Evidence corpus

Evidence Corpus

This page organizes the public HandicapSkater evidence corpus: wearable physiology, HR, HRV/RMSSD, RRI, ACC motion exposure, route records, movement cohorts, transportation burden, and source-linked review artifacts.

Public source-linked evidence supporting the HandicapSkater mobility-aid record.

The evidence corpus does not directly measure pain, diagnose a condition, or decide legal entitlement. It supports within-person review of mobility burden across walking, skating, transportation, and recovery context.

What the corpus contains

The Evidence Corpus separates source-linked evidence by role so reviewers can see what each stream contributes.

Wearable physiology

HR, HRV/RMSSD, RRI, recovery context, and longitudinal physiology signals.

Motion exposure

ACC, vibration, impact, jerk, and shock components used to review movement burden.

Route context

GPS route maps, distance, time, weather context, and repeated mobility records.

Movement cohorts

Walking, skating, ParaTransit, motorcycle, wheelchair, and recovery contexts.

Legal review context

Source-linked records, exhibits, review artifacts, and access-history references.

FSI review layer

Fractal Stability Index uses a Cohort Similarity Score (CSS) to organize burden and cohort comparison evidence.

Current Corpus Model

The refined corpus contains 2,171 records. Body coupling context exists for all records. Physiologic efficiency exists for all records. RAG facets are expanded. Eighty one records have ACC shock component metrics. The impact shock index remains components only because no normalization baseline is defined.

Walking median HR is 130 bpm, PT skating median HR is 113 bpm, and mall skating median HR is 78.6 bpm. Walking duration median is 40 min, mall skating duration median is 33.7 min, and PT skating duration median is 143.5 min. Walking versus mall skating is the cleanest duration comparable physiologic contrast. PT skating supports longer tolerated activity at lower HR than walking.

Active ballistic median HR is 130 bpm, active controlled median HR is 109 bpm, passive passenger median HR is 88 bpm, and recovery baseline median HR is 53.1 bpm. Controlled walking versus PT skating subset still needs manual audit.

Physiologic burden

HR, RMSSD, recovery context, HR per mile, distance per mean HR, duration tolerated, and RMSSD deltas when available.

Mechanical motion exposure

ACC dynamic RMS, jerk RMS, shock spike rate, and cumulative dynamic shock. These quantify motion exposure at the sensor, not pain by themselves.

Body coupling and control

Active controlled, active ballistic, passive passenger, and recovery baseline describe how the body is coupled to the activity or vehicle.

Longitudinal + episodic evidence

Mobility Science Corpus

The current public corpus keeps historical WHOOP and Strava mobility-pattern evidence distinct from episodic Kubios / Polar H10 session evidence, then merges both layers for reviewer-safe summaries. WHOOP recovery HRV is daily recovery context, not session-level Kubios HRV.

Longitudinal context

WHOOP + Strava

Historical WHOOP and Strava records preserve activity patterns across skating, walking, ParaTransit, motorcycle, recovery, and other mobility contexts before Kubios was available.

Episodic sensors

Kubios / Polar H10

Kubios adds session-level RRI, RMSSD, ECG, and ACC detail where available. It is the higher-specificity episodic layer for same-day and activity-specific comparisons.

Merged review

FSI Evidence Observatory

FSI is the Fractal Stability Index. CSS is the Cohort Similarity Score layer used to strengthen cohort comparison without redefining FSI.

Longitudinal cohort summary

These rows summarize the historical WHOOP/Strava mobility-pattern layer. They do not invent Kubios shock metrics for historical records.

Source-indexed, validation-tested, audit-ready

Generated Evidence Snapshot

Source-indexed wearable and movement evidence comparing walking, skating, transport, and baseline cohorts.

These scores do not measure pain directly and do not make clinical or legal conclusions. They summarize within-person MSK burden patterns from wearable, movement, and source-indexed evidence.

FSI Tensor Burden

What the body absorbs across physiology, mechanical shock, MSK load path, passive exposure, active control, and functional output.

Impact Burden Proxy

Shock interpreted through physiology and MSK load path. This is not a direct pain measurement.

Functional Mobility Efficiency

Useful mobility produced for the burden. This separates "hard" from "useful."

Key Findings

Concise findings are generated from the current public review JSON values.

  • Mall skating constitutes using skates around the mall limiting the ballistic component by not lifting the leg, but minute side-to-side movement to preserve momentum.
  • PT skating constitutes using skates with a minimal ballistic component, stepping lightly, for preservation of momentum.

Cohort Ranking

Cohorts are sorted ascending by FSI Tensor v0.3 burden score.

Validation and Audit Checks

These checks test whether the model survives common criticisms: hand-picked weights, small samples, one unusual session, unclear functional output, weak cohort separation, and missing audit linkage.

Source and Reproducibility

The public snapshot is generated from the FSI Evidence Observatory. CSS enhances cohort comparison through Comparable Similarity Score outputs. Full formulas, session outputs, source indexes, and hashes remain in the evidence platform artifacts.

These scores do not measure pain directly and do not make clinical or legal conclusions. They summarize within-person MSK burden patterns from wearable, movement, and source-indexed evidence.

Why this evidence corpus exists

I built this evidence corpus to show the functional difference between high burden walking, adaptive skating, motorcycle travel, skates as a wheelchair labeled use, ParaTransit, commuting, and other mobility contexts.

The goal is simple: make invisible mobility burden reviewable.

Burden

Walking can impose higher burden

For my pelvic/SI/hip disability, walking can be associated with higher physiologic and functional burden even when distance is short.

Function

Skating can preserve mobility

Inline skates support smoother, more horizontal movement and may reduce the repeated impact pattern that makes walking difficult in this within person record.

