用途：本研究探讨了两种吞咽动作的生物力学和肌电特性（用力吞咽和门德尔松动作）和1例吞咽-非特异性（呼气肌肉力量训练[埃姆斯特]）吞咽治疗任务为了检查每一种对健康成年人舌骨运动和相关颏下激活的不同影响，方法：25名健康男性和女性成年人（M=25岁）参加了这项前瞻性的实验研究，其中一个参与者组。每个参与者完成了所有的研究任务（包括正常吞咽，门德尔松动作吞咽，努力吞咽，和埃姆斯特任务）在随机顺序同时videoflucoscopy和表面肌电图recording.Results：结果显示舌骨运动的轨迹测量的整体位移和角度的舌骨仰角显着差异。结论：3种实验任务对舌骨运动的影响存在任务特异性和超负荷原则的差异。这些原则对于制定有效的康复计划非常重要。最后对今后的研究方向提出了建议。
Purpose: This study investigated the concurrent biomechanical and electromyographic properties of 2 swallow-specific tasks (effortful swallow and Mendelsohn maneuver) and 1 swallow-nonspecific (expiratory muscle strength training [EMST]) swallow therapy task in order to examine the differential effects of each on hyoid motion and associated submental activation in healthy adults, with the overall goal of characterizing task-specific and overload properties of each task.Method: Twenty-five healthymale and female adults (M=25 years of age) participated in this prospective, experimental study with 1 participant group. Each participant completed all study tasks (including normal swallow, Mendelsohn maneuver swallow, effortful swallow, and EMST task) in random order during concurrent videofluoroscopy and surface electromyography recording.Results: Results revealed significant differences in the trajectory of hyoid motion as measured by overall displacement and angle of elevation of the hyoid bone. As well, timing of hyoid movement and amplitude differences existed between tasks with regard to the activation of the submental musculature.dConclusions: Study results demonstrated differential effects of the 3 experimental tasks on the principles of task specificity and overload. These principles are important in the development of effective rehabilitative programs. Subsequent direction for future research is suggested.
