intermediate work · DEXA clinic (or calibrated BIA), Bethesda, MD

DEXA appendicular lean mass (sarcopenia quantity) — Bethesda.

Fund it for $480. Proof lands onchain when it's done.

$480 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

What the work involves

Bethesda, MD is home to the National Institutes of Health, where the FNIH Sarcopenia Project's NIA-affiliated investigators built the US pooled-cohort consortium behind one of this standard's two frameworks: Studenski SA, Peters KW, Alley DE, et al. J Gerontol A Biol Sci Med Sci. 2014;69(5):547-558 -- 26,625 participants pooled across 9 studies, defining low lean mass as appendicular lean mass/BMI below 0.789 (men) or 0.512 (women). Muscle quantity is the organ reserve of aging, lost silently -- a DEXA scan gives the true number, offered where the US-relevant consensus threshold was built.

Proof
DEXA (or calibrated BIA) appendicular lean mass with the ALMI (or ALM/BMI, framework noted) compared to the stated consensus threshold, plus the scan report

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

  • DEXA scan appointment (or calibrated multi-frequency BIA)
  • height measure
  • scan/report printout

Steps

  1. 1. Arrange a DEXA body-composition scan (preferred) or a calibrated BIA under standardized hydration.
  2. 2. Record appendicular lean mass (arms + legs, kg) and height (m).
  3. 3. Compute ALMI = appendicular lean mass / height^2 (kg/m^2).
  4. 4. Compare ALMI to EWGSOP2/FNIH low-muscle thresholds; note the method used.
  5. 5. Attach the scan report; log ALM, ALMI, and method; sign it.

What counts as done

  • Appendicular lean mass (kg), height, and BMI, with both ALMI (kg/m^2) and ALM/BMI computed
  • Method noted (DEXA preferred; BIA flagged as a proxy)
  • Result compared against ONE named framework's threshold (EWGSOP2 ASM/height^2 or FNIH ALM/BMI), never blurring the two into a single number

Proof is measured against these, not judged by taste.

The money and the proof

What is promised, and what is not.

Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788267617276_pgm27b5","funderWallet":"0xYOU"}.

An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
