^aSVMC: selective voluntary motor control; SVMC total: total Selective Control Assessment of the Lower Extremity (SCALE) score (maximum of 2 points per joint; total of 20 points) or Selective Control of the Upper Extremity Scale (SCUES; maximum of 3 points per joint; total of 30 points); SVMC target score: SCALE or SCUES item scores for the target joint that was practiced with the game.

^bRefers to the target joint when the ArmeoSenso system was used and to the target muscle group when the electromyography-based system was used.

^cCP: cerebral palsy.

^dGMFCS: gross motor function classification system (it standardizes the classification of gross motor function, emphasizing the trunk control and walking ability of children with cerebral palsy [32]. Level 1 means that children perform all the activities of neurologically intact children of the same age, allowing for slight limitations in speed and quality of movements. Level 5 means that children exhibit difficulties in head and trunk control in most positions or in achieving any voluntary control of movement at all).

^eSelective voluntary motor control assessed with the Selective Control Assessment of the Lower Extremity.

^fsEMG: surface electromyography.

^gMACS: manual ability classification system (it classifies how children with cerebral palsy handle objects in daily activities [33]. Level 1 means that the child can handle objects easily and successfully, whereas children at level 5 do not handle objects at all).

^hSelective voluntary motor control assessed with the Selective Control of the Upper Extremity Scale.
