“…23 The stature loss in the administrative MPOs (2.80 mm) was smaller than that observed in other studies (from 5.6 to 6.3 mm) that have analyzed stature changes while sit‐stand and sitting during a regular office workday. 24 , 25 In contrast, others have demonstrated comparable stature losses during a short period of sitting of 15 min (from 2.95 to 3.47 mm 26 ;) and 1h (from 1.5 to 2.6 mm 27 ;). Possibly, differences in office chair types and the amount of sit‐stand activity, as well as other body movements during the working day, may have clouded comparisons between studies.…”

Objective Military personnel has a large prevalence of back pain, especially those involved in patrolling routines, as they wear heavy protective equipment. Patrolling includes long periods of sustaining the protective equipment in a sitting or in a motor vehicle (motorcycle or car). Thus, understanding spinal loading of military police officers after patrolling by car (CAR; n = 14), motorcycle (MOT; n = 14), and administrative (ADM; n = 14) routines is relevant to establish preventive strategies. Methods The torque of the trunk and working and anthropometric characteristics were assessed to explain spinal loading using stature variation measures. Precise stature measures were performed before and after a 6 h journey (LOSS) and 20 min after a resting posture (RECOV). The trunk extensor (PTE BM −1 ) and flexor (PTF BM −1 ) muscles' isometric peak torque were measured before the working journey. Results The LOSS was similar between CAR and MOT (4.8 and 5.8 mm, respectively) after 6 h of patrolling. The ADM presented the lowest LOSS (2.8 mm; P < .05). No changes in RECOV between groups were observed ( P > .05). Vibration may explain the greater spinal loading involved in patrolling in comparison to the ADM. A GLM analysis revealed that BMI was the only explanatory factor for stature loss. No independent variables explained RECOV. The ability of the trunk muscles to produce force did not influence LOSS or RECOV. Conclusions Military police officers involved in patrolling may require greater post‐work periods and strategies designed to reduce the weight of the protective apparatus to dissipate spinal loading. The external load used in patrolling is a relevant spinal loading factor.

“…20 Duduk dengan menopang dagu biasanya disertai dengan keadaan tulang belakang yang membungkuk sehingga lama kelamaan dapat menyebabkan trauma tulang belakang. 21 Selain itu, semakin lama durasi tekanan yang diterima pada dagu, maka semakin besar pula tekanan yang dapat dapat menimbulkan gejala temporomandibular disorders. 1 Dalam masa pertumbuhan, kebiasaan yang tidak benar, seperti menopang dagu, dapat membuat bentuk wajah berubah.…”

Kebiasaan buruk postur tubuh merupakan suatu kebiasaan posisi tubuh yang menyimpang dari posisi normal. Kebiasaan buruk postur tubuh ini mengakibatkan perubahan pada komponen sistem muskuloskeletal dan dalam jangka waktu yang lama dapat menyebabkan ketidakseimbangan pada sistem tersebut. Sendi temporomandibula memiliki hubungan dengan regio servikal membentuk suatu sistem "kranioserviko-mandibula". Gangguan pada kranioservikomandibula yang berdampak pada postur tubuh biasanya adalah gangguan pada sendi temporomandibula. Salah satu gejala dari gangguan sendi temporomandibula adalah adanya bunyi kliking. Tujuan dari penelitian ini adalah untuk mengetahui ada atau tidaknya hubungan antara kebiasaan buruk postur tubuh dengan bunyi kliking sendi temporomandibula. Metode: Jenis penelitian adalah deskriptif dengan pengamatan yang dilakukan secara cross-sectional pada mahasiswa Fakultas Kedokteran Gigi Universitas Padjadjaran angkatan 2014. Sampel penelitian dipilih dengan metode purposive sampling.Penelitian dilakukan pada 71 mahasiswa Fakultas Kedokteran Gigi Universitas Padjadjaran dengan memberikan kuesioner mengenai kebiasaan buruk postur tubuh dan pemeriksaan bunyi kliking pada sendi temporomandibula. Hasil: terdapat hubungan yang signifikan antara kebiasaan buruk postur tubuh dengan bunyi kliking pada sendi temporomandibula dengan keterkaitan sebesar 8,45%. Kebiasaan buruk postur tubuh yang paling sering dilakukan oleh mahasiswa Fakultas Kedokteran Gigi Universitas Padjadjaran adalah menunduk saat menggunakan ponsel dengan persentasi sebanyak 63 orang. Simpulan: pasien dengan kebiasaan buruk postur tubuh dapat mengalami gangguan pada sendi temporomandibula dengan gejala berupa bunyi kliking. Kata kunci: Kebiasaan buruk, postur tubuh, bunyi kliking sendi temporomandibula Correlation between bad posture habits and clicking sound on temporomandibular joint at students of faculty of dentistry padjadjaran university ABSTRACT Introduction: Bad posture habits are a habit of body position that deviates from the normal position which result in changes in the musculoskeletal system components and over a long period of time can cause an imbalance in the system. Disorders of the temporomandibular joint are one of the disorders of the musculoskeletal system. One symptom of temporomandibular joint disorder is the presence of clicking sounds. The purpose of this study is to explaine a relationship between bad posture habits with clicking sounds joints temporomandibula. Methode: This research uses descriptive observational method with cross sectional approach. The study was conducted on 71 students of Dentistry Faculty of Padjadjaran University by giving questionnaires about bad posture habits and checking of clicking sounds on temporomandibula joints using stethoscope. The data obtained were analyzed using Spearman's Rank correlation test. Results: there was a significant association between FHP, sitting habits with chin rest, sitting habits and slouching in a chair, head resting on a table, carrying bags on one side, standing o...

“…The first step in the development of the tool was the computation of the vectors for each joint which triggered the joint angle measurement, using equation (1). The reference point which is the neutral position was then established such that any deviation from the neutral position results in awkward postures according to the recommendations of the H&S professionals.…”

“…Prolonged sitting as well as poor seated postures has been found to be among the leading causes of low back pain and consequently, Work-Related Musculoskeletal Disorders (WMSDs). [1][2][3][4]. The sitting posture has been identified as the worst body posture that exists because it forces the spine to adopt a non-natural posture which negatively affects it [5].…”

et al. (2 more authors) (2018) Ergonomic assessment tool for real-time risk assessment of seated work postures.Abstract. This paper presents a posture assessment tool which utilizes the depth sensing techniques of a 3D imaging sensor for ergonomic risk assessment of seated worker's postures during controlled manual handling tasks. The tool, which has been developed to utilize the manual handling guidelines by the Health and Safety Regulators of some selected countries to measure and assess the postures of the upper bodies of operators, is tested to ascertain its effectiveness in assessing seated postures. The tool offers real-time posture assessment with real-time feedback to inform operators on when to adjust awkward seated postures. An experiment has been performed to record, assess and display the work postures of some seated operators in real-time with 'Good' and 'Awkward' postures identified with real-time feedback provided to the Operators. Results show that the tool can assess seated work postures in real-time which helps to reduce the rate of occurrence of Work-Related Musculoskeletal Disorders.
