“…In order to obtain more detailed and objective information, Vignais et al [ 16 , 17 ] suggested using the scoring system on inertial motion capture (IMC) data, which can be used in real work environments. IMC systems, such as MVN Link by Xsens (Enschede, The Netherlands), have been developed further recently and are now considered as accurate and reliable, especially for the investigation of slower movements [ 18 , 19 ], such as those found during dental treatment procedures [ 20 ].…”

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 inertial motion capture system. The data were applied to an automated version of the Rapid Upper Limb Assessment (RULA). Comparisons between the DWCs and between the dentists and dental assistants were calculated. In all four DWCs, both dentists and dental assistants spent 95–97% of their working time in the worst possible RULA score. In the trunk, DWCs 1 and 2 were slightly favorable for both dentists and dental assistants, while for the neck, DWC 4 showed a lower risk score for dentists. The ergonomic risk was extremely high in all four DWCs, while only slight advantages for distinct body parts were found. The working posture seemed to be determined by the task itself rather than by the different inventory arrangements.

“…In recent years, the focus of research in this field has concentrated on ergonomic activities and processes within individual medical specialties such as surgery [21,22] or gastroenterology [23]. In particular, during new surgical procedures [24] and new treatment techniques [25][26][27][28], musculoskeletal imbalances have been reported: 66-94% of surgeons report work-related MSD in open surgery [11,21,24,[29][30][31], 73-100% in conventional laparoscopy [32,33], 54-87% in vaginal surgery and 23-80% in robotic surgery [25,27,28,[34][35][36].…”

Background The aim of this pilot study was to analyze postures during the work of neurologists with respect to their occupational activities. Methods A total data material of 64.8 h (3885.74 min) of nine (three m/six f) neurologists (assistant physicians) was collected. Kinematic data were collected using the CUELA system (electro-goniometry). In addition, the occupational tasks performed on-site were subject to a detailed objective activity analysis. All activities were assigned to the categories “Office activities” (I), “Measures on patients” (II) and “Other activities” (III). The angle values of each body region (evaluation parameters) were evaluated according to ergonomic ISO standards. Results Only 3.4% of the working hours were spent with (II), while 50.8% of time was spent with (I) and 45.8% with (III). All tasks of category (II) revealed an increased ergonomic risk to the head, neck, trunk and back areas. During category (I) especially neck and back movements in the sagittal plane showed higher ergonomic risk levels. Conclusion Despite frequently performed awkward body positions in (II), the ergonomic risk is considered as rather low, since the percentage time share totaled only 3.4%. As a result, “Office activities” have been detected as high predictor to cause stress load on the musculoskeletal system in the daily work of neurologists.

“…However, data on static postures are lacking. In previous studies the Rapid Upper Limb Assessment (RULA) [15,16] was used to measure static postures [15]. Static postures can also be analyzed by means of kinematic analysis, for which the computer-assisted acquisition and long-term analysis of musculoskeletal loads system (CUELA) can be used [2,13,[17][18][19].…”

Background The aim of this pilot study was to analyze the work of neurologists regarding static posture (> 4 s) and to identify awkward postures. Methods A total of 9 neurologists (assistant physicians; 3 male, 6 female) participated in this study. Kinematic data were collected using the computer-assisted acquisition and long-term analysis of musculoskeletal loads (CUELA; IFA, Sankt Augustin, Germany) system. Daily work (“office work,” “measures on patients,” and “other activities”) was analyzed with a computer-based task analysis. Results During ”measures on patients,” more than 80% of the total percentage of non-neutral posture was assumed with a flexed position of the head and entire back, both during “blood collection” (4.7% of the time) and while “placing intravenous catheters” (8.3% of the time). In contrast, long static postures (> 30 s) in the head and neck area, including the thoracic spine, were adopted during “office work.” Despite the increased total percentage of non-neutral attitudes during measures on patients, the time share of 3.4% of the total working time is so small that the risk for developing musculoskeletal disorders (MSD) is negligible. In contrast, office work, which comprises 50.8% of the total working time and longer static postures, has a potential risk for the development of MSD. Conclusion The present study is the first kinematic pilot analysis in the field of in-patient neurological assistants. Non-neutral as well as static postures in everyday work could be identified. Potential MSD can be reduced by optimizing the working height and by taking regular breaks to loosen the musculoskeletal system.
