The Method
The Functional Capacity Index combines three measurement channels into one weekly figure. It measures function — not symptoms, not mood, not diagnoses.
The three channels
Attentional capacity
A short weekly performance test in the browser, built on established paradigms from attention and vigilance research. What is measured is not whether someone can solve a task, but how stable performance remains over the duration of the test.
Day structure & recovery
The regularity of sleep timing and subjective recovery, reported each morning in a brief sleep block. The primary measure is night-to-night variability of the sleep midpoint; assessment follows the Sleep Regularity Index, whose founding computation used daily sleep diaries (Phillips et al. 2017). Watch data, optionally uploaded once a week, enrich the layer with passive rest-activity measures — without a sensor these are recorded as not measured, never estimated. No step counts, no location data, no content of any kind.
Intention and follow-through
A brief intention question in the morning, a brief execution question in the evening. The gap between what was planned and what was done is a functional signal in its own right — captured in under a minute per entry.
The weekly report
The result is one page per week: the FCI with a trajectory arrow, the sub-trajectories, data quality, and one plain-language sentence. The report is deliberately built to be readable in a case conference without explanation.
The physician's authority
Every step in reintegration requires two things: a stable data picture and the approval of the treating physician. The data informs; the decision remains medical. The report goes to the insured person first. They decide who else receives it, and can revoke each release separately.
The Dynergia Method is care-management decision support anchored in the treating physician's authority. It informs reintegration decisions with objective longitudinal functional data; it does not adjudicate work capacity and does not prescribe treatment.
What the FCI is not
The FCI makes no diagnoses, prescribes no treatment, does not assess work capacity, and is not a surveillance instrument. It replaces neither medical judgement nor the conversation — it gives both a shared, continuous data foundation.
Compared only with oneself
All values are standardised exclusively against the person’s own baseline from the first weeks. There are no norm tables, no comparisons between individuals, no thresholds to be "passed".
