Pressure Distribution Measurements (Novel USA, Novel GMBH)
Pressure Distribution measurements are used to monitor the local loading on the tissue. Currently, our lab has three systems to measure pressure distribution: the Novel EMED Platform System for barefoot measurements, the Novel Pedar In-shoe System for measurements within footwear, and the Novel Pliance Seating System for seated measurements. All systems use capacitive sensor technology.
Motion Monitor (Innovative Sports Training)
The Motion Monitor is a three dimensional, magnetic-based, kinematic sensing system which allows movement of body segments to be captured in real time at capture rates up to 140 samples per second. Information obtained in a kinematic assessment include position, velocity and acceleration of a body segment or joint. Sensors are placed on body segments that are tracked instantaneously during the movement performance. From these data, one can provide a quantitative assessment of the movement pattern.
The Motion Analysis System is used to determine three dimensional kinematic information about a movement performance. Information obtained in a kinematic assessment include position, velocity and acceleration of a segment or joint. Reflective surface markers are typically placed on segments that are tracked frame by frame throughout the movement performance. Our lab has eight video cameras that are synchronized used to track these markers at rates between 60-480 samples per second. From these data, one can provide a quantitative assessment of the movement pattern.
Bertec Force Platforms
The force platform is used to measure the ground reaction forces during various activities. Forces are measured in the vertical, anterior posterior and medial lateral directions. Data is often combined with motion analysis measures using link segment modeling to calculate joint moments and joint reaction forces.
Delsys Electromyography (EMG) Systems
EMG records the electrical activity of a muscle by placing electrodes on or in some cases within skeletal muscle (depending on the type of electrodes used). The EMG system consists of an amplifier that is interfaced with a computer. An amplifier is used to make the electrical signals larger since the electrical activity associated with muscle activity is so small. Several muscles can be monitored simultaneously during the movement performance to see the relative amount and sequence of muscle activity.
These are used to measure joint position. These are often used in conjunction with EMG recordings.
Photoelectric Timing System
These are used to measure walking speed. Photocells are interfaced with a digital clock. When a subject crosses in front of one photocell the clock is started and the second photocell stops the clock as the subject passes. To convert this timing measure to speed we measure the distance between the photocells and divide the distance traveled by the elapsed time. These are often used in conjunction with pressure, force and kinematic measures so that speed can be monitored.
Impulse Training System
This is a training device that has been studied in the lab.
CSMI Norm Isokinetic Dynamometer and Handheld Dynamometers
Isokinetic measurements are measurements of muscular torque at a constant velocity. The computerized isokinetic dynamometer monitors and alters the resistance so that the movement velocity is held constant. Movement velocities can be determined at various velocities (up to 300 degrees/s). Typically, a joint is measured and the maximum torque output is calculated for that movement. This equipment is located in a therapeutic exercise room in the Health Science Center. We also use a variety of handheld dynamometers to objectively measure strength.
