About
This is a retrospective registration of a study that evaluated whether a traditional Dao-yin (mind-body exercise), called Shangshou Dao-yin, could improve sleep quality, Chinese medicine body constitution, and quality of life in breast cancer patients receiving adjuvant chemotherapy.
A total of 327 postoperative breast cancer patients completed baseline questionnaires. Among them, 150 eligible participants entered the trial and were assigned to either a Dao-yin exercise group (72 participants) or a control group (78 participants) based on their preference. The exercise group practiced 20 minutes of Shangshou Dao-yin daily throughout chemotherapy, while the control group received standard care only. After withdrawals, 138 participants completed the final evaluation (66 in the Dao-yin group and 72 in the control group).
Sleep quality, body constitution (BCQ), quality of life (EORTC), and chemotherapy-related adverse effects were assessed during treatment and three weeks after chemotherapy completion. The findings may help determine whether Shangshou Dao-yin can reduce sleep disturbance and enhance well-being during cancer treatment.
Full description
Breast cancer remains one of the most prevalent malignant diseases among women, and many patients receiving adjuvant chemotherapy experience sleep disturbance, emotional distress, fatigue, and impaired quality of life.
Shangshou Dao-yin is a traditional Dao-yin (mind-body exercise) consists of eight techniques: Bouncing, Rotation, Swaying, Swinging, Wobble, Chopping, and Abdominal (diaphragmatic) Breathing. The core principle of the Shangshou Dao-yin method is to stimulate the lower dantian, the body's source of vital energy. Dao-yin emphasizes mental focus, natural breathing, and smooth, continuous movements that follow the body's structure to harmonize internal energy flow. It requires no equipment and minimal space, making it particularly suitable for patients during chemotherapy.
This retrospective registration describes a study that evaluated whether Shangshou Dao-yin could improve sleep quality, Chinese medicine body constitution, and health-related quality of life in breast cancer patients undergoing adjuvant chemotherapy. The study was approved by the Institutional Review Board of Tri-Service General Hospital (TSGHIRB-1-105-05-045) and was conducted between January 2017 and October 2019.
A total of 327 postoperative breast cancer patients completed baseline questionnaires. Among them, 150 eligible participants entered the trial and were assigned, based on preference, to either a Shangshou Dao-yin group (n = 72) or a control group (n = 78). The Dao-yin group practiced 20 minutes of Shangshou Dao-yin daily throughout chemotherap. A standardized instructional video, provided on DVD and through online streaming (e.g., YouTube) in collaboration with the Taiwan Society of Health Promotion. The control group received standard care only. After withdrawals, 138 participants (66 Dao-yin, 72 control) completed the final evaluation.
Data collection included baseline characteristics (age, sex, height, weight, marital status, education level, smoking and alcohol history, medical history, family history, pregnancy and childbirth history, food or drug allergies, and comorbidities). Cancer-related variables included TNM stage, surgical method, tumor histology, differentiation, hormone receptor status, and HER2 expression. Chemotherapy-related information included regimen, dosage, treatment cycles, dose modifications, delays, and completion of planned cycles.
Multiple clinical assessments were performed. Sleep quality was measured using the Chinese version of the Pittsburgh Sleep Quality Index (PSQI). Chinese medicine body constitution was assessed using the 44-item Body Constitution Questionnaire (BCQ), which measures Yang-Xu, Yin-Xu, and Stasis constitutions. Health-related quality of life was evaluated using the EORTC QLQ-C30 and QLQ-BR23. Psychological status was measured using the Beck Anxiety Inventory (BAI) and Beck Depression Inventory-II (BDI-II). Laboratory monitoring included white blood cell count, granulocyte and lymphocyte percentages, platelet count, hemoglobin, liver and kidney function tests, and electrolytes.
Chemotherapy-related adverse effects were documented according to the Common Terminology Criteria for Adverse Events (CTCAE v4.0), including hematologic changes, infection, gastrointestinal symptoms (nausea, vomiting, diarrhea, abdominal bloating), mucositis, neuropathy, skin pigmentation, and insomnia. Medication use was recorded, including supportive drugs for chemotherapy side effects, chronic disease medications, and complementary therapies such as Chinese herbal medicine or special diets. Unscheduled outpatient visits, emergency department visits, hospitalizations, and physician-directed management of serious toxicities (dose reduction, treatment delay, or discontinuation) were also documented.
Assessments were performed before chemotherapy, at scheduled 4 time points during treatment, and three weeks after completion of chemotherapy. This study may help determine whether a traditional mind-body exercise can be feasibly implemented as a supportive care strategy for breast cancer patients undergoing chemotherapy.
