“…Epidemiological reports identify numerous risk factors for NP in the helicopter environment (e.g., night-vision goggles, flight hours, awkward postures; Adam, 2004;Ang & Harms-Ringdahl, 2006;Hiatt & Rash, 2011;van den Oord et al, 2010). Interactions between risk factors present a multifactorial, complex problem involving physical, psychosocial, and individual factor domains (Marras, 2008(Marras, , 2012NRC, 2001).…”

Objective Assess neck muscle activity for varying interactions between helmet, posture, and visual stress in a simulated “helo-hunch” posture. Background Military aviators frequently report neck pain (NP). Risk factors for NP include head-supported mass, awkward postures, and mental workload. Interactions between these factors could induce constant low-level muscle activation during helicopter flight and better explain instances of NP. Method Interactions between physical loading (helmet doffed/donned), posture (symmetric/asymmetric), and visual stress (low/high contrast) were studied through neck muscle electromyography (EMG), head kinematics, subjective discomfort, perceived workload, and task performance. Subjects ( n = 16) performed eight 30-min test conditions (varied physical loading, posture, and visual stress) while performing a simple task in a simulated “helo-hunch” seating environment. Results Conditions with a helmet donned had fewer EMG median frequency cycles (which infer motor unit rotation for rest/recovery, where more cycles are better) in the left cervical extensor and left sternocleidomastoid. Asymmetric posture (to the right) resulted in higher normalized EMG activity in the right cervical extensor and left sternocleidomastoid and resulted in less lateral bending compared with neutral across all conditions. Conditions with high visual stress also resulted in fewer EMG cycles in the right cervical extensor. Conclusion A complex interaction exists between the physical load of the helmet, postural stress from awkward postures, and visual stress within a simulated “helo-hunch” seating environment. Application These results provide insight into how visual factors influence biomechanical loading. Such insights may assist future studies in designing short-term administrative controls and long-term engineering controls.

“…Diese Nackenbeschwerden sind häufig mit Rückenschmerzen assoziiert (low back pain, LPB) [30] und werden in den jüngeren Studien häufiger beschrieben. Gründe für Nackenbeschwerden sind auch hier schwere Helmsysteme [24], der veränderte Kopf-Helm-Schwerpunkt durch das Tragen der NVG [24,28,29], ergonomische Gründe und die erzwungene Körperhaltung durch die Anordnung der Steuerelemente , Ganzkörpervibrationen im Sitzen, das Tragen einer schweren zusätzlichen Schutzbekleidung (Seenotausrüstung, ballistischer Schutz) und hohe Gesamtflugstunden [10].…”

ZUSAMMENFASSUNGIn dieser Studie gaben 14 % aller befragten 151 Jetpiloten und Waffensystemoffiziere (WSO) Nackenschmerzen an, weniger als in der vorliegenden flugmedizinischen Literatur. Am Untersuchungtag/Begutachtungtag waren alle LFF/WSO beschwerdefrei und die klinische Untersuchung der Halswirbelsäule (HWS) war regelrecht. Eine Erklärung dafür könnte die besondere Untersuchungssituation sein, ebenso die verwendete Definition des Nackenschmerzes bei Piloten, „significant flight-related neck pain“. Das sind Nackenschmerzen, die während des Flugdienstes auftreten und bis 48 Stunden nach dem Flug anhalten. In dieser Studie wird auch kurz auf die Häufigkeit und Gründe für Nackenbeschwerden bei Hubschrauberbesatzungen eingegangen.
