假设。气功锻炼是一种流行的方法，可以缓解乳腺癌幸存者传统癌症治疗的副作用，但其效果尚未得到实证评估。本研究旨在探讨气功锻炼对乳腺癌及乳房切除术后存活者上肢淋巴水肿、动脉阻力及血流速度的影响。研究设计。这项研究是作为前瞻性临床试验进行的。方法：研究方法。有气功经历的乳腺癌患者11例(平均年龄58.3±/-10.1岁)为试验组，无气功经历的乳腺癌患者12例(平均年龄53.8±/-4.2岁)为对照组。他们都患有乳腺癌相关的淋巴水肿。所有程序在一次会议内完成。基线测量后，实验组进行18种太极拳内气功练习，时间约为6分钟，对照组以坐姿休息约6分钟。然后，两组人都接受了重新评估。所有参与者都被测量了他们受影响的上肢周长(使用卷尺)、外周动脉阻力和血流速度(使用多普勒超声仪)。结果。在基线的所有结果指标上，组间差异均不显著(P>；0.05)。气功锻炼后患侧上臂、肘部、前臂、腕部周长减小(P<；0.05)。然而，两组在后测的周长方面没有发现显著差异(P>；.0125)。在血管结果方面，气功锻炼后阻力指数显著降低，最大收缩动脉血流速度(SV)和最小舒张期动脉血流速度(DV)显著升高(P<；0.05)。组间差异对于SV接近显著(P=.018)，对于DV(P<；.001)后测显著。结论。气功锻炼可以减少乳腺癌幸存者的传统癌症治疗副作用，如上肢淋巴水肿和循环状况不佳。然而，这种影响可能是暂时的，必须进行进一步的研究，以探索更长期的影响。
Hypothesis. Qigong exercise is a popular method for relieving the side effects of conventional cancer treatments in survivors of breast cancer, yet its effects are not empirically assessed. This study aimed to investigate the effects of qigong exercise on upper limb lymphedema, arterial resistance, and blood flow velocity in survivors with breast cancer and mastectomy. Study Design. This study was conducted as a prospective clinical trial. Methods. Eleven survivors of breast cancer with qigong experience (mean age = 58.3 +/- 10.1 years) were assigned to the experimental group and 12 survivors of breast cancer without qigong experience (mean age = 53.8 +/- 4.2 years) were assigned to the control group. They all had breast cancer-related lymphedema. All procedures were completed within one session. After baseline measurements were taken, the experimental group performed 18 Forms Tai Chi Internal Qigong for approximately 6 minutes while the control group rested for similar duration in a sitting position. Both groups were then reassessed. All participants were measured on their affected upper limb circumference (by using tape measures), peripheral arterial resistance, and blood flow velocities (using a Doppler ultrasound machine). Results. The between-group differences were not significant for all outcome measures at baseline (P > .05). The circumferences of the affected upper arm, elbow, forearm and wrist decreased after qigong exercise (P < .05). However, no significant difference was found in the circumference measures between the 2 groups posttest (P > .0125). In terms of vascular outcomes, the resistance index decreased and the maximum systolic arterial blood flow velocity (SV) and minimum diastolic arterial blood flow velocity (DV) increased significantly after qigong exercise (P < .05). The between-group difference was close to significant for SV (P = .018) and was significant for DV (P < .001) posttest. Conclusion. Qigong exercise could reduce conventional cancer therapy side effects such as upper limb lymphedema and poor circulatory status in survivors of breast cancer. However, such effects may be temporary, and further studies must be conducted to explore longer term effects.
