The sensing and “phase changing” nature of fascia in motion.

Pandiculation is one of nature’s homeostatic blueprints; It is the body’s way of resetting itself after a period of restful sleep or inactivity. A motion arises that follows the spiral pattern of fascial continuity, triggering a body-wide “phase change” from stiff to supple; nourishing, revitalising and restoring the vibrancy of the tissue from the inside out. Pandiculation has been variously described as:

“The act of stretching and yawning”

 “A stretching and stiffening of the trunk and extremities”

Or The Hanna Somatics version: “A voluntary contraction of a muscle. Followed by a slow controlled lengthening and a complete relaxation.”

Through the lens of fascia and biotensegrity we discover a unique experience in pandiculation – one that does not feel like a stretch or individual muscle contraction. The body shape-shifts in response to sensory feedback within the fascial matrix. Fascia as a sensory tissue has been described as an organ of communication (Robert Schleip). As intertwined with the nervous system. With mechanoreceptors providing the environment for proprioception and interoception. Also described as electromagnetic and quicker to react than the nervous system (James Oschman), fascia is a sensory organ itself creating piezo-electric effects throughout the structure in response to mechanical stress.

Through a fascia-sensing lens, how do we describe pandiculation?

An urge to move arises from within, accompanied by a spontaneous in-breath and sense of expansion. The breath is held in suspension, as the body intuitively self-explores and unwinds to its inner pattern of embodiment. (Thanks to the mechanosensitivity of fascia).

There’s an “ooh I just need to get into there” feeling. Like an inner massage.

At the end is a satisfying sigh and a sense of wellbeing, the body feeling less stiff, softer, and awake.

How does this translate into structural integrity and wellbeing?

  • The urge is an interoceptive signal. It happens when fascia is in homeostatic resonance. Trauma, learned movement patterns, lack of movement, chronic stress and any long-term dysregulation disconnects us from this intuitive urge.
  • A spontaneous in-breath maintains structural integrity, preventing the structure from straining in any one part.
  • The whole body moves in effortless motion, following an innate pattern.
  • The sense of expansion is the omnidirectional way in which fascia responds.
  • The motion reaches dense areas of tissue, like the thoracolumbar fascia, which are prone to strain, pain, and stiffness.
  • The accompanying breath restores a healthy function of the fascial diaphragms and breathing.
  • The tissue “phase changes” from stiff to supple in response to sensation.

Stephen Levin’s biotensegrity offers an insight into the nature of structural efficiency and effortless motion. The body is not a 2-dimensional, stacked structure of mechanical levers and parts that move individually. We are 3-dimensional and held by the forces of tension and compression, giving rise to volume. It means that we do not need effort to stay upright against gravity. Nor do we move individual parts in isolation. In biotensegrity, when we move, everything moves.

Stretching is associated with the way elastic materials, when pulled, become thinner. Linked to flexibility and mobility around a joint. It’s a learned motion based on 2-dimensional, musculoskeletal anatomy. Yoga, gymnastics, and ballet are examples. Stretching at a joint can deform ligaments over time beyond their integrity. (John Sharkey).

In pandiculation we are experiencing the auxetic nature of fascia. Auxetic materials expand and are shock absorbing. The shape-changing motion of pandiculation triggers a homeostatic phase change in the fascial matrix.

Phase change describes the changing state of a substance from solid to liquid to vapour. Like water. Except that water has a 4th phase. That is neither solid nor liquid but a gel. (Dr Gerald Pollack – 4th phase of water). We are 60 to 70% water that is gel-like. Or viscous in nature. Lack of movement, hypervigilance, or over exercising changes the viscosity of fascia, causing strain, stuckness, pain or inflammation.

Moving the way Nature intended restores fascial integrity, hydration, vibrancy, and resonance. Providing an optimum homeostatic environment for regeneration and wellbeing.

The same body-wide “phase change” phenomenon happens in manual therapy; the tissue melting under the hand of the therapist, even with a light touch. This “light touch” approach is opening new and simple approaches for manual and movement therapy. It is much more effective than foam rollers and deep tissue manual therapy of individual muscles.

Meet Yasmin Lambat, Master Somatic Movement Therapist, Educator, and Founder of SomaSensing Body Unwinding. A trauma healing somatic movement practice based on the emerging research on fascia, biotensegrity, and nervous system regulation.

Her movement and manual therapy experience spans 30 years. It includes training as a Yoga and Polestar Pilates teacher as well as a myofascial release therapist. It was her introduction to somatic movement that paved the way to somatic healing.

As an experienced educator, presenter, and workshop host, Yasmin has developed a reputation for delivering engaging, informative, and impactful workshops on fascia informed somatic movement therapy. She has presented at numerous conferences and events, both nationally and internationally, and has had the privilege of working with diverse populations, including physiotherapists, chiropractors, Pilates teachers, osteopaths, and yoga teachers.

In her workshops and coaching services, Yasmin draws on the latest research and best practices in the field to provide a practical embodied experience for integrating somatic movement therapy and somatic practices into participants' lives.
