Abstract

|
|
Background: To investigate and describe the acceleration of the knee during walking in patients with osteoarthritis of knee and healthy adults.
Methods: 22 patients with osteoarthritis of knee and 22 heathy adults participated in this study. The accelerometer fixed at left fibular head was used to record anterior-posterior, medio-lateral and superior-inferior accelerations of the knee during walking.
Results There was significant increase in lateral and anterior 1st peak of acceleration at loading response in the patients with osteoarthrits of knee compared to healthy adults (P＜0.01). There was significant decrease in cadence in the patients with osteoarthritis of knee compared to heathy adults (P＜0.01), but there was no significant correlation between cadence and 1st peak of acceleration at loading response. There was correlated with anterior and lateral acceleration in all subjects (P＜0.01). Also there was relationship between anterior-posterior, medio-lateral and superior-inferior acceleration
in all subjects (P＜0.01).
Conclusion: The accelerometer can be an easy and useful way to evaluate patients with osteoarthritis of knee.
