Chronic low back pain (CLBP) is a critical public health issue and affects a significant number of people physically, emotionally, and financially. There is evidence that pain may affect one’s perception of time, but more work is needed to understand how different types of pain (acute, chronic) impact temporal perception. This study aimed to examine how acute experimental pain and CLBP, together and separately, impact the perception of time. A sample of 77 participants, 10 with CLBP and 67 healthy pain-free controls, completed two temporal perception tasks (Bisection and Threshold) twice, once with induced acute pressure pain and once without pain. The effects of acute pain and CLBP on temporal perception were examined using repeated measures ANOVAs. Results showed that the presence of either acute or chronic pain was related to overestimating time during shorter stimuli presentations and underestimating time during longer stimuli presentations. Further, subjects with chronic pain generally required a longer time difference to accurately distinguish between stimuli of differing lengths. This study demonstrates that both acute and chronic pain affect temporal perception, though the combination of acute and chronic pain does not confer additive adverse effects. The results of this study broaden our understanding of the impact of different types of pain on a person’s perception of time. / 2025-02-03T00:00:00Z
