What Is the Selective Functional Movement Assessment?
The Selective Functional Movement Assessment (SFMA) is a clinical model that evaluates movement patterns in people with musculoskeletal pain (peer-reviewed research). Rather than asking where it hurts, it starts with how you move, then traces dysfunctional patterns to their root cause. At Spinal Haven, we use it because it reveals why a joint, muscle, or nerve compensates in ways that create pain.
Most people arrive with a label like "low back pain", a symptom, not the source. The SFMA breaks down full-body movements to isolate whether the problem stems from joint mobility, muscle length, motor control, or stability.
The goal is straightforward: restore pain-free movement so you can return to the activities you enjoy.
A Movement-Based Diagnostic System vs. Symptom-Based Diagnosis
Traditional orthopedic evaluation centers on a specific complaint, a painful shoulder, a stiff neck, an aching knee, and arrives at a tissue-based diagnosis. This works well for acute injuries but frequently misses the cause of chronic, recurring pain.
Your body operates as a kinematic chain: a limitation in ankle mobility can alter gait and eventually produce knee or low back pain. The SFMA identifies these compensatory patterns by breaking down fundamental movements and testing each component.
This is why patients who have "failed" traditional therapy often find answers here: if treatment focused only on the painful area without addressing the movement dysfunction driving it, the pain will keep returning.
The 7 Fundamental Movement Patterns in the SFMA
The SFMA evaluates seven fundamental movement patterns that represent the building blocks of human motion (peer-reviewed research). Each requires coordinated joint mobility, stability, and neuromuscular control to execute pain-free.
The seven patterns are:
- Cervical flexion (looking down)
- Cervical extension (looking up)
- Cervical rotation (turning the head)
- Upper extremity movement (reaching pattern)
- Multi-segmental flexion (bending forward)
- Multi-segmental extension (bending backward)
- Single-leg stance (standing on one leg)
These are top-tier tests designed to expose how your nervous system organizes movement across multiple joints. Multi-segmental flexion, for example, requires the lumbar spine to flex, the hips to hinge, and the hamstrings to lengthen in sequence.
How Each Pattern Is Scored
Each pattern is scored across two axes: functional vs. dysfunctional and painful vs. non-painful (peer-reviewed research). This creates a four-quadrant classification that drives all subsequent clinical reasoning:
- Functional and non-painful: Normal movement. No intervention needed for this pattern.
- Functional but painful: The movement is achievable, but tissue sensitivity exists. This often points to a loading problem or inflammatory component that needs direct management.
- Dysfunctional and non-painful: The movement is restricted or compensated, but no pain is provoked. This is the most clinically important category because it reveals the cause of pain elsewhere in the chain. A non-painful restriction in ankle dorsiflexion, for instance, may be loading the knee or low back abnormally during squats or walking.
- Dysfunctional and painful: Both a movement impairment and tissue sensitivity are present. The clinician must determine whether the pain is driving the dysfunction or the dysfunction is driving the pain, this distinction shapes the entire treatment order.
The Top-Tier to Breakout Progression
Once a pattern is scored as dysfunctional, the SFMA protocol requires a breakout, a systematic breakdown of the movement into its component parts. If multi-segmental flexion is dysfunctional and non-painful, the clinician will test:
- Joint mobility at the hips and lumbar spine (passive range of motion)
- Muscle length of the hamstrings, hip flexors, and thoracolumbar fascia
- Motor control during the active movement
- Stability of the core and pelvic floor during the hinge
This breakout answers why the pattern is broken, not just that it is broken. A limitation during passive testing suggests a mobility restriction; one that only appears during active movement suggests a motor control deficit.
Why the Order of Testing Matters
The SFMA is performed in a specific sequence, starting with the most global patterns and progressing to more isolated tests, preventing the clinician from being misled by a local finding that is actually a compensation for a problem elsewhere.
