    ObjectiveThis was a secondary data analysis of a cluster-randomized clinical trial that tested the efficacy of a 20-week Sun-style Tai Chi (TC) program in reducing pain in community-dwelling elders with cognitive impairment and knee osteoarthritis (OA). The study also examined whether elders' level of cognitive function was related to the outcomes of the TC program.MethodElders (N=55) were recruited from 8 study sites. Each site was randomly assigned to participate in either a 20-week TC or an education program. Verbal report of pain was measured by a Verbal Descriptor Scale (VDS) at weeks 1, 5, 9, 13, 17 and 21 (designated as times 1-6). Pain behaviors and analgesic intake were also recorded at times 1-6.ResultsAt post-test, scores on the VDS and observed pain behaviors were significantly better in the TC group than in the control group (p=0.008-0.048). The beneficial effects of TC were not associated with cognitive ability.ConclusionThese results suggest that TC can be used as an adjunct to pharmacological intervention to relieve OA pain in elders with cognitive impairment.Trial RegistrationClinical Trial.gov NCT01528566.Copyright © 2015 Elsevier Ltd.
