The aim of the study was to investigate the difference in response to a motor imagery task between individuals with and without painful temporomandibular disorders (TMDs). The participants were 24 adults with and without TMD (TMD and control group, resp.). A set of photographic images of the profile view of a person's head and neck and a hand and a foot were presented in a random order. The set consisted of six different orientations with rotations of each image at 0, 60, 120, 180, 240, and 300 degrees and included left and right representations. The participants were required to view the image and make a decision as to whether it was a left or a right side presented, that is, mental rotation (MR) task. Data were collected on 48 tasks (including left and right) at each orientation for each body part. Reaction times (RTs) for correct answers and accuracy in making the left or right judgements were recorded. The RT was slower in the TMD group than in the control group. The RT for the profile image was slower than those for the hand and foot images. For images that were 180 degrees, the RT was slower and the accuracy was lower than those for five of the other image orientations. The judgements made about the 180-degree rotated image were more inaccurate compared to images of all other orientations among all types of stimuli.
该研究的目的是调查患有和未患有疼痛性颞下颌关节紊乱症（TMD）的个体在对运动想象任务的反应上的差异。参与者为24名患有和未患有TMD的成年人（分别为TMD组和对照组）。一组人物头部和颈部侧面视图以及一只手和一只脚的照片图像以随机顺序呈现。该组图像包含六种不同的方向，每个图像分别旋转0、60、120、180、240和300度，且包括左右视图。参与者被要求观看图像并判断其呈现的是左侧还是右侧，即心理旋转（MR）任务。针对每个身体部位的每个方向收集了48项任务（包括左右）的数据。记录正确答案的反应时间（RTs）以及做出左右判断的准确性。TMD组的反应时间比对照组慢。侧面图像的反应时间比手和脚图像的反应时间慢。对于180度的图像，其反应时间比其他五个图像方向的反应时间慢，准确性也更低。在所有类型的刺激中，与所有其他方向的图像相比，对180度旋转图像做出的判断更不准确。
