| description | Purpose: To evaluate the reproducibility and the accuracy of our technique to measure the range of dart-throwing motion. Methods: Two raters measured the range of dart-throwing motion of 42 healthy participants. The participants performed a simulated hammering action with a wooden mallet, and the inclination angle of the mallet on the vertical plane was measured using an attached bubble inclinometer at the maximal position of radial extension and ulnar flexion. The sum of these angles was defined as the range of the dart-throwing motion. Each rater performed three measurement trials for each participant. To determine inter-rater reproducibility, intra-class correlation coefficients were calculated for the value of one trial, mean value of two trials, and mean value of three trials. In the first test session, wrist kinematics during measurement was recorded simultaneously using a three-dimensional optical motion capture system. Results: Intra-class correlation coefficients for the dominant and nondominant sides ranged from 0.67 to 0.75 and 0.68 to 0.79, respectively. The reproducibility of the measurements was improved by adopting the mean value as the number of repetitions of the measurements increased. Bland–Altman analysis revealed that our measurement contained a proportional bias of 30.7% to 35.9% compared with the values of the motion capture analysis as the gold standard. Conclusions: The reproducibility of the measurements was either good or moderate. The revealed biases can provide valuable data for estimating the true range of wrist motion. Clinical relevance: Our technique would be useful for reliable measurement of the range of dart-throwing motion, as it is easy to perform repeated measurements. Our method avoids observer bias even by a single examiner and can be carried out with readily available materials. |
