Psycho-Physical Unity: A Systems View of Human Functioning

In the Alexander Technique, you’ll encounter a foundational concept: psycho-physical unity. This principle asserts that human beings are not a collection of parts mind, body, emotions, and behaviour, rather humans operate as a single, integrated system. Alexander’s model asks us to consider not just the structure of the human body in isolation, but the relationship between the human system and its environment. 

In this blog, let’s explore the idea that we are not static objects in space, rather we operate as dynamic systems in relationship to our environment. Regardless of any other stimulus or threat that may be occurring in our environment a constant issue throughout our life is our orientation to gravity.

Gravity in Context: From Newton to Einstein

Traditionally, gravity has been described as a force pulling objects toward the Earth. Newton’s laws gave us a framework for understanding this pull in terms of mass and acceleration. Here gravity is a constant force exerting a force of 10² metres and time is an absolute unchanging flow. Einstein’s theory of general relativity reframed gravity, not as a force, but as the curvature of spacetime caused by mass-energy. In this model, objects move along paths (geodesics) determined by the shape of spacetime itself.  Spacetime is a four-dimensional continuum; three dimensions of space (height, width, depth), one of time, interwoven. In this model, every event has both a location and a moment.

This framework doesn’t imply that gravity “supports” us. It simply describes the conditions in which we exist. Our task is to coordinate ourselves within this curved field Now all of this may sound complex or confusing, bit it’s all about considering that we have a relationship to gravity. We are not passively oppressed by a force pulling us down. The question in this relationship, is where do we have agency?

Coordination, Not Resistance

We respond to gravity through neuromuscular coordination, skeletal organisation, and perceptual awareness.

The Alexander Technique cultivates agency not over gravity, but over how we organise ourselves in its presence.

This includes:

•  Inhibition of habitual bracing or collapse

•  Direction of intention and attention

•  Elastic counterbalance through interplay of compression and tension

 

Elastic Uprightness: A Suspension Model

The study of Alexander Technique provides us with the opportunity to explore a suspension model of uprightness. This is useful to us because it gives us the idea that there is an innate vitality in the way our joints, muscles and fascia work together.
Elastic uprightness arises from the dynamic interplay of compression and tension within the human system. Through weight-bearing, joint function, and fascial continuity, the body maintains upright coordination not by resisting gravity, but by distributing load across a responsive, integrated structure.

Uprightness is an activity not a passive state.

The main critique of an “elastic uprightness” model is that it can give the impression that human posture is maintained passively, as if the body were a suspension bridge held up by opposing pulls. In reality, upright coordination depends on the active regulation of postural tone by the nervous system, combined with the mechanical interplay of compression and tension through bones, joints, cartilage, fascia and ligaments. Weight-bearing through congruent joints, and the way those joints transmit and distribute load, is central to stability.

While the elastic properties of connective tissue contribute to the quality of uprightness, they work in concert with active neuromuscular control and sensory feedback from the vestibular, visual and proprioceptive systems.
Uprightness is not fixed or rigid. It is a living process that changes and adapts. Our control comes from how we organise ourselves to meet the pull of gravity, not from any built‑in support that gravity gives us.

Comparing the two models of uprightness.

The conventional model recognises that uprightness requires active work: postural muscles must generate tone, joints must bear and transmit load, and the nervous system must constantly adjust to maintain balance. Its weakness is that it often equates “active” with “hard work”, leading to over‑effort, bracing, and unnecessary compression.
The elastic uprightness model, at its best, reminds us that upright coordination can have a quality of ease, adaptability, and spring , but if taken literally, it risks implying that posture is a passive suspension, downplaying the role of active neuromuscular control and skeletal load‑bearing.

An Alexander Technique‑informed synthesis would:

•  Accept the mechanical reality that uprightness depends on the interplay of compression and tension through bones, joints, cartilage, fascia and ligaments, under constant neural regulation.

•  Retain the experiential insight that this can be organised with minimal excess effort, so that tone is appropriate to the task and context.

•  Use inhibition to prevent the reflexive over‑recruitment of muscles associated with “holding oneself up”.

•  Use direction to invite length, width and adaptability, so the active work of uprightness is distributed efficiently through the whole system.

In this integrated model, “effort” is not eliminated, it is right‑sized. The body is actively engaged in weight‑bearing and balance, but without the surplus tension that distorts coordination. Uprightness becomes a dynamic, adaptive process in which the necessary work is done with the least interference, and the quality of ease is the by‑product of efficient organisation, not the absence of muscular activity.
