The test person is asked to copy an instruction video. This is due to standardising scans in the best possible yt . The timing and the action performed should be similar to the video and followed as though looking in a mirror. The software is designed to identify when the person deviates from the general technique and may ask the person to repeat a task. All exercises are commonly used in research and by health providers who assess movement professionally. It should be kept in mind that there is always some natural variation in human movement - this characteristic allows us to accommodate changing environments and avoid overuse injuries from repetitive tasks. The software, therefore, allows for slight personal variations in the way tasks are performed. The variation itself is interesting - this could be a positive attribute for a healthy body.
The exercises are rather simple to follow and easy to perform for healthy, able-bodied individuals who are living independently. The single-leg balance and squat tasks are possible in both ‘Normal mode’ and ‘Easy mode’. Easy mode has slightly different instructions and makes tasks easier through partial weight-bearing and less challenge to balance. Before recording, the test person is asked to rehearse single-leg balance and squat tasks, for safety and to familiarise themselves with the tasks. If they acknowledge that they cannot safely perform before the recording begins, then they will not be asked to do the tasks during the recording. Each task can be performed a maximum of three times, after which the task is ended or it switches to Easy mode. The software is looking for the best possible performance, but safety must come first. The final measure is recorded for reporting.
Postural alignment is associated with energy efficiency, antalgic (painful) postures, deformity, mood, sports, occupations and even optimal breathing. There is no one perfect posture. The best posture is ‘the next one’, as all bodies like to vary the way we stand and sit.
Balance is a function that is essential to independent living and good quality of life. Sway patterns, sway area and sway velocity can tell us a lot about the status of our balance and measured over time, may be a good predictor of falls, especially in the elderly.
Side bending is used regularly for testing for lower back problems. It challenges the spinal column, the ligaments and the muscles around the trunk. When tested regularly, range of motion and control of side bending can be a powerful predictor of existing or potential back problems.
We squat on a daily basis to perform everyday tasks like lifting, walking stairs, running and sitting/standing. The behaviour of the feet, knees, hips and trunk influence the successful squat, and factors that predispose us to injury or discomfort.
