Stress , as measured by Cohens perceived stress questionnaire is not an inclusion criteria , thus participants can participate regardless of their stress level.We will implement an individualized intervention addressing biopsychosocial elements of musculoskeletal pain with the following components ; i ) increasing physical capacity through strength - and motor control training ; ii ) lowering or preventing development of stress through mindfulness practice and learning de-catastrophizing pain management strategies through cognitive training.The primary outcome at 10-week follow-up is the between-group difference in intensity of perceived musculoskeletal pain during the last week ( average value of back , neck , shoulder , elbow and hand ) assessed by questionnaire ( modified visual analogue scale 0-10 ) .
