Qigong for Breast Cancer Survivors
Randomised Controlled Trial of Qigong Training Programme to Alleviate Arm Oedema, ¬Reduce Shoulder Impairment, Improve Body Balance and Quality of Life in Community-dwelling Breast Cancer Survivors
Objectives: (1) To investigate the effects of Qigong training on upper limb oedema, circulatory status, shoulder flexibility and muscular strength, body balance, and quality of life (QOL) in community-dwelling breast cancer survivors; and (2) to explore the relationship between the impairment outcomes and QOL outcomes.
Hypothesis: (1) The experimental participants will have less impairment and a better QOL after Qigong training compared with the no-training control group; and (2) the impairment parameters will be related to the QOL indexes in the Qigong participants.
Design and subjects: This will be a prospective, randomised, single-blinded controlled trial. Approximately 60 breast cancer survivors will be randomly assigned to either the Qigong training group (n~30) or control group (n~30).
Intervention: Participants in the Qigong group will receive 18 Forms of Tai Chi Internal Qigong training for 3 months with two supervised 1-hour sessions per week.
Main outcome measures: The primary outcome measures are upper limb circumference, arterial blood flow velocities and resistance index, shoulder joint passive range of motion, muscular strength (peak force) and body balance. The secondary outcome measure is quality of life as measured by the Functional Assessment of Cancer Therapy - Breast scale.
Data analysis: Data will be analysed via repeated-measures analysis of variance followed by post-hoc tests (α = 0.05).
Expected results: The investigators pilot studies produced encouraging results on the efficacy of Qigong exercise in reducing chronic breast cancer-related symptoms in survivors. Therefore, the investigators expect that participants in the Qigong group will have fewer upper limb impairments and a better quality of life after Qigong training. If the results are positive, this Qigong training regime is readily transferrable to clinical practice, and could have positive socioeconomic effects such as reduced healthcare costs.

Experimenteel: Qigong training group
Participants assigned to the Qigong group will receive Qigong training.
The Qigong training programme will be run for 3 months with two supervised 1-hour sessions per week.
Participants will learn the 18 Forms of Tai Chi Internal Qigong.
The training sessions will be conducted by a qualified Qigong instructor from the Natural Health Qigong Association.
Participants in the control group will receive no Qigong training during the study period.
They will receive an 18 Forms of Tai Chi Internal Qigong training package after the study.
