EasyAngle - flexion of the interphalangeal joint of the thumb

Order at: meloqdevices.com/collections/all
Start by placing the client/patient’s hand on the table surface, with a forearm supinated. Align the upper end of the ruler with the proximal phalangeal bone, start the measurement, after which you instruct the client to perform the flexion. Bring the upper ruler segment in the line of the distal phalangeal thumb bone and end the measurement.

Mhhh, they set the other side of the measurement. Is it supposed to do that? The flexion shouldn't be 120 degree :D

Hi, the device always measures 180 Degrees. As you see in the video EasyAngle show you Main angle and supplementary angle (the smaller one displayed on the screen). In this case the flexion was 59 degrees. Kind regards
