Protocol of body orientation, shoulder joint and shoulder arch movement for bioimpedance measurement_

Number	Body orientation, shoulder joint and shoulder arch movement
1	Standing straight up position
2	Supine position
3	Sitting and arms straight down and relaxed - starting position (arms straight down)
4	Arms straight forward (90° shoulder flexion)
5	Starting position (arms straight down)
6	Arms behind the back (slight extension in shoulder joints)
7	Starting position (arms straight down)
8	Arms straight out to the side (90° abduction in the shoulder joint)
9	Starting position (arms straight down)
10	Arms straight back (full extension in shoulder joint, retraction in shoulder arch)
11	Starting position (arms straight down)
12	Arms straight up (180° shoulder flexion)
13	Starting position (arms straight down)

Thickness of the two distinguished layers of skin on the right shoulder tissue which were examined using the ultrasound machine for the 10 volunteers_ Layer 1 is epidermis and dermis and layer 2 is hypodermics/subcutaneous tissue_