Access

Forced alternatives can increase burden

When public systems deny skates, the alternatives can include high burden walking, unstable ParaTransit rides, or unnecessary wheelchair use.

What the Evidence Shows

The Evidence Corpus is the public evidence layer. It connects skating as a lower burden mobility aid, walking and ParaTransit burden, wearable HR/HRV evidence, FSI/CSS metrics, physiologic burden context, and accommodation relevance.

Record facts

Mobility modes differ

The dashboard organizes walking, skating, skates used as a wheelchair labeled use, motorcycle travel, ParaTransit, commuting, and related cohorts as distinct mobility contexts.

Interpretation

Within person burden matters

The useful signal is not HR or HRV alone. It is the within person pattern across HR, HRV/RMSSD, raw beat-to-beat interval data (RRI) quality, duration, mobility mode, distance, recovery, and mechanical exposure.

Efficiency

Functional Mobility Efficiency

Distance is mobility achieved, not automatic burden. Functional Mobility Efficiency asks how much useful mobility is achieved per unit of physiological and mechanical exposure.

ParaTransit burden is part of the mobility evidence

Functional Mobility Efficiency applies to transportation as well as ambulation. A ParaTransit ride should not be judged only by whether a vehicle arrived. It should be reviewed by the access achieved and the physiologic, mechanical exposure, posture, motion, and duration burden imposed.

The ParaTransit Burden page explains why cutaway buses, vans, back seat shared sedans, SilverRide/front seat service, rail, and direct routing are not functionally equivalent for my documented pelvic/SI/hip disability.

Review ParaTransit Burden

Source-linked FSI case study results

The current FSI work treats Kubios/Polar H10 as the activity specific biomechanics stream, WHOOP as longitudinal physiology context, and Strava as functional distance and route capacity context. The results are source linked decision support evidence for accommodation evaluation; they do not independently decide pain or legal entitlement.

Skating vs walking

Dynamic burden

FSI compares dynamic burden instability using features such as vertical dynamic ratio, movement variability, peaks per minute, and impact shock. Long skating distance is treated as functional capacity unless paired with high impact, high physiologic burden, or low activity specific HRV.

Sedan vs bus/cutaway/van

Passive mechanical burden

Vehicle comparisons emphasize vertical RMS, peak absolute acceleration, peak-to-peak motion, jerk, movement standard deviation, and cumulative impact shock. SilverRide/front seat/direct service is the current lower burden transportation reference. Generic sedan service should not be treated as automatically effective when it is back seat-only, shared, prolonged, posture-constraining, or mechanically harsh.

Evidence hierarchy

Kubios first, context preserved

Kubios/H10 provides the highest specificity for per-activity HRV/RRI and accelerometer burden. WHOOP and Strava corroborate longitudinal heart-rate patterns, recovery context, distance, duration, and functional mobility capacity.

Walking can impose burden. Skating can preserve mobility.

Wearable and activity data compare high burden walking, adaptive skating, motorcycle travel, wheelchair labeled use, ParaTransit, commuting, and forced alternatives.

The embedded Tableau Public workbook is a visual evidence summary. Use it to compare activity cohorts, distance, duration, heart-rate burden, and recovery signals. If the embed does not load, open the public dashboard directly.

How to read this evidence corpus

Start by comparing walking and skating. Distance alone does not tell the story. The key question is how much physiologic and mechanical exposure is required to move.

A short high burden walk can impose more burden than a longer skate because skating changes the mechanics of movement. A 2 mile skate and a several hundred foot walk should be compared by functional mobility achieved per burden unit, not by distance alone.

Distance: functional mobility achieved.
Duration: how long the burden lasts.
Heart rate: cardiovascular load during movement, transit, or forced alternatives.
HR zones: time spent in higher exertion or stress zones.
HRV/RMSSD: autonomic regulation where available, not standalone pain proof.
Activity category: skating, walking, wheelchair labeled use, motorcycle, ParaTransit, commuting, and related cohorts.
Movement pattern: vertical versus horizontal dynamics where available.
FSI: Fractal Stability Index, a proposed stability-pattern metric.
CSS: Comparable Similarity Score, a proposed similarity-to-reference framework.

Key findings

The corpus is evidence, not a standalone medical or legal ruling. The pattern matters because mobility aids should be evaluated by function, not appearance.

  • Skating supports longer functional mobility with a more sustainable burden pattern.
  • Walking can produce disproportionate physiological burden relative to distance.
  • ParaTransit and forced alternatives may create passive stress, especially when rides are long, unstable, shared, or mechanically harsh.
  • Distance should be treated as functional output, not burden by itself.
  • The data supports individualized review of mobility aids by function, not appearance.
  • This is a real world wearable health AI case study and accommodation evidence layer.

Why this matters to wearable health and mobility-intelligence teams

Most wearables count activity. This project asks a harder question: is the movement lower burden, higher burden, accessible, or forced?

HandicapSkater.com is the research and product development layer for wearable mobility evidence, activity label reconciliation, assistive mobility analytics, and privacy preserving evidence summaries.

HandicapSkater.org is positioned as the standards and civil-rights framework that can translate evidence into fair access language.

Beyond step counting

A disabled person may need fewer steps, not more. The metric should be functional mobility, not conformity to walking.

Adaptive mobility analytics

The evidence corpus compares skating, walking, motorcycle travel, wheelchair labeled use, ParaTransit, and commuting as different mobility cohorts.

Human-centered AI

The project combines wearable data, biomechanics, legal context, and lived experience to show platform potential for disability aware AI without claiming any current platform partnership.
