Approximately 30% of older adults fall at least once a year and 50% of that number will fall twice. Likewise, the number of falls that an older adult may suffer rises with increasing age. Falls have a high morbidity and mortality rate and are considered a major public health problem. It is estimated that 7% of hospital visits by older adults are the result of a fall and 40% of these require hospitalization. This article presents some of the main detection methods and algorithms used for fall detection and discusses their advantages and disadvantages. Each of these methods and algorithms directly or indirectly requires varying processing, connectivity, storage, and portability capabilities and provides varying degrees of accuracy. Based on this analysis, an experimental development for fall arrest in older adults will be proposed that aims to achieve 95% accuracy using a minimally invasive wearable sensor.
