This study examined the subjectivity of forces applied by 10 testers during simulated manual-muscle testing. Individual testers were able to modify appropriately the forces they applied for muscle test grades of 3+, 4-, and 4, that is, the forces rose concomitantly with the grades. Testers were consistent between trials in the forces they applied for each grade while testing each specific action. They varied, however, in the forces they applied for each grade during the testing of the two different muscle actions. Moreover, testers differed significantly from one another in the forces they applied for each manual muscle test grade (3+, 4-, and 4). If an individual's strength is to be monitored using manual-muscle testing, grades obtained by a single tester are recommended.
本研究调查了10名测试者在模拟徒手肌力测试过程中施加力量的主观性。对于3+、4-和4级的肌肉测试，个体测试者能够适当地调整他们施加的力量，也就是说，力量随着等级的升高而增加。在测试每个特定动作时，测试者在每次测试同一等级时所施加的力量在各次试验之间是一致的。然而，在测试两种不同的肌肉动作时，他们在每个等级所施加的力量有所不同。此外，在每个徒手肌力测试等级（3+、4-和4）上，测试者之间施加的力量存在显著差异。如果要通过徒手肌力测试监测个体的力量，建议由单一测试者给出等级评定。
