Yet, effects of these text-entrymethods on other parts of bodies have not been reported, making it difficult to provide evidence for the development of ergonomic recommendations to prevent neck-shoulder pain. Moreover, mobilephone texting has been found to be significantly associated with neckpain (Berolo et al., 2011; Hegazy et al., 2016). Of note, pain assessmentis based on subjective reports from the participants. Still, there is a lackof objective evidence on postural or motor deviations in mobile deviceusers who have developed symptoms.Recently, some studies have found symptomatic subjects presentingwith greater head or neck flexion angles than healthy individualsduring smartphone texting (Gustafsson et al., 2011; Kim, 2015). However, these studies only focused on the cervical postures instead of the cervical postures instead of theentire spine during smartphone use. It is essential to understand thekinematics of adjacent spinal segments because some studies reportedthat the head/neck posture and cervicothoracic muscle activity couldbe affected by thoracolumbar postures during sitting (Caneiro et al.,2010; Falla et al., 2007; O'Sullivan et al., 2006). Further, the thoracicflexion angle rather than the craniovertebral angle has been suggestedto be a better predictor for neck-shoulder pain (Lau et al., 2010). Tsanget al. (2013a, 2013b) has found a high degree of movement coordination between the cervical and thoracic spines, which are morepotent in healthy individuals compared to individuals suffering fromchronic neck pain. Considering that the kinematics of cervical, thoracicand lumbar spines affect each other, it appears important to examinethe kinematics of the whole spine during smartphone texting tasks. Thisis further substantiated by a recent study showing that symptomaticindividuals were characterized by reduced coordination among proximal and distal muscles during smartphone texting (Madeleine et al.,2016). Therefore, studying the kinematics of the entire spine providesfurther insight into its potential role in the associations betweensmartphone use and chronic neck-shoulder pain.The aim of the present study was to investigate the spinal kinematics of the cervical, thoracic and lumbar regions during smartphonestexting and determine whether there would be differences (i) betweenusers with and without neck-shoulder pain, (ii) across bilateral (twohanded) smartphone texting, unilateral (one-handed) smartphonetexting, and two-handed computer typing. We hypothesized that userswith chronic neck-shoulder pain compared to pain-free users wouldshow increased cervical and thoracic spine flexion angles as well asmore static postures, based on previous research on desktop computersusers (Szeto et al., 2005). The second hypothesis was that users of bothgroups would display different kinematics patterns across the threetext-entry tasks in agreement with recent studies reporting differencesin muscle activation (Madeleine et al., 2016; Xie et al., 2016). The research findings can contribute towards developing recommendationsabout correcting postures for using these electronic devices that become very important in many people's daily lives in modern society.
