In recent years, Romania’s stomatology private practice sector has seen substantial growth, with many dentists fully committing to building and expanding their own practices, often funded by their personal income. This study aimed to explore how various postures affect the muscle groups of dentists (380), particularly focusing on identifying positions that may jeopardize their musculoskeletal health. A group of dentists effectively participated in this study (10), adhering to their regular work routines while wearing wearable sensors on their backs to monitor posture and activity. The data gathered from these sensors were analyzed using the RULA (rapid upper-limb assessment) and REBA (rapid entire-body assessment) tools. The findings indicated that the head and shoulder movements during dental procedures involved considerable and repetitive angular shifts, which could strain the neck and back muscles and heighten the risk of musculoskeletal problems. Additionally, the standing postures adopted by the dentists were associated with an increased risk of postural issues and greater overall fatigue. Extended periods of trunk and head tilting were also identified as contributing factors to posture-related challenges.

Low vision is a major factor limiting mobility and increasing the risk of falls globally, with a significant impact on quality of life. The article presents the analysis of the effects of simulated visual dysfunctions—cataract and glaucoma—on the biomechanical parameters of gait and evaluates the effectiveness of a portable device based on ultrasonic sensors, called the Tridirectional Device. A sample of 25 clinically healthy subjects was evaluated in five experimental conditions, using a plantar pressure distribution analysis system (RSScan), the Tinetti scale and the center of pressure trajectory analysis. The results highlight changes in gait parameters under the conditions of use of the device, suggesting its potential as an accessible and non-invasive solution for supporting people with visual impairments.
