Neck pain and stiffness are prevalent among smartphone users. Maintaining a neck flexion angle of 0-15 degrees during smartphone use may reduce the risk of these disorders. Smartphone neck holders, designed to position phones at eye level, could help improve posture and alleviate neck strain. However, their ergonomic effectiveness and design remain unstudied, highlighting the need for research to ensure these devices promote neck health and prevent musculoskeletal pain.</span></span></span></span></div> Neck, Pain, Smartphone, Neck holder, 1 2 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-637-5&slc_lang=en&sid=1 Milad Gholami miladgholami65@gmail.com 100319475328460016536 0000000257311614 No School of Health, Student Research Committee, Arak University of Medical Sciences, Arak, Iran.
