The sit-to-stand (STS) movement is a key functional movement critical to independent living. This movement is physically demanding to conduct, especially in older adults, and in the presence of physical impairments associated with a range of conditions, such as stroke, osteoarthritis, Parkinson disease and hip arthroplasty. A limited capacity to perform this movement increases the risk of falls, dependency and increased support for personal care and rehabilitation. Restoring independence in this movement is, therefore, considered a priority for physical rehabilitation.
