Chronic work-related stress is quite prevalent in the working population and is in some cases accompanied by long-term sick leave. These stress complaints highly impact employees and are costly due to lost productivity and medical expenses. A new treatment platform with light therapy plus Pulsed Electro Magnetic Fields (PEMF) in combination with coaching was used to assess whether more positive effects on return to work, stress, work-related fatigue, and quality of life could be induced compared to coaching alone.
A placebo-controlled trial was executed after inclusion of 96 workers, aged 18-65 with work-related chronic stress complaints and who were on sick leave (either part-time or full-time). Participants were divided into three arms at random. Group 1 (n = 28) received the treatment and coaching (Intervention group), group 2 (n = 28) received the treatment with the device turned off and coaching (Placebo group) and group 3 (n = 28) received coaching only (Control group). The data were collected at baseline, and after 6, 12 and 24 weeks. The primary outcome was % return to work, and secondary outcomes were work-related fatigue (emotional exhaustion and need for recovery after work), stress (distress and hair cortisol), and quality of life (SF-36 dimensions: vitality, emotional role limitation, and social functioning).
Eighty-four workers completed all measurements, 28 in each group. All groups improved significantly over time in the level of return to work, as well as on all secondary outcomes. No statistical differences between the three groups were found either on the primary outcome or on any of the secondary outcomes.
Light therapy with Pulsed Electro Magnetic Fields PEMF therapy has no additional effect on return to work, stress, fatigue, and quality of live compared to coaching alone.

慢性工作相关压力在工作人群中相当普遍，在某些情况下还伴随着长期病假。这些压力投诉对员工有很大影响，并且由于生产力损失和医疗费用而成本高昂。一个新的治疗平台，将光疗法与脉冲电磁场（PEMF）相结合并辅以指导，用于评估与单独指导相比，是否能对重返工作、压力、工作相关疲劳和生活质量产生更积极的影响。
在纳入96名年龄在18 - 65岁、患有工作相关慢性压力投诉且正在休病假（兼职或全职）的工人后，进行了一项安慰剂对照试验。参与者被随机分为三组。第1组（n = 28）接受治疗和指导（干预组），第2组（n = 28）接受设备关闭状态下的治疗和指导（安慰剂组），第3组（n = 28）仅接受指导（对照组）。在基线以及6周、12周和24周后收集数据。主要结局是重返工作的百分比，次要结局是工作相关疲劳（情绪耗竭和下班后恢复需求）、压力（苦恼和头发皮质醇）以及生活质量（SF - 36维度：活力、情感角色限制和社会功能）。
84名工人完成了所有测量，每组28人。随着时间的推移，所有组在重返工作水平以及所有次要结局方面均有显著改善。在主要结局或任何次要结局上，三组之间均未发现统计学差异。
与单独指导相比，脉冲电磁场光疗法对重返工作、压力、疲劳和生活质量没有额外影响。
