Purpose : to investigate the effectiveness of joint mobilization and myofascial release on the neck pain and to provide the effective treatment. Methods : Twenty-two subjects with neck pain participated in the experiment. All subjects were randomly assigned to a joint mobilization group(n=11) or a myofascial release group(n=11). Both groups received treatment for 15 minutes four times during 2 weeks. Cervical range of motion(CROM) instrument was used to measure range of neck motion, and Algometer was used to measure tenderness. All measurements of the subjects were measured at pre-treatment and post-treatment. Results : 1. The range of neck right side-bending motion of the myofascial release group was significantly increased(P<0.05), and the range of neck extension, right side-bending, left side-bending, right rotation motion of the joint mobilization group was significantly increased(P<0.05). 2. There was no significant improvement of tenderness in both groups(p>0.05). Conclusion : These data suggest that joint mobilization is more effective against increasing the range of motion than myofascial release, but myofascial release is more beneficial to tenderness than joint mobilization although it does not have a significant difference in the tenderness because there was a little improvement.

Objective : The purpose of this study was to estimate the reliability of cervical range of motion measurement in healthy adults using smart phone application and goniometer that can be easily applicated in clinical setting. Methods : The cervical range of motion was measured as the flexion, extension, right rotation, left rotation, right lateral flexion, and left lateral flexion. To measure the reliability of intra-rater and inter-rater reliability, the same examiner performed two measurements and the other examiner performed once, total measurement were performed three times. The order of tests was randomized and two examiners didn't know the results of measurements. Results : Thirty healthy adults were participated. The result of this study shows that there were are no significant differences in all movements except the right lateral flexion in comparison of average angle of smart phone application and goniometer. The intra-rater reliability of smart phone application and goniometer showed ICC as .841~.958 and the inter-rater reliability showed ICC as .720~.944 for all movements. Conclusion : These results suggest that smart phone application and goniometer have proven to be reliable in measuring the cervical range of motion. Smart phone application can be used as a useful tool in clinical setting due to fast and accurate measurements of cervical range of motion.

The purpose of this study was to apply the joint mobilization technique to the level of segments with pain and to the level of segments with hypomobility respectively and compare the immediate effects of the joint mobilization technique on the pain, the active cervical range of motion (ROM), and treatment satisfaction of patients with acute mechanical neck pain. After the baseline assessment, forty-two patients were randomized into two groups: a painful group ($n_1=21$) that received joint mobilization at the most painful cervical spine level and a hypomobile group ($n_2=21$) that received joint mobilization at the most hypomobile cervical level. The patients received an intervention that applied unilateral posterior-anterior gliding for 5 minutes and two repetitions of 10 times of active extension motion with distraction. In the Wilcoxon signed-rank test, the painful group and the hypomobile group were improved significantly in all pain variables (p<.001), while the painful group was improved significantly in the active cervical flexion (p<.001), extension (p<.001), left side-bending (p<.01), right side-bending (p=.001), left rotation (p<.001), and right rotation (p<.001). The hypomobile group was significantly improved in active cervical flexion (p=.001), extension (p<.001), left side-bending (p<.05), right side-bending (p=.001), left rotation (p=.001), and right rotation (p<.01) after intervention. In the Mann-Whitney U test, there was no significant difference in any of the dependent variables after the intervention between the two groups, but the painful group was slightly superior to the hypomobile group in all variables except for the right lateral flexion ROM and treatment satisfaction. These outcomes suggest that the cervical joint mobilization may be applied to either the level of painful segments or the hypomobile segments for the treatment of patients with acute mechanical neck pain.

Purpose: This study was conducted to investigate changes in the cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort following the wearing of a trunk brace during smartphone watching. Methods: To calculate the number of subjects for this study, an analysis with G^*Power was performed at a statistical power of 0.8, an effect size of 0.5, and a significance level of 0.05, based on the results of a preliminary experiment on five subjects. In total, 27 adult men and women were recruited who had been informed of the study's purpose and process and had agreed to participate. All subjects watched content on a smartphone for 20 minutes in the same posture and conditions while wearing and not wearing a trunk brace, and then their cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort were measured. Results: Compared to the non-wearing of a trunk brace, the wearing of a trunk brace resulted in a statistically significant smaller decline in cervical extension and right-side cervical rotation (p<0.05). When the subjects wore a trunk brace, their right- and left-side cervical and right-side lumbar pressure pain statistically significantly improved when compared to not wearing a trunk brace (p<0.05). They also perceived a significantly lowered level of comfort 20 minutes after wearing a trunk brace compared to immediately after wearing it (p<0.05). Conclusion: The trunk brace was effective in reducing declines in right-side cervical rotation and the occurrence of left- and right-side cervical and right-side lumbar pressure pain. The findings indicate the need to improve the perceived comfort of trunk braces.

