  Title Handheld tissue hardness meters for assessing the mechanical properties of skeletal muscle: A feasibility study
Journal J Manipulative Physiol Ther. 2016 Sep;39(7):518-522
Peer Review Yes
Publication Type Article

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.
