Summary: | [Purpose] The purpose of this study was to examine the co-contraction of the knee during one foot standing in total knee arthroplasty (TKA) patients and to investigate the relation between the co-contraction and balance function. [Participants and Methods] Nine subjects (TKA group) at four weeks after TKA and 10 healthy, age-matched controls (healthy group) participated in this study. The subjects performed a one foot standing task, and the co-contraction index (CI) of the knee was measured. [Results] There was a significant difference between the two groups in CI. In the TKA group, there was a significantly negative correlation between the CI during the transition phase of the task and FRT. [Conclusion] The results suggest that the center of gravity movement with change in posture is affected by the co-contraction of the knee in TKA patients. |
