I haven’t talked very much about Integrated Listening Systems, or iLs, in the past. Most of my writing about therapeutic listening has focused on the Safe and Sound Protocol and, more recently, the Rest and Restore Protocol. Recently I posted this article on how I decide between those two approaches.
Lately, however, my thinking has been shifting.
I am increasingly recognizing a particular group of highly complex and sensitive people for whom iLs may be the best place to begin - not because I now believe that iLs should routinely come before SSP or RRP, but because these individuals may not be able to risk even a temporary increase in dysregulation.
For many people, I would still recommend SSP first. A relatively rapid shift in physiology can create an excellent platform for iLs, neurofeedback, psychotherapy, rehabilitation, and other approaches to work more efficiently. This is what I found on my own iLs journey.
For some people, beginning with RRP may provide needed restoration before either SSP or iLs.
But when someone is already at the absolute limit of what they can manage, the sequencing question changes. The priority may need to be building more regulation with the approach that, in my clinical experience, carries the lowest risk of making things temporarily more challenging.
That realization is why I am now talking much more about iLs.
There is no single correct order for listening programs.
For many people, I would recommend completing the Safe and Sound Protocol (SSP) before beginning Integrated Listening Systems, or iLs. SSP can shift physiology relatively rapidly. When it is well tolerated, that shift may create a better platform for iLs to work more efficiently and effectively.
The same principle applies beyond iLs. SSP may help someone become more receptive to neurofeedback, psychotherapy, rehabilitation, and many other approaches. When the nervous system is less occupied with protection and survival, subsequent interventions may have more to work with.
For some people, however, I might begin with the Rest and Restore Protocol (RRP). If depletion, exhaustion, difficulty settling, or limited restorative capacity is central to the presentation, RRP may provide the most appropriate starting point. When it is well tolerated, supporting rest and physiological restoration first may prepare the person for either SSP or iLs.
But there is another group for whom I increasingly consider beginning with iLs.
These are not simply people with complex histories or multiple diagnoses. They are people who are extremely sensitive, already living at the limit of what they can manage, and unable to risk even a temporary increase in how rough things feel.
For them, the question is not only which program might ultimately be most helpful. We also have to ask:
Does this person have enough physiological reserve to tolerate the possibility of becoming more dysregulated before becoming better regulated?
If the answer is no, iLs may be the more appropriate place to begin.
Both SSP and RRP can be carefully titrated. With sensitive clients, listening may be reduced to very small amounts.
However, some people become dysregulated even from micro amounts of SSP or RRP. Their responses may be immediate or delayed, and the intensity of the response is not always proportional to the amount of listening.
This does not mean that SSP or RRP is inherently too intense for complex people. Some highly complex clients respond beautifully to one or both. A person who is unable to tolerate SSP may do well with RRP, while someone else may tolerate SSP much more readily than RRP.
The names and intended purposes of the programs cannot tell us how an individual nervous system will respond.
For someone with adequate reserve, a temporary increase in symptoms may be manageable. We can pause, support regulation, adjust the listening plan, and allow time for integration.
But some people have no such margin.
They may already be using almost all their available capacity to manage pain, sensory overload, cognitive demands, autonomic symptoms, sleep disruption, emotional distress, or the basic activities of daily life. Even a brief worsening could significantly affect their ability to work, care for themselves, tolerate food, sleep, communicate, or remain emotionally stable.
In these circumstances, “start with a tiny amount” may not provide enough protection.
The problem is not necessarily that the dose is too large. The person may not yet have enough regulation and resilience available to integrate the kind of physiological shift that SSP or RRP can produce.
In my clinical experience, iLs has little to no risk of causing dysregulation, including among many extremely complex and sensitive clients.
iLs is also, of course a wonderful approach all on its own.
It is possible for someone to become temporarily overstimulated if they do too much iLs in a short period of time, but simply switching to the iLs Calming music or taking a few days off tends to be enough for that to settle.
That gives it a distinctive role when our first priority is to increase regulation and neurological organization without risking a significant destabilizing response.
Beginning with iLs does not mean deciding against SSP or RRP. Quite the opposite. The purpose may be to help the nervous system become sufficiently organized and regulated that one of those programs can be introduced later with much less difficulty.
After completing some iLs work, we may find that the person can tolerate SSP or RRP much more smoothly than they likely would have at the beginning. What was initially too much for the nervous system may become manageable - or even easy - once more regulation is on board.
In this sense, iLs can sometimes serve as a bridge.
