Overview of the 5 Exercises of the “Bimanual Fundamentals” Curriculum.

Name	Description	Training Goal	Measured Parameter	Performance Score Range
Sort the rings	Rings need to be placed in the boxes with the corresponding color. Boxes can only be opened with the same sided instrument	Bimanual dexterity and efficiency	Task time, collisionsa, path length right, and path length left	4-12
Stretch and transfer	After looping the elastic cord around the pillars, pegs need to be transferred to the opposite site, without touching the elastic cord or each other	Bimanual dexterity	Task time, collisionsb, path length right, and path length left	4-12
Ring and rope	A rope needs to be maneuvered through rings along a path	Precision and bimanual dexterity	Task time, collisionsc, path length right, and path length left	4-12
Balance	Weights need to be put on a scale, while the scale must be kept in balance	Precision, bimanual dexterity, and stability	Task time, displacementd, path length right, path and length left	4-12
Puzzle	Puzzle pieces need to be placed in the correct spot	Precision and bimanual dexterity	Task time, path length right, and path length left	3-9

^aA collision was registered when the instrument hit the edge of the ring-collecting bins.

^bA collision was registered when a peg touched the elastic cord or another peg.

^cA collision was registered when the instrument hit a ring with force.

^dDisplacement was registered when putting a weight on the scale, while the scale was not balanced.
