Ergonomic Risk Assessment of Dental Students—RULA Applied to Objective Kinematic Data
2021
Musculoskeletal disorder (MSD) is already prevalent in dental students despite their young age and the short duration of dental practice. The current findings state that the causes of MSD are related to posture during dental work. This study aims to investigate the ergonomic risk of dental students. In order to analyze the ergonomic risk of dental students, 3D motion analyses were performed with inertial sensors during the performance of standardized dental activities. For this purpose, 15 dental students and 15 dental assistant trainees (all right-handed) were measured in a team. Data were analyzed using the Rapid Upper Limb Assessment (RULA), which was modified to evaluate objective data.…
Ergonomic Comparison of Four Dental Workplace Concepts Using Inertial Motion Capture for Dentists and Dental Assistants
2021
When the inventory is arranged in a dental practice, a distinction can be made between four different dental workplace concepts (DWCs). Since the prevalence of musculoskeletal diseases in dental professionals is very high, preventive solution need to be investigated. As the conventionally used DWCs have, to date, never been studied in terms of their ergonomics, this study aims to investigate the ergonomic risk when working at the four different DWCs. In total, 75 dentists (37 m/38 f) and 75 dental assistants (16 m/59 f) volunteered to take part in this study. Standardized cooperative working procedures were carried out in a laboratory setting and kinematic data were recorded using an inerti…
Combining Ergonomic Risk Assessment (RULA) with Inertial Motion Capture Technology in Dentistry—Using the Benefits from Two Worlds
2021
Traditional ergonomic risk assessment tools such as the Rapid Upper Limb Assessment (RULA) are often not sensitive enough to evaluate well-optimized work routines. An implementation of kinematic data captured by inertial sensors is applied to compare two work routines in dentistry. The surgical dental treatment was performed in two different conditions, which were recorded by means of inertial sensors (Xsens MVN Link). For this purpose, 15 (12 males/3 females) oral and maxillofacial surgeons took part in the study. Data were post processed with costume written MATLAB® routines, including a full implementation of RULA (slightly adjusted to dentistry). For an in-depth comparison, five newly i…
Darba vides riska faktoru un stresa ietekme uz Liepājas aptiekā strādājošo farmaceitu darba spējām
2019
Maģistra darbā ir pētīti darba vides riska faktori un stresa ietekme uz farmaceitiem, un to saistība ar nodarbināto darbspējām. Darbs sastāv no trīs daļām. Pirmajā daļā ir apkopota un analizēta literatūra par farmaceitu profesiju, kā arī ergonomiskiem un psihosociāliem riskiem. Otrajā daļā aprakstītas pētījumā lietotās metodes, bet trešajā daļā veikta iegūto rezultātu apkopošana un analīze. Literatūras analīze liecina, ka farmaceiti, kuri strādā aptiekā, pakļauti daudzveidīgiem darba vides risku faktoriem (fiziskiem, ergonomiskiem, psihosociāliem). Maģistra darbā, tika izmantotas Eiropā populāras darba vides risku un stresa līmeņu, novērtēšanas metodes. Iegūtie rezultāti uzrāda, ka farmacei…
Psihoemocionālie un ergonomiskie darba vides riski, preventīvie pasākumi veselības aprūpē nodarbinātajiem
2015
Psihoemocionālie un ergonomiskie darba vides riski, preventīvie pasākumi veselības aprūpē nodarbinātajiem. Maģistra darbs, 69 lappuses, 11 attēli, 22 tabulas, 42 literatūras avoti, 3 pielikumi. Latviešu valodā. Darbs sastāv no 3 daļām. Pirmajā daļā ir veikta literatūras analīze. Tā norāda, ka veselības aprūpē nodarbinātie savā ikdienas darbā pamatā pakļauti psihoemocionālajiem un ergonomiskajiem riska faktoriem. Otrajā daļā ir aprakstītas pētījumā lietotās metodes. Trešajā daļā veikta rezultātu analīze un to iztirzājums. Iegūtie pētījuma rezultāti ļauj secināt, ka veselības aprūpē nodarbinātie, veicot smagumu celšanu un pārvietošanu, ir pakļauti palielinātai fiziskajai slodzei, darba pienāk…
Ergonomic Risks in the Printing Company and Workers’ Wellbeing
2014
The aim of the study was to analyze the ergonomic risks in the printing company and to study the impact of ergonomics risks on employees’ wellbeing. The study involved 67 company workers aged 18 to 67 years. In the study, physical load evaluation methods and questionnaire on welfare and psychoemotional risks at work, adopted by Swedish Environmental Research Institute, were used. It was proved that production workers were subjected to increased physical workload. At work they are exposed to physical pressure on hands, shoulders and back. The workload is more affected by the increase in work tension due to limited time of order execution. It was concluded that ergonomic risks partly affect e…
