Summary: Patients with neurogenic thoracic outlet syndrome often experience pain and weakness in the upper limbs. This study aimed to assess the correlation between isokinetic shoulder strength and hand grip and key pinch strength. The results showed that there was a moderate correlation between grip strength and isokinetic rotators strength, as well as between key pinch strength and isokinetic rotators strength. Hand dynamometers can be useful for assessing overall upper limb weakness, but isokinetic measurement remains the gold standard for precise evaluation.

Summary: Upper extremity dysfunction after stroke can be improved through rehabilitation using a shoulder joint hybrid assistive limb (HAL). This study showed that HAL assisted shoulder movement and improved shoulder muscle strength, voluntary and passive shoulder joint range of motion, as well as overall upper limb function in patients with chronic stroke and upper extremity functional disability. The safety and effectiveness of HAL in motor learning were also demonstrated.

Summary: The dynamic nature of movement and muscle activation highlights the importance of a solid experimental design. In this study, a center-out experiment was conducted with 16 healthy volunteers to evaluate the design using surface electromyography (EMG) and principal component analysis (PCA). The results showed that specific muscles were activated when the direction of the target was opposite to the direction of muscle shortening and when a perturbation was applied in the opposite direction. PCA was also valuable in evaluating participant performance and identifying individual quirks that may impact the study outcomes.

Summary: This study aimed to identify the most effective physical therapy intervention for improving clinical symptoms in patients with post-stroke shoulder-hand syndrome (SHS) through Bayesian network meta-analysis. The results showed that EMG biofeedback combined with rehabilitation training may be the best physical therapy for improving upper limb motor function and relieving pain in patients with post-stroke SHS. However, further analysis and validation by more high-quality RCTs are needed for these conclusions.

Summary: This paper proposes a passive upper limb exoskeleton with tilted and offset shoulder joints, enhanced range of motion, and assistive mechanisms to effectively assist high overhead tasks. Simulations and experiments show that the exoskeleton provides sufficient range of motion at an elevated angle of 165 degrees. The assistive mechanism generates a maximum torque of 9.5 N.m, capable of assisting tasks with a 1-kg tool. Electromyography experiments validate the assistance performance of the exoskeleton, reducing muscle activity significantly.

Summary: This paper introduces a concept called trajectory control, which improves the control of multiple joint upper limb prostheses by coupling the degrees of freedom of the wrist, elbow, and shoulder into coordinated trajectories driven by a single input variable. Experimental results show that trajectory control allows participants to complete tasks faster with similar levels of body compensation compared to sequential and simultaneous control, and it is also found to be more intuitive and result in more natural movements.

Summary: In recent years, companies have been considering the adoption of upper-limb exoskeletons as a solution to reduce health and cost issues caused by work-related shoulder overuse injuries. Previous research mainly evaluated these devices in laboratory settings, but uncertainties remain about generalizing the results to real-world conditions. This study investigated the efficacy, usability, and acceptance of a commercial upper-limb exoskeleton in cleaning job activities, demonstrating significant reductions in shoulder muscle activity and perceived exertion.

Summary: This paper discusses the development trend of using rehabilitation robots for stroke patients with upper limb motor dysfunction, focusing on the establishment of an equivalent mechanism model of the human upper limb. Different configuration combinations were synthesized to select a configuration model with compatibility and reduced moment conduction attenuation, proposing two configurations for the generalized shoulder joint mechanism of the robot. Motion performance analysis and condition reciprocal analysis were conducted to determine that the 5R(a)1P configuration of the shoulder joint has better kinematic performance in the normal upper limb posture of the human body. Finally, a prototype of an upper limb rehabilitation robot with good human-computer compatibility was developed and its moving space was verified.

Summary: Despite EU regulatory standards, many workers suffer injuries as a result of using handheld vibrating tools. This study found that carpenters are more likely to experience neurosensory affection compared to painters, possibly due to vibration exposure. Young carpenters also showed signs of neurosensory affection, indicating inadequate protection for workers in these conditions.

Summary: This study investigated the effects of cleaning spray on the upper airways and physical workload of cleaning workers. The results show that cleaning workers using spray had a higher risk of experiencing symptoms in the eyes, airways, and musculoskeletal pain compared to using other methods. Switching from spray to foam can reduce the concentration of airborne particles and volatile organic compounds, thereby reducing eye and airway symptoms and without increasing the physical workload.

Summary: Approximately 30% of Swedish principals perceive their workability to be excellent. The most frequently encountered managerial demands include role conflicts, resource deficits, and having to deal with colleagues' frustrations. In contrast, supportive managerial colleagues, a supportive private life, and supportive organizational structures are associated with an increased likelihood of reporting excellent workability. Reducing role demands, clarifying areas of responsibility, striving for increased role clarity, and finding ways to separate work and private life should be considered when aiming to improve principals' workability.
