To evaluate the relationship between posture and psychomotor efficiency, 20 anesthesia providers performed a test requiring manual dexterity and eye-hand coordination while seated, kneeling, and standing bent forward at the waist. Performance on the Grooved Pegboard Test improved 6%-10% (P < 0.005) when subjects were seated compared to kneeling and standing bent at the waist, positions that the subjects rated as more painful and less comfortable than sitting. Sitting improved manual dexterity more in subjects with poor scores than it did in subjects with good performance. This study demonstrates improved manual dexterity in subjects seated in a comfortable position.
为评估姿势与精神运动效率之间的关系，20名麻醉医护人员在坐着、跪着以及弯腰站立时进行了一项需要手部灵活性和眼手协调能力的测试。与跪着和弯腰站立相比，受试者坐着时在有槽钉板测试中的表现提高了6%-10%（P<0.005），而受试者认为跪着和弯腰站立比坐着更疼痛、更不舒服。在得分较低的受试者中，坐着比表现良好的受试者更能提高手部灵活性。这项研究表明，处于舒适坐姿的受试者手部灵活性有所提高。
