TAM: anyone with meaningful hand recovery, pain, function, or performance needs (acute, post-op, chronic, workplace, aging).
Directional burden heuristic: ~2.6M annual U.S. hand/wrist ED injuries × ~$7K median total cost ≈ ~US $18B acute burden (methods differ; illustrative only).
SAM: people actively trying to recover, track, or communicate progress.
SOM (first wedge): post-injury and post-surgery users searching for help at home — urgency, intent, timelines, and weekly summaries matter immediately.
