Information for people who are having a walking movement scan
Clinical movement analysis is a technique that allows very accurate measurements to be made of the way your limbs move.
Movement analysis uses cameras to track small reflective markers placed on your skin. The markers are attached using skin-friendly sticky tape.
The technique is very safe and only uses visible light to record body position. The positions of the markers are used to recreate your skeleton within the computer, the same way modern computer graphic films are made. We use the same technology as Hollywood, only more accurate.
What will happen during the scan?
- Someone will explain exactly what will happen.
- You will be invited to change into your shorts and t-shirt / top.
- Your height, leg length and knee and ankle width will be measured.
- Small reflective markers will be placed on your skin (see picture).
- You will be asked to walk, barefoot, along a walkway (about 10 metres / 30 feet) approximately 6 to 10 times.
We will make video recordings of your movement to help with the analysis of your results. We collect this data to support your healthcare and maintain data quality.
How long will my scan take?
Your scan will take approximately 45 minutes.
What should I bring with me?
You should bring:
- a pair of loose-fitting shorts that can be rolled above the knee
- a top/ t-shirt that can be rolled up to your belly button
- any orthotics, insoles, prosthetics that your clinician has asked you to bring for the scan. Please ask them to make sure you have the right devices for the scan.
What happens after my scan?
You will be able to go straight home after your scan. Your results will be sent by letter to your clinician and available via MyChart (if you are registered on that system).
Your clinician will discuss the results with you at one of your future appointments.
Can I bring someone with me?
Yes, a relative or friend can accompany you during the scan.
If you have a problem with moving, your doctor or therapist may request a movement scan to help them plan your care. Movement scans can help to understand:
- whether the treatment you are being given is effective
- the underlying cause of your pain or movement problem
Movement scans are very low risk. The main risk are trips and falls but no more than when walking generally.
There may be some reddening of the skin where the markers are placed but this should disappear quickly.
