Objective Surgeons often report musculoskeletal discomfort in relation to their practice, but few understand optimal ergonomic positioning. This study aims to determine which patient position-sitting versus supine-is ergonomically optimal for performing otologic procedures. Study Design Observational study. Setting Outpatient otolaryngology clinic setting in a tertiary care facility. Subjects a...

New technologies and changes in dental care aimed to give the dentist better comfort and better health condition, among them Proprioceptive derivation (Pd) concept was introduce in Thailand. The aim of this study was to investigate the differences in dentist’s working posture when adopting different work concepts: Pd and Conventional concept. The result show differences in dentists’ sitting pos...

background: back and shoulder pain are most common musculoskeletal disorders in students, that the way of sitting or interactions with academic equipment is a major risk factor for these disorders.  the aims of this study is redesign and construct a prototype of painting chair (kharak) by using industrial design and ergonomic methods to reduce musculoskeletal disorders and increase user satisfa...

Background: Although the expansion of innovation in the industry has led to an increase in the fast of works, production and productivity, it has also imposed an increase in the incidence of musculoskeletal disorders. So, the aim of this study was determination the risk level of work posture by REBA and RULA method among workers of assembly line of a cosmetic manufacturing factory. Methods: Th...

We hypothesized that a laparoscopic technique for Roux-en-Y gastric bypass surgery is associated with more musculoskeletal discomfort and ergonomic strain than a robotic technique. This pilot project studied one surgeon while he performed four laparoscopic and four robotic (da Vinci system) Roux-en-Y gastric bypass procedures. We measured musculoskeletal discomfort with body part discomfort sco...

BACKGROUND Dentists are susceptible to Musculoskeletal Disorders (MSDs) due to prolonged static postures. To prevent MSDs, working postures of dental students should be assessed and corrected in early career life. OBJECTIVE This study estimated the risk of developing musculoskeletal disorders in dental students using Rapid Upper Limb Assessment (RULA) tool. METHODS A number of 103 undergrad...

This study aims to compare 3 observational techniques for assessing postural load, namely, OWAS, RULA, and REBA. The comparison was based on the evaluation results generated by the classification techniques using 301 working postures. All postures were sampled from the iron and steel, electronics, automotive, and chemical industries, and a general hospital. While only about 21% of the 301 postu...

The Rapid Upper Limb Assessment (RULA) is an observation-based screening tool that has been used to assess postural risks of children in school settings. Studies using eye-tracking technology suggest that visual search strategies are influenced by experience in the task performed. This study investigated if experience in postural risk assessments contributed to differences in outcome scores on ...

The aim of this study was to formulate the relationship between the total perceived discomfort of the upper limb and perceived discomforts of each degree of freedom (DOF). The biomechanical analysis was performed based on the posture and load classification of the rapid upper limb assessment (RULA), and the joint moments and perceived discomforts of each DOF were calculated. The summary score o...
