EMG
Electromyography (EMG) is a method for testing the electrical activity of the muscles. This technique is performed using a procedure called electromyography. EMG may help with the diagnosis of nerve root injury or nerve compression injury.
73 Questions
What does a normal emg look like?
A normal electromyography (EMG) shows consistent electrical activity in muscles at rest, typically characterized by a flat line or minimal spontaneous activity. During voluntary contraction, the EMG displays well-defined, orderly waveforms with consistent amplitude and frequency, reflecting healthy muscle recruitment. There should be no signs of abnormal electrical activity, such as fibrillation potentials or positive sharp waves, which could indicate muscle or nerve damage. Overall, a normal EMG indicates proper neuromuscular function.
What is the placement of electrodes for male electroplay?
For male electroplay, electrodes are typically placed on the penis, scrotum, and perineum to enhance stimulation. Additional placements can include the thighs and lower abdomen for broader sensations. It's important to ensure the electrodes are securely attached and that the settings are adjusted gradually to maintain comfort and safety. Always prioritize consent and communication with the partner during the experience.
Is severe pain during emg and nerve conduction study common?
Severe pain during an electromyography (EMG) and nerve conduction study is not common, but some discomfort is expected due to the nature of the tests. Patients may experience mild to moderate pain from the needle insertions during the EMG or a tingling sensation during nerve conduction studies. However, if a patient experiences severe pain, they should inform the technician or physician, as adjustments can often be made to improve comfort. Overall, while some discomfort is normal, severe pain should not be a typical experience.
What does no response mean in an EMG test?
"No Response," or NR, generally occurs during the nerve conduction portion of an electrodiagnsotic examination (often called an EMG). When performing a nerve conduction study an electrical impulse is transmitted through a nerve and recorded at a point distant to that point of stimulation. Normally when this impulse is recorded as a waveform that is produced on the screen for the electromyographer to evaluate. An NR occurs when a waveform cannot be elicited with an electrical impulse. This finding suggests that the nerve being tested has suffered loss of function of some or all of its axons. This does not mean that the nerve being studied is completely dead, but it does suggest significant loss of function in that particular nerve. This "NR" finding may also may be the result of a technical error on the part of the electromyographer.
What is the cost of a leg EMG?
Electrodiagnostic testing that includes NCS & EMG can be very expensive, with prices ranging from $800-$2500. This type of testing can be very sensitive and useful to determining if there is a problem with a nerve, and if there is a problem, it can determine how bad that problem is.
What is the artificial device used to regulate the heart rhythm by delivering electrical impulses?
A pacemaker
Can you take hydrocodone before a EMG test?
Yes,you can but you shouldnt because pain killers will effect the nerve responses and make for inaccurate results. so just have your test and take your medicine after. If you have nerve damage youll need it more after the test anyhow.
Electromyography, a method of evaluating muscle function by detecting and measuring electrical activity in the muscle.
EMG is a method of measuring muscle activity. In a research laboratory where conditions can be controlled (such as location of electrodes, posture of subject, etc.) and the data can be analyzed accurately (normalized, etc) this can be a very useful tool. A small number of chiropractors feel that this tool can be used to detect areas of spastic or "tense" musculature, and thereby use it to help decide where to adjust the spine. The problem is that none of the strict controls or data analyzing techniques are applied in the clinical setting (doctors office), making this tool very inaccurate. Further, there have not been any studies done that examine the clinical relevance of this tool (no link has been shown between good "scans" and better health of a patient).
As a rule the more areas you need studied, the more the test will cost. However costs may vary from one physician to another and is different in different states. It is always best to inquire about cost with your physician. Most insurance policies cover EMGs, though frequently the coverage is not 100% and the primary care or insurance physician will have to OK it before it can be ordered. It is best to have your doctor's office find out what kind of coverage you have for an EMG.
Yes they are.

Morton's neuroma is a thickening of nerve tissue between the toes. It commonly affects the nerve that travels between the third and fourth toes.
See also: Foot pain
Causes, incidence, and risk factorsMorton's neuroma is more common in women than men.
The exact cause is unknown. However, some experts believe the following may play a role in the development of this condition:
- Abnormal positioning of toes
- Flat feet
- Forefoot problems, including bunions and hammer toes
- High foot arches
- Tight shoes and high heels
Symptoms of Morton's neuroma include:
- Tingling in the space between the third and fourth toes
- Toe cramping
- Sharp, shooting, or burning pains in the ball of your foot (and sometimes toes)
- Pain that increases when wearing shoes or pressing on the area
- Pain that gets worse over time
In rare cases, nerve pain occurs in the space between the second and third toes. This is not a common form of Morton's neuroma, but treatment is similar.
Signs and testsA foot x-ray may be done to rule out bone problems. MRI or high-resolution ultrasound can successfully diagnose Morton's neuroma.
Nerve testing (electromyography) cannot definitely diagnose Morton's neuroma, but may be used to rule out conditions that cause similar symptoms.
Your doctor may order blood tests to check for inflammation-related conditions, including certain forms of arthritis.
TreatmentNonsurgical treatment is tried first. Your doctor may recommend any of the following:
- Padding and taping the toe area
- Shoe inserts
- Changes to footwear (for example, shoes with wider toe boxes)
- Anti-inflammatory medicines taken by mouth or injected into the toe area
- Nerve blocking medicines injected into the toe area
- Other painkillers
- Physical therapy
Anti-inflammatories and painkillers are not recommended for long-term treatment.
In some cases, surgery may be needed to remove the thickened tissue. This can help relieve pain and improve foot function. Numbness after surgery is permanent, but should not be painful.
Expectations (prognosis)Nonsurgical treatment does not always improve symptoms. Surgery to remove the thickened tissue is successful in about 85% of cases.
ComplicationsMorton's neuroma can make walking difficult. Persons with this foot condition may also have trouble performing activities that put pressure on the foot, such as pressing the gas pedal of an automobile. It may hurt to wear certain types of shoes, such as high-heels.
Calling your health care providerCall your health care provider if you have persistent pain or tingling in your foot or toe area.
PreventionAvoid ill-fitting shoes. Wear shoes with a wide toe box.
