Abstract

BACKGROUND: Low back pain (LBP) is a common recurrent pathology among assembly chain workers. This population tends to spend most of the workday in a static standing posture and handling loads, with balance being essential for correct job performance. LBP is related to poorer postural control, so balance could be affected in this condition. METHODS: The purpose of the present study is to analyze the deterioration of static balance generated by work activity in a prolonged standing position. We assess sway with a pressure platform at three moments of the workday (before, during, and after work), comparing the different balance parameters in 22 manufacturing plant workers with (17) and without (5) LBP. RESULTS: -test showed no significant differences between the pain and non-pain groups' static balance parameters. Between the pre- and mid-workday captures, a two-way ANOVA with repeated measures showed a significant decrease in the medial-lateral center of pressure displacement with open eyes in workers with LBP. CONCLUSIONS: workers with low back pain do not show a greater deterioration in static balance than workers without pain during the workday.

  • MSDs predominantly affect the lumbar zone, shoulders, and arms, but also impact other body areas such as neck, wrists, and lower extremities.

    “Estas lesiones afectan predominantemente la zona lumbar, los hombros y los brazos [8], aunque también impactan otras áreas del cuerpo, como el cuello, las muñecas y las extremidades inferiores [8], [16], [27].”

    From Impact of ergonomics on work performance in the manufacturing industry: A systematic review (2025) · cites this paper as [27]

    The Introduction describes low back pain as a common recurrent MSD among workers and notes its high prevalence in metal-working environments. It mentions repetitive upper-limb movements, but does not say MSDs predominantly affect the shoulders or arms, or establish effects on the neck, wrists, or lower extremities. (LLM, conf=0.85)

    Experimental — accuracy not yet measured

  • MSDs are especially frequent in manufacturing industries and extend to various labor groups.

    “Además, no se limitan únicamente a estos sectores corporales, ya que su incidencia se extiende a diversos grupos laborales, siendo especialmente frecuentes en industrias manufactureras [26], [27].”

    From Impact of ergonomics on work performance in the manufacturing industry: A systematic review (2025) · cites this paper as [27]

    The Introduction says MSDs affect workers across all types of jobs and sectors, and reports a high prevalence of low back pain in metal-working and other employment sectors. It does not establish that MSDs as a whole are especially frequent in manufacturing compared with other industries. (LLM, conf=0.82)

    Experimental — accuracy not yet measured

  • Forced positions, especially flexion and rotation of the back, increase the risk of lumbar injuries.

    “las posiciones forzadas, especialmente la flexión y la rotación de espalda, incrementan el riesgo de lesiones lumbares [8], [27], [30].”

    From Impact of ergonomics on work performance in the manufacturing industry: A systematic review (2025) · cites this paper as [27]

    The Introduction (page not provided) says that awkward postures at work could cause or exacerbate low back pain. It does not identify back flexion or rotation as particular risks, or establish an increased risk of lumbar injuries rather than pain. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
