Neuromuscular Assessment in Henderson

Weakness and numbness can arise at four different levels with unrelated treatments. Localising which, and grading how severe, is what changes the decision rather than what names it.

Quick Answer

Neuromuscular assessment localises weakness or numbness to a nerve root, a specific peripheral nerve, the neuromuscular junction or the muscle, and grades how severe the finding is. Performed and interpreted at 1691 W. Horizon Ridge Parkway, Suite 100, Henderson NV 89012 in an independently accredited laboratory.

Key Takeaways

Electrodiagnostic study in progress at an accredited laboratory
  • Weakness or numbness can arise at four levels: root, nerve, junction or muscle, with unrelated treatments.
  • Examination narrows the level; an electrodiagnostic study localises it and grades severity.
  • Grading determines whether splinting and activity modification are appropriate or whether decompression should be considered sooner.
  • Performed and interpreted at 1691 W. Horizon Ridge Parkway, Suite 100, Henderson NV 89012, in a laboratory holding AANEM accreditation in its own right.
  • A normal standard study does not exclude a small-fibre process causing burning pain.

Electromyography

Electromyography and nerve conduction studies are electrodiagnostic tests that measure how well nerves conduct signals and how muscles respond. Together they show whether nerve or muscle damage is present, where it is, and how severe.

What a neuromuscular assessment establishes

Neuromuscular medicine concerns the peripheral nerves, the junction between nerve and muscle, and the muscles themselves, rather than the brain and spinal cord. It is the area where the diagnostic study carries the most weight.

Localisation is the whole task

Weakness, numbness or wasting can arise at four different levels, and the treatments are unrelated. A nerve root compressed in the neck or back. A specific peripheral nerve entrapped at a known site. The junction between nerve and muscle, as in myasthenia gravis. Or the muscle itself. Examination narrows it; an electrodiagnostic study localises it and grades how severe it is. Those are different outputs and the second is what changes decisions.

Why grading matters as much as the finding

Mild nerve compression with preserved nerve fibre function frequently responds to activity modification and splinting. Significant slowing with measurable fibre loss shifts the conversation toward decompression sooner, because prolonged compression at that level risks permanent change. Those two patients look similar in clinic, and only a graded study separates them, which is why a report that names a finding without grading it has left the useful part undone.

What the study cannot do

Standard nerve conduction studies assess large nerve fibres. A small-fibre process causing burning pain can coexist with an entirely normal study, so a normal result does not mean nothing is wrong. Interpreting that correctly is part of the clinical assessment rather than the study, and it is a common source of confusion. The Muscular Dystrophy Association publishes patient material across the wider neuromuscular group.

How this practice handles it

01

What brings people in

A referral to find out whether nerve or muscle damage is present, or to confirm a suspected entrapment before surgery.

02

What the evaluation settles

Whether conduction is measurably abnormal, which nerves and roots are involved, the severity, and whether the process is focal or generalised.

03

What you leave with

A graded, quantified report interpreted by the neurologist who performed the study, in an AANEM-accredited laboratory.

Performed and interpreted by the same physician

An electrodiagnostic study is planned as it proceeds. An early finding frequently indicates which additional nerve or muscle to examine, and that judgement requires understanding the clinical question. Where a technician follows a fixed protocol and a physician reads the output later, that adaptive step is lost and an ambiguous result becomes a repeat appointment rather than an answer obtained the same day.

Accredited laboratories at both offices

Both electrodiagnostic laboratories hold accreditation from the AANEM independently rather than one operating under the other, and the practice was the first physician-owned outpatient EDX laboratory in Nevada to reach exemplary status. Accreditation is voluntary peer review of actual reports rather than a self-assessment, which is what makes it meaningful. What it covers and does not cover is on the accreditation page.

Two of the neurologists focus on neuromuscular medicine

Including one whose focus includes neuromuscular ultrasound, which images nerve and muscle structure and complements rather than replaces functional testing. The team is on the providers page. Adults 18 and older, at both offices on the locations page.

