Wstęp. Praca lekarza stomatologa często wymaga długotrwałego utrzymywania wymuszonej, nieergonomicznej pozycji ciała podczas pracy. Powoduje to, że przez wiele godzin kręgosłup stale narażony jest na przeciążenia. To z kolei może objawiać się bólami kręgosłupa. Od pewnego czasu stomatolodzy mają dwie możliwości sposobu pracy. Pracują z prawego boku pacjenta, co wymaga pochylenia się w przód i w prawo lub mają możliwość pracy zza głowy pacjenta wykorzystując specjalnie do tego przystosowane krzesło wymuszające prawidłowe ustawienie kręgosłupa. Materiał i metody. Badania, które zostały przeprowadzone, dotyczyły oceny występowania bólów kręgosłupa lędźwiowego u lekarzy stomatologów z podziałem na dwie grupy w zależności od przyjmowanej pozycji podczas pracy. Badaniami objęto 63 lekarzy. W celu oceny wykorzystano kilka prostych testów oraz ankietę utworzoną na potrzebę badania. Wyniki. W grupie lekarzy pracujących z boku pacjenta 18 badanych (54,5%) wskazywało na szósty stopień bólu, 11 badanych (33,3%) na siódmy oraz czworo badanych (12,1%) na piąty stopień bólu w skali VAS. U stomatologów z grupy pracujących w pozycji zza głowy pacjenta, skala bólu nie przekroczyła trzech. Wnioski. Pozycja podczas pracy lekarza stomatologa ma istotny wpływ na powstawanie dolegliwości bólowych kręgosłupa lędźwiowego. Pozycja lekarza pracującego zza głowy pacjenta jest bardziej ergonomiczna niż z boku pacjenta. Lekarze pracujący z boku pacjenta częściej zgłaszają dolegliwości bólowe kręgosłupa lędźwiowego.

Introduction. The work of a dental surgeon often entails remaining in a forced and non-ergonomic body posture for a prolonged time. Consequently, the spine is exposed to overstraining for many hours. This in turn may manifest in spine pain disorders. For some time now, dentists can choose between two working methods. They proceed at the patient’s right-hand side, which requires them to lean forward and rightward, or they may work from behind the patient’s head using a specially adjusted chair that enforces a proper position of the lumbar spine. Material and methods. The research was carried out to assess dentists’ lumbar spine pains. The subjects were divided into two groups depending on the posture they adopted while working. The research included 63 dentists. To analyse the results, a few simple tests and a questionnaire were carried out. Results. Among the dentists proceed at the patient’s right- hand side, 18 of them (54,5%) indicated on the sixth level of pain, 11 patients (33,3%) the seventh level of pain and four (12,1%) dentists suffered from pain at fifth level of the pain scale (0-10). In the group of dentists working in the position from behind the patient’s head pain scale did not exceed third level. Conclusion: dentists’ working posture has a significant impact on the formation of the lumbar spine disorders. Position of the dentists working from behind the patient’s head is more ergonomic than position while working on the patient’s one side. Dentists working on patient’s one side more often report the pain in a low back spine section.

Objectives: The most frequent manner of attending childbirth imposes on midwives assuming poor body position affecting the musculoskeletal system. Long professional experience does not mitigate the negative effects. The adopted movement habit, as well as the type, number and frequency of actions influence the body posture. The aim of the study was to identify ergonomic threats of basic occupational midwives activities and how particular spinal segments arrangements while attending childbirth using the same technique in senior midwives differ from those of junior ones. It was also checked whether pain influences the working position assumed by midwives. Materials and Methods: Examinations were conducted in 95 midwives aged 21–50 (X = 29.25±9.34): 51 graduates of BSc midwifery who worked 680 h in delivery rooms during obligatory practical classes and apprenticeship and 44 senior midwives with professional experience of 7–27 years (X = 14.84±5.98). The study was threefold. The spinal alignment while performing work activities associated with attending childbirth was assessed using the OWAS system and the SonoSens Monitor, the center of gravity projection on basal plane – using the AccuGait AMTI stabilometric platform. The measurements were taken during a simulation of attending childbirth (on examination model). A survey was conducted aimed at identifying spinal pain. Results: Midwives’ working postures require unnatural body alignments. Postural instability in the working position and no maximal usage of basal plane were observed. The work overload may afflict the musculoskeletal system, which was confirmed by different pain discomforts in 67.3% of the examinees. Conclusions: Spinal alignment while attending childbirth is individually differentiated and in every case non-ergonomic. Identifying explicitly spinal overloads is difficult, but the most prevalent ones affect lumbar and cervical regions altogether. Spinal pain is frequently noted, both in junior and senior midwives, and is characteristic for midwives working in maximal movement ranges.
