The participant applied a 7 kg weighted blanket in a folded configuration to concentrate pressure on specific anatomical regions (shoulders, lumbar spine, hips) while seated in a supportive chair. Daily sessions (20\u201340 minutes) were performed under low-stimulation conditions. Outcome measures included Numeric Rating Scale (NRS) pain scores, subjective relaxation indices, and heart rate variability (HRV), specifically RMSSD.<\/p>\n\n\n\n<p><strong>Results:<\/strong> Mean pain scores decreased from 6\/10 at baseline to 2\/10 at week four. HRV (RMSSD) increased from 28 ms to 38 ms (+35%), indicating enhanced parasympathetic activity. The intervention was well tolerated with no adverse events reported.<\/p>\n\n\n\n<p><strong>Conclusion:<\/strong> Targeted deep pressure application via weighted blankets may represent a low-cost, non-invasive modality for managing chronic pain and autonomic dysregulation.

Introduction<\/h2>\n\n\n\n<p>Chronic musculoskeletal pain is frequently associated with autonomic dysregulation, characterized by elevated sympathetic tone and reduced parasympathetic activity [1,2]. Non-pharmacological interventions that restore autonomic balance are of increasing clinical interest [3].<\/p>\n\n\n\n<p>Weighted blankets have been widely studied in the context of anxiety, insomnia, and sensory processing disorders [4,5,6], with emerging evidence supporting their role in inducing parasympathetic dominance through deep pressure stimulation (DPS) [7,8]. DPS is hypothesized to activate cutaneous and fascial mechanoreceptors, influencing vagal pathways and neuroendocrine responses [9,10].<\/p>\n\n\n\n<p>However, current applications are predominantly <strong>diffuse (whole-body)<\/strong> rather than targeted, potentially limiting their effectiveness for localized pain conditions [11].<\/p>\n\n\n\n<p>This study introduces <strong>Targeted Weighted Blanket Therapy (TWBT)<\/strong> , a protocol designed to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Concentrate pressure on specific pain regions<\/li>\n\n\n\n<li>Enhance localized neuromuscular relaxation<\/li>\n\n\n\n<li>Amplify systemic parasympathetic response<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Parameter<\/th><th>Full-Body Application<\/th><th>Targeted Application (TWBT)<\/th><\/tr><\/thead><tbody><tr><td>Pressure density<\/td><td>~10\u201315 kg\/m\u00b2<\/td><td>~30\u201340 kg\/m\u00b2<\/td><\/tr><tr><td>Primary effect<\/td><td>Generalized relaxation<\/td><td>Localized pain modulation + autonomic regulation<\/td><\/tr><tr><td>Position<\/td><td>Supine<\/td><td>Seated (or supine)<\/td><\/tr><tr><td>Application time<\/td><td>20\u201360 min<\/td><td>20\u201340 min<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2.
