Probably the most efficient therapy available to optimize how the brain controls movement and pain.
SMR can fix chronic pain and dysfunctional movement patterns for which people have been seeking a cure for years in a matter of a few sessions.
Initial injury = damaged sensory receptors = faulty sensory input = inhibitory safety response from brain = compromised stability = decreased range of motion = pain signals from compromised movement = pain causes brain to create dysfunctional movement patterns = new pain manifests further from original injury site = more dysfunctional movement patterns created etc.
For example, when a bike comes hurling towards you and you realize that impact is imminent, you are likely to lock down your muscles and brace yourself. You know the direction of force of the collision, thus your body knows how to negate that force to minimize the injury. These are all decisions made in split seconds that combine an array of sensory information with decisions made at a high level within your brain. Sensory information includes sight, where you are in space (proprioception), and previous knowledge of force (learned movement patterns).
However, when your brain receives faulty sensory information (usually due to injury), it does not have the same sophisticated mechanisms to distinguish the level of threat or a specific response. Therefore, the brain’s default safety mechanism when it receives faulty sensory information is to inhibit muscles.
If you have faulty proprioceptors in your ankle that are sending incorrect information to your brain about where your ankle is in space, the brain will respond by temporarily going into its default safety mechanism of inhibition. It does so because, in this default inhibited (weak) state, you are much less likely to rip muscles or ligaments off their boney attachments. It also decreases the likeliness of broken bones due to a transfer of force rippling from one joint to the next.
The downside of this safety mechanism is that you are also in a compromised state where your strength is decreased and you are less stable. When the nervous system feels unstable it will decrease the range of motion in your joints to regain stability (think tight muscles).
This inhibitory state is fleeting. Once the nervous system feels safe, it will send signals out for muscles to return back to normal function. However, if your nervous system is constantly getting faulty information, it will continue to send out that inhibitory signal. Pain can occur due to this compromised state and the nervous system starts to create compensation patterns to counteract the pain. Some of these patterns are poorly made choices by the brain that are ultimately identified in SMR as dysfunctional movement patterns.
To truly correct pain and dysfunction, we have to find the original sensory dysfunction that started the chain reaction of events. There are many types of receptors including: light touch, deep touch, hot, cold, vibration, point specific pain, broad pain, stretch etc. Stretch receptors are by far the most common dysfunction, but not the most significant to the brain. I have found faulty pain receptors to be the most significant catalyst for large ranging dysfunctions throughout the body.
The brain wants to be as functional as possible, therefore, once it is aware of dysfunctional receptors, the fix takes seconds and is permanent. It doesn’t need reinforcing with remedial exercises. The tricky part is not the fixing, but knowing what to fix, and that is where SensoriMotor Repatterning (SMR) excels.
