FUNCTION BEFORE APPEARANCE

Evaluate the mobility function—not the familiar category.

A proposed protocol for reviewing unfamiliar disability-related mobility aids through function, operation, environment, actual risk, feasible conditions, and a documented decision.

Why this standard exists

Unfamiliar does not answer the functional question.

Unfamiliar mobility aids can be rejected by category before their actual function, environmental fit, risks, or workable operating conditions are evaluated. A label alone does not establish what an aid enables, how it is operated, or what risk exists in a particular setting.

Skates used for mobility are the motivating case. This proposed protocol is designed to generalize beyond skates.

A non-standard mobility aid is a device, configuration, or practiced adaptation used to address a disability-related mobility function that falls outside an institution’s familiar device taxonomy or ordinary accommodation workflow.

It is an evaluation category. It is not automatically a legal classification, diagnosis, entitlement, permit, or universal authorization.

The method

Eight stages, one scoped review.

Start with mobility function. Then evaluate the device or adaptation, user proficiency, evidence, environment, actual risk, feasible mitigation, and the resulting documented decision.

Two review paths

Recognized category or functional inquiry.

A familiar device may enter an ordinary process. An unfamiliar disability-related aid requires a functional inquiry; neither path predetermines the outcome.

Familiar vs. unfamiliar device path

Familiar deviceRecognized category → ordinary process
Unfamiliar aidFunctional inquiry → individualized review → conditions where appropriate → documented decision
Text equivalent: familiar devices may use an ordinary process; unfamiliar disability-related aids receive a function-first, individualized review with conditions where appropriate and a documented decision.

The output

A documented, scoped decision.

A review should retain the request, setting, evidence considered, risks identified, mitigation considered, decision, conditions, scope, and reassessment trigger. The result is reviewable rather than disappearing into undocumented front-line discretion.

Portable Mobility Record

The proposed Portable Non-Standard Mobility Aid Record is a voluntary way to preserve functional facts and prior scoped decisions where appropriate.

Privacy by design

Use the minimum necessary functional information. Supporting medical and wearable records should ordinarily remain separately controlled.

Function is not always visible

Appearance is not a pain meter.

Pain is reported by the person, not read from appearance or a sensor. Functional limitation may require individualized evaluation even when it is not visible. Objective evidence can help describe movement, exposure, or mobility output, but it is not a pain meter and should not be required in every case.

Motivating case

Inline skates are one reason this protocol exists.

A bounded case study shows how a functional adaptation can emerge outside a conventional prescription path, receive different scoped decisions in different settings, and later be supported by optional evidence.
