Abstract
This study was conducted to identify the effects of mobilization, deep cervical flexor training(DCFT), and mixed training on the mobility of adults with nonspecific neck dysfunction. Thirty adults with nonspecific neck dysfunction were selected as subjects through the Korean version of the neck disability index (K-NDI) and classified into a joint mobilization group, deep neck flexor training group, and mixed group. They were then subjected to an intervention for four weeks. To examine the effect of the intervention on the range of motion of the neck, the range of motion of the neck before and after the experiment was measured. As the result of the four-week intervention, the flexion and extension of the joint mobilization group and the mixed group increased significantly compared to that of the deep neck flexor training group (p < .05). As a result, joint mobilization and mixed training for nonspecific neck dysfunction were effective in increasing the range of motion of the neck. Based on these results, an intervention program including joint mobility can be effective in treating adults with nonspecific neck dysfunction caused by various factors.
Highlights
With the gradual development of information technology, in Korea, the state of dependence on smartphones has increased continuously from 11.1% in 2012 to 20% in 2019 [1]
In musculoskeletal disorders, the number of patients diagnosed with VDT syndrome, which includes neck-related diseases such as myofascial pain syndrome and forward head posture, was 4.58 million in 2009 and 2012. 5.53 million and 6.34 million in 2019, an increase of 1.38 times compared to 2009, accounting for the largest share [2]
Musculoskeletal disorders occurring in the neck include neck pain, cervical strain, sprain, facet joint syndrome, ruptured cervical disk, and myofascial pain syndrome [6], common symptoms caused by these diseases include neck pain, decreased joint range of motion, and muscle
Summary
With the gradual development of information technology, in Korea, the state of dependence on smartphones has increased continuously from 11.1% in 2012 to 20% in 2019 [1]. 5.53 million and 6.34 million in 2019, an increase of 1.38 times compared to 2009, accounting for the largest share [2]. The exact pathological cause of neck disease has not been elucidated yet, incorrect posture caused by prolonged work in wrong posture, wrong sleeping posture, and bad posture habits changes the length of postural maintenance and antigravity muscles in a stable state. It causes disorders in the head and neck bones [5]. Musculoskeletal disorders occurring in the neck include neck pain, cervical strain, sprain, facet joint syndrome, ruptured cervical disk, and myofascial pain syndrome [6], common symptoms caused by these diseases include neck pain, decreased joint range of motion, and muscle
