Optimising backpack hip belt design: an ergonomic perspective on gait mechanics.
Backpack hip belts help redistribute weight but may limit pelvis and trunk transverse plane rotations. This study explores how hip belt designs influence gait mechanics. Sixteen participants walked under three backpack conditions: a movable hip belt, a spring cross frame and a fixed hip belt, each carrying a 13 kg load. Kinematic data was collected using IMU sensors, and muscle activity with electromyography. The findings reveal that both the spring cross-frame and movable hip belt designs preserve neutral pelvic mobility relative to normal gait. However, only the cross-frame design exhibited a coordination pattern between the pelvis and trunk similar to natural walking, possibly due to its ability to control trunk rotational range of motion (ROM). Additionally, the cross-frame mechanism led to lower erector spinae muscle activation compared to the fixed-frame hip belt. This study emphasises the crucial role of hip belt design in influencing trunk and pelvic movement during walking.
期刊介绍：
Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives.
The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
