Manual muscle testing procedures are the subject of a force and displacement analysis. Equipment was fabricated, tested, and employed to gather force, displacement, and time data for examining muscle test parameters as practiced by applied kinesiology (A.K.) clinicians. Simple mathematical procedures are used to process the data in an effort to find potential patterns of force and displacement which would correspond to the testing of strong and weak muscles on healthy subjects. Particular attention is paid to the leading edge of the force pulses, as most clinicians report that they derive most of their assessment from the initial thrust imparted on the patient's limb. An analysis of the simple linear regression of the slope of the leading edge of a force pulse reveals that a high dx/dF is indicative of a weak muscle test result (as perceived by the tester), and a low dx/dF is indicative of a strong muscle test. Thresholds for dx/dF are determined to discriminate between inhibited and facilitated muscle test results. The data lay the groundwork for future studies that examine the objectivity of A.K. muscle testing.
徒手肌力测试程序是力与位移分析的主题。制造、测试并使用了相关设备，以收集力、位移和时间数据，用于检查应用运动学（A.K.）临床医生所采用的肌肉测试参数。运用简单的数学程序对数据进行处理，试图找出力与位移的潜在模式，这些模式将对应于对健康受试者的强弱肌肉测试。特别关注力脉冲的前沿，因为大多数临床医生报告称，他们的大部分评估来自施加在患者肢体上的初始推力。对力脉冲前沿斜率的简单线性回归分析表明，高dx/dF表明肌肉测试结果较弱（测试者的感知），而低dx/dF表明肌肉测试结果较强。确定dx/dF的阈值以区分抑制性和易化性肌肉测试结果。这些数据为未来研究应用运动学肌肉测试的客观性奠定了基础。
