Wearable technology refers to any electronic device that can be worn on a user's body. This technology is used extensively in medical devices, accessories, jewelry, and clothing. In rehabilitation medicine and strategy, decision-making requires an assessment of the effect of rehabilitation interventions on people. Now, medical practitioners are using wearable technology in medical set-ups to assist in physical therapy and rehabilitation because wearable devices can provide information that can add to the information generated by observing the patients. It ranges from simple monitoring of everyday activities to assessing individual’s independence and mobility levels. It also emphasizes incorporating small sensors to improve the function of devices patients use to carry out motor tasks that they would otherwise be unable to perform. This book elucidates the prospective developments with respect to innovations in wearable technology and their application in rehabilitation medicine. It is a vital tool for all researching and studying wearable technology.
