Methods
ADVERSE EVENTS
This assessor‐blind parallel randomized controlled trial included community‐dwelling Jolder Japanese adults with frailty and pre‐frailty. Fifty‐eight eligible participants were randomly allocated to intervention and control groups. Intervention participants performed 3–5‐min sessions of Radio‐Taiso one to four times per day for 12 weeks. Feasibility criteria were set at practice and retention rates of ≥75%. Safety was monitored by assessing all adverse events reported by participants during the intervention period, irrespective of causality. Potential effectiveness was exploratorily assessed using items that allow clinical interpretation of changes: mobility and health‐related quality of life (HR‐QoL), assessed using the modified short physical performance battery (SPPB) and the SF‐36, respectively.