Objective: The aim of this study was to compare sling exercise group to McKenzie exercise group in patients with chronic neck pain. Design: Two group pretest-posttest design. Methods: Twenty subjects who have chronic neck pain were randomly divided into sling exercise group (n=10) and McKenzie exercise (n=10). Sling exercise group (n=10) received sling exercise for 30 minutes per day, twice a week over a 4 week period. And the other group were exercised McKenzie exercise (n=8) for 30 minutes per day, twice a week over a 4 week period. Neck disability index (NDI), Visual analog scale (VAS), algometer, digital manual muscle tester (MMT) and cervical muscle strength and cervical range of motion (ROM) are closely measured to identify the effect of sling exercise and McKenzie exercise. Results: For NDI, VAS, algometer on both trapezius, both rotation of cervical muscle strength, both lateral flexion of cervical muscle strength, cervical extension of ROM and both lateral flexion of ROM were significantly increased after intervention in sling exercise group (p<0.05), For VAS, algometer on both trapezius, left (Lt.) rotation of cervical muscle strength, Lt. lateral flexion of cervical muscle strength, cervical flexion and extension of ROM and Lt. lateral flexion of ROM were significantly increased after than before intervention in McKenzie exercise group (p<0.05). Conclusions: These study outcomes clearly support the notion that sling and McKenzie exercise improved pain, Muscle strength and ROM of patients with chronic neck pain. These results suggest that sling and McKenzie exercise program is suitable for chronic neck pain.

Objective: This study aimed to evaluate the effects of the Kaltenborn-Evjenth concept of nerve mobilization combined with intermittent cervical segment traction (ICST) on pain, Neck Disability Index (NDI) scores, range of motion (ROM) and endurance in persons with cervical radiculopathy (CR). Design: Two-group pretest-posttest design. Methods: Thirty subjects participated in this study and were randomly assigned to two groups. The ICST group (n=15) was performed simultaneously with nerve mobilization and cervical traction for the segment with cervical pain at the same time. The intermittent cervical total traction (ICTT) group (n=15) performed nerve mobilization and cervical traction for the whole cervical area at the same time. In this study, outcome measures such as the Visual Analog Scale (VAS), NDI, ROM, endurance (cranio-cervical flexion test), and passive intervertebral motion performed before and 4 weeks after the experiment were compared to investigate the effects of each intervention. Results: In both groups, there were significant differences in the VAS, NDI scores, and endurance, and there were significant differences between the two groups except for endurance (p<0.05). In the ICST group, significant differences were found in all ROM, and in the ICTT group, significant differences were found in only extension, and there were significant differences between the two groups (p<0.05). Conclusions: The ICST group showed more improvement than the ICTT group in pain, NDI scores and ROM. Moreover, our findings show that the ICST could be used as a new strategy for manual therapy in persons with CR.

The purpose of this study was to estimate the cervical range of motion and the effects of massage and static stretching in their 20s of normal adult. One hundred participants(massage=50, stretching=50) with no musculoskeletal and nervous system problems volunteered for this study. Massage and static stretching were applied to sternocleidomstoid, scalenes, trapezius, semispinalis, splenius, suboccipital, multifidi and rotatores. Both groups received intervention for 3 times in a week. The time the intervention was applied was for 10minutes. Effleurage, petrissage and stripping technique was applied to massage group and static stretching technique was applied to stretching group. The cervical range of motion (CROM) instrument was used to measure eight cervical motions (suboccipital flexion, suboccipital extension, neck flexion and extension, and left and right lateral flexion, left and right rotation). As a result of making a statistical analysis of the data, the following findings were given: First, normal cervical range of motion revealed; suboccipital flexion($2.39^{\circ}$) and extension($38.36^{\circ}$), flexion($54.11^{\circ}$) and extension($69.39^{\circ}$), lateral flexion on left($43.50^{\circ}$) and right($41.28^{\circ}$), rotation on left($66.39^{\circ}$) and right($65.94^{\circ}$) in male and suboccipital flexion($5.14^{\circ}$) and extension($36.47^{\circ}$), flexion($55.92^{\circ}$) and extension($71.22^{\circ}$), lateral flexion on left($43.34^{\circ}$) and right($41.06^{\circ}$), rotation on left($69.38^{\circ}$) and right($68.63^{\circ}$) in female. Second, women had greater range of motions than men in suboccipital flexion, left and right rotation(p<0.05). Third, it showed significantly increasing cervical range of motion in all directions within groups following treatments but not between groups(p<0.05). Our results suggest that massage and static stretching are an appropriate intervention to increase cervical range of motion by muscle relaxation and stretching and may be provided a basis for future studies investigating the cervical range of motion.

Purpose : Neck pain is commonly experienced by both adolescents and adults. The purpose of this study was to measure neck disability index(NDI) and the cervical range of motion(CROM) following spinal manipulation and mobilization techniques. Methods : Thirty participants(manipulation=15, mobilization=15) with mild neck disability volunteered for this study. It was used to measure NDI with NDI questionnaire and six motions(neck flexion and extension, left and right lateral flexion, left and right rotation) with the CROM instrument. Independent t-test and paired t-test were used to estimate NDI and CROM, and compared left with right motions. Results : A significant decrease in NDI were found after spinal manipulation and mobilization treatment(p<.05). A trend toward increase in all cervical motions(flexion, extension, left and right lateral flexion, left and right rotation), after interventions, were revealed(p<.05). The significant differences were not found on NDI and CROM between the group(p<.05). It was presented asymmetric motions in cervical lateral flexion(p<.05) before and after treatment. Conclusions : Our results suggest that manipulation and mobilization probably provide at least short-term benefits for patients with mild neck pain. It is needed to be studied the factors and preventive methods influencing the asymmetric cervical motion.
