This Evolving SLP



As a Speech Language Pathologist (SLP), I am often asked by parents and interdisciplinary peers how and why I clinically use manual strategies and neuromuscular reeducation techniques vs more conventional approaches. My response is simple. When my son was formally diagnosed with Autism, I found it necessary to learn all I could about the human body. I had to know more about this condition, and what I could do to help him be part of a world that was difficult to participate and function in.

How I assess and treat for function and participation, is based on the synchrony of systems, i.e., digestive, respiratory, fascia and “physics” as it applies to pressure and alignment, i.e., upright head positioning, postural alignment, jaw symmetry, foot positioning, points of stability from the feet to the head. Why do I do this? Well, conditions I assess and treat within my line of work are primarily not so overt (“obvious”) and tangible (“visible”). For example, let’s take a common musculoskeletal condition like lateral epicondylitis (Tennis Elbow). Overt symptoms include pain, decreased range of motion, and loss of strength. Identifying the underlying factors contributing to lateral epicondylitis are typically tangible and can be physically assessed. Treatment approaches can also be tangible and conventionally applied.

But what does Autism “look” like? What do sensory aversions “look like”? What and where are the overt and tangible regions to treat? I often joke that I wish I had my son’s “guidebook”. That way, I could turn to the page that tells me why loud sounds lead to meltdowns, and which treatment strategies I can incorporate to help address underlying factors that improve noise toleration!

In my line of work etiologies like “Speech Language Delay”; “Dysphagia”, “Cognitive Communicative Disorders” are neither overt nor tangible. They also appear to present with underlying factors associated with afferent processing pathways affecting motor behavior.


Click here for a diagram that demonstrates the physical symptoms of an afferent processing pathway (“anxiety”). This gives an idea how respiration, blood/lymphatic circulation, body temperature, and digestive functioning can be impacted: http://tophealthnews.net/wp-content/uploads/2016/03/If-You-Have-Panic-Attacks-and-Anxiety-You-Should-Look-for-THIS-Cause.jpg

Professionally, I felt the need to learn manual strategies and neuromuscular reeducation techniques as there are neuromusculoskeletal and biomarker components that interplay as relevant co-morbidities, additional pathologies, and secondary impairments associated with speech, language, hearing, and related disorders like dysphagia. (Table 1). This list is not all-inclusive, but it gives you an idea that afferent processing pathways and motor behavior are more integrated than one thinks! Communication to motor efferents, blood and lymphatic circulation, digestive functioning, strong respiration and immune system functioning, core/surface temperature relationships, and the result of joint alignment, are some of the physiological factors that influence multi-system interactions.

I have found neuromusculoskeletal and biomarker components to be the “overt” and “tangible” areas that can be assessed and treated to improve motor behavior. They can also be measured objectively to interpret gains associated with targeted functional outcomes, data collection on co-morbidities, neuromusculoskeletal alignment, and secondary impairment improvement. In my experience, the neuromusculoskeletal components have addressed “why” the problem behavior may be occurring. The physical symptoms of the problem are typically associated with afferent processing pathways, but still appear to be affecting musculoskeletal/neuromusculoskeletal performance.

Working in this manner promotes the American Speech-Language-Hearing Association (ASHA) support of the World Health Organization (WHO) ICF framework. The domain, Body Structure and Function, encourages clinicians to include and assess for physiological data (biomarkers). Data from this is recommended to be used with the other three domains to interpret a person’s general health and wellness to develop an individualized plan of care.










































This Evolving SLP continues to learn more about the other “brains” of the body, i.e., Central Nervous System, Skin as the “outer brain”, Digestive System, Respiratory System, Immune System and manual techniques using tools and instrumentation. Why? Because literature cites these key points:

 In terms of “cognition”, the word “cognition” is not referenced as “intellect”. Instead, it is being references as “cognitive factors” (skills associated with “cognition”).

➤Neuroplasticity is improved by modalities that use light, sound, vibration, and movement- (Doidge, 2015).

Communication to motor efferents, i.e., the strength of blood and lymphatic movement; digestive, immune, and respiration system functioning; and the result of joint alignment, are some of the physiological factors that impact muscle performance. These components can be found in the skin, spinal pathways, and internal organ systems- (Harvey et al., 2017).

➤The nervous system does not differentiate between NOR work independently regarding sensation (generating and processing), function (motor output), or “cognition” (intention and problem solving)- Von Hofstein, 2007, Developmental Science.

➤Improvement in one system will promote improvement in all systems- (Adler, Lezlie 2017 from Combining the Principles of NDT and SI to Gain Function in Children with Neuromuscular Challenges).

➤Sensory input drives motor output!!! - (Harvey et al., 2017; Ito and Ostry, 2010).

➤Treatment methods that do not assess the underlying impairments impacting muscle strength and coordination neglect an understanding of the relationship of impairments to function- (Harvey et al., 2017).

➤Postural stability must be present for movements to control joints effectively. Movement before stabilization can produce abnormal shear forces both locally and globally- (Knott and Voss, 1968).

➤Postural control is influenced by cognitive factors like attention, motivation, memory, and intent- (Greters et al., 2016).

➤It is important to consider the underlying physiology of voice production and not just the behaviors that caused the disorder (Stemple, 2017). (I apply this statement to any problem behavior, not just voice production).


I look forward to sharing more of this line of work in future blogs. Ever onward!! - J
