Accelerometry provides information on an individual’s habitual physical activity and postures. The transition from sit-to-stand involves the cardiovascular, neural, and muscular systems, and is linked with balance disorders when tested in laboratory conditions. The methodology for quantifying sit-to-stand velocity (STSv) in free-living conditions and the association with participant-level and health factors are unclear. A scoping review of the available literature on free-living STSv was performed to investigate methodology, participant, and health-related factors in relation to STSv. A literature search was conducted across Scopus, EMBASE, MEDLINE, CINAHL, and Academic Search Premier databases (initial 2,098 articles), yielding n = 15 articles that measured STSv using an accelerometer in a free-living condition or in preparation for use in free-living conditions ( n = 10 methodological, n = 5 participant/health-related factors). Sensor type, sampling rate, and filtering characteristics were all heterogeneous, while most sensors were placed on the anterior thigh. There was no consensus for algorithm development to identify sit-to-stand transitions or for the quantification of STSv. Among studies, STSv in individuals with frailty, stroke, and older adults were slower compared with healthy controls. The evidence regarding the utility of free-living STSv is limited but encouraging. The physiological and health underpinnings of preserving or improving STSv using interventional designs are highly warranted. This scoping review identifies literature gaps and recommendations for future investigations. STSv is not limited to controlled conditions only and wearable monitors provide insight into this metric during free-living condition, but harmonized sensor data collection and analytical approaches to quantifying STSv are needed.
