Leo's Pad features the adventures of a young Leonardo da Vinci, his pet dragon, and friends Galileo and Marie, and has children doing puzzles (to build telescopes and rocket ships, e.g)., flying through clouds, identifying colors and shapes, drawing, finding letters in the stars, and much more.
He thinks he has grown too comfortable with drawing, finding himself in a loop of drawing things that have worked well in the past.
Also, patients with no MRI-visible nerve involvement lacked a grade 2 positive physical examination/pain drawing finding significantly more often than a grade 1.
The mean positive and negative predictive values for MRI-visible nerve involvement at any location in segments T11-S1 respectively decreased and increased significantly for all tests of grade 2. This means that MRI-visible nerve involvement was significantly less often confirmed as a grade 2 than a grade 1 positive physical examination/pain drawing finding.
This means that about 1/3 to 1/4 of those having no physical examination or pain drawing finding indicating nerve involvement in segment L4-5 were considered as having MRI-visible nerve involvement in segment L4-5.

McNemar's test showed significant differences between MRI and pain drawing findings of nerve involvement in segments L4-5 and L5-S1.
McNemar's test showed a significant difference between MRI and physical examination/pain drawing findings of nerve involvement in less than 20% of all locations.
MRI-visible nerve involvement was significantly less common than, and showed weak agreement with, physical examination and pain drawing findings of nerve involvement in corresponding body segments.
MRI, physical examination and pain drawing findings of grade 2 (or more) were significantly less prevalent than findings of grade 1 except for medulla cord signal and bone protuberance.
The mean specificity for MRI-visible nerve involvement to the absence of physical examination and/or pain drawing findings of nerve involvement at any location in segments T11-S1 ranged from 85-92%.
Sensitivity was lower in the upper segments and higher in segment L4-5 (anyany location), where 16-37% of the positive physical examination/pain drawing findings were considered as MRI-visible nerve involvement.
