Opis:: This study reports on the development and validation of a new computer model for simulating human postures at work, and assessing the reaction forces and bending moments in 43 human articulation joints. The proposed model estimates the intradiscal pressure in the vertebral column in response to external loading forces encountered during human interactions with work objects or processes. The model was implemented in a selfcontained interactive software package. The simulation results compare favorably with the reported experimental data, and provide reasonable confidence in the quality of the model. Its characteristics and its applications in evaluating physical task performance are also discussed.

Opis:: This study attempted to identify a direct relationship between the design characteristics of a manually-assembled product, exposure to work-related ergonomic risk factors, and improvement in product quality. The study considered (a) Accessibility (ease of approach) and Guidance (ease of alignment and positioning) as Design Variables, (b) Shoulder Abduction, Trunk Lateral Flexion, Rate-Normalized Percentage of Maximal Voluntary Contraction (%MVC) of the Wrist Flexors, Wrist Extensors, and Deltoids, and Frequency of Attachment as Ergonomics Variables, and (c) Percentage of Attachment Too Loose, Too Tight, and Misaligned as Quality Variables. Postural data, surface EMG data, and quality data were collected from 10 participants performing four 10-min repetitive manual assembly tasks with plastic threaded nuts, bolts, flat parts, and open-box parts. Unobstructed accessibility of manually-assembled parts was associated with decreased exposure to awkward trunk posture, decreased activity of the wrist flexors and extensors, increased frequency of repetitive motion, and a decrease in the tendency to attach parts too loosely. Accessibility had no effect on misalignment defects as measured. Part guidance decreased the number of parts attached too tightly and aided in increasing the rate of assembly of parts when there was unobstructed access to parts
