Hypothesis
A higher level of knee pain is associated with higher lateral trunk motion in patients with knee OA.
Conclusion
Pain is associated with lateral trunk motion, but this association is weak and influenced by age, gender, self-reported stiffness, and maximum walking speed.
Supporting Evidence
- In regression analyses, pain was associated with more lateral trunk motion.
- More lateral trunk motion was associated with younger age, being female, higher self-reported knee stiffness, and higher maximum walking speed.
- The weak relationship between lateral trunk motion and knee pain was consistent with previous studies.
Takeaway
When people with knee pain walk, they might move their upper body side to side more, but this isn't a strong connection and depends on other factors like age and how fast they can walk.
Methodology
Patients with knee OA were tested for lateral trunk motion during walking, and knee pain was measured using VAS and WOMAC questionnaires.
Potential Biases
Potential biases may arise from self-reported measures and the exclusion of certain patients based on specific criteria.
Limitations
The association between lateral trunk motion and knee pain was found to be weak and influenced by several confounding factors.
