Characteristics of torque generation before and after transfer. Details of the characteristics of center of pressure (COP) and load force (LF) difference in the pre- and post-transfer lifts. The 4 context switch conditions of the study are shown: (1) adding effectors (unimanual to bimanual) for an object with a left center of mass, (2) adding effectors (unimanual to bimanual) for an object with a right center of mass, (3) removing effectors (bimanual to unimanual) for an object with a left center of mass, (4) removing effectors (bimanual to unimanual) for an object with a right center of mass.

Condition	Unimanual to bimanual		Bimanual to unimanual
	Pre-transfer unimanual	Post-transfer bimanual	Pre-transfer bimanual	Post-transfer unimanual
Left center of mass
Difference	Higher left side (thumb) COP	Higher left hand COP	Higher left hand COP	Higher left side (thumb) COP
	Larger right side (finger) LF	No LF difference	Larger left hand LF	Larger right side (finger) LF
COP magnitude		Smaller difference than lift 10 Partial transfer		Smaller difference than lift 10 Partial transfer
Right center of mass
Difference	Collinear COP	Higher right hand COP	Higher right hand COP	Higher left side (thumb) COP
	Larger right side (finger) LF	No LF difference	Larger right hand LF	Larger right side (finger) LF
COP magnitude		Smaller difference than lift 10 Partial transfer		Larger difference than lift 10 No transfer
