MPASS: Mizzou Point of care Assessment System
Mild Cognitive Impairment Video Concussion Video
The Mizzou Point-of-care Assessment System or MPASS (Patent Pending) is designed to provide portable and affordable in-clinic assessments that incorporate multiple aspects of motor function including static and dynamic balance, reaction time, and athletic movements. The platform includes microphones, speakers, and LED displays to easily incorporate and assess dual-task activities. MPASS applications include diagnosis and monitoring for concussion, mild cognitive impairment, fall risk, frailty, anterior cruciate ligament return to play, sport performance, injury risk, knee/hip arthroplasty, and other clinical and rehabilitation applications that assess human movement. Motor function, postural control, dual-tasking, and reaction time are impaired for individuals who sustain a concussion and individuals with cognitive impairment. The MPASS combines lightweight portable force plates, markerless motion capture, and reaction time measurements to provide a more affordable and a more precise multi-dimensional assessment solution. The system is designed to be inexpensive and portable and MPASS motor function assessments typically take less than 15 minutes.
MKATS: Mizzou Knee Arthrometer Testing System
MKATS Video Abnormal knee motion has been linked to injury risk and pathology. Methods to accurately measure bone motion during dynamic activities, particularly non-sagittal plane motion, are not currently available in the clinic. Marker based methods to measure tibiofemoral motion are limited by skin artifact. Radiographic methods, such as dual fluoroscopy, are limited by high cost and limited access to specialized equipment. The MKATS (Patent Pending) is a portable device that accurately measures three-dimensional tibiofemoral motion during dynamic activities. The MKATS uses electromagnetic motion sensors and clamps fixated to bony landmarks of the distal femur and proximal tibia. A series of calibration steps and computational algorithms determine the knee axis-of-rotation and anatomical axes. Flexion-extension, varus-valgus, and internal-external rotation angles are reported during dynamic activities such as step-up. The device has been successfully used to measure tibiofemoral motion efficiently and accurately during functional activities in the clinic.
The images show the MKATS during a step-down task for a subject wearing an ankle foot orthotic (AFO). The graphs show differences in knee motion (20 subjects) for step-down activities with (AFO) and without (Control) an ankle foot orthotic. Statistically significant differences in knee motion have also been measured between healthy and ACL deficient populations.
