Pain and Distraction According to Sensory Modalities: Current Findings and Future Directions

Abstract

Background: This review discusses the findings in the literature on pain and distraction tasks according to their sensory modality. Distraction tasks have been shown to reduce (experimentally induced) acute pain and chronic pain. This can be influenced by nature and by the sensory modalities used in the distraction tasks. Yet the effect on reducing pain according to the sensory modality of the distraction task has received little attention. Methods: A bibliographic search was performed in different databases. The studies will be systematized according to the sensory modality in which the distraction task was applied.Results: The analyzed studies with auditory distractors showed a reduction of acute pain in adults. However, these are not effective at healthy children and in adults with chronic pain. Visual distractors showed promising results in acute pain in adults and children. Similarly, tactile and mixed distractors decreased acute pain in adults. Conclusion: Distraction tasks by diverse sensory modalities have a positive effect on decreasing the perception of acute pain in adults. Future studies are necessary given the paucity of research on this topic, particularly with tactile distractors (there is only one study). Finally, the most rigorous methodology and the use of ecological contexts are encouraged in future research. &

The Effect of Sleep Quality on Pain in Chilean Individuals with Musculoskeletal Disorders

“…It only has the capacity to capture a particular moment of a condition that often spans a lifetime [ 12 , 50 ]. Finally, it should be emphasized that pain is a complex experience that includes sensory, emotional, cognitive, and social factors [ 51 , 52 , 53 ] that should be addressed in future research on the association of sleep and pain for a richer and more holistic interpretation.…”

Self-management at the core of back pain care: 10 key points for clinicians

“…Living with LBP invariably involves episodes of flare-ups and situations with increased pain. Therefore, patients need a ‘toolbox’ for managing pain and related fears or other emotions which includes tools such as distraction and breathing exercises, 70 mindfulness techniques, 71 , 72 or walking. 72…”

Effect of Adduction During Glenohumeral External Rotation Exercises in the Scapulohumeral Muscles

“…This would add an interesting clinical tool for rehabilitation and / or strengthening programs. Likewise, to individuals with shoulder pain, performing this exercise-that demands great attention resources (ie, concentration)-could distract them from the pain (ie, distraction task; Bascour-Sandoval et al, 2019) and result in performing the exercise with less pain. However, this must be verified by future studies.…”
