Summary Measures

The purpose of this cross-sectional study was to compare the observed associations between upper trapezius muscle activity, as estimated with several summary measures obtained from surface electromyography (EMG), and self-reported neck/shoulder pain among a sample of 231 manufacturing workers. EMG methods used in this study included mean root-mean-square amplitude, the amplitude probability distribution function (APDF), EMG gaps analysis, and clustered exposure variation analysis. The observed seven-day prevalence of neck/shoulder pain was 13.9%. Of the EMG summary measures, only the 90 th percentile of the APDF was significantly associated with symptoms, with crude and adjusted odds ratios of 2.57 (1.02–6.49) and 2.78 (1.07–7.21) per natural log unit, respectively. This study was largely inconclusive due to the similarity in the distributions of the summary measures between symptomatic and non-symptomatic participants, and explicit measures of posture and repetition may produce stronger associations with symptoms.

Abstract Objective To determine whether a composite metric of arm elevation and trapezius activity (i.e. neck/shoulder load) is more strongly associated with the 2-year course of neck and shoulder pain intensity (NSPi) among construction and healthcare workers than each exposure separately. Methods Dominant arm elevation and upper trapezius muscle activity were estimated in construction and healthcare employees (n = 118) at baseline, using accelerometry and normalized surface electromyography (%MVE), respectively. At baseline and every 6 months for 2 years, workers reported NSPi (score 0–3). Compositions of working time were determined for arm elevation (< 30°; 30–60°;  > 60°), trapezius activity (< 0.5%; 0.5–7.0%; > 7.0%MVE), and a composite metric “neck/shoulder load” (restitution, low, medium, and high load). Associations between each of these three compositions and the 2-year course of NSPi were determined using linear mixed models. Results Associations between exposure compositions and the course of NSPi were all weak and in general uncertain. Time spent in 0.5–7.0%MVE showed the largest and most certain association with changes in NSPi during follow-up (β = − 0.13; p = 0.037; corresponding to a −0.01 change in NPSi every 6 months). Among pain-free workers at baseline, medium (β = − 0.23; p = 0.039) and high (β = 0.15; p = 0.031) neck/shoulder load contributed the most to explaining changes in NSPi. Conclusion The composite metric of neck/shoulder load did not show a stronger association with the course of NSPi than arm elevation or trapezius activity alone in the entire population, while some indications of a stronger association were found among those who were pain-free at baseline.

Upper Trapezius Muscle

Karakteristik gangguan kesehatan yang disebabkan oleh aktivitas mengetik dengan komputer cenderung pada cidera tingkat rendah yang muncul seiring waktu akibat sikap kerja yang salah, lama dan berulang, salah satunya adalah Myofascial Pain Syndrome (MPS) otot upper trapezius dengan gejala utama nyeri tekan dan terdapat nodul pada otot. Penelitian ini bertujuan untuk mengetahui hubungan sikap kerja saat mengetik  terhadap MPS otot upper trapezius pada pekerja kantor di Denpasar. Jenis penelitian ini adalah penelitian observasional analitik dengan rancangan cross sectional yang dilaksanakan pada bulan Maret 2018. Pengambilan sampel dilakukan dengan teknik purposive sampling dengan sampel berjumlah 53 orang. Pengukuran MPS otot upper trapezius dilakukan dengan pemeriksaan fisioterapi. Pengukuran sikap kerja saat mengetik dengan metode Rapid Upper Limb Assesment (RULA). Uji hipotesis yang digunakan adalah Chi Square Test untuk menganalisis signifikansi hubungan antara sikap kerja saat mengetik dengan MPS otot upper trapezius. Pada perhitungan analisis data, diperoleh nilai p sebesar 0,000 sehingga p < 0,05. Maka dapat disimpulkan bahwa terdapat hubungan yang signifikan antara sikap kerja saat mengetik terhadap MPS otot upper trapezius pada pekerja kantor di Denpasar. Kata Kunci: Sikap kerja mengetik, myofascial pain syndrome upper trapezius
