| 总结: | ObjectiveTo observe the effects of neuromuscular exercise (NEMEX) training combined with semiconductor laser therapy on patients with knee osteoarthritis (KOA).MethodsA total of 60 patients with knee osteoarthritis who were treated in the Rehabilitation Medicine Department of the First Affiliated Hospital of Bengbu Medical University from August 2023 to March 2024 were selected and randomly divided into control group and observation group using a random number table method, with 30 cases in each group. The control group received conventional rehabilitation treatments, including joint mobilization and medium-frequency electrical stimulation, along with semiconductor laser therapy at a wavelength of 808 nm and an irradiation power of 400-800 mW, continuous irradiation, 20 minutes per session, once daily, five times weekly for a total of four weeks. The observation group received NEMEX training in addition, including 10 minutes of warm-up exercise; 40 minutes of NEMEX training (stability, posture orientation, lower limb muscle strength training, and functional exercises); and a 10-minute cool-down exercise (involving gait adjustment and stretching), once daily, five times weekly for four weeks. Before and after treatment, Visual Analog Scale (VAS) was used to assess the degree of pain; Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Lysholm Knee Score were used to assess knee joint function; Berg Balance Scale (BBS) was used to assess balance function; the surface electromyography system was used to record the root mean square (RMS) of surface electromyography (sEMG) signals of the quadriceps and hamstring muscles during the squatting and standing of the affected knee joint, and the co-contraction rate (CR) was calculated; the adverse events during the treatment process of the two groups were compared.Results(1) VAS, WOMAC, Lysholm, and BBS scores: compared with those before treatment, VAS and WOMAC scores in both groups after treatment decreased significantly (<italic>P</italic><0.05), while Lysholm and BBS scores increased significantly, and the differences were statistically significant (<italic>P</italic><0.05). Compared with the control group,VAS and WOMAC scores in the observation group after treatment decreased significantly (<italic>P</italic><0.05), while Lysholm and BBS scores were significantly higher, and the differences were statistically significant (<italic>P</italic><0.05). (2) CR: compared with that before treatment, CR in the observation group after treatment decreased statistically, and the difference was statistically significant (<italic>P</italic><0.05), while there was no statistically significant difference in CR in the control group after treatment (<italic>P</italic>>0.05). Compared with the control group,CR in the observation group after treatment was lower, and the differences was statistically significant (<italic>P</italic><0.05). (3) Safety: no adverse events were observed in either group during treatment, and patients exhibited good compliance, indicating a high level of safety.ConclusionNEMEX training combined with semiconductor laser therapy can effectively improve pain, knee joint function, balance function, and muscle coordination and control around the knee joint of patients with KOA, which is worthy of clinical application.
