Prostate cancer (PCa) survivors often experience post-treatment challenges that impact their well-being and mental health. The Prostate Cancer Patient Empowerment Program (PC-PEP) aims to address these issues through a comprehensive intervention, involving daily meditation/breathing exercises, physical activity, pelvic floor exercises, emotional connection strategies, and peer support. This study presents a secondary analysis of a Phase 2 feasibility study that evaluated the effects of a 28-day PC-PEP intervention on stress reduction. Thirty patients with PCa from the Maritimes, Canada, underwent pre- and post-intervention assessments to measure brainwave activity (delta, theta, alpha, beta, and gamma) using the Muse™ headband, and heart rate variability (HRV) using the HeartMath Inner Balance™ as indicators of stress reduction. A statistically significant Time × Sensor Scalp Assessment Time interaction emerged for all brain waves. Amplitudes were generally higher during the first half of the meditation assessment time but became comparable afterward. A statistically significant Time × Sensor Scalp Location × Sensor Scalp Assessment Time interaction also emerged for alpha waves, indicating higher prefrontal lobe amplitudes than temporal lobe amplitudes from pre- to post-assessment. There were no statistically significant differences in HRV metrics from pre- to post-intervention, except for a marginally significant achievement score, indicating increased HRV coherence post-intervention. The findings suggest that the stress reduction component of PC-PEP successfully improved outcomes related to decreased stress. These results have implications for the development of future iterations of PC-PEP interventions, aiming to optimize participant benefits.
前列腺癌(PCa)幸存者常常经历治疗后的挑战,这会影响他们的幸福感和心理健康。前列腺癌患者赋权计划(PC-PEP)旨在通过综合干预来解决这些问题,包括每日冥想/呼吸练习、身体活动、骨盆底练习、情感联系策略和同伴支持。本研究对一项评估 28 天 PC-PEP 干预对减轻压力效果的 2 期可行性研究进行了二次分析。加拿大新斯科舍省的 30 名前列腺癌患者接受了干预前后的评估,使用 Muse™头带测量脑电波活动(δ、θ、α、β和γ),并使用 HeartMath Inner Balance™测量心率变异性(HRV),作为减轻压力的指标。所有脑电波均出现了统计学上显著的时间×传感器头皮评估时间的相互作用。振幅在冥想评估时间的前半段通常较高,但之后变得相当。α波也出现了统计学上显著的时间×传感器头皮位置×传感器头皮评估时间的相互作用,表明从评估前到评估后,前额叶的振幅高于颞叶。HRV 指标在干预前后没有统计学上的显著差异,除了成就得分略有显著,表明干预后 HRV 一致性增加。这些发现表明,PC-PEP 的减轻压力部分成功改善了与压力降低相关的结果。这些结果对未来 PC-PEP 干预措施的发展具有重要意义,旨在优化参与者的受益。
