NCV / EMG Studies

Objective nerve conduction and electromyography testing — precise, quantifiable evidence of nerve damage for injury documentation.

🌀

Vestibular Therapy

Specialized rehabilitation for dizziness, balance disorders, and inner ear dysfunction frequently caused by head trauma and whiplash.

🔬

Neurological Evaluations

Board-certified neurologist examinations providing comprehensive assessment, diagnosis, and medico-legal documentation for injury cases.

Why Early Testing Matters

Most Neurological Injuries Are
Missed After an Accident

80%
Of Mild TBIs Go Undiagnosed
Standard ER CT/MRI evaluations miss the majority of concussions and mild traumatic brain injuries.

TBI Cases Per Year in the U.S.
TBI is the most common — and most underdiagnosed — consequence of motor vehicle accidents.

Dizziness and balance disorders after an accident are frequently missed without specialized testing.
🧠
Normal CT ≠ No Brain Injury
QEEG and EEG detect functional brain abnormalities that CT and MRI cannot — providing objective evidence.

Personal Injury

Neurological Care After an Accident

Comprehensive neurological evaluation and legal documentation for personal injury victims across Arizona.

Why It Matters

Injuries That Aren't Always Visible

After a car accident, slip and fall, or workplace injury, neurological damage can be present even when standard imaging appears normal. QEEG and EEG detect functional brain abnormalities that CT and MRI cannot see.

  • QEEG & EEG to detect post-traumatic brain abnormalities
  • NCV/EMG for objective nerve damage quantification
  • Vestibular evaluation for dizziness and balance issues
  • Board-certified neurologist on every case
  • Detailed reports suitable for legal proceedings
  • Home visits — no car? no problem
  • Medical lien accepted — no upfront cost
🚗

Auto Accident Injuries

Whiplash, head impact, and deceleration forces cause TBI and nerve damage. Full neurological workups for MVA victims.

🏗️

Workplace & Slip/Fall

Falls and workplace accidents cause head trauma and spinal nerve injury. Objective diagnostics for injury documentation.

⚖️

Medico-Legal Reports

Court-ready reports with causation analysis from board-certified physicians available for expert testimony.

The Problem

Why TBIs Go Undiagnosed

Standard CT and MRI often appear normal after mild-to-moderate TBI — yet patients suffer real, measurable neurological damage. QEEG and EEG detect functional brain abnormalities invisible to structural imaging.

"Up to 80% of concussions and mild TBIs are missed in emergency evaluations relying solely on standard imaging." — Brain Injury Association of America

Common Symptoms

  • Persistent headaches or migraines
  • Dizziness, vertigo, or balance problems
  • Memory loss or difficulty concentrating
  • Sensitivity to light and noise
  • Mood changes, irritability, or depression
  • Numbness, tingling, or weakness in extremities

Why QEEG/EEG

Detects functional brain abnormalities and post-traumatic changes invisible to MRI/CT.

🔬

Why NCV/EMG

Objectively quantifies peripheral nerve damage — undeniable data.

🌀

Why Vestibular

Up to 40% of TBI patients have vestibular dysfunction — frequently missed.
