large HDD capacity for storage
- Good lighting conditions
- IR camera or red light for dark experiments
- Video-multiplexer for multi-camera feed
RunwayScan outputs the detailed results of these parameters from analysis into Microsoft Excel files and gives statistical results to meet requirements in the research. Advanced functionalities such as batch mode analysis, group export, direct analysis of AVI captured files, and post-hoc conversion to compressed MPEG videos to save disk-space are available. A sample screenshot of the RunwayScan software is shown below. The stride data is shown on the right for each foot individually. The results are updated as the analysis takes place.
The latest version of RunwayScan now includes two new features – a) Ability to automatically detect outliers in the results so that you can review the questionable results more efficiently, and b) ability to view and export the Ink-Pad like image that shows the placement positions of the various feet.
Complete turnkey systems (including all necessary hardware and software) are available. Custom design of your environment to facilitate analysis, including lighting condition setup, IR/red light setup, cage enclosures, video integration, and video-feed to computer is also available.
