[Purpose] The purpose of the present study was to examine the validity of functional reach models by comparing actual values with estimated values. [Subjects and Methods] Twenty-eight volunteers were included in this study (male: 14, female: 14, age: 21 ± 1 years, height: 166.8 ± 9.0 cm, and body mass: 60.1 ± 8.5 kg). The maximum forward fingertip position and joint angles were measured using the original equipment. In addition, the maximum forward fingertip position, shoulder joint angle, and knee or ankle joint angle were estimated using the functional reach model. [Results] The correlation coefficients between actual data and estimated data for the maximum forward fingertip position, shoulder joint angle, and ankle joint angle while standing were 0.93, 0.83, and 0.73, respectively. The correlation coefficients between actual data and estimated data for the maximum forward fingertip position, shoulder joint angle, and knee joint angle while kneeling were 0.86, 0.81, and 0.72, respectively. [Conclusion] The validity of both functional reach models in estimating optimal posture was confirmed. Therefore, the functional reach model is useful for evaluation of postural control and optimal postural control exercises.
[目的] 本研究的目的是通过比较实际值和估计值来检验功能伸展模型的有效性。[对象与方法] 本研究纳入了28名志愿者（男性：14名，女性：14名，年龄：21±1岁，身高：166.8±9.0厘米，体重：60.1±8.5千克）。使用原始设备测量最大向前指尖位置和关节角度。此外，使用功能伸展模型估计最大向前指尖位置、肩关节角度以及膝关节或踝关节角度。[结果] 站立时最大向前指尖位置、肩关节角度和踝关节角度的实际数据与估计数据之间的相关系数分别为0.93、0.83和0.73。跪立时最大向前指尖位置、肩关节角度和膝关节角度的实际数据与估计数据之间的相关系数分别为0.86、0.81和0.72。[结论] 证实了两种功能伸展模型在估计最佳姿势方面的有效性。因此，功能伸展模型对于姿势控制和最佳姿势控制练习的评估是有用的。
