Tai Chi as Effective as Physical Therapy for Knee Osteoarthritis

Tai Chi is at least as effective as physical therapy for treating knee osteoarthritis, according to a randomized trial in the Annals of Internal Medicine.
Some 200 adults aged 40 or older with knee osteoarthritis were randomized to Tai Chi or physical therapy. Tai Chi included two group sessions weekly for 12 weeks, while physical therapy involved two outpatient sessions weekly for 6 weeks followed by continued home exercises for 6 weeks.
At 12 weeks, both groups saw significant reductions in a 500-point osteoarthritis index measuring pain (mean decreases of 167 points with Tai Chi and 143 with physical therapy); the difference between groups was not significant. The Tai Chi group had significantly greater improvements in depression and quality-of-life scores. In both groups, treatment effects persisted to 52 weeks.
The authors conclude that "standardized Tai Chi should be considered as an effective therapeutic option for knee osteoarthritis."
