| Summary: | Work-related musculoskeletal disorders affect a considerable number of workers in the manufacturing sector and is one of the main causes of sick leaves and absenteeism. The use of exoskeletons presents an alternative to reduce musculoskeletal disorders incidence rates and improve performance and human’s well-being when full automation of processes are not feasible and repetitive/demand tasks must be carried out manually. Among the different body regions affected by musculoskeletal disorders, knee injuries present a high prevalence. In this work, we propose the development and evaluation of a passive exoskeleton prototype with the aim of reducing muscle activity during squatting movements. The prototype was fabricated by 3D printing methodology using an environmentally friendly material. Moreover, it fulfilled the requirements of low price, low weight, and possibility of customization. Preliminary results shown a reduction of muscle activity on the leg equipped with the prototype, but further investigations are needed to discard compensation effects on the other leg. |
