Callahan (2009) conducted a study to evaluate the effectiveness of physical exercise programs for individuals with chronic arthritis. Participants with doctor-diagnosed arthritis either received a Tai Chi course immediately or were placed in a control group to begin the course 8 weeks later. At the end of the 8-week period, self-reports of pain were obtained for both groups. Data similar to the results obtained in the study are shown in the following table.
Self-Reported Level of Pain | ||
Mean | SE | |
Tai Chi course | 3.7 | 1.2 |
No Tai Chi course | 7.6 | 1.7 |
