However, the normal physiological range of translation and the factors influencing it remain poorly defined, limiting the test's diagnostic precision. This study aimed to quantify the normal range of DRUJ translation and identify its associated factors in a healthy population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Healthy adult participants were recruited between January 1, 2025, and April 30, 2025. Data on occupation, gender, age, height, weight, handedness, wrist circumference, forearm length, and grip strength were recorded. A custom\u2010designed device was used to measure the palmar, dorsal, and combined DRUJ translations in forearm pronation, supination, and neutral positions. Univariate and multivariate analyses were performed to identify factors influencing translation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean (\u00b1SD) combined DRUJ translation was 11.9\u2009\u00b1\u20094.2\u2009mm in pronation, 12.4\u2009\u00b1\u20093.9\u2009mm in supination, and 13.3\u2009\u00b1\u20094.6\u2009mm in the neutral position. Significant side\u2010to\u2010side differences were observed for all translations in pronation and for both palmar and dorsal translations in the neutral position. No significant side\u2010to\u2010side difference was found in supination. Compared to pronation and supination, combined and palmar translations were significantly greater in the neutral position. Conversely, dorsal translation was greatest in supination. Multivariate analysis revealed that combined DRUJ translation in supination was significantly influenced by grip strength, forearm length, weight, and age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our findings establish reference values for DRUJ translation and demonstrate that it is influenced by forearm position and multiple factors. To improve the clinical utility of the ballottement test, we recommend performing it in forearm supination while comparing both limbs. Specifically, combined DRUJ translation with forearm supinated is significantly affected by grip strength, forearm length, weight, and age.<\/jats:p>\n                  <\/jats:sec>\n
