Triaxial Accelerometry Study
This study aims to understand how much people move years after having hip surgery, either a total hip replacement or hip resurfacing. Arthritis can make movement difficult, but while these surgeries reduce pain and improve function, we don't fully know their long-term impact on physical activity. Researchers are inviting people who had one of these hip operations about 15 years ago to take part. Participants will wear two small activity trackers: one on their wrist for 10 days and another on their thigh for 48 hours. They will also answer a few short questions about their activity. The information gathered will help doctors improve care for future patients by understanding which surgeries lead to more active lives.
At a glance
What is this study about?
When you have hip arthritis, everyday things like walking or even just getting around can become really difficult and painful. Luckily, there are operations like a total hip replacement (called Total Hip Arthroplasty or THA) and hip resurfacing that can help fix this, easing pain and making it easier to move. We know these surgeries are good for reducing pain and improving how your hip works in the short term.
What we don't know as much about is how these surgeries affect your physical activity levels many years later. Staying active is really important for your overall health, so understanding if one type of hip surgery helps people stay more active in the long run is crucial. This study is designed to try and find these answers. By comparing how active people are long after their surgery, we hope to learn more about how different operations affect your daily life.
The findings from this study could be very valuable for doctors. It could help them decide which type of surgery might be best for different patients and also improve advice and recovery plans after surgery. Ultimately, this research aims to help more people live active and healthy lives for many years after their hip operation.
Key takeaways
- This study looks at long-term activity after hip surgery.
- It helps compare two types of hip operations: total hip replacement and hip resurfacing.
- You'll wear small activity trackers on your wrist and thigh.
- You'll also answer a few questions about your activity.
- The results could help improve future hip surgery care.
- Participation is entirely voluntary, and your information will be kept private.
Who may be eligible?
To be part of this study, you need to have previously taken part in a specific research study at Rijnstate hospital. This earlier study happened between 2007 and 2008.
If you were part of that original study, you're likely eligible for this follow-up study. There aren't any other specific rules that would stop you from taking part.
Essentially, the main thing is that you need to be someone who was involved in that particular research trial at Rijnstate hospital about 15 years ago.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Did you have hip surgery between 2007 and 2008?
- Did you take part in a previous research trial at Rijnstate hospital around that time?
- Are you able to wear small activity devices for up to 10 days?
- Are you willing to answer some questions about your physical activity?
- Are you able to provide your consent to participate?
What does participation involve?
If you decide to take part in this study, you will be asked to do a few things. First, you'll fill out some short questionnaires about your physical activity. Then, you'll wear two small activity trackers, called accelerometers.
You'll wear one of these devices on your wrist, usually your non-dominant hand (the one you don't write with), for 10 days and 10 nights. The other device will be worn on the thigh of the leg where you had your hip surgery for 48 hours (2 days). These devices are small and will measure how much and how intensely you move.
There are no medications involved in this study, and you won't need to visit a clinic specially for this. All you need to do is wear the devices as instructed and fill out the questionnaires. The total duration of your active participation will be the 10 days for the wrist tracker and 2 days for the thigh tracker, plus the time to complete the questionnaires.

Common questions
What is the main goal of this study?
The study wants to see how active people are many years after having different types of hip surgery (total hip or hip resurfacing).
What will I have to do if I join?
You'll wear two small activity trackers (one on your wrist for 10 days, one on your thigh for 2 days) and fill out some short questionnaires.
Are there any medicines involved?
No, this study does not involve taking any medications.
How long will I be involved in the study?
Most of your active participation will be during the 10 days you wear the wrist tracker, plus the time to fill out questionnaires.
Will my personal information be kept safe?
Yes, all your data will be kept private and your identity will be protected.
