Feasibility and safety of the 30-second sit-to-stand test delivered via telehealth: An observational study.

With screening, the 30STS, performed by telehealth, is a safe and feasible measure of function and lower limb strength. Telehealth exercise testing presents challenges in standardizing the environment and ensuring participant safety. Minimal space and equipment requirements and moderate convergent validity with physical activity provide good clinical utility in this setting.
