Is the spine moving in an expected way?
ADVANCED SPINE EVALUATION
Advanced Spine & Biomechanical Evaluation
When an Injury Requires a Closer Look at Spinal Motion, Stability, and Function
WHEN MORE DETAIL MAY HELP
When Might a More Detailed Evaluation Help?
Most spine problems do not require advanced biomechanical analysis.
A more detailed assessment may be considered when a spine problem is persistent, follows significant trauma, raises concern about abnormal motion or stability, or when the examination and existing imaging do not fully explain what is happening.
The purpose is not simply to collect more measurements. It is to determine whether additional information could help guide the next clinical decision.
ADVANCED BIOMECHANICAL ANALYSIS
What May Be Evaluated
When appropriate, specialized computerized biomechanical analysis may be used to quantify spinal motion and help evaluate whether abnormal movement patterns are clinically significant.
These measurements are interpreted in the context of the injury, physical examination, symptoms, function, and other imaging findings rather than being considered in isolation.
Spinal motion
Segmental relationships
Alignment
Abnormal translation or angular motion
Ligamentous integrity and instability considerations
Movement under physiologic loading
Relevant imaging findings
Clinical examination findings
Symptoms and functional limitations
CLINICAL QUESTIONS
What Are We Trying to Understand?
The measurements themselves are not the end goal. The goal is to answer clinical questions that may affect what happens next.
Are there findings suggesting abnormal motion between spinal segments?
Do the imaging findings fit the symptoms and examination?
Is there concern that motion, stability, or ligament function should influence treatment decisions?
Does the current treatment approach still make sense?
Would rehabilitation, additional imaging, referral, co-management, or another management strategy be more appropriate?
FROM MEASUREMENT TO MANAGEMENT
From Measurement to Management
The purpose of biomechanical analysis is not simply to identify an abnormal measurement. When a finding is clinically meaningful, it may influence how care is delivered and how recovery is monitored.
Depending on the clinical findings, advanced information may help guide decisions involving:
Whether conservative care remains appropriate
Whether spinal manipulation is appropriate
Whether technique or treatment approach should be modified
Areas requiring additional caution or protection
Rehabilitation priorities
Stabilization and motor-control goals
Activity and loading progression
Need for additional diagnostic evaluation
Reassessment strategy
Referral, co-management, or another level of care
Measure What Matters. Treat What Is Clinically Meaningful. Reassess as the Spine Recovers.
LIGAMENTS, MOTION & STABILITY
Ligamentous Injury & Abnormal Motion
Spinal ligaments contribute to stability by helping control motion between vertebral segments. Following trauma, significant ligament injury can alter normal motion even when a static image does not fully demonstrate the functional problem.
In selected cases, motion-based imaging and biomechanical measurement may provide additional information about how the spine behaves through movement. These findings are interpreted alongside the patient’s history, examination, symptoms, neurologic findings, function, and other imaging.
Ligament injury, laxity, abnormal segmental motion, radiographic instability, and clinically meaningful instability are related but not interchangeable.
Professional involvement in this area: Dr. Farmen’s professional education and speaking work includes an invitation to participate in a SpineCAMP 2026 panel discussion in Dallas addressing complex spinal ligament injuries.
IMPORTANT CLINICAL CONTEXT
Measurements Must Be Interpreted in Context
Dynamic motion alone does not prove injured tissue or traumatic causation in an individual patient.
Biomechanical measurements and imaging findings are considered alongside the injury history, symptoms, examination findings, neurologic findings when relevant, function, other imaging, and the overall clinical picture.
No single measurement or image should be treated as the entire diagnosis.

START WITH AN EVALUATION
Not Sure Whether You Need an Advanced Evaluation?
Most patients do not need advanced biomechanical testing.
Start with an evaluation. If a more detailed assessment of spinal motion, stability, imaging, or biomechanics is appropriate, we can explain why it may be useful and what clinical question we are trying to answer.
