This study was carried out to assess Future Workshop (FW) regarding its usefulness as a participatory ergonomics method, using a descriptive evaluation design analysed by phenomenographical approach. The study was conducted among professional cleaners, health care personnel and miners, with a sample of 105 participating subjects in 8 different FWs. Multiple methods, giving a combination of both qualitative and quantitative data, were used for data collection. Good involvement of participants was observed during workshops. Evaluations immediately after FWs and 3 months later showed a strong relationship with high correlation, indicating that the perception of FW participants was very positive. Interviews revealed conformity between developed problem identification and proposed changes. Participants’ own perceptions of FW’s influence on creativity depict their belief of developed ideas and solutions in order to identify and solve workplace problems. FW is considered to be a useful ergonomics tool, and its qualities are related to structure and practical performance.

Carpet weaving is a high risk occupation for developing musculoskeletal disorders (MSDs). The objectives of the present study, which was carried out in the Iranian hand-woven carpet industry, were determination of the prevalence of MSD symptoms, identification of major factors associated with MSD symptoms and development of guidelines for workstation design. 1,439 randomly selected weavers participated in this study. A questionnaire was used to collect data on MSD symptoms. The results revealed that the prevalence rates for symptoms in different body regions were high as compared to the general Iranian population (for neck, back and large joints, p < .0001). The results of multivariate analyses showed that major ergonomic factors associated with musculoskeletal symptoms were loom type, working posture, daily working time and seat type. Based on the results, some general guidelines for designing weaving workstations were developed. A prototype test showed that the new workstation was acceptable for subject tests and that it improved working posture.
