PURPOSE:The main objective of this study was to determine the reliability and concurrent validity of using Modified Sphygmomanometer (sphyg) and body weighing scale to determine the magnitude of pressure and body weight change during digital spinal examination. SUBJECTS:One hundred and twenty apparently healthy subjects were recruited. METHODS:Weighing scale was used to measure the body weight of the investigator while Mercury sphygmomanometer was used to measure the pressure exerted. There was test re-test interval of 2 weeks. Data were analysed by descriptive statistic and Pearson product moment correlation. RESULTS:The result showed that there was significant correlation between the weight change (WC) values obtained on the weighing scale on day 1 and 2 (r=0.91). Also, there was significant correlation between Pressure obtained in the sphygmomanometer on day 1 and 2 (r=0.94). Similarly, there was significant correlation between the WC and Pressure Change (PC), (r=-0.49). The participant's age, height, weight and BMI contributed significantly as predictors for both BWC and PC change respectively. CONCLUSION:This study concluded that weighing scale and Mercury sphygmomanometer are reliable and valid to determine the magnitude of pressure applied during DPAP.

目的:本研究的主要目的是确定使用改良血压计和体重计确定数字化脊柱检查过程中压力和体重变化幅度的可靠性和同时有效性。
受试者:招募了一百二十名看起来健康的受试者。
方法:用体重计测量研究者的体重,用水银血压计测量施加的压力。重新测试间隔为2周。通过描述性统计和皮尔逊乘积矩相关性分析数据。
结果:结果表明,第1天和第2天在体重秤上获得的体重变化(WC)值之间存在显着相关性(r = 0.91)。同样,第1天和第2天在血压计中获得的压力之间也存在显着相关性(r = 0.94)。同样,WC和压力变化(PC)之间也存在显着相关性(r = -0.49)。参与者的年龄,身高,体重和BMI分别是BWC和PC改变的预测指标。
结论:本研究得出结论,称重秤和水银血压计对于确定DPAP期间施加的压力大小是可靠且有效的。
