Summary
This study measured tibial acceleration using a triaxial accelerometer, revealing high impact forces during walking (up to 3.7 g) and running (up to 10.6 g) in the tibia.
Area of Science:
- Biomechanics
- Human Locomotion
- Orthopedics
Background:
- Understanding lower limb shock absorption is crucial for injury prevention.
- Tibial acceleration provides insights into impact forces during activities like walking and running.
Purpose of the Study:
- To quantify tibial acceleration during walking and running.
- To assess the impact of footwear on tibial acceleration.
- To highlight the necessity of measuring all three acceleration components.
Main Methods:
- A triaxial accelerometer was attached to a Steinmann pin inserted into the tibia of a single subject.
- Measurements were taken during walking and running to record tibial acceleration patterns.
Main Results:
- Tibial acceleration showed minimal variation between steps.
- Resultant tibial acceleration ranged from 2.7 to 3.7 g during walking.
- Maximal tibial accelerations reached 10.6 g during running.
Conclusions:
- Locomotor activities generate significant tibial accelerations.
- Measuring all three components (antero-posterior, medio-lateral, and vertical) is essential for accurate shock quantification.
- These findings have implications for footwear design and injury prevention strategies.
