摘要

The cervical traction is often used for patients with cervical disease, but it is high-risk treatment for them with cardiovascular disease. The purpose of this study was to investigate the normal young women in 10%, 20%, and 30% body weight (BW) of cervical traction and to observe the autonomic nervous activity and blood pressure changes. Twenty-nine healthy female volunteers (age: 20.58±1.58 years. weigh: 48.54±5.86 kg) were divided into A group (n=10, traction weight: 10% BW), B group (n=10, traction weight: 20% BW) and C group (n=9, traction weight: 30% BW). Heart rate (HR) and blood pressure (BP) were measured by manometer: The hand-held electrocardiogram (ECG) was used to measure ECG signals that were analyzed by signal processing. In time domain analysis, the standard deviation of normal-to-normal intervals (SDNN) indicated heart rate variability (HRV). In frequency domain analysis, high frequency (HF), low frequency (LF) and LF/HF ratio meant the autonomic nervous activity and balance. Volunteers were administered for 20-minute neck traction, and all parameters were measured before and after traction. The result was showed that systolic and diastolic BP. and HF were increased (p＜0.05), but HR and HRV were decreased (p＜0.05) in C group during the traction. We found that 30% BW of cervical traction was adventurous dosage and suggested to be careful in clinical treatment for in particular the patients with cardiovascular disease.
