The specific aims of this project were to study the effectiveness and the efficacy of ergonomic interventions for the reduction of musculoskeletal injuries/illnesses in the commercial crab fishing industry and, more generally, to explore some of the unique ergonomic and/or biomechanical challenges faced by workers in this industry. This research effort can be broken down into five research projects that were completed during the period of this grant. The aim of Project # I was to identify those jobs and work tasks that were most problematic from the perspective of musculoskeletal injury/illness. This was accomplished through surveys and interviews of commercial fishermen. The result of this structured analysis was a list of jobs/work tasks prioritized in terms of numbers and severity of musculoskeletal injury/ illness risk. The aim of Project #2 was to identify the specific physical risk factors posed by these work tasks jobs. This process involved video analysis of these work activities wherein the physical stressors were documented. The result of this video task analysis process was a detailed description of the physical exposures (forces, postures, repetition rates, exposure to vibration, etc.). The aim of Project #3 was to design, engineer and prototype engineering and work practice controls with the expressed goal of eliminating or reducing exposure to the identified risk factors. This process was often an iterative process that involved both lab testing (see Project #4 below) as well as feedback from fishermen (see Project #5 below). The aim of Project #4 was to perform a formal laboratory analysis of the prototypes developed through Project #3. Project #4 involved the use of bioinstrumentation (electromyography, electrogoniometry, magnetic-based motion analysis systems) to precisely quantify the impact of the prototyped interventions on the risk factors that the prototypes were designed to address. The result of this structured, formal, biomechanical analysis of these prototypes was quantitative information with regard to the prototype that I) illustrated that the prototype was ready for a formal field assessment (Project #5) or 2) the prototype could/should be re-engineered and re-prototyped to arrive at a design that is able to further reduce exposure to the identified risk factors. The aim of Project #5 was to perform a field analysis of the prototypes developed through Project #3 and assessed in Project #4. This process involved a subjective assessment of the design by commercial crab fishermen.
