Researchers at the Instituto Politรฉcnico de Setรบbal used ๐๐ด๐ฆ๐ฏ๐ด ๐๐ธ๐ช๐ฏ๐ฅ๐ข to look inside the dart throw: what the arm does, and how the dominant and non-dominant hand compare.

12 young adults, including one left-handed man and one left-handed woman, threw 18 darts with each hand at a target 2.37 m away. The goal: score as many points as possible.

Eight wireless Xsens Awinda sensors on the hand, forearm, upper arm and shoulder of both arms recorded every throw at 100 Hz. The setup didn't restrict how participants moved their arms, so the throws stayed close to real play. The team tracked the rotation, speed and acceleration of each arm segment, how long each throw took, and how steady the shoulders stayed.

- Most participants scored higher and threw faster with their dominant hand.
- The hand showed the most movement and the shoulder the least, acting as the stable base of the throw.
- The left-handed woman performed most evenly between hands (40 vs. 31 points).
- The left-handed man had the shortest throw times and the steadiest posture.

Measuring shoulder stability, speed, acceleration and timing works well beyond darts. The same approach applies to precision sports like tennis, baseball and archery, and can support real-time feedback on coordination, consistency and injury prevention.
