Factors Influencing Biomechanics during Pregnancy and Ergonomic Modifications to Alleviate Discomfort A Descriptive Review

Introduction

Pregnancy is a redefining phase of a woman’s life during which there are notable physiological changes to promote foetal growth and development. Biomechanics is one of the many areas of the body that are impacted by these changes [1]. Pregnancy frequently causes changed biomechanics that result in pain and musculoskeletal problems, especially in the lower back and lumbopelvic region [2]. Promoting maternal well-being requires an understanding of the elements that affect biomechanics during pregnancy and the implementation of appropriate ergonomic changes [1, 3].

Pregnancy-related alterations in biomechanics are caused by a wide range of reasons. The lower back and lumbopelvic area are subjected to more stress as a result of weight gain and the redistribution of body mass [1, 4]. Increased levels of relaxin are one hormonal shift that causes ligament laxity, which affects joint stability and may cause biomechanical abnormalities. Furthermore, pregnant women change their posture to accommodate the expanding uterus. This frequently results in an increased anterior pelvic tilt and lumbar lordosis, which affect spinal alignment and load distribution [5].

The biomechanics of pregnancy are significantly influenced by occupational circumstances as well. The risk of musculoskeletal discomfort rises with physical demands such lifting, standing, and repetitive jobs [1, 2]. Pregnant workers’ biomechanical stress at work is also exacerbated by inadequate support, rigid work schedules, and poor ergonomics [2, 4]. These elements emphasise the requirement for interventions and changes to be made in order to lessen the negative consequences on maternal well- being [3, 4].

Numerous ergonomic changes have been suggested as a solution to these issues in order to reduce discomfort and provide the best possible biomechanics throughout pregnancy. Women must be empowered to comprehend the significance of ergonomic adaptations, which requires education and understanding of the biomechanical changes that take place during pregnancy [3, 6]. Pregnant employees require certain workplace accommodations, such as supportive seats and flexible workstations [4, 7]. Supportive tools, including maternity belts and support bands, can give the lumbopelvic area additional support, easing pain and dispersing the stress on the lower back [3, 7].

Adapting activity can assist regulate biomechanical stress and minimise overexertion [6, 8]. These adaptations include good body mechanics and regular rest periods. Additionally, encouraging appropriate biomechanics and minimising stress-related pain depend on understanding the psychosocial elements of pregnancy and offering emotional support [6, 8].

The dynamic time of pregnancy is marked by a number of physiological changes that have an impact on a woman’s biomechanics. Discomfort and musculoskeletal problems, particularly in the lower back and lumbopelvic region, might result from these alterations. The wellbeing of pregnant women can be greatly enhanced by comprehending the elements influencing biomechanics during pregnancy and putting ergonomic changes into practise. This in-depth analysis looks at the multiple factors that affect a woman’s biomechanics while she is pregnant and explores ergonomic treatments that have been proven to minimise pain. Despite the rising volume of research on ergonomic treatments and pregnant biomechanics, there is still a need to integrate and synthesise what is already known. This in-depth review explores the multifaceted impacts on pregnancy biomechanics in an effort to plug this gap.

Pregnancy outcomes and Ergonomics

Several research papers have examined the impact of ergonomic stressors on pregnancy outcomes, particularly in relation to the risk of abortion.

