When movement is painful, assessment should help determine what the person can do next.
The Selective Functional Movement Assessment, usually called the SFMA, is one framework for organizing painful and limited movement, deciding which findings deserve closer examination and identifying when treatment, exercise or referral may be appropriate.
At Lee Strength, its value is practical: connect the painful activity to an in-scope assessment, change one relevant variable and reassess the outcome that matters.
How is the SFMA different from the FMS?
The FMS and SFMA serve different starting points.
The Functional Movement Screen is designed primarily for people who are not in pain during the screen. It observes seven standardized patterns to inform fitness and programming decisions.
The SFMA is designed for people with musculoskeletal pain. It begins with larger movement patterns and classifies what the practitioner observes before deciding which region or function may deserve more focused assessment.
In simple terms:
- FMS asks how a generally pain-free person performs standardized movement patterns.
- SFMA asks which movements are painful or limited and what should be assessed more closely.
Neither system replaces a medical diagnosis or a complete professional assessment.
What does the SFMA classify?
The SFMA uses four broad movement classifications:
- functional and non-painful
- functional and painful
- dysfunctional and non-painful
- dysfunctional and painful
This creates a consistent way to separate pain from movement limitation.
That separation is useful. A person may move through a range but experience pain. Another person may move differently from the framework's criteria without pain. Those situations should not automatically receive the same explanation or intervention.
What happens after a movement is classified?
When a pattern is painful or limited, the practitioner may examine relevant regions, movements and functions more closely.
The purpose is to narrow the next assessment question, not to assume that every limitation is caused by a tight muscle, weak core, faulty fascia or distant joint.
Depending on the presentation and the professional's scope, the next step may include:
- a more focused soft-tissue or joint assessment
- neurological or medical screening
- review of training or occupational demands
- comparison of active and passive movement
- tolerance to load
- treatment followed by reassessment
- referral to another regulated professional
The SFMA flowcharts and detailed procedures are practitioner tools. They do not need to be reproduced publicly for a prospective client to understand the purpose of the assessment.
What can the SFMA tell us?
The SFMA may help a trained practitioner:
- use a repeatable movement-assessment structure
- separate painful from non-painful findings
- identify a movement that deserves closer examination
- avoid focusing only on the location where symptoms are felt
- organize reassessment after an intervention
- recognize when the presentation does not fit the practitioner's scope
It cannot establish by itself:
- a medical diagnosis
- the exact tissue causing pain
- that one remote body region caused the symptom
- that a movement variation predicts future injury
- that an SFMA-based treatment will outperform other appropriate care
The assessment is a reasoning framework. Its value depends on the person using it, the broader examination and what happens after the finding.
What does the research show?
Most published SFMA research has examined scoring reliability rather than whether SFMA-guided care improves important outcomes.
Reliability studies suggest that scoring consistency varies by movement and assessor experience. More experienced raters have generally demonstrated better agreement than less experienced raters.
That supports training and standardized use. It does not prove diagnostic accuracy or treatment effectiveness.
A critically appraised review of SFMA use in dancers found only low-quality evidence, largely case reports and small observational studies. The appropriate conclusion is that the SFMA can be a useful clinical structure, but its outcome claims should remain modest.
Why regional interdependence needs careful language
The SFMA encourages practitioners to consider whether movement outside the painful area may be relevant.
That can be useful. A shoulder complaint may coexist with neck symptoms, trunk movement limitations or training demands. Back pain may be influenced by hip motion, load tolerance, sleep, work exposure and many other factors.
The concept becomes misleading when it is converted into certainty:
- "Your ankle is the root cause of your back pain."
- "Your shoulder hurts because your opposite hip is dysfunctional."
- "This movement proves exactly where the problem begins."
Movement findings may guide an assessment. They do not prove a single causal chain.
Can regional interdependence still guide care?
Yes, when it is treated as a hypothesis.
Movement in one region can change the demands placed on another region during a task. A shoulder complaint may therefore justify looking at the neck or trunk, and a back complaint may justify examining hip movement or load tolerance.
A responsible process is:
- Identify the painful or limited task.
- Examine a plausible contributing region within professional scope.
- Change one safe variable.
- Reassess the original task.
- Track whether the response is repeatable and functionally useful.
If the original task improves, the remote finding may be relevant for that person. The result still does not prove that the remote region was the single cause of pain.
How a remote finding earns relevance
Looking away from the painful area is useful only when it improves the original question.
Suppose shoulder movement is painful and trunk position changes the movement. That observation creates a hypothesis that trunk contribution may matter. It does not prove that the trunk caused the shoulder pain.
The hypothesis earns more weight when:
- the original painful movement changes predictably
- the change repeats
- an in-scope intervention directed at the relevant contributor improves the same task
- the improvement transfers to work, training or sport
It loses weight when the remote finding looks unusual but changing it does not affect the complaint.
This is the practical value of regional interdependence. It encourages a broader assessment without granting permission to invent long causal chains across the body.
How the SFMA may fit within Registered Massage Therapy
In Ontario, the scope of Massage Therapy includes assessment of the soft tissues and joints of the body and treatment or prevention of physical dysfunction and pain of those tissues and joints through manipulation.
Within that scope, I may use movement observations and SFMA-informed reasoning to:
- understand which movements reproduce or change symptoms
- guide an in-scope soft-tissue and joint assessment
- select and explain a treatment plan
- reassess a meaningful movement afterward
- recognize when another professional should assess the problem
The SFMA does not expand RMT scope. I do not use it to claim a medical specialty or communicate a medical diagnosis.
What should a useful assessment lead to?
A movement assessment should improve the decision that follows.
It may clarify:
- whether RMT care is appropriate
- whether exercise should be modified or progressed
- which outcome should be retested
- whether another healthcare professional is needed
- whether the current explanation fits the person's response
If a complex assessment produces only a dramatic label and no clearer plan, it has not done enough.
When another assessment takes priority
Movement assessment should not delay medical care for rapidly worsening weakness, altered coordination, major trauma, chest pain, severe or worsening headache, new bowel or bladder dysfunction, saddle-area numbness, fever with severe pain or other acute neurological or systemic symptoms.
Persistent symptoms that fall outside RMT or strength-and-conditioning scope should be referred rather than relabelled as a movement dysfunction.
How the SFMA fits at Lee Strength
At Lee Strength, SFMA-informed assessment would be one part of an assessment-led process. It would not be sold as a root-cause diagnosis or a guaranteed path to pain relief.
I have completed SFMA Level 1 and Level 2 certification training. The framework may inform an in-scope assessment, treatment decision and referral process, but it does not expand the legal scope of Registered Massage Therapy.
The purpose is practical:
- Understand the activity or movement that matters to you.
- Determine whether the presentation fits my scope.
- Assess relevant soft tissues, joints and movement.
- Select treatment or exercise for a clear reason.
- Reassess the same meaningful outcome.
- Refer when a different professional is needed.
The framework should serve the client. The client should not be forced into the framework.
