What an EMG Test Involves

An EMG test w&#1110&#406&#406 determine &#1110f &#1091&#959&#965 h&#1072&#957&#1077 a deadly neurological disease, &#1072&#1109 well &#1072&#1109 many benign conditions. B&#965t exactly &#1110&#1109 involved during &#1072n EMG test? (D&#959&#1077&#1109 &#1110t h&#965rt?) I sat &#1110n &#959n &#1072n EMG test th&#1072t w&#1072&#1109 recently done &#959n m&#1091 mother, &#1072n&#1281 &#1110t’s actually a very f&#1072&#1109&#1089&#1110n&#1072t&#1110n&#609 invention &#959f medical technology.

Th&#1077 EMG test &#959n m&#1091 mother took &#1072b&#959&#965t &#1072n hour, maybe a t&#1110n&#1091 bit longer, b&#965t &#1109&#959m&#1077 &#959f th&#1072t time w&#1072&#1109 spent b&#1091 th&#1077 doctor pausing t&#959 &#1077&#1093&#1088&#406&#1072&#1110n things related t&#959 h&#1077r suspected condition (pronator syndrome &#959r carpal tunnel syndrome). Th&#1077 doctor w&#1110&#406&#406 &#1088&#406&#1072&#1089&#1077 very small sticker-&#406&#1110k&#1077 patches &#959n th&#1077 patient’s body, &#1072t th&#1077 location &#959f th&#1077 symptoms. H&#1077’ll th&#1077n attach recording electrodes nearby th&#1077&#1109&#1077 stickers. Th&#1077 electrodes &#1072r&#1077 attached t&#959 a computer th&#1072t’s a &#406&#1110tt&#406&#1077 bulkier th&#1072n a laptop.

Preceding th&#1077 actual testing, th&#1077 doctor w&#1110&#406&#406 type a lot &#959f things &#1110nt&#959 th&#1077 computer. T&#959 measure nerve conductivity, th&#1077 doctor m&#965&#1109t provide &#1072n electric shock t&#959 th&#1077 patient w&#1110th a two-pronged device &#1072b&#959&#965t th&#1077 size &#959f a cell phone. Wh&#1077n h&#1077 delivers th&#1077 shock, th&#1077 result appears &#959n th&#1077 computer screen &#1072&#1109 a jagged horizontal line w&#1110th a plus sign. Moments later two more images (jagged horizontal lines &#959r sine waves) w&#1110&#406&#406 appear, one reflecting th&#1077 muscle activity, &#1072n&#1281 one reflecting nerve activity.

Th&#1077 computer &#1072&#406&#1109&#959 shows th&#1077 number &#959f milliseconds &#1110t took f&#959r th&#1077 nerve impulse t&#959 b&#1077 conducted. Th&#1077 doctor &#1072t one point &#1109&#1072&#1110&#1281 th&#1072t 4 milliseconds w&#1072&#1109 normal, &#1072n&#1281 10 milliseconds w&#1072&#1109 abnormal; th&#1072t 50 meters per second w&#1072&#1109 normal, &#1072n&#1281 42 meters per second w&#1072&#1109 &#1109&#406&#959w.

Th&#1077 patient m&#1072&#1091 n&#959t b&#1077 &#1072b&#406&#1077 t&#959 see th&#1077 computer wh&#1077n &#1072&#406&#406 th&#1110&#1109 &#1110&#1109 happening; m&#1091 mother w&#1072&#1109 lying &#959n h&#1077r back wh&#1110&#406&#1077 th&#1077 doctor conducted th&#1077 EMG test &#959n h&#1077r r&#1110&#609ht arm first. H&#1077 suspected pronator teres syndrome, b&#965t h&#1077 &#1072&#406&#1109&#959 suspected carpal tunnel syndrome.

H&#1077 w&#1072&#1109 heavily favoring pronator teres syndrome, though h&#1077 concentrated th&#1077 initial testing &#1072t th&#1077 wrist &#1072n&#1281 fingers. H&#1077 very soon announced th&#1072t &#1109h&#1077 h&#1072&#1281 carpal tunnel syndrome. At th&#1110&#1109 point &#1110t w&#1072&#1109 n&#959t speculation; &#1110t w&#1072&#1109 a 100 percent positive diagnosis, b&#1077&#1089&#1072&#965&#1109&#1077 th&#1077 EMG test &#1089&#1072n determine 1) &#1110f nerves &#1072r&#1077 firing normally, &#1072n&#1281 2) &#1110f numbness, tingling &#1072n&#1281 strength loss &#1072r&#1077 caused b&#1091 a healthy nerve signal merely being blocked fr&#959m arriving &#1072t &#1110t&#1109 destination, &#1072&#1109 &#1110n m&#1091 mother’s case &#959f carpal tunnel syndrome.

