Infrared light is reflected off of special markers placed on your hips, knees, and ankles. A computerized camera system will capture the exact motion of these markers which will identify the movement of your body while you walk. Muscle Function Measurements Small electrodes may be placed over certain muscles on your skin to measure how those muscles are working when you walk. The electrodes on your skin will measure the EMG and help determine if there is a problem with your muscles or nerves. Acceleration Measurements Small, light-weight cubes known as accelerometers may be used to measure how much shock goes up your leg when your foot hits the ground.
Many problems can arise if there is too much shock.
Accelerometers will measure this shock and can help researchers and your doctor decide on the proper treatment to reduce shock. Diabetes is often accompanied by poor circulation and a loss of feeling in the extremities, all of which could result in ulceration and possible infection. As a diabetic, if infection does develop and advances to gangrene in your feet, amputation may be necessary. Gait analysis is used to determine which areas of your feet take the most pressure while you walk. Preventing an ulcer from forming or helping an ulcer to heal by properly managing the pressures on the bottom of your feet could significantly improve the chances of saving a limb from amputation.
