This study aims to investigate the effects of craniocervical flexion (CCF) on the activation of suprahyoid and sternocleidomastoid (SCM) muscles in Shaker and Resistant Jaw Opening (RJO) exercises, and to compare the effects of these two exercises on the same muscles with the Chin Tuck Against Resistance (CTAR) exercise. The study recruited a total of 37 healthy participants (20 female and 17 male, mean age: 27.45 ± 7.32 years). All participants received craniocervical flexion training with the biofeedback pressure unit (Stabilizer™, Chattanooga Group Inc. USA). Shaker, Shaker with CCF, RJO, RJO with CCF and CTAR exercises were performed and surface electromyographic (sEMG) activations of the suprahyoid and SCM muscles were recorded. In addition, the maximum sEMG activations of suprahyoid and SCM muscles were recorded for the normalization procedure. CCF increased the effect of Shaker exercise on the suprahyoid muscle activation (p < 0.001); but this effect was not seen in RJO exercise (p > 0.05). Suprahyoid muscle activation was lower in Shaker exercise compared to RJO and CTAR exercises (p < 0.016). SCM muscle activation was greater in CTAR exercise compared to Shaker and RJO exercises (p < 0.016). The addition of CCF to the Shaker and RJOE exercises did not affect the ranking among the three exercises for both the suprahyoid and SCM muscles. The result of this study suggest that integration of CCF movement to the Shaker exercise would have a greater therapeutic effect. In addition, RJO exercise can be included in the rehabilitation program as an alternate to CTAR exercise.
本研究旨在探讨在 Shaker 和 Resistant Jaw Opening（RJO）运动中，头颈部前屈（CCF）对舌骨上和胸锁乳突肌（SCM）肌肉激活的影响，并比较这两种运动与 Chin Tuck Against Resistance（CTAR）运动对同一肌肉的影响。研究共招募了 37 名健康参与者（20 名女性和 17 名男性，平均年龄：27.45±7.32 岁）。所有参与者均接受了生物反馈压力单元（Stabilizer™， Chattanooga Group Inc. USA）的头颈部前屈训练。进行了 Shaker、CCF 下的 Shaker、RJO、CCF 下的 RJO 和 CTAR 运动，并记录了舌骨上和 SCM 肌肉的表面肌电图（sEMG）激活。此外，还记录了舌骨上和 SCM 肌肉的最大 sEMG 激活值以进行归一化处理。CCF 增加了 Shaker 运动对舌骨上肌激活的影响（p<0.001）；但在 RJO 运动中未观察到这种影响（p>0.05）。与 RJO 和 CTAR 运动相比，Shaker 运动中舌骨上肌的激活较低（p<0.016）。与 Shaker 和 RJO 运动相比，CTAR 运动中 SCM 肌肉的激活更大（p<0.016）。将 CCF 添加到 Shaker 和 RJOE 运动中不会影响这三种运动对舌骨上和 SCM 肌肉的影响的排名。本研究结果表明，将 CCF 运动整合到 Shaker 运动中会产生更大的治疗效果。此外，RJO 运动可以作为 CTAR 运动的替代方案纳入康复计划。
