The deltoid muscle generates maximum force during upper limb abduction, indicating its crucial role in this movement.
At 30° to 50° of abduction, the muscle activity is most pronounced, highlighting specific functional contributions during motion.
The modeling approach included six joints, measuring force generation both unloaded and with a 2 kg weight for accuracy.
As abduction surpasses 50°, rotator cuff muscles shift to support mode, demonstrating dynamic muscle involvement.
