Figure 4From: Comparison of muscle activity in the empty-can and full-can testing positions using 18F-FDG PET/CTComparison of mean maximum SUVs of the muscles in the full-can testing position. The middle deltoid showed the greatest increase of muscular activities among the six muscles in this position. The middle deltoid and supraspinatus showed significantly greater muscular activity than the anterior and posterior deltoid, infraspinatus, and subscapularis (P < 0.001).Back to article page
