Facilities and Test Capabilities
Our facility is located on the campus of Wake Forest University Baptist Medical Center. This newly built facility has state of the art equipment, over 2000 square feet of laboratory space and a 12 foot high ceiling. Featuring a 30 foot walking track with a 3D optical motion capture system. The space also includes office space with computers for lab staff and students.
Our Digital Real Time System consists of 10 Digital Cameras and software to capture complex motion with extreme accuracy. Real-time capabilities allow us to see captured results as the task is being performed. These cameras use reflective markers attached to the body to triangulate locations in 3 dimensional space. Four force plates imbedded into the floor are used to measure ground reaction forces. Using data collected from the camera and the force plates, we are able to calculate joint forces and moments for a variety of movements including walking, running, throwing, jumping, kicking and swinging.
Motion Capture for Human Movement Motion Analysis
Quantitative movement analysis is useful in identifying the underlying causes for movement abnormalities in pathologic patient groups such as in patients with knee osteoarthritis or cerebral palsy. The results of the motion capture system have been shown to be useful in determining the best course of treatment in these types of patient populations. Patients and controls will participate in 3-Dimensional biomechanical movement analysis testing to evaluate initial differences in variables between pathologic and healthy controls. This work will help to determine if surgery and physical therapy improve these movement parameters over time and to what extent.
Electromyography (EMG), is described as an experimental technique describing the neuromuscular activation of muscles within postural tasks, functional movements, work conditions and treatment/training regimes. A variety of disciplines use EMG to provide insights into how we perform movement which include: biomechanists, physical therapist, clinicians, and strength coaches. Subjects will perform movement tasks while neuromuscular activity is recorded. This work will provide us with the basic knowledge of how motor units are recruited in certain musculature for a given movement task. Electromyographic (EMG) equipment is used to measure the activation of individual muscles. These data can be used in combination with the camera and force plate data to account for muscle co-contraction (agonist and antagonist muscles activated simultaneously).
A virtual reality system uses a green screen to allow children to see themselves immersed in a video game to reduce the discomfort and increase compliance during rehabilitation.
Novel Pressure Distribution Measurement System
The Novel pressure measurement system captures dynamic in-shoe pressures as well as pressures as measured on a mat revealing, interaction between foot and footwear or body and appliance. Applications for a plantar pressure system include: screen for disorders secondary to diabetes or other neuropathic issues, observe movement disabilities, and regulate weight bearing after surgery. Other applications involve tissue pressures while sitting, standing, rolling or performing other functional activities.
A NeuroCom Balance Manager System is used to evaluate the contributions of the vestibular, visual, and proprioceptive systems on balance control. Another instrument measures the distribution of pressure on the bottom of the foot while walking.
