Tennessee Health Managment - Rehab America Biomechanics Laboratory (Motion Analysis Lab)
Mission of the Tennessee Health Management - Rehab America Biomechanics Laboratory:
To provide the Memphis medical community with state of the art computer assisted motion analysis; to quantify and advance the understanding of the musculoskeletal system by studying human movement and joint biomechanics.
Clinical: To provide exceptional clinical service to patients referred for evaluation. To integrate physical findings, through motion analysis, in the decision making process for patient care.
Research: To collaborate with multiple disciplines to optimize the effectiveness of evaluation and treatment of motor dysfunction caused by orthopaedic or neurological disorders. Dissemination of results through peer reviewed publications and presentations.
Education: A unique learning and teaching environment for students of all allied health and medicine professions, through education and group projects.
Motion Capture System:
Eight high speed (3,000 frames per second) /high resolution (3 mg pixel) Qualisys cameras are used to record the position of small retro-reflective markers attached to specific bony landmarks. Software processing is manipulated to create a 3-D image of the subject. Kinematic data is generated to identify specific joint movement and/or gross patterns of motion. Additionally, two floor mounted force platforms collect concurrent kinetic information to provide information on joint moments and powers. Finally, muscle activity is collected using up to 16 channels of wireless electromyography. Surface or fine wire electrodes are used to identify the specific muscles active during an activity. The simultaneous application of 3-D capture, force plate data, and EMG activity allows researchers and/or care providers to identify and monitor movement dysfunction.
In addition to Motion Capture technology, the Tennessee Health Management - Rehab
America Biomechanics Laboratory also has:
A portable computer-based system that measures both temporal and spatial parameters of gait based on footfall pressures. The GAITRiteÔ system uses a 12-foot long electronic walkway that contains grids of pressure-sensitive pads encapsulated in a carpet connected to a serial port of a Windows PC. The pressure pads scan thirty five times a second to accurately provide temporal and spatial parameters of gait for subjects weighing over 45 pounds.
The Biodex Offset Unweighing System and Gait Trainer 2 Treadmill
The Gait Trainer 2 Treadmill is a treadmill specifically designed with a true zero starting speed. It has the ability to reverse direction for both forward and retro walking, with an incline and decline range of -12 to 15º. It is can be programmed to monitor temporal and spatial gait parameters and provide the user with real time Audio and Visual Biofeedback. When indicated, the Biodex Offset Unweighing system can be used in combination with the Gait Trainer 2 Treadmill. The Unweighing system provides single point dynamic suspension with the option for pelvic stabilization. The system is suitable for use with children and adults.
The Biodex Balance System SD™
The Balance System is a versatile tool to test and train balance. It allows for both static and dynamic balance assessments and can be used as a training device by providing real time biofeedback.
