Usual Care only. Usual care is defined as the care these subjects would like to seek from any health care practitioner or other program they may seek for healthy living. The subjects in this arm will be offered the AF Tai Chi intervention after an 8 week followup data collection

Usual care plus Tai Chi. These subjects will be allowed to seek care from any health practitioner or any other programs and will receive the AF Tai Chi program for 8 weeks.

The primary goal of this study is to assess the effectiveness and feasibility of the arthritis foundation (AF) Tai Chi Program for People with Arthritis. Arthritis, the most prevalent chronic condition in the US and a leading cause of disability, is characterized by chronic pain and progressive impairment of joints and soft tissues. Promoting physical activity is a key public health strategy to addressing arthritis management, but more scientific data regarding effectiveness and feasibility are need to support the promotion of the AF Tai Chi Program as an exercise intervention for people with arthritis. Participants will be randomly assigned to the intervention or delayed control arm of the study.

Arthritis symptoms include pain, stiffness and fatigue as measured using a 10 cm Visual Analog Scale (VAS)

The disability scale of the HAQ will be used to assess physical functioning and disease progression. As a disease specific measure it is used in much of the rheumatological literature. It includes items querying 20 specific activities of daily living in 8 domains (dressing, arising, eating, walking, hygiene, activities, ready, grip) and adjusts scores based on the use of assistive devices. The HAQ is scored from 0 to 3, with 0 representing no disability and 3 representing maximum disability.

Self-efficacy for managing arthritis will be assessed using two subscales from the Arthritis Self Efficacy Scale developed by Lorig and colleagues. The scale assess the degree to which an individual feels confident about his or her ability to manage his or her arthritis including decreasing pain, keeping pain from interfering with normal activities, and dealing with frustration of having arthritis. The pain subscale (5 items) and the other symptoms subscale (6 items) will be used. The items are scored on a Likert-type scale with 0= "very uncertain" and 100= "very certain"

Adapting a previously used method to the particular schedule of this protocol, both intervention and control participants will be given a "falls calendar" at baseline and instructed to record each day for 16 weeks if they had a fall. Falls are defined as "unintentially coming to rest on the floor or ground". This record will cover the intervention group through the 8 week Tai Chi course and or an 8 week follow up period. The control group record will cover the 8 weeks before Tai Chi and during the delayed Tai Chi course. The calendars will be mailed in after completion.

Psychosocial measures include: Rheumatology Attitudes Index (RAI, helplessness)
