简要总结
Upper Crossed Syndrome (UCS) is a pattern of muscle imbalance that leads to forward head posture, rounded shoulders, or excessive thoracic kyphosis, thereby affecting posture and cervical-shoulder function. Dynamic Taping is a taping technique aimed at enhancing movement control and muscle support through its elastic material and tension, influencing the skin and neuromuscular system. When applied to UCS patients, Dynamic Taping can assist in posture correction, improve posture control, and increase scapular dynamic stability. Additionally, Dynamic Taping can enhance proprioception, helping patients maintain proper posture through sensory feedback. Corrective exercises improve posture and stability by strengthening weakened muscles and stretching tight muscles. Combining these two interventions is expected to help address poor posture.
详细描述
This study aims to investigate the effects of Dynamic Taping combined with corrective exercises on cervical proprioception and muscle imbalance in UCS patients. A two-factor repeated measures ANOVA will be used to evaluate the effects before and after the intervention.
Participants recruited for this study must be adults aged 20 years or older. The study will evaluate their posture, including craniovertebral angle (CVA), sagittal shoulder angle (SSA), thoracic kyphosis angle, subacromial space, coracoid-humeral distance (CHD), cervical proprioception, muscle strength (deep cervical flexors, upper, middle, and lower trapezius, serratus anterior, rhomboid muscles), and electromyographic (EMG) to evaluate muscle activation (upper, middle, and lower trapezius, serratus anterior).

研究组 & 干预措施
Combined Dynamic Taping and Corrective Exercise (DT+EX Group)
Participants in this group received postural taping using dynamic tape aimed at correcting forward head posture, rounded shoulders, and thoracic kyphosis. The tape was worn continuously throughout the intervention period, 24 hours a day. It was reapplied if participants reported detachment; otherwise, it was replaced every three days. In addition to taping, participants performed a corrective exercise program based on the NASM Corrective Exercise Continuum, which included four phases: inhibit, lengthen, activate, and integrate. The intervention lasted for three weeks, with 3 to 4 sessions per week, totaling 10 training sessions. Each session lasted approximately 60 to 75 minutes.

Dynamic Taping (DT Group)
Participants in this group received postural taping using dynamic tape aimed at correcting forward head posture, rounded shoulders, and thoracic kyphosis. The taping method was identical to that used in the DT + EX group. The tape was worn continuously throughout the intervention period, 24 hours a day. It was reapplied if participants reported detachment; otherwise, it was replaced every three days. The intervention lasted for three weeks. No corrective exercise intervention was provided to this group.

结局指标
主要结局
Posture (CVA and SSA and Kyphosis Angle)
时间窗: Participants were assessed at time points: prior to the intervention (baseline), immediately three weeks after the intervention, and at a one-month follow-up.
The craniovertebral angle (CVA) and shoulder sagittal angle (SSA) were measured using the Physiomaster mobile application. During the measurement, the examiner positioned the smartphone to align the subject's image with the vertical and horizontal reference lines on the screen and then captured a photograph. The anatomical landmarks used for angle determination included the lateral canthus of the eye, the tragus of the ear, the spinous process of the seventh cervical vertebra (C7), and the midpoint of the line connecting the acromial processes. The thoracic kyphosis angle was measured using the Angle Meter mobile application. First, the device was calibrated to 0°. The smartphone was then placed at the level just inferior to T1 and subsequently at the level superior to T12. The kyphosis angle was calculated by summing the two measured angles.
Cervical Proprioception
时间窗: Participants were assessed at time points: prior to the intervention (baseline), immediately three weeks after the intervention, and at a one-month follow-up.
Cervical proprioception was assessed using the Head Repositioning Accuracy (HRA) test with a cervical range of motion (CROM) device. Participants were instructed to adopt and recognize the neutral head position (0°). The head was then passively guided to 30° of flexion, extension, lateral flexion, and rotation. After each movement, participants actively returned to the perceived neutral position under both eyes-open and eyes-closed conditions. The repositioning error was defined as the angular difference between the actual and the perceived 0° position
