Introduction
My research interest concerns Ergonomics/Human Factors, aiming to optimize human health and performance in the workplace.
My research concerns optimization, design and evaluations of methods and tools to assess biomechanical exposures, to make those usable for OSH practitioners and companies, and apply them for interventions to reduce or optimize biomechanical exposures.
I am member of the Editorial Board of International Journal of Industrial Ergonomics.

The gap was investigated using a rapid review comprising a literature search using two databases and 11 reviews/overviews t...
Sensor type (accelerometers only versus inertial measurement units, IMUs) and angular velocity computational method (inclination versus generalized velocity) have been shown to affect the measurements of arm and trunk movements. This study developed models for conversions between accelerometer and IMU measurements of arm and trunk inclination and b...
Background
Musculoskeletal disorders (MSDs) are common among surgeons, and its prevalence varies among surgical modalities. There are conflicting results concerning the correlation between adverse work exposures and MSD prevalence in different surgical modalities. The progress of rationalization in health care may lead to job intensification for su...
Introduction: Heavy and repetitive manual handling are considered risk factors for muskuloskeletal disorders. To reduce adverse health effects, vibrotactile feedback training may be used as a complementary strategy. The main aim of this study was to evaluate the short- and medium-term effect of concurrent posture-correction vibrotactile feedback tr...
Recent demographic developments in Europe have increased the demand for home care. Working in other people’s home environment is challenging. Home care personnel’s musculoskeletal disorders are common, and care personnel overall often have sleep disturbances. In this study, associations between occupational physical and psychosocial factors and pos...
Accelerometer-based inclinometers have dominated kinematic measurements in previous field studies, while the use of inertial measurement units that additionally include gyroscopes is rapidly increasing. Recent laboratory studies suggest that these two sensor types and the two commonly used angular velocity computational methods may produce substant...
Distance laboratory training in ergonomics with a flipped-classroom approach and smartphone applications as a tool was designed, implemented, and evaluated at two Swedish universities. Most students (10/13) were satisfied with the laboratory training. In this small-scale study, sufficient preparation time, tailored instructions and timely support d...
Vibrotactile feedback training may be one possible method for interventions that target at learning better work techniques and improving postures in manual handling. This study aimed to evaluate the short term effect of real-time vibrotactile feedback on postural exposure using a smart workwear system for work postures intervention in simulated ind...
Work-related musculoskeletal disorders are a major concern globally affecting societies, companies, and individuals. To address this, a new sensor-based system is presented: the Smart Workwear System, aimed at facilitating preventive measures by supporting risk assessments, work design, and work technique training. The system has a module-based pla...

The package consists of the RAMP tool (Risk Assessment and Management tool for manual handling Proactively), the RAMP website, and free, globally available online, training courses (MOOCs). An Action modu...
Hemtjänstpersonal drabbas ofta av psykisk ohälsa och belastningsskador. Projektet kartlade hemtjänstpersonalens arbetsbelastning, undersökte sambanden mellan belastning och hälsa samt försökte finna hälsoriskerna. Projektgruppen tog också fram riktlinjer för hur hemtjänsten kan organiseras för bättre arbetshälsa.

Musculoskeletal disorders (MSDs) are major causes for disability, reduced work ability and early exit from the labour market. The aetiology is understood to be multifactorial and MSDs are known to have a recurrent course characterized by development, recovery, reoccurrence and chronic states. Studies classifying participants as suffering from e.g....

Background: We have developed an ambulatory wearable system for assisting risk
assessment and automated training to reduce adverse postural exposures. This study evaluated the effects of direct vibrotactile feedback using the sy...
Feedback training of postural behaviour is one possible strategy of reducing the risk for work-related musculoskeletal disorders. Automated self-training could possibly have an impact on such disorders. The aim was to experimentally test the short-term effects of two low cost self-training approaches, targeting a reduction in the time of upper arm...
