To compare the effectiveness of different nonpharmacological interventions on pain relief in older adults with osteoarthritis, literature databases, bibliographies, and other relevant sources were searched. No language limitations were applied. Thirty-two trials published from 1997 to 2017 were included in the systematic review and network meta-analyses. We included only randomized controlled trials and studies that evaluated the effects of nonpharmacological interventions on alleviating pain in elderly adults (age ≥60 yrs or mean age > 65 yrs) who experience osteoarthritis, irrespective of sex. In the network meta-analysis, resistance training was ranked as the most effective among all nonpharmacological interventions (surface under the cumulative ranking = 82.9%, standardized mean difference = 1.96, confidence interval = -1.39 to 5.31). In subgroup analyses, resistance training still ranked the most effective pain reduction intervention, followed by strengthening exercise and yoga. Among female subjects with intervention adherence rate more than 90%, the most effective intervention was yoga. Strengthening exercise was superior to all other forms of interventions when comparing long-term effect of selected interventions. Among older adults with osteoarthritis, resistance training can be considered a treatment option for pain relief. Yoga is an effective intervention strategy for female elderly, and strengthening exercise has a better long-term beneficial effect.
