Abstract：Objective To explore the effects of quadriceps relaxation training combined with Zhoulin spectrum therapeutic apparatus on knee joint pain and functions as well as inflammatory factors in military personnel with post-exercise knee pain.Methods A total of 80 military personnel with knee pain caused by high-intensity training between February 2024 and January 2025 were selected as subjects and randomly divided into a control group(Zhoulin spectrum therapeutic apparatus alone,n=40)and an observation group(quadriceps relaxation training combined with Zhoulin spectrum therapeutic apparatus,n=40).The course lasted 4 weeks,with both groups receiving guided therapy and relaxation training under medical supervision.Clinical efficacy,scores of the Lysholm Knee Scoring Scale(LKSS),scores of the Visual Analog Scale(VAS),and rates of recurrence were compared between the two groups before and after 4 weeks of treatment.Levels of interleukin(IL)-6 and IL-10 were compared at 1 day before treatment,1 day after treatment,and 3 days after treatment.Results The clinical efficacy in the observation group was much better than that of the control group(Z=-1.993,P=0.046).Both groups had their VAS scores reduced and Lysholm knee scores increased after 4 weeks of treatment(t=12.079,9.038,20.574,13.148,all P＜0.001).The recurrence rate in the observation group was lower than that of the control group at 4 weeks post-treatment(x2=6.667,P=0.010).Simple effect analysis by group found that IL-6 levels were higher(P=0.005,＜0.001)while IL-10 levels were lower(P=0.011,＜0.001)in the control group than in the observation group at 1 and 3 days post-intervention.Time-based simple effect analysis showed that IL-6 levels peaked at 1 day post-treatment and declined after 3 days of treatment in both groups(both P＜0.001).IL-10 levels kept increasing in the observation group(all P＜0.05),and were elevated in the control group at 1 and 3 days post-treatment compared with baseline(both P＜0.001).Conclusion Combining quadriceps relaxation training with Zhoulin spectrum therapeutic apparatus can yield better outcomes in military personnel with post-exercise knee pain,improve their clinical symptoms,enhance knee function,mitigate pain intensity,lower recurrence rates,and regulate inflammatory cytokine levels.
