Research summary
This study aims to assess the feasibility of a study to reduce sitting time in older adults ≥65 years undergoing orthopaedic surgery. The main outcome is feasibility, assessed with study statistics and by using a questionnaire at baseline, pre-surgery, and 6-weeks post-surgery. Additionally, the study will assess the feasibility of performing a number of health and function measures, including wearing a physical activity monitor to measure sitting time and physical activity, blood samples to assess indicators of health, a physical test known as the short physical performance battery (SPPB), body mass index (BMI), waist-to-hip ratio, short form mini nutritional assessment (SF-MNA), a self-report measure of older adults' sedentary time (MOST), Basic Psychological Needs Scale, and international physical activity questionnaire (IPAQ). In addition to these, the EuroQol Five Dimensions Questionnaire (EQ-5D), EQ-VAS will be used to assess quality of life, and the Oxford Hip & Knee Score for pain related quality of life. The study is using 2:1 randomisation into an experimental (intervention) or control group (usual care). Three assessment points will take place: baseline, pre-surgery, and 6 weeks after surgery. All measures will be done at baseline and pre-surgery, with selected outcomes at 6-weeks after surgery. During the behaviour change intervention, which is designed using Self-Determination Theory, participants will set their own goals to reduce their sedentariness in specific contexts in their daily lives. Goals will be set after a group motivational interviewing session, in which education about the risks of sedentary behaviour will be conferred. Modifications to the home environment and bi-weekly phone calls will further encourage participants to achieve their sitting time reductions. It is hypothesised that the experimental group will have reduced pain, improved function and well-being post-surgery. The results of this study will aid the design of a future clinical trial.
