Sensory stimulation has shown the capacity to modulate pain mechanisms. Yet, the optimal methods of sensory stimulation remain uncertain. Afforestation activities stand out as a potential stimulation method, as they allow individuals to interact with multisensory stimuli produced in green environments. Exposure to natural multisensory stimuli has been shown to induce neurobiological activations in pain-related brain areas in healthy populations. However, the possible impact of the natural multisensory stimuli on the pain mechanisms themselves is yet to be explored. This study aimed to investigate the potential effects of sensory stimulation experienced during participation in an afforestation program on thermal and mechanical pain mechanisms. A single-group, pretest-posttest clinical trial was used. Forty-seven healthy adults performed an afforestation activity for 90 minutes. Measurements included cold pain detection and tolerance thresholds via the Cold Pressor Test, wind-up and mechanical pain sensitivity through a pinprick stimulator, and pressure pain detection and tolerance thresholds utilizing pressure algometry. For both thermal and mechanical pain thresholds, pain intensity was assessed using the 101-point Numeric Rating Scale. The results showed significant reductions in the cold pain intensity at the moment of detection (p = .046), mechanical pain sensitivity (p ≤ .014), and increases in the thresholds of pressure pain detection (p = .005) and tolerance (p ≤ .046). Therefore, the interaction with natural multisensory stimuli could be a possible therapeutic strategy to positively modulate mechanical pain sensitivity and pressure pain thresholds.

感觉刺激已显示出调节疼痛机制的能力。然而，感官刺激的最佳方法仍然不确定。造林活动作为一种潜在的刺激方法脱颖而出，因为它们允许个体与绿色环境中产生的多感官刺激互动。研究表明，接触自然的多感觉刺激可以诱导健康人群中与疼痛相关的大脑区域的神经生物学激活。然而，自然多感觉刺激对疼痛机制本身可能产生的影响仍有待探索。本研究旨在调查参与造林计划期间经历的感觉刺激对热和机械疼痛机制的潜在影响。采用单组、前测-后测临床试验。47名健康成年人进行了90分钟的造林活动。测量包括通过冷压测试的冷痛检测和耐受阈值、通过针刺刺激器的结束和机械疼痛敏感性，以及利用压力测痛法的压痛检测和耐受阈值。对于热痛和机械痛阈值，使用 101 点数字评定量表评估疼痛强度。结果显示，检测时的冷痛强度 ( p  = .046)、机械疼痛敏感性 ( p  ≤ .014) 显着降低，压痛检测阈值 ( p = .005) 和耐受性 ( p = .005) 显着增加。 p  ≤ .046)。因此，与自然多感觉刺激的相互作用可能是积极调节机械疼痛敏感性和压力痛阈值的一种可能的治疗策略。
