Objectives Carpal tunnel syndrome (CTS) is common among office workers and limits functional hand ability and the ability to work. Carpal tunnel syndrome prevention programs implementation are still insufficient among office workers. In view of the fact that physical activity is the best method of preventing musculoskeletal complaints the aim of the study was to evaluate the effectiveness of prevention exercises protocol for hand and wrist pain among office workers. Material and Methods Study group consists form 62 office workers, reporting complaints of hand and wrist pain. Exercise group it was 49 subjects who performed the exercise protocol and the non-exercise group consisted of 13 subjects. An exercises program, consisting of 7 exercises. The program was planned for daily routine during 8 weeks. The effectiveness of the exercise program was assessed by physical parameters (hand grip and pinch grip strength, force of forearm muscles) and questionnaires (Visual Analog Scale pain scale, Carpal Tunnel Syndrome Symptom Severity Scale, and Carpal Tunnel Syndrome Functional Status Scale functional hand assessment questionnaires) were performed. Assessment was performed before and after the intervention. Results Statistical analysis of the data showed significant changes in the value of measured hand grip of the right hand (Z = –2.85, p < 0.01). For pinch grip, changes were significant for both the right (Z = –2.12, p < 0.05) and the left hands (Z = –2.35, p < 0.05). Functional performance improved significantly in bought groups. There was no statistically significant change in the intensity of experienced pain. Conclusions The results of the study indicate that performing a preventive exercise program regularly has an effect on increasing forearm muscle strength in a group of office workers. Office workers with symptoms of CTS who exercised regularly had higher results in hand grip and pincer grip strength. Exercises do not affect the level of pain complaints, which may indicate a more complex etiology of pain perception in this study group.

Objectives Investigate the impact of daily occupational walking steps on the progression of papillary thyroid cancer (PTC), a topic hitherto underresearched. Material and Methods The authors analyzed the data from 800 individuals with PTC across stages 0–IV. Participants were evenly divided into 2 distinct occupational groups: office workers and construction workers (N = 400 each). Data included comprehensive records of daily walking steps, demographic information, and clinical indicators. Pearson’s correlation coefficients or analysis of variance (ANOVA) were employed to assess the linkage between daily walking steps and PTC risk and stage, as well as associated biochemical markers. Results The analysis revealed a significant inverse relationship between daily walking steps and PTC risk. A higher frequency of daily steps was associated with reduced chances of PTC onset and a lower diagnostic stage of the disease. This protective effect of physical activity was particularly pronounced in the construction worker cohort. Subsequent evaluations showed that construction workers who consistently logged higher daily steps had markedly lower levels of thyroid-stimulating hormone (TSH), free triiodothyronine, free thyroxine, thyroid peroxidase antibody, thyroglobulin antibody, and thyroglobulin (Tg). Notably, daily walking steps exhibited a strong inverse correlation with body mass index (BMI), age, PTC volumes, and levels of TSH and Tg across both occupational groups (ρ < –0.37). The increase in daily steps was associated with the reduction in PTC stages (p < 0.001). Conclusions The research underscores the potential benefits of increased daily walking steps, suggesting that they may play a protective role in reducing PTC risk and moderating its progression.

Wstęp Badania epidemiologiczne wykazały, że osoby pracujące przy monitorach ekranowych (visual display units – VDU) częściej skarżą się na zaburzenia mięśniowo-szkieletowe (musculoskeletal disorders – MSDs). Celem badania była ocena związku między MSDs a cechami indywidualnymi pracowników i czynnikami związanymi z pracą. Materiał i metody Badanie przeprowadzono wśród 1032 osób używających VDU w pracy. Zebrano dane dotyczące cech indywidualnych badanych (wiek, staż pracy, historia palenia, aktywność fizyczna) i czynników związanych z wykonywaną pracą (najczęstsze czynności, pozycja ciała). Oceniono też zgodność środowiska pracy z normą ISO 9241-5:1998. W celu dokładnej analizy występowania MSDs przeprowadzono bezpośrednią obserwację osób badanych i ich stanowisk pracy. Skorygowane ilorazy szans (adjusted odds ratios – ORa) obliczono z zastosowaniem modelu regresji logistycznej. Wyniki Częstość występowania MSDs była stosunkowo wysoka (53%). Zaobserwowano statystycznie istotną zależność między MSDs a płcią żeńską (OR = 2,832, 95% przedział ufności (confidence interval – CI): 2,178–3,683), wiekiem powyżej 50 lat (OR = 2,231, 95% CI: 1,236–4,026) i dłuższym narażeniem na VDU – zarówno w wyniku dłuższego stażu pracy (10–14 lat: OR = 1,934, 95% CI: 1,301–2,875; ≥ 15 lat: OR = 2,223, 95% CI: 1,510–3,271), jak i większego wymiaru czasu pracy (30–39 godz./tydzień: OR = 1,537, 95% CI: 1,087–2,273). Analiza wieloczynnikowa potwierdziła, że nieodpowiednio zorganizowane stanowisko pracy jest czynnikiem ryzyka MSDs (ORa = 2,375, 95% CI: 1,124–5,018). Wnioski Występowanie zaburzeń mięśniowo-szkieletowych jest istotnie związane z indywidualnymi cechami pracownika i właściwościami środowiska pracy. Odpowiednio zorganizowane stanowiska pracy mogą znacznie zmniejszyć częstość występowania MSDs u osób pracujących przy VDU. Med. Pr. 2016;67(6):707–719

Background Epidemiological studies have shown that employees working with visual display units (VDU) are more likely to complain about musculoskeletal disorders (MSDs). The aim of this study has been to evaluate associations among MSDs and individuals and work-related factors. Material and Methods A total of 1032 VDU workers were assessed about their personal (i.e., age, working history, smoking history, physical activity) and work-related factors (i.e., predominant job tasks performed, work posture). Work environment was evaluated regarding fulfillment of the standard ISO 9241-5:1998. The investigation required a direct observation of participants (in order to accurately assess the prevalence of MSDs) and workstations. Adjusted odds ratios (ORa) were calculated by means of the logistic regression model. Results Prevalence of MSDs was relatively high (53%). In general, MSDs were significantly associated with female sex (OR = 2.832, 95% confidence interval (CI): 2.178–3.683), age ≥ 50 years old (OR = 2.231, 95% CI: 1.236–4.026), longer exposure to VDU, both as working history (10–14 years: OR = 1.934, 95% CI: 1.301–2.875; ≥ 15 years: OR = 2.223, 95% CI: 1.510–3.271) and working time (30–39 h/week: OR = 1.537, 95% CI: 1.087–2.273). Inappropriate workstation design was confirmed by the multivariate analysis as a risk factor for MSDs (ORa = 2.375, 95% CI: 1.124–5.018). Conclusions Musculoskeletal disorders were significantly associated with individual factors as well as characteristics of work environment. An appropriate design of workstations may significantly reduce their prevalence amongst VDU workers. Med Pr 2016;67(6):707–719
