ABSTRACT
Objective:To investigate the clinical effect of proprioceptive trainning on patients after anterior cruciate ligament reconstruction. Methods:From March, 2017 to September, 2018, 30 patients after anterior cruciate ligament reconstruction were randomly divided into control group (n = 15) and experimental group (n = 15). All the patients received routine rehabilitation for eight weeks after operation. Then, the control group received routine rehabilitation, while the experimental group received proprioceptive trainning in addition, for eight weeks. They were assessed with Lysholm score, Isokinetic Testing and Training System, and Dynamic Balance Tester eight and 16 weeks of training. Results:Lysholm score increased in both groups after treatment (t > 16.687, P < 0.001), with decrease of error of knee flexion in 15°, 45° and 75° (t > 2.433, P < 0.05), and speed of centre of gravity moving with eyes closed on stable and unstable floors (t > 2.444, P < 0.05). Compared with the control group, Lysholm score was more (t = 4.150, P < 0.05), errors of knee flexion in 15° and 45° were less (t > 2.710, P < 0.05), and speed of centre of gravity moving with eyes closed on unstable floors was less (P<0.05) in the experimental group. Conclusion:Proprioceptive trainning is effective on proprioception and function of knee after anterior cruciate ligament reconstruction, to improve postural control.
