Two low-cost protocol versions for validating the Energy Score in practice: a fuller version that includes grip strength, and a lighter version that removes the dynamometer requirement.
Best for clinics, research pilots, and higher-rigor follow-up. Adds a direct strength or reserve signal on top of chair-rise performance and fatigue burden.
This is the stronger version if your goal is to correlate modeled energy with an objective upper-extremity strength signal.
Best for home tracking, quick clinical pilots, or settings where a dynamometer is not available. Keeps performance and symptom burden, but drops the strength-specific measure.
This is the simplest low-cost protocol to deploy broadly, but it is slightly less objective than the full bundle. A draft upper-extremity add-on is documented on the no-grip page for analysis, but it is not part of the measured-function score yet.
A companion workflow now translates these validation measures into a stepwise intervention ladder: establish baseline, add one intervention, remeasure, and keep climbing only when observed function improves cleanly.
A separate calculator now converts either protocol into a single observed-function score that can be compared against the modeled Energy Score. It is designed as an operational tracking tool, not a validated clinical scale.
