A Fresh Look At Manual Therapy

"What would happen if manual therapists focused on brain function, spinal cord function, and nerve function, instead of tissue?


I think we would listen very closely to patients’ accounts of their pain, explain nerves in detail, explain pain way better in ways patients could understand, with their own story details woven back in. I think we would teach our patients how to own and practice locus of control over treatment, and the importance of maintaining a boundary around their own relaxed comfort levels. I think any manual therapy provided, any results from it and from any movement homework afterward, would be considered by both parties, and both parties’ brains, as having been arrived at mutually, interactively. I think we therapists would enhance our abilities to elicit favorable descending modulation for pain from another’s brain, through awareness of how touch and handling of periphery and peripheral nerve is perceived by the brain attached, instead of imagining we were doing things to change structure or tissue. (...)

I think that that judicious sensory rehabilitation, first, can help people with non-medical pain move easier, feel more inclined to participate in motor rehabilitation, and thereby avoid unnecessary surgery. (...)"

DNM in a Nutshell

1. Addressing skin, dragging it a little, activates exteroception, interoception, and also activates proprioception. No need to pretend one can bypass skin and focus on muscle or joints, or release fascia.

2. Cutaneous nerves [physically] innervate underlying [outer layer of] fascia and tendon. Just tugging on skin will drag on these inwardly disseminating rami a bit.

5. Sensory neurons produce endogenous peripheral opioid receptors. Perhaps stimulating the skin organ deliberately can help create reduction in peripheral nervous system nociception.

"DermoNeuroModulating, or -tion, is a structured, interactive approach to manual therapy that considers the nervous system of the patient from skin cell to sense of self. Techniques are slow, light, kind, intelligent, responsive and effective. Positioning of limbs and trunk affects deeper nerve trunks (by shortening and widening their container), and is combined with skin stretch directed toward cutaneous fields of nerves that branch outward into skin (which may draw neural structure further through its container).
It is prudent to remember that manual handling of a patient's physicality is only a small part of developing a complete therapeutic context for change - while optional, it can also be optimal."
