Chronic geriatric pain is defined as an unpleasant sensory and emotional experience affecting persons who are over 65 years old for more than 3 months, which is associated with actual and potential tissue damage, or described in terms of such damage, and which is non-cancerous in nature [1]. In Hong Kong, 37%-50% of community-dwelling older adults suffer from chronic pain [2,3], with the prevalence being as high as 70% among nursing home residents [4]. Chronic pain has a severe impact on older adults, as it can hinder their activities of daily living and lead to depression and anxiety, decreased social interaction, impaired mobility and falls, sleep disturbances, malnutrition and, ultimately, an increase in health care utilization and expenditures [5]. Given this current burden, innovative and cost-effective ways of managing chronic pain should be developed
