| Objective: To investigate the correlation between proprioception and postural control in patients with anterior cruciate ligament (ACL) reconstruction. Methods: Thirty-two patients with ACL reconstruction were included in experimental group, and 10 healthy subjects served as control group. Joint position sense test in isokinetic testing and training system was used to evaluate the proprioception of the knee. Single-leg stance dynamic balance assessment in balance test instrument was used to evaluate the postural control ability. Overall stability index, anterior-posterior stability index and medial-lateral stability index were used as postural stability indices. Results: The overall stability index, anterior-posterior stability index, medial-lateral stability index and joint position sense at 15°, 45°, 75° of the injured and healthy knees in the experimental group were significantly higher than those in the control group (all P<0.05). The overall stability index, anterior-posterior stability index, medial-lateral stability index and joint position sense at 15°, 45°, 75°of the injured knees in the experimental group were significantly higher than those in the healthy side (all P<0.05). There was a positive correlation between joint position sense at 15°, 45° and overall stability index, anterior-posterior stability index, medial-lateral stability index (all P<0.05). There was a positive correlation between the joint position sense at 75° and the overall stability index (P<0.01). Conclusion: The proprioception and postural control ability of injured side and healthy side decreased in patients with ACL reconstruction. There was a positive correlation between proprioception and postural control ability. It is suggested to strengthen the training of proprioception and posture control in both nonoperated and operated knees. |