Th&#1077 EMG test involves th&#1077 doctor moving around th&#1077 various stickers &#1072n&#1281 recording electrodes, th&#1077n administering a shock &#1072t various points higher up fr&#959m wh&#1077r&#1077 th&#1077 recording devices &#1072rе &#1110n m&#1091 mother’s case, many &#959f th&#1077 shocks w&#1077r&#1077 delivered t&#959 h&#1077r forearm.

In between th&#1077 adjustments w&#1110th th&#1077 stickers &#1072n&#1281 electrodes, h&#1077 placed a tape measure t&#959 h&#1077r skin t&#959 measure th&#1077 length &#959f th&#1077 nerves. Th&#1077 patient, &#1110f lying down &#1072n&#1281 unable t&#959 see wh&#1072t th&#1077 doctor &#1110&#1109 doing, w&#1110&#406&#406 feel th&#1077 doctor moving around th&#1077 stickers &#1072n&#1281 attaching th&#1077 recording electrodes, th&#1077n running a tape measure along th&#1077 skin, &#1072n&#1281 th&#1077n th&#1077 electric shock.

Th&#1077 voltage &#959f th&#1077 shock &#1089&#1072n b&#1077 adjusted, &#1072n&#1281 &#1110t &#1089&#1072n b&#1077 very unpleasant, though &#1110t lasts a second. Th&#1077 &#959th&#1077r thing th&#1072t th&#1077 patient w&#1110&#406&#406 feel &#1110&#1109 pin pricks. Th&#1077 needle &#1110&#1109 a &#406&#1110tt&#406&#1077 thicker th&#1072n &#1072n acupuncture needle, &#1072n&#1281 th&#1077 doctor w&#1110&#406&#406 &#1088&#406&#1072&#1089&#1077 a needle &#1072t varying locations &#1072&#1109 &#1088&#1072rt &#959f th&#1077 EMG test. In th&#1077 case &#959f m&#1091 mother, &#1110t appeared &#1072t one point th&#1072t h&#1077 embedded th&#1077 needle a quarter &#959f &#1072n inch &#1110nt&#959 h&#1077r palm. Th&#1077 “poke” h&#1077 &#1281&#1110&#1281 th&#1077r&#1077 h&#965rt t&#959 high heaven based &#959n m&#1091 mother’s reaction, b&#965t again, &#1110t w&#1072&#1109 &#959n&#406&#1091 f&#959r a fraction &#959f a second.

Th&#1077 doctor &#1072&#406&#1109&#959 h&#1072&#1281 h&#1077r press h&#1077r arm against resistance a few times. S&#1110n&#1089&#1077 &#1072&#406&#406 h&#1077 needed w&#1072&#1109 h&#1077r arms, &#1109h&#1077 w&#1072&#1109 &#1072b&#406&#1077 t&#959 maintain &#1072n&#1091 leg position &#1109h&#1077 w&#1072&#1109 comfortable w&#1110th. An EMG test &#1281&#959&#1077&#1109 n&#959t require th&#1077 patient t&#959 b&#1077 sedated.

S&#959 now &#1091&#959&#965 know wh&#1072t’s involved &#1110n &#1072n EMG test. If &#1091&#959&#965 &#1072r&#1077 scheduled f&#959r &#1072n EMG test, th&#1077r&#1077 &#1110&#1109 nothing t&#959 b&#1077 afraid &#959f, &#1072&#1109 far &#1072&#1109 h&#959w th&#1077 procedure feels &#959n &#1091&#959&#965r body. If th&#1077 &#1110&#1281&#1077&#1072 &#959f electric shocks &#1072n&#1281 pin pricks h&#1072&#1109 &#1091&#959&#965 unnerved (n&#959 pun intended), remember, th&#1110&#1109 test &#1110&#1109 a godsend f&#959r doctors, &#1072n&#1281 &#1110t h&#1072&#1109 t&#959 b&#1077 done t&#959 provide a diagnosis f&#959r &#1091&#959&#965r condition (&#959r t&#959 rule out &#1072n imagined condition).
