| In long-term high-load,high-intensity training and competition,the knee joint plays a buffer and connects the entire force transmission in jumping,twisting and rapid cutting,and when the knee joint suffers from sports injuries,there will be pain,swelling,fever,weakness and decreased joint function.The knee joint is one of the main joints of stress in humans,and its structural complexity makes it difficult to accurately locate and diagnose pain when it occurs.Anterior knee pain(AKP)is a common symptom in athletes’ knee joint sports injuries,accounting for more than 60%,the reason may be that the medial and medial quadriceps muscle strength is not balanced,the drag patellar activity trajectory is not normal,resulting in pain around the patella,and athletes in intense training and major competitions,more susceptible to knee pain,therefore,the diagnosis and treatment of knee pain should be strengthened to ensure the physical and mental health of athletes.If treatment measures are not taken in time or recovery is not carried out quickly,the muscle strength of athletes will be greatly reduced,which will affect the progress of training and competition.However,although the current treatment methods can achieve the purpose of treating athletes’ knee pain,conventional treatment is more extensive,the targeting of the quadriceps muscle is poor,and there is no active contraction training of muscles during the treatment process,so that the treatment efficiency is not high,the treatment time is long,the continuous effect after treatment is limited and there is no complete combination of active and passive,and the muscle strength of athletes cannot maintain the original training intensity.Clinically,in order to improve the efficiency of treatment,comprehensive treatment has been carried out by combined means.Myofascial Trigger Points(MTr Ps)treatment has been commonly used to treat complex tendon,joint,and bone diseases,in which acupuncture technology can effectively release the muscular layer in the quadriceps muscle,and combined with resistance training to achieve a combination of active and passive therapeutic effects,so that athletes can maintain muscle strength during treatment to adapt to the needs of training and competition.Objective: To investigate the efficacy of acupuncture myofascial trigger points combined with quadriceps resistance training for anterior knee pain and to assess the effects on pain,function,quadriceps strength,and temperature in the knee region and quadriceps region.Methods: The 58 athletes recruited with AKP were randomly divided into three groups: experimental group(n=20),control group 1(n=19),and control group 2(n=19).The test group was treated with acupuncture myofascial trigger points combined with quadriceps resistance training;Control group 1 was treated with conventional physical factor therapy combined with resistance training;Control group 2 was treated with conventional physical factor therapy three times a week to observe its efficacy.Prior to treatment,we conducted a comprehensive assessment of the patient’s visual analogue assessment(VAS),knee function scale(Lysholm),quadriceps muscle strength,knee region temperature difference and quadriceps region temperature difference for a total of 6 weeks to ensure the patient’s healing effect.Results:1)In the VAS score index,the three groups showed a significant difference(P<0.05)compared with the baseline at week 6,while the experimental group also showed a significant difference(P<0.05)at week 3,and the control group 1 also showed a significant difference(P<0.05)at week 6 and week 3.In addition,the comparison between the three groups also showed that the VAS score of the experimental group at week 3 was significantly smaller than that of control group 1 and control group 2,with an extremely significant difference(P<0.01),and a significant difference between the experimental group and control group 1 compared with control group 2 at week 6(P<0.05).2)Lysholm score index,intra-group comparison: the three groups of subjects had significant differences(P<0.05)compared with the baseline period at week 3 and 6,and the three groups of subjects had significant differences(P<0.05)compared with week 3at week 6;comparison between the three groups: At week 3,the Lysholm score of the experimental group was greater than that of control group 1 and control group 2,and there was a significant difference between the three groups(P<0.05).3)In the muscle strength test,intra-group comparison: the patients in the experimental group and the control group 1 had significant differences(P<0.05)compared with the baseline muscle strength test indicators at the 3rd week and the 6th week,and the experimental group and the control group 1 had significant differences(P<0.05)compared with the 3rd week at week 6;the comparison between the three groups: the muscle strength test indicators of the experimental group and the control group 1 compared with the control group 2 at week 6 had a significant difference(P<0.05).4)In the index of temperature difference in the knee region,the three groups showed a significant difference(P<0.05)compared with the baseline at week 6,and the experimental group and the control group 1 also showed a significant difference at the3 rd week,and these differences were confirmed between the 6th and 3rd weeks.In addition,at week 3,there were significant differences in the temperature difference between the knee region in the experimental group than in control group 1 and control group 2,and these differences were confirmed at week 3.At week 6,the difference in knee temperature between the experimental group and the control group 1 was significant,and the difference in the control group 2 was more prominent,and its statistical significance was also significant(P<0.05).5)In the temperature difference index of quadriceps thermography,Intra-group comparison: the regional temperature difference between the experimental group and the control group 1 at week 3 and week 6 was significantly lower than their baseline level(P ≤ 0.05),and the regional temperature difference between the experimental group and the control group 1 at week 6 compared with the third week(P<0.05);the regional temperature difference between the experimental group at the third week of intervention was significantly lower than that of the control group 1 and control group2(P≤0.05),and the regional temperature difference between the experimental group and the control group 1 at the sixth week of intervention was significantly lower than that of the control group 2(P≤0.05).Conclusion:1)Acupuncture MTr Ps combined with quadriceps resistance training is a safe and effective combination treatment,which can relieve the pain symptoms of athletes with knee pain in a shorter time,and can effectively improve the function of knee joints in athletes with knee pain.2)Acupuncture MTr Ps combined with quadriceps resistance training can effectively maintain or even improve the quadriceps extensor muscle strength of athletes with knee pain.3)Acupuncture MTr Ps combined with quadriceps resistance training on the reduction of regional temperature difference in knee joints and quadriceps muscles of athletes with anterior knee pain,and obvious effect on local blood circulation,and more significant short-term effect. |
