目的：本研究的目的是探讨使用手持式组织硬度计来评估骨骼肌的机械性能的可行性。方法：本观察性研究包括33名健康男性（年龄，22.4 +/- 4.4岁）和33名健康女性（年龄，23.7 +/- 4.2岁）。参与者被置于仰卧位，并在身体右侧50%大腿长度处测量股直肌上的组织硬度和肌肉的剪切模量。在同一位置，使用B型超声检查测量皮下脂肪组织厚度和肌肉厚度。为了检查皮下脂肪组织厚度、肌肉厚度和肌肉剪切模量与组织硬度的关联，使用逐步双向消除方法进行线性回归。逐步线性回归显示皮下脂肪组织厚度（r =-0.38，P = .002）和肌肉剪切模量（r = 0.27，P = 0.03）与组织硬度显著相关。脂肪组织厚度，肌肉剪切模量，和组织硬度显示了手持式组织硬度计用于评估骨骼肌的机械性能的局限性和可行性。
Objectives: The purpose of this study was to examine the feasibility of using handheld tissue hardness meters to assess the mechanical properties of skeletal muscle.Methods: This observational study included 33 healthy men (age, 22.4 +/- 4.4 years) and 33 healthy women (age, 23.7 +/- 4.2 years). Participants were placed in a supine position, and tissue hardness overlying the rectus femoris and the shear modulus of the muscle were measured on the right side of the body at 50% thigh length. In the same position, subcutaneous adipose tissue thickness and muscle thickness were measured using B-mode ultrasonography. To examine the associations of subcutaneous adipose tissue thickness, muscle thickness, and muscle shear modulus with tissue hardness, linear regression using a stepwise bidirectional elimination approach was performed.Results: Stepwise linear regression revealed that subcutaneous adipose tissue thickness (r = -0.38, P = .002) and muscle shear modulus (r = 0.27, P = .03) were significantly associated with tissue hardness.Conclusions: Significant associations among adipose tissue thickness, muscle shear modulus, and tissue hardness show the limitations and feasibility of handheld tissue hardness meters for assessing the mechanical properties of skeletal muscles.
