Assistive Technology & Organismic Life

Not “is a wheelchair part of the body?” That has no single correct answer. Instead: where does embodiment end?

Where the classical language falls short

Biodynamic theory’s “organism” language, inherited from Reich, tends to picture a self-contained biological system — vital, self-regulating, complete on its own terms. For a person whose actual, lived body includes a wheelchair, prosthetic, ventilator, or communication device, that language can implicitly exclude the very things that make their embodied life work.

Where does embodiment end?

For one person a wheelchair may feel like part of their body. For another it may feel like a tool. For another it may feel like freedom, or like inconvenience, or like all of these depending on the day. The theory must not decide this in advance. Assistive technology does not need to be experienced as part of the self in order to be respected as part of embodied life. Both positions deserve the same respect, and so does changing between them.

Beyond wheelchairs

This question extends well past mobility devices: AAC devices, prostheses, orthoses, hearing aids, ventilation, feeding technology, standing equipment, hoists, smart-home controls, catheters, and communication technology all raise the same problem. Not because they are all psychologically equivalent to one another, but because they all expose the same fiction — that of the biologically self-contained organism. Humans regulate through environments and technologies all the time; disability simply makes that fact impossible to ignore.

You might recognise this

“My chair feels like part of how I move through the world.” “My device is a tool. I don’t experience it as part of me.” “When somebody moves my wheelchair without asking, it feels different from moving a normal object.” “My communication device doesn’t make my communication less mine.” “Technology gives me more bodily choice, not less embodiment.”

A lived scene · fictional teaching example

A therapist, working from a classical organismic model, invites a client to notice sensation moving through “the body,” unconsciously picturing skin as the boundary. The client uses a communication device and breathing support. When the therapist later asks what she noticed in her body during a difficult moment, she says, “my device slowed down, the same way my voice would have caught.” The therapist has a choice: treat that as a strange aside, or recognise it as exactly the kind of embodied information the exercise was looking for, arriving through a channel the original theory didn’t anticipate.

A process: Notice → Ask → Include → Adapt → Respect

Notice: how the person actually uses the device, without assuming.
Ask: what relationship they have with it — tool, extension, both, neither, it depends.
Include: the device in the therapy space and the formulation, rather than working around it.
Adapt: interventions around the actual body-device system present, not an imagined body without it.
Respect: that the person determines its meaning, and that this can change.

A question worth carrying

Does this theory’s picture of “the organism” actually include my whole lived body — equipment and all — or does it quietly stop at skin?
