First responders participate in an eight-week, synchronous virtual mindfulness intervention, during work hours, with access to companion smartphone app to reinforce virtually presented content and support individual mindfulness practices.

Mindfulness in Motion (MIM) is an eight-week, evidence-based workplace intervention designed to provide participants with practical strategies to reduce stress and burnout, and improve resilience.

The Modified Nordic Musculoskeletal Questionnaire is a standardized 14-item tool assessing musculoskeletal symptoms, over the past 12 months and past 7 days, across multiple body regions. Q. 1 asks about musculoskeletal pain in 9 anatomical areas include the neck, shoulders, upper back, elbows, lower back, wrists/hands, hips/thighs, knees, and ankles/feet--yes/no are responses. Q. 2 asks frequency of musculoskeletal issues in the 9 anatomical areas over the past 30 days with Q. 3 asking about length of time related to the musculoskeletal pain and Q. 4 about intensity of the pain that was indicated. With yes/no responses, Q. 5 & 6 asks if pain has interfered with usual activities; question 7 asks if a healthcare provider was seen. Q. 9, 10, 11 asks if work activities have been disrupted and if a formal diagnosis was determined. Q. 12, 13, and 14 asks about related symptoms. The tool uses a structured, forced-choice format supported by a body map. There is no minimum or maximum score.
