EMG's work on the same principle as an electrical wire and voltage transmission/measurement. Two probes are inserted, one at the top of the arm or the upper end of the nerve, the other one near the wrist before it goes past the wrist bone and into the pinky.
The upper probe is usually the transmission probe, the other the receiving. Since a specific, measurable amount of voltage is used, the voltage drop between probes can be measured and compared with established norms. Depending on the voltage drop between the probes, it will show how much actual nerve damage there is, or isn't. The reason no nerve damage is showing on the test is that there isn't enough voltage drop suggesting any real damage. If it were damaged, the drop would be measurable and comparable to established parameters. While it may have been slight, it obviously wasn't bad enough to be measurable.
Keep in mind that just because you have ulnar nerve pain doesn't mean it's damaged - in fact, if you have pain it means it's working well and something is compressing it elsewhere. For "elsewhere" I'd consider whether or not you've had any neck injuries, as arm nerves originate in the cervical spinal area. My own ulnar nerve constantly hurts due to injuries at the elbow, and major spinal damage in the neck which left permanent nerve damage.

How much damage did the holocaust cause?
There is no real way of estimating that. Where the line between war damage and damage due to the Holocaust is would be hard to tell. There have been numerous attempts to estimate how much wealth was stolen in the Holocaust, but there are problems with that also. The greatest damage was of course the human damage, the six million murder victims and the may hundred thousand survivors many of who never recovered.
What would be the blast radius of a 200 megaton nuclear bomb?
Well i did some rough estimates...prob be like 56 milesA blast radius is equal to the square root of the megatonage. A 1 megaton bomb has a blast radius of severe damage of about 4 miles. Therefore a 200 megaton bomb (14 being about the square root) would have about a 56 mile radius. Though direct exposure to the explosion at that distance could probably still cause severe burns and it would probably cause damage as much as 200 miles out.
What whips did they use on the first fleet?
The most common whip was the cat o'nine tails. This type of whip had nine leather or corded strands, each with a knot at the end which would cause extra damage to the skin.
Why were zeppelins so hard to shoot down?
They were hard to shoot down because of their enormous size. If you went up in a plane and tried to shoot one down with a normal bullet it would create a leak, but not one big enough to cause any sever damage.
What if the WTC towers did not collapse?
If the WTC towers did not collapse, they would eventually be due to the extensive damage beyond repair
How do you relieve a trapped nerve?
The answer truly depends on the severity of the ulnar entrapment and the location of the ulnar nerve entrapment. Milder ulnar nerve entrapments can sometimes be relieved with physical therapy and bracing the arm in a position that lessens pressure on the ulnar nerve. Moderate entrapments of the ulnar nerve may respond to physical therapy combined with a steroid injection to relieve inflammation. More severe entrapments may require surgical interventions. The most common location for an ulnar nerve entrapment is at the elbow, this is called an ulnar neuropathy at the elbow (UNE). When this is severe the surgical procedure that is utilized is referred to as a surgical transposition of the ulnar nerve & involves moving the ulnar nerve from the back of the elbow to the front of the elbow. Speak with a neuromuscular specialist regarding your case if you feel that you have an ulnar entrapment, and always keep in mind that you may want to get a second opinion. Be prepared for the possibility of an electrodiagnostic examination. This test would help determine if ulnar nerve is involved, where along the ulnar nerve the lesion is, & how severe the ulnar nerve lesion is.
Would an mild electric shock cause nerve damage?
Yes it would cause a nerve damage but it depends on where and how long you give mild electric shock to somebody. i think so?
Can vagus nerve damage cause seizures?
Yes, it can as the vagus nerve relays the parasympathetic inhibition of the heart rate.
What would cause your upper lip to pulsate?
facial injury, nerve damage,vitamin deficiency
What is the nerve in the medial epicondyle that makes your hand tingle?
i believe this is the ulnar nerve. when this nerve gets a bang it creates the sensation that one would experience when they, "bang their funny bone".
What causes no feeling in your right fingers?
A stroke or nerve damage would cause a lack of sensation in the fingers.
What happens if the ulnar nerve injury was damaged after ctr surgery?
That would depend on the extent of the damage, I had a complete elbow replacement done which included an ulnar nerve decompression. According to the surgeons that worked on me, I would experience tingling and some numbness on the little finger up one side of the ring finger and on the hand over those two fingers for about 18 months however after 6 months everything seems to have settled down nicely.
Should you have surgery for left ulnar neuropathy?
It depends on the cause of the ulnar neuropathy. Anconeus epitrochlearis, a accessory muscle slip which can cause this syndrome would be addressed surgically, as would a nerve sheath tumor. Many other causes would not require surgery.
Ulnar nerve damage?
I'm not sure what you are asking about ulnar nerve damage, but here is some basic information. I know more about this nerve than others because I personally experienced problems with it. Your ulnar nerve starts in your shoulderblade area and runs down the side of your arm to the outside of your hand and outside two fingers. When this nerve is affected, you feel differences in senses along these sights. In my case, my shoulder had been essentially hanging in my socket for months (the ligaments had all been stretched beyond capacity) and the result was swelling of my bursa sack, putting pressure on this nerve. I experienced very painful tremors down my arm, occasionally lost feeling in my outer fingers, and sometimes dropped things because my fingers would not respond correctly. However, after steroid shots (which reduce swelling) these symptoms improved (but did not disappear). After corrective surgery, the feeling slowly came back and now I have almost full function in these outer fingers (1+ years later). So, one can experience both pressure on the nerve (which has similar but not permanent affects to damage) and one can have damage. With either one you will have similar effects (the nerve is pressured so firing is sporadic, intermittent, and not functional) but with damage the problems will not go up and down in severity. It will be steady. If you suspect either, go to a doctor. If you just wanted to know the symptoms, there you go. p.s. don't mess with nerve damage--unless you want permanent problems
How high must the pressure be in a person's eye in order to cause damage to the optic nerve?
A higher pressure for a long period of time will gradually start to cause damage to the optic nerve. My guess would be mid 20's and higher, but you can always ask your doctor too.
What would happen if the ventral root of a spinal nerve were damage or transected?
There are a number of things that would happen if the ventral root of a spinal nerve were damage or transected, This would mainly cause the loss of the sensory function and there would be neuropathic pain among other effects.
Is a neurotoxin an endotoxin?
Neurotoxins damage nerve cells. I believe that an endotoxin can be a neurotoxin, but a neurotoxin is not necessarily an endotoxin. Kinda like lead is a neurotoxin but a neurotoxin is not necessarily lead. An excitoxin is neurotoxin since exitotoxins damage nerve and glial cells. Endotoxins and exotoxins have to do with bacteria and if they cause nerve damage they would be considered neurotoxins.
