Thank you. May you please add what you measured this to be? I'm not a health care professional, but I'm trying to measure my own finger. It would be really helpful if you told the different measurements of a normal working hand and maybe also showed us an example of a injured hand. (Or someone pretending to have an injury, showing us the pretended active ROM.)
Thanks for watching. At the beginning of every goniometer video we list the normal ranges for an uninjured joint before we show how to measure. For this particular joint the normal range is 90-100 degrees. We typically do not include numbers in our range of motion videos so the focus is on the technique, not the result. However, In this video the subject has a measurement of about 108 degrees.
