Hypothesis
The study aims to investigate the motion of the index finger joints generated by individual extrinsic muscles.
Conclusion
The study provides new insights into how individual extrinsic muscles contribute to the motion of the index finger joints.
Supporting Evidence
- The FDP muscle generated motion at all finger joints, while the FDS did not affect the DIP joint.
- The EDC and EIP muscles produced similar motion patterns at the MCP and PIP joints.
- The study used a motion capture system to accurately record joint movements.
Takeaway
This study looked at how different muscles move the finger joints. It found that some muscles can move multiple joints at the same time.
Methodology
Ten fresh-frozen cadaveric hands were used to measure the motion generated by individual extrinsic muscles at the finger joints.
Limitations
The study's findings may not fully apply to living subjects due to differences in tissue properties and the limited force applied during testing.
Participant Demographics
6 female and 4 male cadaveric hands, average age 55.2 years.
