Functional Range Release

The hands-on half of the system we train with.

Functional Range Release, or FR, is a system for assessing and treating soft tissue, developed by Dr. Andreo Spina, the same person who built Functional Range Conditioning. At Motive, FRC is how we train joints and FR is how we assess and treat the tissue around them. It uses massage techniques inside a framework that finishes every piece of hands-on work with the joint producing force at whatever range showed up. This page covers what FR looks for and where it fits at Motive.

How it works

What FR is
FR is one piece of Functional Range Systems, the family that also includes FRC, the Functional Range Assessment, and KINSTRETCH. Spina built all of them on one model of how joints and connective tissue adapt to the forces put through them, so the hands-on work and the training speak the same language and hand off to each other cleanly. Functional Range Systems describes FR and FRC as a continuum, with FR at the clinical, hands-on end and FRC carrying the same principles into training.

FR certification is split by body region into upper limb, lower limb, and spine, and each certification covers the assessment and treatment methods for its region. Brian Murray is FR certified in the spine and the lower limb.
What FR looks for under the hands
A lot of hands-on work gets explained through knots and scar tissue that a therapist can find and break up. FR sets that explanation aside early. Scar tissue, in the technical sense, is ordinary connective tissue laid down in a disorganized direction, and a single misaligned fiber is far too small for human touch to detect. What hands can feel is tension: tissue resisting a movement it should allow, or layers that ought to slide past each other and won’t.

So an FR assessment is a search for abnormal tension, followed by a call on what kind it is. Mechanical tension comes from the tissue itself, connective tissue that has remodeled in a way that restricts movement. Neurological tension is the nervous system holding a tissue tight, and protective spasm is a version of it we can feel directly on the table. The two can feel alike under the hands and they need different work, so that call gets made before anything is treated.
What the hands are working on
Muscle is contractile protein wrapped in layers of fascia, and that fascia runs continuously into tendon, ligament, joint capsule, and bone. When tissue is injured, or loaded the same way for years, much of the remodeling happens in that connective tissue. Collagen gets laid down in random directions and layers stop sliding past each other, which shows up as stiffness where there used to be give. That connective tissue is what FR targets.

The release part (release in quotes, since nothing in the tissue lets go like a knot coming untied) is sustained, specific force applied to the tissue the assessment pointed to. It’s designed to reduce tissue tension and intended to influence how that connective tissue remodels over the following weeks. Connective tissue adapts on a slow clock, and FR is planned around it.
What changes on the table, and what takes longer
Range often shows up during a session, and it’s worth being straight about what that probably is. A 2008 modeling study calculated that firm fascia like the fascia lata and plantar fascia would need forces well outside anything hands can produce to compress or shear it by even 1% (1). A 2025 review pulling together 62 reviews on how manual therapy works found moderate-quality support for neurological and neurovascular effects, and only critically low-quality support for biomechanical ones (2). Put those together and the quick change on the table is most likely the nervous system easing its guard. That’s useful, because a range the nervous system has just stopped guarding is the right moment to load it.

The slower change is where load does most of the work. Cells in tendon, muscle, and connective tissue sense mechanical load and remodel in response to it, a process called mechanotransduction, and it’s the reason exercise gets prescribed for tissue repair (3). FR is built around that sequence. The hands are meant to reduce tension and give the nervous system room to let go, and the loading that follows gives the tissue a reason to change.
Where the training comes in
Every piece of FR work ends with the person on the table doing the work. Once new range shows up it gets loaded straight away with PAILs and RAILs, hard isometric contractions at the edge of that range. Inside FR they put internal load through the tissue that was just worked on and build strength at the exact angle where the new range lives, which gives the nervous system evidence it can control that position.

From there the work moves to the gym floor. The same tools, CARs and PAILs and RAILs among them, run through FRC training and through KINSTRETCH classes. That’s why we treat manual therapy and training at Motive as two halves of one system. The hands-on work opens a position, and training is how someone keeps it.
How FR differs from deep tissue massage
Deep tissue massage uses slow strokes and firm, sustained pressure to reach the deeper layers of muscle and fascia, usually concentrated wherever someone feels the most tension or soreness. It can settle down an area that has been nagging for weeks, and plenty of people get a lot out of it. FR uses some of the same massage techniques. It parts ways in how a session gets planned and how it ends.

