Total disability based on individual unemployability pays at the 100 percent rate when service-connected conditions prevent substantially gainful work. The thresholds and the forms.

Musculoskeletal ratings run on measurements, but the painful motion rule and flare-up evidence change outcomes. What the goniometer measures and what it misses.
