Background: Elderly people are particularly vulnerable to COVID-19, especially those with underlying illnesses. Additionally, a study discovered that SARSCoV-2 infection is more frequently linked to negative outcomes in the elderly population than in younger age groups. Given the potential adverse effects of long-term anxiety on overall well-being, it is crucial to explore effective non-pharmacological interventions to alleviate anxiety symptoms. Aim: This pre-experimental study aims to investigate the effectiveness of Jacobson relaxation techniques in reducing anxiety levels among post-COVID geriatric individuals with comorbid illnesses. Subjects and Methods: The study utilizes a pre-test/post-test design without a control group. The 41 participants had undergone a relaxation intervention based on Jacobson's progressive muscle relaxation technique for duration of about 1 week. Anxiety levels will be measured using standardized anxiety scale, Hamilton anxiety scale before and after the intervention. Result: The results depicts that there is a significant change in anxiety levels before and after the Jacobson relaxation intervention. Conclusion: The study's findings contribute to understand the potential benefits of relaxation techniques in managing anxiety among post-COVID geriatric individuals with co-morbid illnesses.