In FR, where the hands go comes out of an assessment. We want to know which joint is short on range, which tissue is producing the tension that limits it, and what kind of tension that is, and pressure gets chosen for that tissue at that layer. When the tension turns out to be neurological, more pressure is the wrong tool, so it gets a neurological input instead, like a contraction or a position the nervous system will accept. Then the session finishes with the client contracting hard at whatever range opened up, a step deep tissue work usually leaves out.
Who FR suits
FR earns its place when the thing limiting a joint lives in the tissue, or in the guard the nervous system keeps around it, and training keeps running into it. A joint’s passive range can be short to begin with, which leaves control work nothing to build on yet. Other times a position opens up after stretching or massage and is gone within a day or two, a pattern that points at tension the nervous system hasn’t let go of. Post-rehab is another: a hip or ankle that physical therapy cleared, and that still feels stuck under load. Movement that hurts well short of any real end range gets hands-on attention before anything is loaded at all.

It’s a poor fit for someone who wants a relaxation massage, which is a different kind of work. It’s also the wrong first stop for an acute injury a doctor hasn’t looked at, or a flare-up that needs medical care. We don’t diagnose conditions, and when something needs that, we say so and point you to the right person.

One system, every program

Where FR shows up at Motive

At Motive, FR is how we assess and treat. On the assessment side, FR's palpation and its read on tissue tension sit on top of the joint-by-joint model from the Functional Range Assessment. Once we know a joint won't move through its range, FR is how we find what's holding it and what kind of tension it is. Treatment is the hands-on work itself, followed in the same session by loading at the new range, and then by the training that keeps it.

How hands-on sessions run is covered on the manual therapy page.

FAQ

Questions about FR

What is Functional Range Release?

Functional Range Release, or FR, is a soft tissue system developed by Dr. Andreo Spina for assessing and treating tension that restricts how a joint moves. It's the hands-on side of Functional Range Systems, the same family as FRC and KINSTRETCH, and every treatment finishes with isometric loading at the new range. At Motive, FR is how we assess and treat.

Is FR a type of massage?

FR uses massage techniques, applied inside a framework a traditional massage doesn't use. Each session starts from an assessment of the joint and the tissue limiting it, and ends with the client contracting at whatever range opened up. The aim is range the client can use and produce force in.

Does FR break up scar tissue?

No, and the system itself says so. Scar tissue is connective tissue laid down in a disorganized direction, at a scale touch can't detect, so FR works from tissue tension. The hands-on work is designed to reduce that tension and intended to influence how the tissue remodels over time, and the loading afterward carries a large share of that.

How is FR different from FRC?

They run on the same principles from two directions. FR is hands-on work on the tissue, done by a practitioner. FRC is training the person does, built around CARs and end-range strength work like PAILs and RAILs. PAILs and RAILs show up in both, and that's where one hands off to the other.

Is FR evidence-based?

FR as a named system hasn't been tested in published trials; as of October 2026 a PubMed search for it turns up nothing. The pieces it's built on have research behind them in different amounts. Load driving connective tissue adaptation is well supported. How hands-on work produces its effects is less settled, and the current evidence points more toward the nervous system than toward physical change in the tissue. We've laid out what the manual therapy research shows, and where it runs thin, in our breakdown of manual therapy.

Who performs FR at Motive?

Brian Murray, who is FR certified in the spine and the lower limb. He also holds FRCms, FRSC, FRA, and KINSTRETCH Level II certifications through Functional Range Systems.

Do I need FR to train at Motive or take a KINSTRETCH class?

No. Plenty of people train for years without hands-on work. FR comes in when an assessment shows the limit is tension in the tissue or guarding around a joint, and training on its own keeps running into it.
