| Outline of Final Research Achievements |
The purpose of this study was to evaluate the hardness distribution of body surfaces, which are assessed by the acupuncturist during diagnosis and treatment in the clinic. Using several devices and spring strengths, we measured the hardness of six different gel sheets of acupuncture practice pads, as well as the hardness distribution of the induration-embedded and breast cancer palpation models. We determined that the most suitable combination for a multipoint hardness measurement system was the PEK-1 with a spring strength of 4.90 N in the main axis probe. In biological applications, we confirmed that changes in the hardness distribution and hardness of tendons with a width of about 3 mm can be measured using the forearm when different fingers move. In clinical applications, we observed that the contractile hardness and the hardness difference between contraction and relaxation of diseased muscles were asymmetrical in patients suspected of lateral epicondylitis.
