PURPOSE The purpose of this study was to explore the experiences of Tai Chi in women with osteoarthritis. METHODS Data were collected by face-to-face interview from 14 participants. Theoretical sampling was performed until the concepts were saturated. The main question was "How do you describe your experience of Tai Chi?" Data were analyzed using a grounded theory methodology. All interviews were audio taped and transcribed verbatim. RESULTS The Phenomenon is 'QI flowing'. The core category was identified with 'inspiring one's life with strength'. This series of processes was categorized into four stages: 'Challenging Tai chi', 'Doing one's best', 'Deplenishing (the word used in English and Tai chi is emptying one's mind) one's mind', 'Taking a Positive view of life'. CONCLUSION The finding of this study will offer profound understanding about the reported tai chi's experience. Additional research should be done as to the role of Tai chi as a nursing intervention strategy for osteoarthritis patients.
