虚拟现实生物反馈训练联合口腔定位疗法对口腔癌术后吞咽障碍的效果OA

Objective To explore the application of virtual reality biofeedback training combined with oral localization therapy in dysphagia after oral cancer surgery. Methods From May,2023 to July,2024,86 patients with dysphagia after oral cancer surgery in Zhejiang Provincial Peo-ple's Hospital were randomly divided into control group(n=43)and experimental group(n=43).The control group received conventional swallowing function training,while the experimental group added virtual reality bio-feedback training combined with oral positioning therapy,for four weeks.The Standardized Swallowing Func-tion Assessment Scale(SSA),Functional Oral Intake Scale(FOIS)and M.D.Anderson Dysphagia Inventory(MDADI)were used for evaluation before intervention,and two weeks,four weeks and eight weeks after inter-vention. Results For scores of SSA,the main effects of group(F=150.190,P<0.001,η2p=0.641)and time(F=230.870,P<0.001,η2p=0.733),as well as the interaction effect(F=16.910,P<0.001,η2p=0.168)were all significant.For scores of FOIS,the main effects of group(F=59.601,P<0.001,η2p=0.415)and time(F=89.464,P<0.001,η2p=0.516),as well as the interaction effect(F=7.990,P<0.001,η2p=0.087)were all significant.For scores of MDADI,the main effects of group(F=33.133,P<0.001,η2p=0.283)and time(F=49.650,P<0.001,η2p=0.371),as well as the interaction effect(F=3.224,P=0.023,η2p=0.037)were all significant. Conclusion Virtual reality biofeedback training combined with oral localization therapy could improve the swallowing function,oral feeding ability and overall quality of life of patients with dysphagia after oral cancer surgery.