• Ergonomic Stressors among Pregnant Healthcare Workers: This study emphasizes the impact of ergonomic stressors on pregnancy outcomes among healthcare workers. Factors such as heavy lifting, prolonged standing, and inadequate support can increase the risk of abortion [9].
• 2. Ergonomic Demands and Fetal Loss in Women in Welding and Electrical Trades: This Canadian cohort study investigates the association between ergonomic demands in welding and electrical trades and the risk of fetal loss. Exposure to physical stressors, such as lifting heavy objects or working in awkward postures, was found to be linked to an increased risk of abortion [10].
• Provisional Recommended Weight Limits for Manual Lifting During Pregnancy: This research focuses on the recommended weight limits for manual lifting during pregnancy. It suggests that exceeding these limits can impose excessive strain on the body, leading to complications and potentially increasing the risk of abortion [11].
• Design and Development of Ergonomic Workstation for Pregnant Workers in Readymade Garment Industry: This study addresses the importance of designing ergonomic workstations for pregnant workers in the readymade garment industry. Inadequate support, prolonged standing, and repetitive tasks without proper ergonomics can contribute to increased physical stress, discomfort, and potential risks, including the risk of abortion [12]. These studies collectively highlight the significance of addressing ergonomic stressors during pregnancy to mitigate the risk of abortion. Implementing appropriate safety practices, such as providing proper support, minimizing heavy lifting, and ensuring ergonomic workstations, can contribute to a safer and healthier working environment for pregnant women.

Ergonomic Actionables

• Provide adequate support to pregnant healthcare workers: Pregnant healthcare workers face physical stressors that can increase the risk of adverse pregnancy outcomes. Implementing measures such as reducing heavy lifting, ensuring appropriate rest breaks, and providing ergonomic equipment can help mitigate these stressors [9].
• Enhance safety measures in welding and electrical trades: Pregnant women working in these trades are exposed to physical stressors that can have detrimental effects on pregnancy. Implementing appropriate safety measures, such as minimizing exposure to hazardous substances, ensuring proper ventilation, and providing protective equipment, can help reduce the risk of fetal loss [10].
• Adhere to recommended weight limits for manual lifting: Manual lifting during pregnancy can pose a risk to both the pregnant woman and the fetus. Following recommended weight limits and providing assistance or mechanical aids for lifting heavy objects can help prevent excessive physical strain and potential complications [11].
• Design ergonomic workstations for pregnant workers in the garment industry: The design of workstations can significantly impact the comfort and well-being of pregnant workers. Implementing ergonomic principles, such as adjustable seating, appropriate workstation height, and proper support for the lower back, can help alleviate physical stress and reduce the risk of adverse pregnancy outcomes [12].

By incorporating these actionable changes, employers can create a safer and more supportive working environment for pregnant women. These changes prioritize the well-being of pregnant workers, reduce physical stressors, and promote optimal working conditions, ultimately contributing to the prevention of abortion and miscarriage.

The EU Directive 92/85/EEC on Pregnant Workers

In the European Union (EU), there are legislative measures in place to safeguard the health and safety of pregnant workers, with a particular emphasis on addressing ergonomic factors. The EU Directive 92/85/EEC on Pregnant Workers is a key regulation that outlines specific requirements to ensure the well-being of pregnant employees.

According to this directive, employers have a responsibility to conduct thorough assessments of the workplace to identify and mitigate any potential ergonomic hazards that could pose risks to the physical well-being of pregnant workers. These hazards may include factors such as awkward postures, repetitive movements, or excessive physical exertion that can lead to musculoskeletal strain.

The legislation also emphasizes the importance of providing comprehensive information, training, and guidance to pregnant workers regarding the potential ergonomic risks present in their working environment. Employers are encouraged to educate employees on proper ergonomics principles, including techniques for safe lifting, maintaining optimal posture, and utilizing ergonomic equipment or adjustments to minimize physical stress.

Furthermore, employers are obliged to make reasonable accommodations to the working conditions and tasks of pregnant workers, taking into account their specific ergonomic needs. This may involve providing ergonomic workstations with adjustable features, ergonomic seating options that promote proper alignment and support, and allowing for regular rest breaks to prevent excessive physical strain.

By adhering to these ergonomic guidelines and regulations, employers in the EU can effectively protect pregnant workers from the potential adverse effects of ergonomic stressors, ensuring their physical well-being and reducing the risk of musculoskeletal discomfort or injuries during pregnancy.

It is important to note that specific legislation and guidelines regarding ergonomics for pregnant workers may vary among EU member states. It is advisable to consult the relevant national regulations and guidelines for detailed information on ergonomics and the protection of pregnant workers in a specific country.
