摘要
目的利用下肢补偿助力离心力量训练干预髌股疼痛综合征(Patello-femoral pain syndrome,PFPS)患者,评估力量训练的康复效果。方法选取北京体育大学符合准入标准PFPS的运动员患者20人并随机等分为实验组和对照组,对实验组进行为期6周的下肢离心力量训练,每周2次。实验组成员采用补偿助力离心综合训练系统(CC03)做负重深蹲动作,负荷强度以正确动作能够完成最多重复次数的最大重量(repetition maximum,RM)为单位,具体负荷为12RM向心力的120%,即是连续12次的最大向心力量负荷的120%,15个/组,每次2组。训练前后均使用BTE Primus(RS)系统测试受试者的最大平均向心峰值力矩和最大平均离心峰值力矩,使用SPECTRON IR医用红外线热成像诊断系统测试患处膝关节与周围正常皮肤温度差,并使用膝关节损伤和骨关节炎评分(knee injury and osteoarthritis outcome score,KOOS),视觉模拟评分(visual analogue scale,VAS)对PFPS受试者进行评价。结果训练后实验组受试者的双侧下肢平均离心力量和KOOS评分与训练前相比明显提高(P<0.05),VAS评分和患处膝关节与周围正常皮肤温度差有明显降低(P<0.05)。同时对照组受试者的各项数据并无明显的变化(P>0.05)。实验后实验组与对照组相比,实验组受试者训练后的VAS评分和患处膝关节与周围正常皮肤温度差与对照组相比明显下降,双侧下肢平均离心力量和KOOS评分明显的升高(P<0.05)。结论下肢补偿助力离心力量训练对髌股疼痛综合征的改善具有显著效果。
Objective To use the Compensation Eccentric Strength Training System on patients with Patello-femoral pain syndrome,and assess the influence of rehabilitation on strength training.Methods 20 athletes who met the entry criteria PFPS from Beijing sport university were randomly divided into experimental and control groups.The experimental group underwent six weeks of lower limb centrifugal strength training,twice a week,using compensation eccentric strength training system（CC03）.Load intensity of the subject were 120% 12 RM maximum amount of centripetal force,15/group with 2for each group.Use the BTE Primus（RS）maximum radial centrifugal peak torque and peak torque maximum system test subjects before and after training.Using the SPECTRON IR infrared thermal imaging for medical diagnostic test systems,affected part of the knee and surrounding normal skin temperature difference.PFPS subjects were evaluated using KOOS,VAS ratings.Results The average centrifugal force and KOOS score after training from subjects in the experimental group were significantly improved compared with before training（P〈0.05）.VAS score and suffering knees and surrounding normal skin temperature difference were significantly lower（P〈0.05）.At the same time there was no clear data of the change in the control group subjects（P〈0.05）.Comparing the experimental group and the control group after the experiment,we found VAS score and knee lesion compared with the surrounding normal skin temperature of the subjects in the experimental group difference with the control group decreased significantly,bilateral lower extremity average centrifugal force and KOOS score was significantly increased（P〈0.05）.Conclusion The improvement of the centrifugal force of the lower limbs has a therapeutic effect on PFPS.
