Studying for the boards and came across your video. There are some errors in this video. Arms behind the head is only external rotation. It does not test internal. You demonstrated abduction and adduction not horizontal abduction and adduction as stated in the video. This would be horizontally across the chest. The MMT was not explained and only shoulder flexion and elbow flexion and extension were performed without explanation of your findings. Also, hand placement for shoulder flexion MMT should not be across the elbow joint. Hope this helps out others preparing for the exam.
