1. Efficient strategies for collecting posture data using observation and direct measurement
Abstract : Relationships between occupational physical exposures and risks of contracting musculoskeletal disorders are still not well understood; exposure-response relationships are scarce in the musculoskeletal epidemiology literature, and many epidemiological studies, including intervention studies, fail to reach conclusive results. Insufficient exposure assessment has been pointed out as a possible explanation for this deficiency. READ MORE

2. Nerve conduction and vibrotactile perception thresholds in female computer workers and hand-arm vibration-exposed male manual workers
Abstract : Upper limb pain and disability are common problems, especially among working populations. The overall aim of this thesis was to investigate peripheral nerve function in the upper limb by nerve conduction test and vibration threshold test in working populations including female computer users (n = 82), hand-arm vibration-exposed male manual workers (n = 116), and female workers with chronic diffuse upper limb pain (n = 35).

3. Bias and Precision in Biomechanical Exposure Assessment : Making the Most of our Methods
Abstract : Background: Insufficient exposure assessment is a suggested contributing factor to the current lack of clearly characterised relationships between occupational biomechanical risk factors and musculoskeletal disorders. Minimal attention has been paid to the potential bias of measurement tools from expected true values (i.e. READ MORE

4. Methods to assess physical load at work : With a focus on the neck and upper extremities
Abstract : To prevent work-related musculoskeletal disorders (MSDs), useful, reliable and valid methods for assessing physical workload and risks for MSDs are needed. Ergonomists often assess work by short visual observations without a specific tool. READ MORE

5. Physical load in computerized office work : with special reference to work tasks and equipment
Abstract : The main purpose of the studies presented in this thesis wasto measure and quantify shoulder load in computerised officework. Shoulder load was studied during a whole working day andin different work tasks. Shoulder and arm load during keyboardwork and with different modes of physical computer interactionwas also studied.
