Background: Kinesiophobia, the fear of movement due to anticipated pain or re-injury, is increasingly common among aging populations and is linked to chronic conditions. Globally, over 63% of individuals with such conditions experience kinesiophobia, contributing to inactivity, disability, and poor quality of life (QoL). In India, around 52% of older adults have at least one chronic illness, with musculoskeletal disorders being highly prevalent. Aim: To assess the level of kinesiophobia and its impact on pain, disability, and QoL among older adults with chronic circumstances. Methods: A quantitative eloquent study was conducted among 150 older adults (≥60 years) with chronic illnesses at Saveetha Medical College and Hospital, Chennai. Participants were designated using purposive sampling. Validated tools included the Tampa Scale for Kinesiophobia (TSK), Facial Analog Scale (FAS) for pain, Modified Oswestry Disability Index (MODI), and a QoL questionnaire. Descriptive statistics summarized demographics and outcomes, while Karl Pearson’s correlation and Chi-square tests were used for inferential analysis. Results: Among participants, 70% had mild and 30% had strong kinesiophobia. Severe pain (58%) and disability (59. 33%) were commonly reported. QoL was largely rated poor to very poor. Kinesiophobia showed a significant positive correlation with pain (r = 0. 392, p < 0. 001) and disability (r = 0. 336, p < 0. 001), and a negative correlation with QoL (r = –0. 474, p < 0. 001). Educational level and pain duration were significantly associated with kinesiophobia. Conclusion: Kinesiophobia is prevalent in older adults with chronic environments and adversely affects pain, disability, and QoL. Early identification and targeted interventions are essential to improve outcomes.