The first 30, 60 and 90 days

Step 1

First visit

History and neurological examination, a review of records and prior imaging, and a decision on which studies are actually indicated. You leave with the plan, not just a referral.

Step 2

Within 30 days

Indicated in-office studies are performed and interpreted by the neurologist who ordered them, in our AANEM-accredited laboratories. Results are explained in plain language.

Step 3

60 to 90 days

Follow-up to judge whether the plan is working, adjust it, and coordinate with your referring clinician. Where a diagnosis needs time to confirm, this is where it is revisited.

Attending from Henderson

The Henderson office is at 1691 W. Horizon Ridge Parkway, Suite 100, just off the 215 Beltway, with parking on site. All six in-office studies are performed and interpreted there, so nothing is sent across to Las Vegas. Green Valley, Anthem, Whitney and Boulder City are generally closer to it than to Flamingo Road. Adults 18 and older.

Referred for nerve or muscle testing?

No sedation, no fasting, no driver. Ask for the study to be graded rather than only named.

The Bottom Line

Ask for the study to be graded rather than only named, because severity rather than the finding is what determines the decision.

Frequently Asked Questions

What does a neuromuscular specialist assess?

The peripheral nerves, the junction between nerve and muscle, and the muscles themselves, rather than the brain and spinal cord. Weakness or numbness can arise at four different levels with unrelated treatments, and localising which is the task. Getting the level right is what stops treatment being aimed at the wrong structure.

Why does grading matter, not just the finding?

Because mild compression with preserved nerve function often responds to activity modification and splinting, while significant slowing with fibre loss shifts the conversation toward decompression sooner. Those patients look similar in clinic and only a graded study separates them. The grade, rather than the label, is what a surgeon needs in order to advise you.

Why does the same physician perform and interpret the study?

Because the study is planned as it proceeds. An early finding indicates which additional nerve or muscle to examine, and that judgement requires understanding the clinical question. A fixed technician protocol loses that adaptive step. It also means your questions can be answered while you are still in the room rather than weeks later.

My nerve study was normal but symptoms continue. What does that mean?

Standard studies assess large nerve fibres. A small-fibre process causing burning pain can coexist with an entirely normal study, so a normal result does not exclude a problem. Recognising that pattern clinically is what fills the gap. Skin biopsy and autonomic testing are the usual next steps and are coordinated externally.

Is the laboratory accredited?

Both electrodiagnostic laboratories hold AANEM accreditation independently rather than one operating under the other, and the practice was the first physician-owned outpatient EDX laboratory in Nevada to reach exemplary status. Accreditation covers technique, equipment calibration, reporting standards and physician qualifications, so it describes how the study is actually run rather than being simply a badge on the door.

Where exactly is the Henderson office?

1691 W. Horizon Ridge Parkway, Suite 100, Henderson NV 89012, just off the 215 Beltway, with parking on site. All six in-office studies are performed and interpreted there, so nothing is referred across to the Las Vegas office. Green Valley, Anthem, Whitney and Boulder City are generally closer to it than to West Flamingo Road.

Should I use the Henderson or the Las Vegas office?

Whichever is the shorter drive, since both are fully equipped and hold the same records. West Horizon Ridge Parkway generally suits Green Valley, Anthem and Boulder City; West Flamingo Road suits the west and southwest of the valley. If you can attend either, say so when booking, because availability differs between the two week to week.

Can I have the study without a consultation first?

It is generally better after one, because the examination determines which nerves and muscles the question actually requires. A study planned from a referral line alone risks measuring the wrong thing well. Where a referring clinician has already localised the problem, the two can sometimes be combined into one visit.

What makes a report useful later?

Actual measurements rather than a conclusion alone, compared against reference values appropriate to your age and height, with the nerves and muscles examined named. A report saying a study was normal cannot be compared against a later one; the underlying numbers can. Ask for a copy for your own records.

What should I wear or bring?

Clothing that allows easy access to the arms and legs, or expect to change. No fasting and no sedation, so eat normally, take your usual medications and drive yourself home. Avoid lotions and oils on the skin. Disclose blood thinners, a bleeding disorder, or an implanted cardiac or neurostimulation device beforehand.
