Effect of Mouth Opening Training Stick Combined with Oral Massage on Mouth Opening Difficulty in Head and Neck Cancer Patients after Treatment

引用

Journal of Biosciences and Medicines 2024年第6期12卷 43-51页

作者： jinhua liu Qiong Wen Department of Oncology Jingzhou First Peoples Hospital Jingzhou China

Objective: To study the application effect of mouth-opening training sticks combined with oral massage on patients with mouth-opening difficulty after treatment for head and neck cancer. Methods: Using convenient sampling, 60 patients with mouth-opening difficulty after treatment for head and neck cancer admitted to the Oncology Department from February 2022 to October 2023 were selected for a 2-week exercise and nursing program. The patients were divided into a control group (February 1, 2022 to November 30, 2022) and an observation group (December 1, 2022 to October 31, 2023), with 30 patients in each group. The control group underwent routine mouth-opening functional exercises combined with cork for oral support training, while the observation group underwent routine mouth-opening functional exercises combined with oral massage and mouth-opening training sticks for oral support training. The mouth-opening degree, mouth-opening difficulty level, comfort level, compliance, and quality of life were observed in both groups. Results: Before the intervention, there were no statistically significant differences in mouth-opening degree and mouth-opening difficulty level between the two groups (P > 0.05). After the intervention, the mouth-opening degree, mouth-opening difficulty level, oral comfort level, compliance, and QLICP-HN scores in the observation group were all better than those in the control group, with statistically significant differences (P < 0.05). Conclusion: The combination of mouth-opening training sticks and oral massage with mouth-opening functional exercises can effectively improve the degree of mouth-opening difficulty, enhance oral comfort, increase compliance with mouth-opening exercises, and improve quality of life.

语言是科技和文化的主要载体,许多谬误都源于语言使用的逻辑误解,只有通过语言使用的逻辑分析才能得到澄清和消除。从术语的基本要求出发,针对“规划”及其相关用语在现实使用中的歧义和模糊问题,引入语言形态分析等语言学的基础知识,结合相关文献档案和工程实践,横向辨析其基本词义,纵向梳理其历史使用逻辑,逐一考辨、驳斥、澄清“规划”相关用语和语句的阅读理解方式,力求更清晰地认识、理解“规划”及其相关概念的源流。“规划”一词是不同语种、异质规划技术体系及对立的意识形态等条件相互作用的结果。在中国式现代化中塑造“中国规划”,应对规划体系保持历史耐心,使规划学科更准确地“说中国话”。

资本的本性是最大限度追求剩余价值,其本质规定性内含文明化趋势及历史限度。作为资本主义社会的运行逻辑和主导原则,资本逻辑不仅从时空维度全面布展了现代社会与现代文明,还因资本本性和内在矛盾的发展潜藏着自我瓦解和现代文明重建的必然趋势。立足现实个人的生存生产生活,追求人的解放和自由全面发展旨趣,马克思资本逻辑批判不仅是对资本主义文明的批判,更是在消解资本逻辑的过程中探寻人类文明新形态的积极尝试。从时间和空间双重向度透视资本主义文明,有助于阐明马克思资本逻辑批判语境中的文明意蕴及其当代价值。
