Application of Microwave Therapy Combined with Continuous Eccentric Exercise with Incremental Load in Chronic Musculoskeletal Pain and Its Effect on Muscle Fitness and Pain Mediators
Objective To investigate the application of microwave therapy combined with continuous eccentric exer-cise with incremental load in chronic musculoskeletal pain and its effect on muscle fitness and pain mediators.Methods A total of 189 patients with chronic musculoskeletal pain treated from September 2021 to September 2022 were selected and di-vided into groups A,B and C with 63 cases in each group according to different intervention plans.Group A was given micro-wave therapy combined with continuous eccentric exercise with incremental load,group B was given continuous eccentric exer-cise with incremental load,and group C was given microwave therapy.The pain degree[visual analogue scale(VAS)]and pain nature(ID pain scores),muscle fitness(peak moment,moment acceleration energy,average power),pain mediators[prostaglandin E2(PGE2),Substance P,β-endorphin(β-EP)]and Pittsburgh Sleep Quality Index(PSQI)score before treatment and after 1 or 2 courses of treatment,as well as the Short Form of Healthy Living Conditions Survey(SF-36)and the International Osteoarthritis Scale(Lequesne)score before treatment and during 2 courses of treatment were compared among the three groups.Results After 1 and 2 courses of treatment,VAS and ID pain scores in group A were lower than those in group B and group C.After 2 courses of treatment,the peak moment,torque accelerating energy and average power flexor and extensor muscles of group A were higher than those of groups B and C,and higher in group C than in group B(P<0.05).After 1 and 2 courses of treatment,serum PGE2 and SP in group A were lower than those in groups B and C,while serum β-EPwas higher than that in groups B and C;serum PGE2 and SP in group B were lower than those in group C,while serum β-EP was higher than that in group C(P<0.05).Before treatment and after 1 or 2 courses of treatment,PSQI scores in the three groups showed a decreasing trend(P<0.05).After 1 and 2 courses of treatment,PSQI scores in group A were lower than those in groups B and C(P<0.05).After 2 courses of treatment,the SF-36 score in the three groups was higher than that before treatment,while the Lequesne score was lower than that before treatment(P<0.01).The SF-36 score of group A was higher than that of group B and C,while the Lequesne score was lower than that of group B and C(P<0.05).Conclu-sion Microwave therapy combined with continuous eccentric exercise with incremental load can be used in the treatment of chronic musculoskeletal pain,which can improve the muscle fitness indicators and pain mediators of patients,so as to restore sleep quality,quality of daily life and bone and joint function of patients.
