Case study: Functional Capacity Assessment for Postural Orthostatic Tachycardia Syndrome (POTS).
An anonymised example of how an FCA for an adult with Postural Orthostatic Tachycardia Syndrome (POTS) documented the orthostatic intolerance, fatigue and cognitive load that drives functional limitation — and translated it into NDIS-aligned supports.
The presentation
An adult in their 20s with formally diagnosed POTS (tilt-table confirmed) and concurrent post-viral fatigue syndrome. Cannot tolerate upright activity for more than 20-30 minutes before symptom escalation (tachycardia, presyncope, cognitive slowing). Bed-bound or recumbent for 4-6 hours after each upright episode. Previous funding requests declined because POTS is poorly understood in the NDIS evidence-review context. The participant had been told by NDIA delegates that 'POTS isn't NDIS-eligible' — a misunderstanding of how disability eligibility actually works.
What the FCA documented
Orthostatic tolerance documented through structured self-monitoring (heart rate response on standing, symptom escalation timeline, time-to-recovery). COMPASS-31 anchored autonomic symptom severity. WHODAS 2.0 anchored global functional limitation. Cognitive fatigue (often missed in POTS assessments) documented through pre-and-post upright cognitive screening. Daily diary data over three weeks established the upright-tolerance ceiling and recovery cycle. We framed the eligibility question correctly: NDIS eligibility is determined by functional impact, not diagnosis.
What was recommended
- Support worker hours scheduled around upright-tolerance windows — meal preparation, shopping, transport
- Capacity Building (Improved Daily Living) — OT for energy-conservation strategies + activity pacing
- Capacity Building (Improved Health and Wellbeing) — supervised exercise programming (recumbent-progressive)
- Assistive technology — compression garments, mobility aid for upright tolerance
- Allied health input — specialist POTS-experienced exercise physiology
Why the report was defensible
The report reframed the eligibility question correctly: POTS itself is not on or off an 'NDIS list'. NDIS eligibility is determined by functional impact, and the functional impact of severe POTS is documented in the international medical literature and was anchored in this report through standardised scoring. The plan-review delegate accepted the framing and supports were approved.
