“…Many studies proofed, that NVG devices do not only allow pilots to enhance their visual capacity, but also come at the cost of increased mass leading to NVG-induced neck strain [21, 22]. Interestingly, in our study, helmet weight alone may have had an impact on neck pain and we refer to results of a study by Sovelius et al who reported, that helmet weight itself seems to induce more muscle strain than NVG [39]. Higher weight of the helmet has a more significant effect on cervical muscle loading then the lighter NVG, which alters the center of gravity [39].…”

Higher weight of the helmet has a more significant effect on cervical muscle loading then the lighter NVG, which alters the center of gravity [39]. Moreover, neck pain prevalence might increase by using NVG more frequently, as Adam found a threshold value of 150 NVG hours, after which 90% of helicopter aircrew report neck pain [16].…”

“…Specific training strategies and further research is essential to reduce the pain prevalences among helicopter pilots and crewmembers. According to Sovelius et al better muscle conditioning programs, enhanced muscle coordination and head support strategies are required to prevent neck injuries caused by the extra mass of the helmet [39].…”

BackgroundFlight-related neck, shoulder and low back pain are the most common musculoskeletal disorders among helicopter pilots and their crewmembers, thus becoming a growing concern. Information on the combined prevalence of these types of pain and related risks are scarce. The aim of this study was therefore to estimate pain prevalence and to evaluate potential risk factors for neck pain among helicopter pilots and crewmembers within the armed forces, the airborne police and airborne rescue organizations in Austria.MethodsAmong a cohort of 104 helicopter pilots and 117 crewmembers (69.8% compliance), demographics, flying experience, use of Night Vision Goggles (NVG), helicopter type flown, prevalence and intensity of musculoskeletal symptoms (pain was defined as any reported pain experience, ache or discomfort) were collected by an online-based questionnaire.ResultsFor helicopter pilots the 12-month prevalence of neck pain was 67.3%, followed by low back (48.1%) and shoulder pain (43.3%). Among crewmembers, the 12-month pain prevalence were 45.3, 36.8 and 30.8% among the neck, lower back and shoulder, respectively. During this period, 41.8% of these helicopter pilots had experienced 8–30 pain days in the areas of neck (45.7%), shoulder (37.8%) and lower back (42.0%) whereas 47.8% of crewmembers self-reported 1–7 days of neck (54.7%), low back (44.2%) and shoulder (44.4%) pain in the previous year. The 3-month prevalence of neck pain was 64.4% followed by low back (42.3%) and shoulder pain (38.5%) for helicopter pilots. Among crewmembers, 41.9% suffered from neck, 29.9% from low back and 29.1% from shoulder pain the previous 3 months. Multivariate regression analysis revealed NVG use (OR 1.9, 95% CI, 1.06–3.50, p = 0.032), shoulder pain (OR 4.9, 95% CI, 2.48–9.55, p < 0.001) and low back pain (OR 2.3, 95% CI, 1.21–4.31, p = 0.011) to be significantly associated with neck pain.ConclusionsThe 12- and 3-month prevalence of neck, shoulder and low back is considerably high among both, helicopter pilots and crewmembers confirming the existence of this growing concern. The use of NVG devices, shoulder and low back pain in the previous 12 months represent independent risk factors for neck pain. These findings highlight the need for longitudinal studies.

“…The staff members were fully engaged in the treatment of patients, near all of the patients had only physical examination and recompression treatment and other examinations such as magnetic resonance imaging, computerized tomography or neurophysiologic techniques, which could be helpful in diagnosis and evaluation of the outcomes [24], [25], were nearly absent. No autopsy was performed for all the death cases.…”

BackgroundDecompression illness (DCI) is a major concern in pressure-related activities. Due to its specific prerequisite conditions, DCI is rare in comparison with other illnesses and most physicians are inexperienced in treatment. In a fishery area in northern China, during the past decade, tens of thousands of divers engaged in seafood harvesting and thousands suffered from DCI. We established a hyperbaric facility there and treated the majority of the cases.Methods and ResultsA total of 5,278 DCI cases were admitted in our facility from February 2000 through December 2010 and treated using our recompression schedules. Cutaneous abnormalities, joint and muscular pain and neurological manifestations were three most common symptoms. The initial symptom occurred within 6 h after surfacing in 98.9% of cases, with an overall median latency of 62 min. The shorter the latent time, the more serious the symptoms would be (P<0.0001). Nine cases died before recompression and 5,269 were treated using four recompression schedules, with an overall effectiveness rate of 99.3%. The full recovery rate decreased with the increase of the delay from the onset of symptoms to the treatment (P<0.0001).ConclusionsDCI presents specific occurrence rules. Recompression should be administered as soon as possible and should never be abandoned irrespective of the delay. The recompression schedules used were effective and flexible for variety conditions of DCI.

“…Surface electromyography (sEMG) is commonly used to estimate muscular demands during mock or modified work tasks (Anton et al, 2001;Sood et al, 2007;Blackstone et al, 2008;Sheikhzadeh et al, 2008;Soveliues et al, 2008;Albayrak et al, 2007;Cort et al, 2006). It is an appealing method for occupational task assessment due to the quantity of information contained in the sEMG signal, and the ease of collecting sEMG in the field.…”

Neck Muscle Strain When Wearing Helmet and NVG During Acceleration on a Trampoline

Abstract: Helmet weight alone had a large effect on muscular workload. The additional frontal weight of the NVG caused a further increase in the activity of cervical muscles that were already subjected to high strain.
