The 4R1 Adjustment Adapter is an adjustment tool to be used solely for the trial fitting of lower limb prostheses. It facilitates correct static alignment and permits adjustments on the standing patient under load. The scales permit reproducible adjustments, so that the gait pattern can be optimised quickly during trial walking.

The use of the 4R1 is recommended in particular with the 743L100=110 or =230 L.A.S.A.R. Posture and the 743A160 Ottobock Transfer Apparatus.
