“…Two studies have shown that degenerative changes, i.e., decreased vertebral body, intervertebral disc height, laxity and muscle weakness, together with neck fl exion and neck loads over time, can lead to changes in cervical lordosis [3,5]. A forward head posture develops when working in a sedentary position [30], which may lead to neck and head pain [16].…”

“…Inadequate and prolonged sitting postures, and workers' stressful conditions can cause a greater activation of the neck muscles [7,[9][10][11][12][13]. Besides, alteration of cervicothoracic mobility is correlated to respiratory dysfunctions [1,11,[14][15][16][17]. Monitoring respiratory frequency (f R ) during working activities is of great value because it is sensitive to cognitive load, emotional stress, pain, and discomfort.…”

“…A recent technological breakthrough in the area of wearables is promoting innovative applications for spine curvature monitoring [29] using inertial sensors [30,31], strain gauge [32], and optical sensors [33][34][35]. However, despite the great importance of neck posture monitoring to contrast adverse effects caused by long-term wrong postural habits (e.g., reduced productivity, absence from work and high utilization of health care services) only a few studies presented wearable sensors to monitor cervical spine movements [1,36,37]. Recent works proposed wearables based on piezoresistive sensors [38] and fiber Bragg grating (FBG) sensors [39] for monitoring single plane neck movements.…”

Musculoskeletal disorders are the most common form of occupational ill-health. Neck pain is one of the most prevalent musculoskeletal disorders experienced by computer workers. Wrong postural habits and non-compliance of the workstation to ergonomics guidelines are the leading causes of neck pain. These factors may also alter respiratory functions. Health and safety interventions can reduce neck pain and, more generally, the symptoms of musculoskeletal disorders and reduce the consequent economic burden. In this work, a multi-parametric wearable system based on two fiber Bragg grating sensors is proposed for monitoring neck movements and breathing activity of computer workers. The sensing elements were positioned on the neck, in the frontal and sagittal planes, to monitor: (i) flexion-extension and axial rotation repetitions, and (ii) respiratory frequency. In this pilot study, five volunteers were enrolled and performed five repetitions of both flexion-extension and axial rotation, and ten breaths of both quite breathing and tachypnea. Results showed the good performances of the proposed system in monitoring the aforementioned parameters when compared to optical reference systems. The wearable system is able to well-match the trend in time of the neck movements (both flexion-extension and axial rotation) and to estimate mean and breath-by-breath respiratory frequency values with percentage errors ≤6.09% and ≤1.90%, during quiet breathing and tachypnea, respectively.

Objectives/Hypothesis Suboptimal ergonomics during endoscopic sinus surgery can lead to considerable physical discomfort and fatigue for the surgeon. The purpose of this pilot study is to objectively evaluate the ergonomic positions of trainee and attending surgeons while performing functional endoscopic sinus surgery (FESS). Study Design Pilot prospective trial. Methods Six surgeons (two attendings and four trainees) performed FESS while wearing 11 inertial measurement units (IMUs) affixed to either side of each major joint. Screen placement was standardized to be 1 m directly in front of the surgeon and on the patient's left, 0–15° declined from the surgeons' eyes. Bed height was standardized such that the workspace was 0 to 10 cm below the elbows. IMU data were analyzed to calculate joint angles. Ideal joint angles (i.e., <10° for neck and trunk) were determined by the validated Rapid Entire Body Assessment tool. Subjects subsequently completed a modified National Aeronautics and Space Administration Task Load Index to assess cognitive and physical burden and pain. Student's t‐test was employed to detect differences between groups. Results Trainees adopted positions involving significantly greater neck flexion (9.90° vs. −6.48°, P = .03) and reported significantly higher frustration levels (3.04 vs. 1.33, P = .02) while operating than attendings. For both cohorts, increased operative time was significantly correlated with greater back flexion (r = 0.90, P = .02; r = 0.55, P = .04, respectively). Conclusions Our data suggest that trainees operate with higher risk neck postures than do attendings. These data indicate high‐risk operative postures may be borne of inexperience and present an opportunity for postural interventions at an early stage of training.
