Selection of a single design to delight customers may not be always possible due to the anthropometric differences in humans, wherein a hybrid design can benefit. Using adjustability, we demonstrate our approach for developing a novel forklift backrest to accommodate drivers with a wide range of body sizes. Field and laboratory evaluations were conducted to assess and improve the design. Our results indicated that the new design could provide improved comfort for longer durations. This study reveals the possibilities for human factors professionals to consider adjustability in vehicle operator compartment interiors, especially backrests and seating, of similar industrial vehicles.

Implementation of exoskeletons could be one of the solutions to augment human capacity towards reducing the large number of work-related musculoskeletal disorders (WMSDs) in the industry. While many studies highlight the benefits offered by these devices, some show mixed results, which could be due to lack of standardised processes in both development and testing. Further, our observations show that current exoskeletons could be further improved with a goal towards increasing the end-user experience. We have identified the key factors in the design of exoskeletons that could be one of the reasons for the discomfort, misfit and low acceptance of the devices among the workers. Considering the ergonomics principles, we have determined elements of exoskeletons that can be associated with the identified limitations, then provided an overview of some of the modern technologies that are being/could be used, and opportunities for using smart materials to facilitate their design enhancement. Finally, relevant human–machine interaction aspects and the feasibility of applying these technologies in exoskeletons to the industrial environments are discussed. [ABSTRACT FROM AUTHOR]

Stroke survivors often experience reduced movement capabilities due to alterations in their neuromusculoskeletal systems. Modern sensor technologies and motion analyses can facilitate the determination of these changes. Our work aims to assess the potential of using wearable motion sensors to analyze the movement of stroke survivors and identifying the affected functions. We recruited 10 participants (5 stroke survivors, 5 healthy individuals) and conducted a controlled laboratory evaluation for two of the most common daily activities: turning and walking. Among the extracted kinematic parameters, range of trunk and sacrum lateral bending in turning were significantly larger in stroke survivors (p-value<0.02). However, no statistical difference in mean angular velocity and range of motion for trunk/sacrum/shank flexion-extension were obtained in the turning task. Our results also indicated that during walking, while there was no difference in swing time, double support portion of gait among the stroke group was significantly larger (p-value = 0.001). Outcomes of this investigation may help in designing new rehabilitation programs for stroke and other neurological disorders and/or in improving the efficacy of such programs.Clinical Relevance- This study may provide a better insight on the detailed functional differences between stroke survivors and healthy individuals which in turn could be used to develop a more efficient rehabilitation program for stroke community.
