Human Movement Science published research on wrist-joint position, finger muscle length, grip strength and prolonged handwriting.   The study looked at two groups – control group of 22 young adults ages 18-24 (no pain while handwriting) and 18 young adults who do experience pain while handwriting.   Each participant completed a writing task for 30 min on a computerized system which measured the wrist-joint angle and documented handwriting kinematics.
The results indicated the following:
1.  the participants from the in-pain handwriting group perceived more soreness and had a less-extended wrist joint, longer on-paper time, and slower stroke velocity compared to control group.
2.  no significant difference in handwriting speed and quality was recorded between the two groups.
