Brief summary

Background and aim: The use of smartphones, which has reached the level of addiction causes some physical and psychological health problems. The aim was to examine the musculoskeletal disorders of the neck and upper extremities of mobile phone addiction in a population of young adults. Methods: The study is a cross sectional research conducted on students of a university in İstanbul between December 2018-October 2020. The level of addiction was assessed with the Smartphone Addiction Scale Short Form (SAS-SF). The posture of participants was evaluated by New York Posture Rating Chart (NYPRC), mostly usage smartphone posture, forward head and myofascial trigger points were questioned according to Simon and Travel criteria. Mann-Whitney U test Pearson's chi-squared test were used for analyzing the data.

Design outcomes

Primary

MeasureTime frameDescription
Forward head postureBaselineForward head postures of the participants were evaluated by measuring the tragus to wall distance with a tape measure. For forward head posture, the patients were measured in standing position, leaning against the back wall, in free posture
Smartphone AddictionBaselineSmartphone Addictive Scale - Short Form (SAS - SF) that developed by Kwan et al. (2013), was used for the assessment of smartphone addiction. The cut off value of SAS-SF are 31 for men, 33 for women (6). The Turkish translated version of the SAS - SF is a reliable, consistent and valid instrument
PostureBaselineThe posture of the participants was assessed by using the New York Posture Rating Chart (NYPRC). In this evaluation method, postural changes that may occur in 13 different parts of the body (head, neck, shoulder, scapula, upper thoracic, waist, rips, abdomen, hips, knees, legs, feet and toe) are observed and scored. Each body segment was scored on the scale of; 5 (correct posture), 3 (slight deviation), or 1 (pronounced deviation). Higher points show better postural alignment
myofascial trigger pointBaselineThe presence of myofascial trigger points were questioned by Simon and Travel's criteria in the sternocleidomastoid, upper trapezius, levator scapula, rhomboid, infraspinatus and cervical extensor muscles. These criteria were -The presence of a tender spot in a taut band or nodules of skeletal muscle; -Subject recognition of pain upon palpation of a tender spot; -Subject referred pain pattern; -The presence of a local twitch response
