A study carried out at Harvard University in 2006 showed that those who did tai chi improved more than 30% in lower-body strength and 25% in arm strength - almost as much as those who participated in resistance training, and more than those assigned to brisk walking.
A study in 2008 at Tufts University, Boston found that regular tai chi practice reduced pain and improved mood and physical functioning more than standing stretching exercises in people with severe knee osteoarthritis. Another study in Korea confirmed that tai chi training significantly improved flexibility and slowed the disease process in patients with ankylosing spondylitis, a painful form of arthritis that affects the spine.
The University of Rochester found that quality of life and functional capacity was improved in woman suffering from breast cancer or the side effects of breast cancer treatment, as a result of practicing tai chi.
A study at Taiwan University showed that a year's study of tai chi significantly boosted exercise capability, lowered blood pressure, and improved levels of cholesterol, triglycerides, insulin, and C-reactive protein in people at high risk for heart disease.
A pilot study on the benefits of tai chi at Harvard Medical School reported an improved ability to walk and quality of life. It also reduced blood levels of B-type natriuretic protein, an indicator of heart failure.

Researchers at the University of California studied the effects of tai chi on resting and vaccine-stimulated levels of cell-mediated immunity to the varicella zoster virus and on health functioning in older adults.

Researchers in Taiwan carried out a case-control study of 30 pairs of type 2 diabetics to investigate the effects of a 12-week course in tai chi exercise on T cell helper reaction in type 2 diabetics. After 12-weeks of tai chi the tai chi group had decreased HbA1c levels and increased T cell helper reaction. This indicates that a combination of tai chi along with medication may be beneficial both to metabolism and immunity in type 2 diabetics.
