Summary
Saudi Arabian men show significant differences in hip, knee, and ankle range of motion compared to Scandinavians. Daily life activities may explain these variations in joint flexibility.
Area of Science:
- Orthopedics
- Biomechanics
- Anthropology
Background:
- Range of motion (ROM) in lower extremities is crucial for daily activities.
- Limited comparative data exists on joint ROM between different cultural groups.
Purpose of the Study:
- To measure and compare the range of motion of hip, knee, and ankle joints in Saudi Arabian men.
- To investigate potential cultural influences on joint flexibility.
Main Methods:
- Fifty healthy Saudi Arabian men (30-40 years old) were randomly selected.
- Standardized measurements of hip, knee, and ankle joint range of motion were performed.
- Results were compared to a similar Scandinavian study.
Main Results:
- Significant differences were observed in hip external rotation, knee flexion, and ankle dorsiflexion.
- Saudi Arabian men exhibited distinct joint mobility patterns compared to the Scandinavian cohort.
Conclusions:
- Cultural factors and daily life activities likely contribute to observed differences in lower extremity joint range of motion.
- Further research is warranted to explore the impact of lifestyle on biomechanics across diverse populations.
