Title: Intervention to Reduce Sedentary Time in Older Adults Undergoing Orthopaedic Surgery: a Feasibility Study (INTEREST)
Brief Summary: The aim of this study is to investigate the feasibility of an intervention to reduce sedentary behaviour in older adults waiting for hip and knee replacements. The study will be a randomised controlled trial design, including 2:1 randomisation into an intervention and usual care group respectively. A target of n=45 patients ≥60 years will be recruited from Russells Hall Hospital, Dudley, UK, approximately 8-10 weeks before surgery, assisted by research nurses. The variable-length intervention, informed by Self-Determination Theory (SDT), will be composed of multiple behaviour change techniques, namely motivational interviewing, individualised feedback on sedentariness, goal-setting, environmental modification, self-monitoring, and social support. Assessments will occur at baseline, 1 week pre-surgery, and 6 weeks post-surgery. The primary outcome will be the feasibility of the trial, assessed quantitatively using study statistics, and with mixed-methods assessment of acceptability, practicality, adaption, satisfaction, and safety via questionnaires given to participants. Exploratory outcomes will include physical function, cardiometabolic biomarkers, measurement of SDT constructs, and both objective and subjective measurement daily activity and sedentariness. The study will last up to 18 weeks per participant.
