Fasciculations all over, mostly in triceps, calves, thighs. More on R side. Can create at will w/ contractions. Started 8 wks ago. No weakness, no tripping, slurring, or coordination problems.
37 yr male, overall good health. No focal muscle mass loss, 5/5 strength in all areas Normal gait, slight assym of reflex w/ upper extremeties less than lower, normal response to pinprick and vibration. R lower numbness and tingling from Sciatica.
EMG:
Motor NCS R peroneal nerve over EDB normal.
RNS of R ulnar normal. Sensory NCS of right ulnar and sural sensory normal. Needle demonstrates fib potentials in R tibialis ant, R pronator teres, biceps, & triceps. Scattered fasc potentials seen. Neurogenic MUPs seen in the R L5-S1 myotomes & scattered throughout the R upper extremity, max in the R C6-7 myotome. Some scattered signs of chronic active denervation in the R C6-7 and L5 myotomes. May reflect an early MND; but given the relative focality of the abnormalities & some radicular complaints, need to exclude focal radiculopathies in these areas.
Columns across the top: Spontaneous: IA, Fib, Fasc, H.F., MUAP: Amp, Dur, PPP, Recruitment: Pattern. Everything a "N" except:
R. Tib Anterior = Increased IA, 2+ Fib, 1+ Fasc
R. Gastrocn (Med) = +1 Fasc, 1+ Amp, 1+ Dur
R. T Fascia Lata = 1+ Amp, 1+ Dur
R. First D Inteross = 1+ Red Recruitment Pattern
R. Pron Teres = Increased IA, 2+ Fib, 1+ PPP, 1+ Red Recruitment
R. Biceps = Increased IA, 1+ Fib, 1+ Red Recruitment
R. Triceps = Increased IA, 1+ Fib, 1+ Facs, 1+ Amp, 1+ PPP, 2+ Red Recruitment
R. Deltoid = 1+ PPP
