Objective: The purpose of this study was to investigate the relationship between internal tendon exertion and external total grip strength through the cadaver hands experiment.
Background: Many previous studies have been conducted to accurately measure the strength of the internal muscles of the human body, but there have been many difficulties in research, including the supply and demand of cadaver hands and the establishment of systems for data collection.
Method: The donated four fresh cadaver hands were used, and the Cadaver Finger Force Measurement (CFM) system was developed to control the strength of the hand muscles. Grip span (4 levels: 45, 50, 55, 60mm), total tendon force (3 levels: 70, 105, 140N), and tendon force ratio (1:1, 1:1.5, 1:2, 1:3) were selected as independent variables, and total grip strength and internal tendon force/external force ratio (I/E ratio) were selected as dependent variables.
Results: Grip span 55 and 60mm had a total grip strength of 28.8N and 27.5N, respectively, showing a relatively larger (approximately 15%) than 24.7N and 24.3N of 45mm and 50mm, respectively. The total grip strength for tendon forces showed the lowest total grip strength (19.0N) at 70N and the largest total grip strength (33.7N) when increased to 140N tendon force. The I/E ratio according to grip span was low in 55mm and 60mm grip span, and the ratio was relatively high in 45mm and 50mm grip span. The I/E ratio based on total tendon was the lowest (3.9) at tendon force of 70N and the highest at tendon force of 4.5 at 140N.
Conclusion: It was confirmed that the external force of the hand grows together as the internal force (tendon exertion) increases, and that the rate of increase also depends on the magnitude of the external force.
Application: The findings of this study provide useful insights and information for understanding the relationship between the external force of the hand and the force of the internal muscles that exert various grip or force.
