Abstract:
Objective:To explore any effect of blood flow restriction during exercise on knee proprioception and motor coordination after anterior cruciate ligament (ACL) reconstruction.Methods:Thirty patients recovering from ACL reconstruction were randomly divided into an experimental group and a control group, each of 15. Both groups were given routine rehabilitation training, while the experimental group was additionally provided with 45 minutes of training with blood flow restriction, 3 times a week for 8 weeks. The blood flow restriction training involved constant pressure in the groin while the patient performed knee flexion and extension resistance training, squats, alternate knee flexion and extension and ergometer cycling. Before and after the intervention, both groups′ knee function, proprioception and lower limb motor coordination were evaluated using the Lysholm knee scale, the Humac isokinetic measurement system and surface electromyography.Results:Before the experiment there were no significant differences between the two groups in any of the measurements. After the intervention, both groups′ average Lysholm score had improved significantly, and errors in reproducing a knee angle had decreased significantly. Significantly better improvement was observed in the observation group than in the control group. That group′s average coordinated contraction rate on the affected side in extension and flexion was also significantly better than the control group′s ave-rage. Indeed, there were no significant differences in the contraction rates between the healthy and affected sides.Conclusions:Training with restricted blood flow can significantly improve knee function, proprioception and motor coordination after anterior cruciate ligament reconstruction.
