Recent technological developments have led to the production of inexpensive, miniature accelerometer sensors with potential for use in a clinical setting. These sensors can provide reliable information on mobility and objective measurement of gait and balance. Accelerometers have significant advantages when compared with other quantitative methods currently used for gait analysis which are often impractical, unreliable and costly. Accelerometers are currently used mainly in a research setting, however, with recent advances incorporation into clinical practice is possible.
