几种运动方法，如Shaker练习，舌头按压练习，下巴收紧对抗阻力（CTAR）练习和下颌下推练习，已被引入以加强与吞咽有关的肌肉。在这项研究中，我们比较了CTAR的有效性，下颌下推，和振动练习诱导选择性的上和下舌骨肌收缩使用表面肌电图（EMG）。本研究为前瞻性非随机对照研究。入组了25名健康受试者和20名吞咽困难患者。在三种不同类型的运动中，使用表面肌电图分析胸锁乳突肌（SCM）、舌骨上肌（二腹肌和下颌舌骨肌的前腹）和舌骨下肌（胸骨甲状肌和甲状舌骨肌）的均方根（RMS）值。采用单因素重复测量方差分析方法分析三种不同运动方式下吞咽肌活动的差异。就舌骨上肌的最大和平均RMS值而言，在健康受试者中，下颌下推运动显示出比CTAR和Shaker运动更大的RMS值（p < 0.05）。在吞咽困难患者中，就舌骨上肌的最大RMS值和平均RMS值而言，Shaker运动和颌下推动运动显示出比CTAR运动更大的RMS值（p < 0.05）。下颌下推运动可能是有效的吞咽肌肉锻炼，由于其优越性，在诱导选择性收缩的上和下舌骨肌肉。CTAR和Shaker练习在这方面也很有效。
Several exercise methods, such as the Shaker exercise, tongue press exercise, chin tuck against resistance (CTAR) exercise, and submandibular push exercise, have been introduced to strengthen the muscles involved in swallowing. In this study, we compared the effectiveness of the CTAR, submandibular push, and Shaker exercises for the induction of selective supra- and infrahyoid muscle contractions using surface electromyography (EMG). This study is a prospective non-randomized controlled study. Twenty-five healthy subjects and 20 patients experiencing swallowing difficulty were enrolled. During the three different types of exercises, the root mean square (RMS) values of the sternocleidomastoid (SCM), suprahyoid (anterior belly of the digastric and mylohyoid muscles), and infrahyoid (sternothyroid and thyrohyoid muscles) muscles were analyzed using surface EMG. Differences in the activity of swallowing muscles among the three different exercises were analyzed using one-way repeated measured analysis of variance. In terms of both the maximum and mean RMS values of the suprahyoid muscle, the submandibular push exercise showed a larger RMS value than the CTAR and Shaker exercises in healthy subjects (p < 0.05). In terms of both the maximum and mean RMS values of the suprahyoid muscle, the Shaker exercise and submandibular push exercise showed a larger RMS value than the CTAR exercise in patients with swallowing difficulty (p < 0.05). The submandibular push exercise may be effective as a swallowing muscle exercise owing to its superiority in inducing selective contractions of the supra- and infrahyoid muscles. The CTAR and Shaker exercises are also effective in this regard.
