The photos show the location of the electrodes for the electrical stimulation. In order:

• Deltoid muscle (red – anterior deltoid, blue – posterior deltoid)
• Deltoid muscle – medial deltoid
• Biceps brachii muscle
• Triceps brachii muscle – long head
• Thumb Abduction

• Flexor digitorum superficialis muscle

• Pronator teres muscle
• Exensor digitorum muscle

The photos show the location of the electrodes for EMG. In order:
