Abstract
[Purpose] The purpose of this study was to verify the validity of soleus muscle strength measurements made by hand-held dynamometer (HHD). [Subject] The maximum torque value and the maximum muscle strength of 28 limbs of 14 healthy adults were measured. [Methods] The isometric soleus muscle strength was measured by 5 methods: by HHD using manipulative resistance, and a fixed belt; standard, Biodex measurement and, Biodex measurement of the target soleus muscle; and MMT. [Results] There was a significant correlation between the HHD method using a fixed belt and the Biodex measurement of the target soleus muscle. [Conclusion] The validity of the HDD method using a fixed belt was confirmed.
