SDN Members don't see this ad. (About Ads) Hi every one! here is a part of an EMG report I've been reading: "Needle examination: left biceps: high frequency polyphasic repetitive discharges at rest, decreased recruitment pattern. Left FDI, left brachioradialis: normal study. Left triceps, left supraspinatus: repetitive discharge with full recruitment pattern" I have been reading about EMG and NCS for hours now! and I could only figure out that there is an evidence of denervation of the biceps but I can't tell what's wrong with the triceps and supraspinatus! Could some one help?
