What specific five-year task diminished Frank Marino's physical capability leading to frozen shoulder?

Painstakingly reconstructing corrupted drum tracks for the Live at the Agora audio restoration

The roots of the debilitating frozen shoulder condition are deeply connected to the meticulous and compromising work Marino undertook while restoring the audio for the Concert DVD (Live at the Agora), which was filmed in 2010. Because the original recording was corrupted, Marino had to manually discern and reinsert every single drum strike. He described this monumental effort as consuming five years of every waking minute. This painstaking, precise, and repetitive motion, required to achieve sonic perfection in the released audio, ultimately diminished his physical capability, manifesting as adhesive capsulitis. This strenuous solitary labor proved physically ruinous, in this instance, even more so than the physical demands of touring itself.
