Plain English Summary

Background and study aims
Pedometers are portable devices, often attached by a belt worn on the waist. That counts every step a person takes by detecting hip movements. There is evidence to suggest that these devices promote physical activity and improve quality of life in the general population. It is also suggested that people generally don’t increase their physical activity levels after undergoing hip replacement surgery. Here, we hope to use the pedometer to increase levels of physical activity in this group of patients and help them to recover from their surgery.

Who can participate?
Adults (at least 18 years old) who have a hip replacement operation scheduled for 2 weeks’ time or later and are able to walk at least 10m without walking aids.

What does the study involve?
The participants are randomly allocated into one of two groups. Those in group 1 receive standard care following their surgery. Those in group 2 receive standard care and a pedometer-driven
walking intervention (treatment). Each person in this group will be given a target number of steps to walk each week using their pedometer.

What are the possible benefits and risks of participating?
The possible benefits of taking part in the study are that it is helping to understand if physical activity aids recovery following hip replacement. The additional risks on taking part in this study is that there is a slight increase in the risk of suffering a ‘sports injury’ as it is likely that participation in this study will result in participants being more physically active than usual.

Where is the study run from?
University of East Anglia (UK)
