The continued increase in running popularity has led to a subsequent increase in the need to assess running gait more easily and affordably. Although traditional measurement devices such as motion capture systems, force plates, and electromyography are adequate methods of gait analysis, they suffer from several limitations, such as expense and lack of portability. Recent technological advances have made available more viable options such as accelerometers, electrogoniometers, gyroscopes, and in-shoe pressure sensors. These sensors are being used more commonly to acquire the same information as the more traditional systems, without the associated limitations. Combined with wireless technology and/or data loggers, they provide an affordable, lightweight alternative to gait analysis, allowing data collection over prolonged periods of time in almost any environment. This article will review the current technologies used in the analysis of running gait, with a focus upon the latest developments and equipment.