A common pattern is a patient with chronic low back pain who demonstrates a dysfunctional multi-segmental extension pattern. The breakout reveals tight hip flexors and weak gluteal activation. The clinician treats the hip flexor mobility first, then retrains gluteal motor control. The back pain resolves because the movement chain was restored, not because the back was treated directly.
SFMA vs FMS: What Is the Difference?
A common point of confusion is the difference between the SFMA and the Functional Movement Screen (FMS). Both use movement patterns, but they serve fundamentally different purposes.
It asks whether an individual has the foundational movement quality to participate safely in exercise or sport, and is often used in athletic settings to identify injury risk before a problem develops.
The SFMA, by contrast, is a diagnostic assessment for people who are already in pain, used to determine why movement is impaired. It is more detailed than the FMS, breaking down each pattern to isolate the source of dysfunction. While FMS asks "can this person move well enough to train?", the SFMA asks "why does this person move poorly, and what do we do about it?"
How the SFMA Informs Treatment and Corrective Exercise
Once the assessment identifies whether a limitation is a mobility or motor control problem, treatment becomes highly targeted. If the issue is tissue extensibility or joint mobility, the clinician addresses that first; only after mobility is restored can motor control and stability be retrained effectively.
This avoids prescribing the same exercises to every patient with back pain.
A Real-World Example: Why Your Knee Pain May Be a Hip Problem
Consider a patient with chronic right knee pain during running. A standard evaluation might focus on the knee itself, but the SFMA reveals a different story: the single-leg stance pattern is dysfunctional and non-painful on the right side, and the breakout finds adequate knee mobility but poor hip abduction strength and limited ankle dorsiflexion.
The treatment plan does not begin with the knee. It begins with:
- Restoring ankle dorsiflexion through joint mobilization and calf stretching, because the restricted ankle forces the knee to compensate inward during the stance phase of running.
- Strengthening the hip abductors (gluteus medius) to control femoral rotation and prevent the knee from collapsing medially.
- Retraining single-leg stance with progressive balance and loading exercises so the nervous system learns to stabilize the new range of motion.
Only after these impairments are addressed does the clinician return to the knee itself, and in many cases, the knee pain resolves without direct treatment to the knee. This is the clinical logic of the SFMA: treat the cause, not the symptom.
What to Expect During Your First SFMA Session
Here is a step-by-step walkthrough of a typical initial SFMA session:
1. Intake and History (10-15 minutes). Your clinician asks about your pain history, what aggravates and eases it, and what activities you want to return to, focusing on how your pain behaves across different movements and positions.
2. The Top-Tier Movement Tests (15-20 minutes). You perform the seven fundamental movement patterns while the clinician observes quality, notes compensations, and asks whether each reproduces your pain.
3. Breakout Testing (15-30 minutes). For any dysfunctional pattern, the clinician performs more specific tests, passive range of motion, manual muscle testing, and targeted movement challenges, to isolate the cause.
4. Immediate Feedback and Preliminary Plan (5-10 minutes). Unlike a standard evaluation, the SFMA provides immediate clinical reasoning. Your clinician explains what was found, what it means, and the first steps of treatment, so you leave understanding why you are in pain and what the path forward looks like.
The Role of Reassessment
SFMA-based care is not a one-time test. The assessment is repeated throughout treatment to objectively measure progress: if a dysfunctional pattern becomes functional, the intervention worked; if it remains dysfunctional, the plan is adjusted.
Most patients require 4-8 sessions to see meaningful changes in their top-tier movement patterns, though this varies based on the chronicity of the problem, the specific impairments identified, and how consistently the patient performs their home exercise program.
This precision is why patients at Spinal Haven often see progress when other approaches have stalled. The combination of one-on-one, personalized sessions with a movement-based assessment means every exercise has a purpose connected to your specific movement dysfunction.
McKenzie Method and SFMA Integration for Lasting Relief
The SFMA excels at identifying where movement breaks down, but it does not always answer why certain positions or movements are painful. This is where the McKenzie Method, also known as Mechanical Diagnosis and Therapy, complements the SFMA exceptionally well.
