As ownership of electronic handheld devices increases in the United States, new information is needed about how posture may affect the neck and jaw joint when using these devices.
‘Women and shorter individuals bend their necks differently than men and taller individuals while handling their handheld electronic devices; this could be related to the higher incidence of neck and jaw pain experienced by women.’
Some evidence shows that using these devices, such as cells phones or tablets, in certain postures may influence both the neck and jaw, eventually causing the development of pain in both.
The study asked participants to hold and use electronic devices in five different postures while an X-ray was taken.
These postures ranged from a neutral position of sitting straight up to a fully reclined position, as if the participant were leaning back in a chair.
