Summary of reports on the assessment of performance deficits when using objects in stroke patients. LBD: left brain damage.

Reference	Objects used	Result	Type of scoring
Liepmann [8]	Comb, brush, hammer	Errors in 25% of “dyspraxics” (N=42)	Right or wrong
De Renzi and Luchelli [36]	Common-use objects	All of them made errors	Major or minor or no error
McDonald et al [37]	Cup, key, fan, scissors	17 LBD patients: no differentiation from other task modes	Right or wrong
Buxbaum et al [38]	Common-use objects	Single case: fewer errors during use	Grasp, trajectory, amplitude, and timing
Westwood et al [39]	Hammer, saw, spectacles	Object use deficit: 37 LBD patients (43%); 50 right brain damage patients (18%)	Performance accuracy from composite scores
Goldenberg et al [40]	Glass, apple, electric bulb, squeezer	10 LBD patients: more errors in the use of actual tools	The presence of feature for grasping and movement
Randerath et al [41]	Hammer, ladle	25 LBD patients: errors in almost all conditions	The presence of features: grasp, movement execution, direction, space
