干预措施:

Interventions:

组别:

常规康复组

样本量:

15

Group:

control

Sample size:

干预措施:

康复训练方法:首先准备两根磅数分别为10磅、20磅的弹力带,患者在第一周进行康复训练时,选择10磅的弹力带进行康复训练,在第三周开始时统一换成20磅的弹力带,在弹力带抗阻的条件下进行以下四个训练动作:仰卧位直腿抬高训练、坐位伸膝抗阻训练、大腿后群肌抗阻训练、坐位屈膝抗阻训练,每个动作每次维持10秒,每次动作间隔5秒,组间间隔10秒,10次/组,3组/天。

干预措施代码:

Intervention:

The rehabilitation training method: This involved the use of two elastic bands, weighing 10 pounds and 20 pounds, respectively. Patients used the 10-pound elastic band for their rehabilitation exercises in the first week. However, they transitioned to using the 20-pound elastic band at the beginning of the third week. As part of their rehabilitation training, the patients performed four specific exercises under resistance by the elastic bands. These exercises included supine straight leg raises, sitting knee extension resistance exercises, resistance training for muscles in the posterior thigh group, and sitting knee flexion resistance training. Each exercise lasted 10 seconds, except for knee extension resistance exercises which lasted 5 seconds. Each exercise was repeated 10 times per group, and each patient was required to complete three groups of each exercise daily.

Intervention code:

组别:

BRFT组

样本量:

45

Group:

BRFT group

Sample size:

干预措施:

1、BRFT组的基础治疗与康复训练方法同对照组。 2、在患者大腿近端安放充气式止血带并缓慢充气,用超声探测足背动脉搏动,记录足背动脉搏动消失时的止血带压力即为足背动脉闭塞压(AOP),分别设定该压力的40%、60%、80%为BFRT时止血带的压力。 3、根据患者的AOP值和分组,将止血带固定于患者患侧大腿根部并施加相应的压力后,再对患膝进行与对照组相同的康复训练,直到训练结束再去除加压带。 4、BFRT的治疗频率:每周进行5次,持续治疗治疗4周。

干预措施代码:

Intervention:

1.The BRFT group received the same basic treatment and rehabilitation training as the control group. 2.Briefly, an inflatable tourniquet was placed on the upper thigh and gradually inflated. Ultrasound was used to confirm the presence of the dorsalis pedis artery pulse, and the pressure at which the pulse ceased was recorded as the dorsalis pedis AOP. The relative tourniquet pressures for BFRT were then set at 40%, 60%, and 80% of the AOP . 3.The tourniquet was placed at the base of the thigh on the patient's side and appropriate pressure was applied based on the AOP value and patient grouping.The afflicted knee received the same rehabilitation training as the control group, and the pressure band was removed end of the training. 4.The recommended treatment frequency for the BFR training cohort is five sessions per week, for four weeks.

随机方法(请说明由何人用什么方法产生随机序列):

具体使用1个不透明的纸箱子,纸箱子里放60张纸条,纸条上注明普通肌力训练组、40%血流限制组、60%血流限制组、80%血流限制组,各15张。研究小组的一名独立成员要求受试者不看纸箱子,伸手到纸箱子随机拿出一张纸条,根据纸条上的标注进行分组。研究小组的一名独立成员和所有结果的主要评估者对这些组进行编码,数据分析不考虑组的分配。

Randomization Procedure (please state who generates the random number sequence and by what method):

Specifically, an opaque paper box was used, and 60 pieces of paper were placed in the paper box, with 15 pieces in each group, including ordinary muscle strength training group, 40% blood flow restriction group, 60% blood flow restriction group and 80% blood flow restriction group. An independent member of the research team asked the subjects not to look at the paper box, but to reach into the paper box and randomly take out a piece of paper, and group them according to the labels on the paper box. An independent member of the research team and the main evaluator of all the results coded these groups, and the data analysis did not consider the allocation of groups.
