Cervical traction is a physical therapy procedure frequently used to treat cervical disk lesions, cervical spondylosis, and cervical facet joint lesions. We have observed rare cases of side effects in elderly patients, but not in women younger than 30 years.In this pilot study, 96 young women were randomly divided into 3 groups to study the effect of cervical traction with different traction weights on blood pressure, heart rate, heart rate variability, and correlated autonomic adjustment. Cervical traction weight used was 10% of the patient's body weight in group A (n=32), 20% in group B (n=32), and 30% in group C (n=32). Assessments of blood pressure, heart rate, heart rate variability, percentage of high- and low-frequency signals, and low-frequency/high-frequency ratio were performed before, during, and 20 minutes after traction. We found that systolic blood pressure, diastolic blood pressure, and heart rate variability elevated during cervical traction and returned nearly to original levels immediately after traction in group C, but not in groups A or B. There were no significant changes in heart rate, percentage of high- or low-frequency signals, and low-frequency/high-frequency ratio in all 3 groups during or after cervical traction.Cervical traction with a traction weight approximately 10% to 20% of body weight can be safely provided without significant compromise of cardiovascular function. However, heavy traction weight (30% of body weight) should be avoided, especially for a patient with cardiovascular disease.
颈椎牵引是一种常用于治疗颈椎间盘病变、颈椎病和颈椎小关节病变的物理治疗方法。我们观察到老年患者中罕见有副作用的病例，但30岁以下女性中未出现。在这项初步研究中，96名年轻女性被随机分为3组，以研究不同牵引重量的颈椎牵引对血压、心率、心率变异性及相关自主神经调节的影响。A组（n = 32）使用的颈椎牵引重量为患者体重的10%，B组（n = 32）为20%，C组（n = 32）为30%。在牵引前、牵引期间和牵引后20分钟对血压、心率、心率变异性、高频和低频信号百分比以及低频/高频比值进行评估。我们发现，C组在颈椎牵引期间收缩压、舒张压和心率变异性升高，牵引后立即几乎恢复到原始水平，但A组和B组未出现这种情况。在所有3组中，颈椎牵引期间及牵引后心率、高频或低频信号百分比以及低频/高频比值均无显著变化。使用约为体重10%至20%的牵引重量进行颈椎牵引可安全进行，而不会对心血管功能造成显著损害。然而，应避免使用重的牵引重量（体重的30%），尤其是对患有心血管疾病的患者。
