Measurement of Trunk flexion/extension

Re: Measurement of Trunk flexion/extension

Hi Joanne,
One way is to take a video or photo and pass it through KINOVEA, kinovea.org.
You can measure angles, distance etc.
Another easy way is with inertial Motion Units, accelerometers etc. But this is more expensive and needs some design.

Hi,

and is there anyone know if a person doing flexion 30 degrees, how many degrees act on each spine joint?

Any help is appreciated.
