Measuring shoulder internal rotation range of motion: a comparison of 3 techniques. A study on human upper-limb muscles activities during daily upper-limb motions. This study showed highly reliable shoulder joint ROM measurements in healthy adults using the Kinovea software. The inter-rater reliability ranged from an intraclass correlation coefficient value of 0.95 to 0.98, whereas the intrarater reliability ranged from an intraclass correlation coefficient value of 0.98 to 0.99. Shoulder flexion, abduction, and external and internal rotation ROM were measured with the patient in supine position.
Intrarater reliability was examined by a single rater within the same day. Shoulder joint ROM was measured in 52 healthy individuals (mean±SD age was 26.7±4.2 years) using Kinovea photographic measurements by three trained raters.
Angle tracking in kinovea software#
This study was conducted to investigate the inter-rater and intrarater reliability of Kinovea software for measuring shoulder joint ROM in healthy individuals. However, the software’s reliability in measuring shoulder joint ROM has not been studied. Kinovea software is a recent video-based method that uses a virtual goniometer to obtain values for the ROM of joints. With modern innovations in technology, new methods other than the universal goniometer have been applied.
Moreover if an angle can be automatically tracked, it will be more powerful.Goniometry is a tool used frequently for measuring and documenting range of motion (ROM) during a physical therapy examination. I wonder if there is any good and rapid image recogintion algorithm suitable for it. If the tracking function becomes more accurate, it will be better. I wish kinovea will be evoluted to a versatile and sophisticated sport analysis solution. I changed the geolocalisation of the site to england, and it should be reachable from China within the next few days Hello, Joan I thought the way as to place three cross markers along the apex and two lines, and then to compute the angle frame by frame. If the tracking function can automatically track the change of angle in a video, it will be more helpful.
Angle tracking in kinovea upgrade#
Is there any way to upgrade the image recognition precision without losing the speed? In the world of image recogintion, there are a lot of algorithms as I heard of. The semi-automated tracking function works but in some case it loses the target.
I am very pleased to tell you that I can get access to Kinovea - Video Analysis Software for Sports now. I changed the geolocalisation of the site to england, and it should be reachable from China within the next few days Ok, a range of french IP from the web host were blacklisted by the chinese Great Firewall. I you can reach, there is a quick demo of it at the end of this video. (The tracking is somewhat easily lost, as the tracked object passes behind something or change shape, etc.) If you aren't satisfied with what it came up with, you can adjust it manually at any time. Then, when you move forward in the video, it will try its best to macth the object and will draw the trajectory. You first add a drawing of type "cross", then right-click it and choose "Track Trajectory" in the contextual menu. There is a semi-automated tracking function.
