RESUMEN
Objective:To explore the effect of blood flow restriction training on the quadriceps femoris and on knee stability after anterior cruciate ligament reconstruction.Methods:Forty patients recovering from anterior cruciate ligament reconstruction were randomly divided into an experimental group and a control group, each of 20. In addition to routine rehabilitation training, the control group was given routine knee flexion and extension strength training, while the experimental group trained for an additional 20 minutes doing knee flexion and extension resistance training with the blood pressure in their groins at 70% of their individual arterial occlusive pressure. (The mean pressure was (123±11.23)mmHg). The training lasted 8 weeks, three times a week. Knee function and hamstring and quadriceps peak torque were assessed before and after the intervention using a Lysholm scale and Humac Norm isokinetic muscle strength tests.Results:There were no significant differences between the two groups in any of the measurements before the training. After the intervention, all of the measurements had improved significantly in both groups, with the average Lysholm score, H/Q% and peak torque of the experimental group significantly better than the control group′s averages.Conclusions:Blood flow restriction training can improve the effectiveness of quadriceps femoris strength, knee stability and knee function training after anterior cruciate ligament reconstruction.
RESUMEN
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.
RESUMEN
Objective:To explore any effect of training assisted by a pelvic rehabilitation robot on trunk control and walking after cerebral infarction.Methods:Forty cerebral infarction survivors with hemiplegia were randomly divided into an experimental group and a control group, each of 20. Both groups were given routine neurological medication and rehabilitation training, while the experimental group was additionally provided with 20 minutes of robot-assisted gait training daily, five times a week, for 4 weeks. Before and after the intervention, the motor function, walking function, trunk control and pelvic movement were assessed using a simplified version of the Fugl-Meyer assessment (FMA-LL), functional ambulation categories (FAC) and the trunk control test (TCT).Results:After the treatment, significant improvement was observed in all of the above measurements in both groups. The average FMA-LL, FAC and TCT results of the experimental group as well as their average pelvic lateral displacement, height displacement, rotation angle and roll angle were all significantly superior to the control group′s averages.Conclusions:Robot-assisted training can effectively improve lower limb motor functioning, trunk control, walking and pelvic motion after cerebral infarction, with better curative effect than routine rehabilitation training alone.

Objective:To explore the effect of a pelvis-assisting rehabilitation robot on lower limb function and knee proprioception after cerebral infarction.Methods:Forty hemiplegic cerebral infarction survivors were randomly divided into an experimental group and a control group, each of 20. Both groups were given routine neurological medication and rehabilitation training, while the experimental group was additionally provided with 20 minutes of robot-assisted gait training daily, five times a week for four weeks. Before and after the intervention, motor function, balance, walking function and knee joint proprioception were assessed using the simplified Fugl-Meyer lower limb assessment, the Berg balance scale, functional ambulation categorization and the Humac Norm isokinetic tester.Results:After the treatment, significant improvement was observed in all of the above measurements in both groups, but the improvements were significantly greater in the experimental group.Conclusions:Robotic pelvic assistance can effectively improve lower limb motor function, balance, knee proprioception and walking after cerebral infarction.
RESUMEN
Objective:To explore the effect of robot-assisted training and repetitive transcranial magnetic stimulation (rTMS) on the lower limb function of hemiplegic stroke survivors.Methods:Forty hemiplegic stroke patients were randomly divided into a treatment group ( n=20) and a control group ( n=20). Both groups were given routine rehabilitation training and robot-assisted walking training, but the treatment group was additionally treated with rTMS at 1Hz applied to the primary motor cortex M1 area at an intensity of 80% of the resting motor threshold. The stimulation time was 5 seconds at 5-second intervals, 600 pulses each time, five times a week for 8 weeks. Lower limb motor function, balance and walking function were assessed before and after the intervention using the Fugl-Meyer assessment for the lower extremities, the Berg balance scale and the Holden walking function scale. Results:There was no significant difference between the two groups in any measurement before the training, but after the intervention all of the measurements had improved significantly in both groups, with the average Fugl-Meyer score, Berg score and Holden grading significantly better in the treatment group.Conclusion:Repetitive transcranial magnetic stimulation can improve the effectiveness of robot-assisted walking training in improving lower limb motor function, balance and walking after a stroke.
