Why Gemini 12 added restraints

On Gemini 12, Aldrin installed a handbar and unfolded a handrail before his main spacewalk. During that EVA, he used waist tethers and foot restraints to hold himself at work stations while he connected and disconnected electrical and fluid fittings, tightened bolts, and tried other representative tasks. Staying positioned mattered because it freed his hands to work rather than continually using them to steady himself^[1][2].

The chronology calls the complex EVA successful and says Aldrin’s condition was monitored so he could be advised to rest before fatigue developed. It does not state that twelve mobility aids were added, that eight had never flown, or the requested report finding about feasibility and workload in those terms, so those claims cannot be attributed to this text^[3].
