Questione giuridica chiave
Whether the 2010 rheumatology report reliably established a revision-relevant improvement in the insured person's capacity to work.
Decisione estratta
The report was not sufficiently reliable to determine whether the medical situation had changed in a revision-relevant way.
Motivazione estratta
It failed to account for the increased need for breaks, did not adequately address contrary medical opinions and later pain findings, and did not properly investigate possible psychopathological factors; the EFL results were only of limited value because of inconsistent effort.
