Back Pain Diagnosis in Scarborough: How Advanced Neurological and Orthopedic Exams Find the Real Cause
If you’ve been dealing with persistent neck or back pain, you’ve probably heard the same advice over and over:
“Get an MRI.”
“Get an X-ray.”
While imaging can be useful, many people are surprised to learn that the most important diagnostic tool is often a detailed physical examination.
At Atlas Spine Clinic, we use advanced neurological and orthopedic examinations to identify the true source of pain before recommending imaging or treatment.
Because imaging alone often answers what looks different in the spine — not what is actually causing your symptoms.
This guide explains how modern clinical examinations diagnose the root cause of back, neck, and nerve-related pain.
Why Physical Examination Comes Before Imaging
An MRI can show structural changes such as:
- Disc bulges
- Degeneration
- Arthritis
- Spinal narrowing
But these findings are extremely common — even in people with no pain at all.
Clinical research consistently shows that many adults have disc bulges or degenerative changes on MRI without experiencing symptoms.
That’s why diagnosis must begin with:
- Patient history
- Neurological testing
- Orthopedic examination
- Movement assessment
Only after these steps does imaging become truly useful.
This approach allows clinicians to understand why pain occurs, not just what appears on a scan.
The Neurological Examination: Testing the Nervous System
Your nervous system functions like an electrical network connecting the brain to the body.
When a spinal nerve becomes irritated or compressed, symptoms may include:
- Radiating pain
- Numbness
- Tingling
- Muscle weakness
A neurological examination helps determine which nerve may be involved.
Dermatomes: Testing Skin Sensation
Each spinal nerve provides sensation to a specific region of skin called a dermatome.
By testing sensation with light touch or gentle pressure across these areas, clinicians can identify patterns of altered sensation that correspond to specific nerve roots.
For example:
- Thumb numbness may indicate C6 nerve involvement
- Outer leg symptoms may indicate L5 nerve involvement
This mapping helps pinpoint the exact level of spinal dysfunction.
Myotomes: Testing Muscle Strength
Each spinal nerve also controls certain muscle groups.
Clinicians perform resisted muscle tests to evaluate nerve function.
Examples include:
- Shoulder abduction strength
- Wrist extension
- Big toe lifting
- Foot plantar flexion
Weakness in a specific movement can reveal which spinal nerve root may be compromised.
Reflex Testing
Reflex testing evaluates the communication pathway between the spinal cord and muscles.
Common reflex tests include:
- Biceps reflex
- Triceps reflex
- Patellar (knee) reflex
- Achilles reflex
Abnormal reflex responses may indicate nerve irritation or neurological dysfunction.
Orthopedic Special Tests: Reproducing the Pain Source
Orthopedic tests place controlled stress on specific tissues to confirm the cause of symptoms.
These tests help determine whether pain originates from:
- Discs
- Joints
- Muscles
- Ligaments
- Nerves
Cervical Spine Tests (Neck Pain)
One commonly used test is Spurling’s Test.
During this exam, the head is gently tilted and compressed to see whether arm pain or tingling appears.
If symptoms reproduce, it suggests cervical nerve root compression.
Another test, cervical distraction, gently lifts the head. If symptoms decrease, it confirms nerve pressure as the likely cause.
Lumbar Spine Tests (Back Pain and Sciatica)
The Straight Leg Raise Test is commonly used to assess sciatica.
While lying down, the clinician raises the leg while keeping the knee straight.
If pain radiates down the leg between roughly 30° and 70°, it often indicates a lumbar disc irritation affecting a nerve root.
Another highly sensitive assessment is the Slump Test, which evaluates nerve tension throughout the spinal cord and sciatic nerve.
Palpation and Movement Assessment
Imaging cannot detect everything.
Hands-on assessment provides essential information about:
- Joint mobility
- Muscle tension
- Spinal alignment
- Tissue inflammation
Clinicians use palpation to identify restricted spinal segments, muscle guarding, or asymmetrical movement patterns.
These findings often reveal the mechanical cause of pain.
Assessing Nerve Mobility
Nerves must glide and move freely as the body moves.
When surrounding tissues restrict nerve motion, it creates adverse neural tension, which can cause:
- Sciatica
- Arm pain
- Tingling sensations
Through controlled movements, clinicians evaluate whether symptoms change when nerve tension increases or decreases.
If so, treatments that improve nerve mobility — such as nerve glide exercises — can significantly reduce pain.
Putting the Diagnosis Together
A single test rarely provides the answer.
A skilled clinician combines findings from:
- Patient history
- Neurological testing
- Orthopedic examination
- Movement assessment
- Palpation findings
This comprehensive approach leads to precise diagnoses such as:
- Lumbar disc irritation affecting the L5 nerve root
- Cervical radiculopathy
- Facet joint dysfunction
- Sciatic nerve tension
Once the source of pain is clear, treatment can be targeted effectively.
Frequently Asked Questions
Why not get an MRI first?
Because imaging alone does not identify the functional cause of pain. A physical examination ensures imaging is interpreted correctly.
Can these tests diagnose sciatica?
Yes. Neurological and orthopedic exams are the primary way clinicians diagnose nerve-related pain such as sciatica.
Can I perform these tests at home?
No. These tests require precise positioning and professional interpretation to avoid aggravating symptoms.
Can a chiropractor diagnose spine conditions?
Yes. Chiropractors are trained to perform neurological and orthopedic examinations to diagnose musculoskeletal and nerve-related conditions.
