OBJECTIVE: To evaluate the effects of Tai Chi
Qigong training on the quality of life and physical function of patients with
osteoarthritis of the knee.Design: A preliminary,
single-blind, randomized controlled trial.
SETTING: General community, performed at Hwaseong
PARTICIPANTS: Forty-four elderly subjects (mean
age, 69.1 +/- 5.4 years) with knee osteoarthritis.Intervention:
The patients were randomized (2:1) to: (1) an eight-week Tai Chi Qigong
training programme or (2) a waiting list control
group. The programme involved eight weeks of group
Tai Chi Qigong sessions, with 60 minutes per session twice a week.Main outcome measures: The primary outcome was quality
of life measured with the Short Form 36 (SF-36) at baseline and week 8.
Secondary outcomes included the Western Ontario
and McMaster University Osteoarthritis Index (WOMAC) and 6-m walking time.
RESULTS: The training group had
statistically significant improvements in the quality of life (changes of
SF-36, Qigong versus control: 21.6 +/- 16.8 versus 9.8 +/- 13.6, P < 0.05)
and 6-m walking test (change in walking time, Qigong versus control: -1.6 +/-
1.7 versus -0.2 +/- 0.8 s, P < 0.01). The WOMAC scores in the training group
were markedly improved, although the differences were not statistically
CONCLUSIONS: Tai Chi Qigong training appears to
have beneficial effects in terms of the quality of life and physical
functioning of elderly subjects with knee osteoarthritis. However, more
rigorous trials are needed to confirm the efficacy of this training for patients
with osteoarthritis of the knee.
