Function
A person may develop an assistive mobility strategy through lived function rather than a conventional device pathway.
MOTIVATING CASE · BOUNDED EXAMPLE
Inline skates as a non-standard mobility aid
This case motivates a general protocol. It does not make inline skates the rule, establish a universal device classification, or replace setting-specific evaluation.
What the case illustrates
Function can emerge before a familiar device pathway exists.
A functional adaptation developed outside a conventional prescription path. Historical documentation preceded modern instrumentation, and optional modern evidence later supported review of present-day function without becoming a prerequisite.
Environment
Different institutions can reach different scoped decisions because the relevant setting and hazard profile differ.
Documentation
Prior documentation and optional evidence can inform review without converting one person’s record into a universal rule.
Standards lesson
Evaluate function, environment, risk, conditions, and the documented decision.
The case supports a general inquiry: what function does the aid provide, what is the actual environment, what specific risk is supported, what conditions may address it, and what decision should be documented?
Case-derived evidence · through October 10, 2026
Measure the person’s function in the setting that matters.
Troy’s N-of-1 record brings together repeated walking and skating comparisons, transportation measurements, four prospective service days, and longitudinal heart-rate observations. It illustrates why a proposed review should consider function and evidence alongside the environment, actual risk, reasonable mitigation or operating conditions, bounded reassessment, and portable recognition of prior scoped decisions. The case does not decide what every institution must allow.
Read the lay-reader evidence brief or public evidence and source detail. Later observations remain supplemental to this cutoff.
Boundary
What this case study does not provide.
It does not reproduce private medical records, personal HR/HRV graphs, a complete personal chronology, or a generalized legal conclusion. Those materials remain separated by purpose and source status.
