Handgrip dynamometry + percentile — New Orleans.

Grip strength is a fast, cheap whole-body strength proxy: each ~5 kg lower grip tracks ~16% higher all-cause mortality, and low grip flags probable sarcopenia. Most people never measure it, so muscle loss goes unnoticed until it costs independence. Since Katrina pushed New Orleans off a hospital-centered safety net and toward community health centers, CrescentCare (an FQHC since 2013, building on more than 40 years as the NO/AIDS Task Force) has grown into one of the city's largest, a real no-cost-barrier route to a supervised grip reading.

$200 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.

Proof

Three efforts per hand in the standardized seated posture + best value per hand (kg) + age/sex percentile + photo of the dynamometer readout

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

• calibrated hand dynamometer (Jamar or equivalent)
• standard chair
• recording sheet

Steps

1. 1. Seat the person, shoulder adducted, elbow flexed 90 degrees, forearm and wrist neutral (Southampton posture).
2. 2. Set the dynamometer grip to the person's hand size; demonstrate a maximal squeeze.
3. 3. Record 3 maximal efforts per hand, alternating hands, with ~15 s rest between efforts.
4. 4. Take the highest of the three per hand (kg).
5. 5. Compare the best value to the age/sex percentile table; record percentile.
6. 6. Photograph the dynamometer readout; log both hands, best values, percentile, and posture confirmation; sign it.

What counts as done

• Three maximal efforts per hand in the Southampton seated posture
• Best value per hand in kg with the age/sex percentile
• Photo of the calibrated dynamometer readout

Proof is measured against these, not judged by taste.