One person’s sequence may be:
SSP → a relatively rapid physiological shift → greater receptivity to iLs, neurofeedback, or other therapies
Another person’s may be:
RRP → greater rest and restoration → increased capacity for SSP or iLs
And for someone with almost no margin for additional dysregulation:
iLs → greater regulation and neurological organization → a smoother introduction to SSP or RRP
None of these sequences is inherently superior.
The appropriate order depends on what is limiting the person now and how much change their nervous system can safely integrate.
RRP deserves to be considered in its own right rather than simply treated as an alternative version of SSP.
Some people appear to need restoration before they need further activation, organization, or increased social engagement. They may be profoundly depleted, unable to settle into restorative states, or caught in a pattern in which their nervous system never seems to replenish its resources.
For them, beginning with RRP may make excellent sense. If RRP is well tolerated, improving the capacity for rest and physiological restoration may create a stronger foundation for SSP, iLs, or other therapeutic work.
At the same time, “restorative” does not automatically mean risk-free. Some extremely sensitive people become dysregulated by very small amounts of RRP, just as some do with SSP.
An invitation toward rest can itself represent a significant physiological change, particularly when the nervous system has been organized around chronic mobilization, vigilance, or survival.
This is why I would not choose RRP first based only on exhaustion or depletion. I would also consider the person’s history of responding to physiological change, their current reserve, their ability to identify early signs of overload, their usual nervous system patterns when under stress, and the consequences if their symptoms temporarily worsen.
People with a history of concussions or brain injury - or neurological presentations with similar features - may be particularly important candidates for an iLs-first approach.
Brain injury can leave someone with a much lower threshold for stimulation and change. They may experience cognitive fatigue, headaches, sensory sensitivity, impaired attention, vestibular difficulties, sleep disruption, emotional lability, autonomic symptoms, or difficulty recognizing overload until they have already exceeded their capacity.
Responses may also be delayed. An intervention can appear well tolerated during a session but lead to a marked increase in symptoms later that day or over the following days.
This does not mean that people with brain injury cannot benefit from SSP or RRP. Some may benefit greatly, and RRP might be a valuable first step when depletion and restoration are the dominant concerns.
It does mean that the cost of getting the timing or dose wrong may be particularly high.
I have at times used carefully titrated SSP to help people recover from post-concussion syndrome and it has gone very well.
However, for a small subsection of people even micro amounts of SSP and sometimes RRP has triggered vestibular symptoms.
When someone has very little neurological reserve, iLs may offer a way to begin supporting sensory-motor organization and regulation without requiring a rapid physiological shift. If that work increases stability and capacity, SSP or RRP may become considerably easier to tolerate later.
I am not recommending that iLs routinely precede SSP or RRP.
For many people, beginning with SSP will be the better and more efficient choice.
When SSP produces a relatively rapid improvement in physiological regulation, it can create a stronger platform for everything that follows.
For others, beginning with RRP may go particularly well. I saw an interesting example of this when I was lucky enough to help with the RRP pilot study.
Some of the my own pilot study clients had already begun SSP before the pilot started. We paused their SSP listening while they completed RRP. When they returned to SSP afterwards, they were able to listen at a faster pace than they had before doing RRP.
That does not mean RRP is always the gentler place to begin. For some people, RRP may be profoundly restorative. For others, even a small amount of RRP can be quite dysregulating. The same program can land very differently in different nervous systems.
My decisions about where to begin have therefore never been based on a formula in which SSP does one thing and RRP does another. I look at the person’s entire presentation and try to determine which program - and which sequence - they are most likely to respond to well.
What has changed is that iLs now has a more important place in that decision.
I increasingly consider beginning with iLs when someone is so sensitive, depleted, or neurologically vulnerable that they cannot safely absorb even a temporary increase in dysregulation. This may be particularly relevant for people with brain injuries and for those who are already functioning at the absolute limit of what their nervous system can manage.
The questions become:
Which program is this particular nervous system most likely to receive well right now?
How much capacity does the person have to absorb an unexpected or temporarily difficult response?
Which sequence is most likely to make the next step easier and smoother?
Sometimes beginning with SSP creates a better platform for RRP, iLs, or other therapeutic work.
Sometimes beginning with RRP makes a later experience of SSP go much more smoothly.
And sometimes beginning with iLs may build enough regulation that SSP or RRP becomes much gentler for someone who might otherwise have found even a micro-dose too much.
Good sequencing is not about following a preferred order or assigning each program a fixed role. It is about solving the puzzle of what this particular nervous system is most likely to respond to well - and finding the gentlest path towards where we hope to go.d