The McKenzie Method is a classification system that uses repeated movements and sustained postures to determine how a patient's pain responds to mechanical loading. It is particularly effective for spinal pain, helping clinicians identify whether symptoms centralize, peripheralize, or remain unchanged with specific movement directions.
Integrating the McKenzie Method with the SFMA gives clinicians a powerful diagnostic toolkit. The SFMA identifies the dysfunctional movement pattern; the McKenzie Method determines which specific movements or postures will reduce or eliminate the pain.
Spinal Haven is uniquely positioned to offer this integrated approach, as Dr. Elizabeth Kingshott Cary, PT, DPT, Cert. MDT, is both certified in the McKenzie Method and trained in the SFMA. This dual expertise allows for a level of diagnostic precision that is uncommon in standard physical therapy settings.
How to Fix Rounded Shoulders from Desk Work with an SFMA Approach
Rounded shoulders from desk work are one of the most common movement complaints we see. The SFMA approach begins not with the shoulders themselves, but with a full movement assessment to understand the entire postural chain.
But the SFMA asks whether the limitation is in the shoulder joint itself or a motor control problem from prolonged sitting, the answer determines treatment.
If the assessment reveals a mobility dysfunction from tight pectoral tissues, the initial focus is on restoring joint mobility through stretches and soft tissue work. Once mobility is restored, the clinician retrains motor control, often strengthening the lower trapezius and serratus anterior muscles, which hold the shoulder blades in proper position.
The key insight is that posture is a movement behavior, not a static position. You cannot stretch your way to better posture if your nervous system does not know how to hold the new position.
Start with a Root-Cause Assessment
Chronic pain that has resisted previous treatment often shares a common thread: the underlying movement dysfunction was never identified. The SFMA exists to close that gap.
If you have tried generalized physical therapy without lasting results, a movement-based assessment may reveal what previous approaches missed.
At Spinal Haven, we offer one-on-one, personalized physical therapy sessions built around this integrated assessment approach. Our focus is on patient education and long-term self-management, so you leave with the tools to manage your movement with confidence, not a dependence on endless appointments.
Frequently Asked Questions
How does SFMA differ from a standard physical therapy evaluation?
A standard evaluation often focuses on the area where you feel pain, like your lower back or neck. The SFMA is a whole-body movement-based diagnostic system. It assesses how your body moves through fundamental patterns to find the root cause, which may be a mobility or stability dysfunction in a different area driving your symptoms. This allows for more specific and effective treatment.
Can SFMA help identify the root cause of chronic back pain?
Yes. Because it breaks down movement into top-tier and break-out tests, the SFMA can reveal non-painful movement restrictions that create compensatory patterns, often leading to back pain. By identifying the source of the problem, it helps guide treatment toward the true cause of your pain rather than just treating the symptoms.
What is the difference between SFMA and FMS?
The Functional Movement Screen (FMS) is a screening tool used to assess baseline movement quality, often for injury risk in athletes or active populations. The Selective Functional Movement Assessment (SFMA) is a diagnostic assessment used by clinicians to evaluate individuals who already have pain. It is a more detailed, top-tier clinical model used to guide treatment and corrective exercise.
Who should perform an SFMA evaluation?
An SFMA evaluation should be performed by a trained healthcare professional, such as a physical therapist, who has completed the official SFMA training. This training ensures they understand the diagnostic algorithm and can accurately differentiate between mobility and stability dysfunctions to guide your treatment effectively.
Chronic pain and movement limitations do not resolve by treating symptoms alone. They require understanding the root cause of your movement dysfunction. Spinal Haven combines the only clinician in Michigan trained in both the SFMA and certified in the McKenzie Method with personalized, one-on-one sessions designed to restore your strength and return you to the activities you love. Book a discovery call and start with an assessment that finds the source of your pain.
