Fig 2.
Quickness (time to completion).
Differences in task completion times between sessions in median and quartile box plot. Blue boxes indicate medians below zero, or improved quickness, red boxes indicate medians above zero, or decreased quickness. X axis ticks indicate JHFT task number (2, 4, and 7) and tBBT.
Fig 3.
Difference in normalized jerk between sessions summarized as a boxplot for (A) left shoulder joint, (B) right shoulder joint, (C) right elbow joint, and (D) torso. Blue boxes indicate medians below zero, or improved smoothness, red boxes indicate medians above zero, or decreased smoothness. X axis ticks indicate JHFT task number (2, 4, and 7) and tBBT.
Fig 4.
Difference in path length between sessions summarized as a boxplot for (A) left shoulder joint, (B) right shoulder joint, (C) right elbow joint, and (D) torso. Blue boxes indicate medians below zero, or improved efficiency, red boxes indicate medians above zero, or decreased efficiency. X axis ticks indicate JHFT task number (2, 4, and 7) and tBBT.
Fig 5.
Range of motion difference in range of motion between sessions summarized as a boxplot for (A) left shoulder joint, (B) right shoulder joint, (C) right elbow joint, and (D) torso.
Blue boxes indicate medians below zero, or decreasing ROM, red boxes indicate medians above zero, or increasing ROM. X axis ticks indicate JHFT task number (2, 4, and 7) and tBBT.
Fig 6.
Difference in maximum angle between sessions summarized as a boxplot for (A) left shoulder joint, (B) right shoulder joint, (C) right elbow joint, and (D) torso. Blue boxes indicate medians below zero, or decreasing maximum angles, red boxes indicate medians above zero, or increasing maximum angles. X axis ticks indicate JHFT task number (2, 4, and 7) and tBBT.
Fig 7.
Difference in average moment between sessions summarized as a boxplot for (A) left shoulder joint, (B) right shoulder joint, and (C) right elbow joint. Blue boxes indicate medians below zero, or reduced effort, red boxes indicate medians above zero, or increased effort. X axis ticks indicate JHFT task number (2, 4, and 7) and tBBT.
