Accelerometry a technique for the measurement of human body movements. The low cost compared to more commonly used gait laboratory equipment. A summary of the indications for new systems of measurement is given with particular reference to the advantages and potential hazards in the use of accelerometers. By using adequately assembled uniaxial accelerometric sensors an easy to manage measurement system can be obtained that estimates the three dimensional position and orientation pampo of a body segment through an appropriate analytical model. A variety of accelerometer designs offer diversity of dynamic range and sensitivity. The paper concludes that improved transducers will allow this method to be extended to the study of the movement of other parts of the body. The popularity of using accelerometer based systems to quantify human movement patterns has increased in recent years for clinicians and researchers alike.
