Effects of Limited Wrist Motion and Forearm Rotation on Scapular Kinematics and Muscle Activity During Spoon-Feeding in Healthy Young Adults.

Middle deltoid and biceps brachii activities increased significantly, with a nonsignificant trend toward higher upper trapezius activation.

Taken together, these results demonstrate that the restriction condition required greater activation of the middle deltoid and biceps brachii, with a strong trend toward.increased upper trapezius activity, indicating higher proximal muscular demand during spoon-feeding when wrist motion was restricted. 3.3.
