Article Abstract
Background: Wearable trunk exoskeletons hold immense potential in fields such as healthcare and industry. Previous research has indicated that intention recognition control plays a crucial role in users' daily use of exoskeletons.
Objective: This review aims to discuss the characteristics of intention recognition control schemes for intelligent trunk exoskeletons under different control objectives over the past decade.
Methods: Considering the relatively late development of active trunk exoskeletons, we selected papers published in the last decade (2013 to 2023) from the Web of Science, PubMed, and IEEE Xplore databases. In total, 50 articles were selected and examined based on four control objectives.
Results: In general, we found that researchers focus on trunk exoskeleton devices designed for assistance and motor augmentation, which rely more on body movement signals as a source for intention recognition.
Conclusion: Based on these results, we identify and discuss several promising research directions that may help to attain a widely accepted control methods, thereby advancing further development of trunk exoskeleton technology.

This study evaluated the impacts of five support levels (40, 55, 70, 85, and 100 % actuator strengths) of a passive back-support exoskeleton (BSE) on biomechanical loads associated with commercial crab sorting through musculoskeletal simulation. Whole-body kinematics of 20 male participants performing simulated crab sorting were collected and integrated into a human-BSE interaction simulation framework to predict muscle activity, spinal loads, and contact forces at the human-BSE interfaces. Increasing the BSE support level generally reduced trunk extensor muscle activity (up to 28.

The awkward trunk postures such as static flexion and twisting required of surgeons in the operating room are a major contributing factor to the high prevalence of work-related musculoskeletal disorders amongst surgeons. One intervention that is currently proposed to reduce the strain associated with awkward intraoperative postures are passive exoskeletons worn intraoperatively. In this study, we measured the intraoperative postures, subjective discomfort, and workload as well as the usability associated with two commercially available exoskeletons during three types of vascular surgery and compared the results between a baseline (not using exoskeleton) and two different trunk exoskeletons (Laevo and HeroWear).

This paper presents a novel cable-driven exosuit intended for head-neck support and movement assistance. Mobility limitations in the head-neck, such as dropped head syndrome, can result from various neurological disorders. Current solutions, ranging from static neck collars to rigid-link robotic neck exoskeletons, are unsatisfactory.

Biomechanical modeling of the human trunk is crucial for understanding spinal mechanics and its role in ergonomics and clinical interventions. Traditional models have been limited by only considering the passive structures of the spine in finite element (FE) models or incorporating active muscular components in multi-body musculoskeletal (MS) models with an oversimplified spine. To address those limitations, we developed a subject-specific coupled FE-MS model of the trunk and explored its applications in ergonomics and surgical interventions.

IEEE Int Conf Rehabil Robot

Mediolateral balance during walking is a critical aspect of functional mobility, particularly in populations with neuromuscular disorders. Step width is one of the key gait parameters influencing balance, and mediolateral hip exoskeletons have emerged as potential tools to modulate step width for improved stability. This study investigated the effects of exoskeleton-controlled step width on mediolateral gait balance represented by various gait balance metrics, including trunk sway, margin of stability (MoS), net external moment, and step width variability, in healthy individuals.
