Clinical Effect Of Neuromuscular Training Combined With Muscle Strength Training On Patellofemoral Pain Syndrome

Objective: To observe the clinical effects of neuromuscular training combined with muscle strength training and muscle strength training alone on patients with patellofemoral pain syndrome,and to explore whether the combined intervention program is better than the muscle strength training program alone,with a view to patellofemoral pain syndrome the sports training program provides a certain reference.Methods: The 48 male and female subjects who met the experimental requirements were randomly divided into two groups.The subjects were not clear about the grouping situation.The experimental group received neuromuscular training combined with muscle strength training,and the control group received pure muscle strength training.The training intensity,time,and frequency were the same as those of the experimental group.The experimental intervention was 4 weeks,3 times a week,with at least 1 day between two training sessions.The experimental indicators were collected before the intervention and after the last intervention.The visual analog scale(VAS)was used to evaluate the knee joint pain,the anterior knee pain scale(AKPS)was used to evaluate the functional status of the knee joint,and the Y balance test(YBT)was used to evaluate the lower limbs.For dynamic stability,use the BTE Primus RS isokinetic muscle strength assessment training instrument to analyze the relative peak torque and the flexor-extensor torque ratio of the knee joint.Follow up the VAS score and AKPS score at the 4th and 12 th week after the intervention.Results:(1)The VAS pain scores of the two groups of subjects after exercise training and follow-up were significantly lower than before training(P<0.01).Compared with the control group,the pain symptoms of the experimental group were significantly relieved after exercise training(P<0.05),and the VAS score was lower during follow-up,and the difference was statistically significant(P<0.01).In the control group,the pain level at the 12 th week follow-up after the training was significantly higher than that at the end of the training(P<0.01);(2)The functional status of the two groups of subjects after the exercise training and the follow-up was significantly better than before the training(P<0.01).After the exercise training and the 4th week follow-up,there was no significant difference in AKPS scores between the two groups(P>0.05).At the 12 th week follow-up after the intervention,the functional status of the experimental group was better than that of the control group(P<0.05).The AKPS scores of the control group at follow-up were lower than those at the end of exercise training(P<0.05);(3)After exercise training,the YBT test results of the affected side of the two groups of subjects were in three directions(front side,The distance between the posterior medial and posterior lateral)and the difference of the affected side were significantly better than before training(P<0.01);after the exercise training,the distance of the affected side in the three directions and the difference of the affected side of the experimental group were excellent Compared with the control group(P<0.05);the experimental group's healthy side performed better in the posteromedial and posterolateral directions than before training(P<0.01),while the control group's healthy side had no statistically significant difference compared to before intervention(P> 0.05);(4)At three angular velocities of 60°/s,120°/s,and 180°/s,the relative peak torque of the extensors of the two groups of subjects before and after the intervention was significantly increased(P<0.01),and the flexion and extension The muscle torque ratio was significantly lower than before the intervention(P<0.01).At the three angular velocities,the relative peak torque of the flexors and extensors of the experimental group after intervention was better than that of the control group(P<0.05).At 120°/s and 180°/s angular velocities,the ratio of flexor and extensor torque in the experimental group was significantly lower than that in the control group(P<0.05).Conclusion:(1)After 4 weeks of intervention,neuromuscular training combined with muscle strength training and pure muscle strength training can effectively relieve the pain of patients with PFPS,improve function,and enhance lower limb balance and muscle strength than before the intervention;(2)and Compared with pure muscle strength training,neuromuscular training combined with muscle strength training has more advantages in relieving pain,improving function,enhancing lower limb muscle strength and balance;(3)Follow-up revealed that neuromuscular training combined with muscle strength training resulted in lower pain recurrence and better functional improvement compared with muscle strength training alone.
