dc.description.abstract Performance and health issues are common in industry. On-the-job productivity gains related to good design, which could help justify ergonomics intervention, are often not considered. More quantitative data are needed to model the discomfort/productivity relationship for upper limb activity in simulated repetitive assembly type work. Eighteen participants completed an experiment, simulating a repetitive upper limb task with force, posture and grip type recorded as independent variables. Duty cycle time and discomfort were recorded as dependent variables. Participants performed 18 experiment combinations (block designed around force); each treatment lasted 35 min, including breaks. Analysis indicated a significant two-way interaction between posture and grip type. Results from this experiment were used to model the effect of these variables on operator discomfort and performance.Practitioner Summary: Grip type, wrist posture and exertion level can alter the effect of performance and discomfort in repetitive tasks. Careful consideration needs to be given to the choice of grip type in task design and its effects in conjunction with other risk factors such as level of force and awkward posture. en_US
