The concepts of muscle activity generation driven by upper limb kinematics

Table 1 List of all exercises considered for this project, each task is repeated 18 times

Simple motion	Shoulder flexion
	Shoulder flexion (mix)
	Shoulder extension
	Shoulder abduction
	Shoulder abduction (mix)
	Elbow flexion
	Elbow flexion (mix)
	Elbow flexion with a supinated forearm
	Wrist flexion
	Wrist extension
	Wrist pronation
Combined motion	Shoulder abduction with simultaneous elbow flexion
	Shoulder flexion with simultaneous elbow flexion
	Shoulder abduction with simultaneous wrist extension
Complex motion	Breaststroke
	Relay handover
	Reading a clock
	Diagonal reach
	Waving gestures
	Drawing a circle
	Pointing to three points in space*

All simple and complex movements were performed to a natural joint maximum. Shoulder flexion and abduction were performed only to 90 degrees. Movements with the addition of (mix) are performed with arbitrarily changing endpoint, i.e. the subjects are allowed to stop their movement before their natural joint maximum. *This movement is just performed by the test subject
