Posture Scan requires a person to follow simple audio and video instructions. The software records full body movements during carefully selected tasks. The recording in done in 3D video at 30 frames per second. For optimal recording and measurement, there are certain requirements for suitable clothing, responsibility and behaviour.


Posture Scan records the surface of the body. It works best with tight fitting cotton clothing, underwear, bare skin or tight fitting non-reflective training clothing so the sensor can see the true outline of the body. Below is a list of clothing requirements, along with possible issues and how to resolve them. Clothing made from unsuitable material for IR scans will be detected by the intelligent software. This occurs after the registration process and just prior to the start of recording. To ensure that data error is minimised, the system will ask for the unsuitable item to be removed. Alternatively, the person can abort the test.

To avoid disappointment, we advise providers to inform the end users of the clothing requirements well ahead of time.

Clothing issues/requirements Solution
A jacket, wide brimmed hat or additional accessories disrupt the natural outline of the body. Remove accessories.
Oversized clothing like baggy basketball shorts or an oversized shirt will disrupt the natural outline of the body. Remove the oversized clothing for accurate tracking of the head, shoulders, hips, knees and the ankles.If unable to remove the clothing then pin it using a paper clip tightly behind the body part. Ensure to roll up pants to see the ankles,and pin loose cloth tightly behind the limbs.
A dress will disrupt the outline of the body Do not wear a skirt or a dress.
Shoes may affect the balance of the person, and may be reflective. Remove shoes before the scan.
Loose hair or long hair in a ponytail will hang to the side during side bending, and the software may confuse the hair with the shoulder, causing false results. The hair should be tight on the scalp in a bun behind the head, not above the head. Tracking data should always be checked in Movement Lab.
Full body tattoos might not be detected by the sensor. Cover the skin with tight clothing to improve the tracking.
Some fabrics in some clothes contain synthetic or reflective material, which does not work well with the sensor. Examples include some stretch jeans, reflective fabric in training gear, and Kevlar motorbike trousers. Removing the clothing is the only way to continue with the scan.


Qinematic values safety, privacy and personal integrity. Prior to a scan, individuals are asked to give informed consent by ticking the box on the screen. They are giving permission to the scan provider to control their personal data. They also agree to undertake the tasks at their own risk, and to ask for assistance as required.

 Consent of the individual

Every individual who does a Posture scan is given the opportunity to agree to the Privacy Policy statement before proceeding with the scan. This is to ensure that an individual understands that their data is processed by Qinematic, and controlled by the Organisation or Provider. The Privacy Policy is summarised at the start of every scan, and the full text can be read via a link. Ticking the box is considered giving informed consent.

In Europe, in accordance with the GDPR, children under the age of 16 must have parental consent to allow a Provider to control their personal data.

Providers are asked to be aware of thier local obligations


Safety of the individual

Safety is extremely important for Qinematic. For technical reasons, the service is limited to accommodate people with all four limbs, and whom can stand and walk independently without assistance or an assistive device. Attempting an exercise is only recommended if an individual is confident that they can perform a task  voluntarily. Exercises should not be performed if there is any risk of falling, injury or significant discomfort. To avoid any accidents, individuals and Providers should consider the physical, sensory and cognitive abilities of the test person before starting the test. Poor cognition, poor eyesight, poor hearing, poor balance, pain, fear of falling or fear of pain can affect function. Always practise the squat and balance exercises before the scan begins, to help the software determine the level of ability. Only continue with a scan if the Provider and the test person are sure that the exercise can be performed safely.  Ask for assistance if in any doubt about ability to safely perform a task.

The basic criteria for the test person to do the exercise safely is if they can stand independently on 1 leg. As a general rule - if they live at home alone, can ascend/descend a step or stairs safely and without a rail, then they should be safe. If they cannot go down stairs without a rail, then they probably need supervision, or should not do the tests.

Always remind an individual to practise an exercise along with the instruction video. This will help familiarise them with the tasks, and improve repeatability. To allow a scan at lower levels of function, the software will activate ‘Easy mode’ for partial weight bearing in single leg stance and single leg squat. After three failed attempts at these tasks, the exercise will end and go to the next task. The final attempt will be recorded.

Identification of the individual

It is best to use a consistent Personal Identification (PID) system to identify test persons. The PID can be an email address that is memorable and tends to follow a person for thier lifetime. It can also be a personal number or membership number. Teams or researchers may use a coded system to keep people anonymous, and keep a separate register of names.
