Tai-Chi Exercise Reduces Fatigue in Breast Cancer Patients Undergoing Chemotherapy

Tai-Chi Exercise Reduces Fatigue in Breast Cancer Patients Undergoing Chemotherapy.

The main question it aims to answer is: Does Tai-chi training reduce fatigue in breast cancer patients? Participants performed the exercise on the day agreed upon with the researcher. All participants were given routine care, and leaflets related to chemotherapy, psychological aspects of cancer patients, nutrition, and management of cancer symptoms. While respondents in the intervention group received 5 times Tai-Chi practice interventions in a week for 3 weeks with a duration of 30 minutes of each practice, using 18 forms of Tai-Chi shibashi adapted from Yang's style. Before the Tai-Chi intervention is implemented, standard training was given once to each respondent by an experienced Tai-Chi master, as well as video tutorials for independent practice at home demonstrated by the Tai-Chi master.

During the three weeks of practicing Tai-Chi at home, each respondent was asked to fill out a logbook for each exercise, and fill out a fatigue questionnaire every three days, while the control group was asked to fill out their daily physical activities reports on the logbook. The researcher invited the intervention group respondents to the WhatsApp Group to remind the participants to practice the Tai-Chi exercise at home every day, evaluate side effects during exercise and fill out a fatigue questionnaire in the logbook. The researcher also invited control group respondents to the WhatsApp Group to remind participants to fill in their daily physical activities and fill out fatigue questionnaires in the logbook.

Research respondents who met the inclusion criteria were randomized by research assistants using block randomization with sorted random tables, the order of randomization was kept by research assistants who were not directly involved in the study. After the respondents who met the requirements were identified and completed the pre-test, the researcher contacted the research assistant to place the respondents in the intervention or control group according to a pre-determined randomization sequence. Due to the observable nature of Tai-Chi practice, the lack of a sham comparison group, and the pre-test and post-test measurements reported by the respondents, blindness could not be performed on the respondents. Data collection and follow-up is carried out every 3 days via chat or telephone. Based on the initial sample count, there were 23 respondents in each group (n = 46), and to cover the possibility of 25% drop-out respondents, the correction for the sample size of this study was 61 respondents, 31 respondents in the intervention group, 30 respondents in the control.
