Background: This study aimed to investigate the effect of mobilization with movement (MWM) applied to the ankle joint, on the craniovertebral angle (CVA), pressure pain threshold, and neck disability index (NDI) in asymptomatic adults with a forward head posture (FHP). Methods: A total of 32 subjects with FHP were assigned to either the MWM group (N=16) or the cranio-cervical flexion exercise (CCFE) group (n=16). The CVA, pressure pain threshold and NDI were measured before and 4 weeks after the intervention. Results: A significant improvement in the CVA was observed in the MWM group (p<.05), whereas no significant changes (p>.05) were observed in the CCFE group. Both groups showed significant differences in the pressure pain threshold and NDI before and after the intervention (p<.05). Conclusion: The results of the study suggest that MWM applied to the ankle joint can effectively improve the CVA, pressure pain threshold, and NDI of adults with a forward head posture. Based on this study, the ankle MWM technique for dorsiflexion can be used as an objective research method for additional studies targeting FHP patients in the future.

Previous studies have reported that deep neck flexor (DNF) exercise can improve neck problems, including neck pain, forward head posture, and headache, by targeting the deep and superficial muscles of the neck. Despite the prevailing opinion across studies, the benefits of DNF can vary according to the type of neck problems and the outcome measures adopted, ranging from positive outcomes to non-significant benefits. A meta-analysis was conducted in this study to assess conclusive evidence of the impact of DNF exercise on individuals with neck problems. We used PUBMED, MEDLINE, NDSL, EMBASE, and Web of Science to search for primary studies and the key terms used in these searches were "forward head posture (FHP)," "biofeedback," "pressure biofeedback unit," "stabilizer," "headache," and "neck pain." Twenty-four eligible studies were included in this meta-analysis and were coded according to the type of neck problems and outcome measures described, such as pain, endurance, involvement of neck muscle, craniovertebral angle (CVA), neck disability index (NDI), cervical range of motion (CROM), radiographs of the neck, posture, strength, endurance, and headache disability index. The overall effect size of the DNF exercise was 0.489. The effect sizes of the neck problems were 0.556 (neck pain), -1.278 (FHP), 0.176 (headache), and 1.850 (mix). The effect sizes of outcome measures were 1.045 (pain), 0.966 (endurance), 0.894 (deep neck flexor), 0.608 (superficial neck flexor), 0.487 (CVA), 0.409 (NDI), and 0.252 (CROM). According to the results of this study, DNF exercise can effectively reduce neck pain. Thus, DNF exercise is highly recommend as an effective exercise method for individuals suffering from neck pain.

PURPOSE: The purpose of this case report was to determine the effect of therapeutic exercise on posture, pain, and muscle activity in two patients with forward head posture (FHP). METHODS: A-31-year-old male (patient A) and a 19-year-old women (patient B) presented with FHP, neck pain, and headache. The therapeutic exercise program consisted of cervical mobilization, deep cervical flexors strengthening, and cervical extensors stretching, for 40 min/d, 2 d/week, for 8 weeks. Neck pain (VAS), neck disability (NDI), cervical range of motion (CROM), lateral view of cervical spine X-ray (indicating the FHP), and asymmetrical neck and shoulder muscular activity ratio were measured before, after 4 weeks, and after 8 weeks of corrective exercise. RESULTS: VAS and NDI decreased in patients A and B after exercise compared to before the program. CROM increased in patients A and B at flexion, extension, side bending, and rotation after exercise compared to before the program. FHP decreased in patients A and B at distance after exercise compared to before the program. In addition, asymmetrical neck and shoulder muscles activity ratio improved in patients A and B after exercise compared to before the program. CONCLUSION: We demonstrated in a case report that therapeutic exercise increases ROM, decreases pain and disability of neck, FHP, and asymmetry muscle activity ratio in patients with FHP. These finding have clinical implications for therapeutic exercise in patients with FHP.

Purpose: The purpose of this study was to assess the effect of using smartphones for tele-rehabilitation on head position and neck dysfunction in workers with visual display terminal (VDT) syndromes over a four-week period. Methods: Sixteen VDT workers volunteered to participate in stretch exercise and posture education sessions. The subjects were divided into three groups as follows: five subjects in the visit group (VSG), six subjects in the video group (VEG), and five subjects in tele-rehabilitation group (TG). The subjects in all the groups performed the exercises three days per week for four weeks. Cranial rotation angle (CRA), craniovertebral angle (CVA) measurement, and neck disability index (NDI) tests were performed before and four weeks after the intervention. Results: No significant difference in the CRA and CVA variables was found among groups. No significant difference in the CRA variable was found within each group. A significant difference in the CRA variable was found in the VSG after the four-week intervention. No significant difference in NDI was found among the groups. The NDIs among all the groups were significantly decreased after the intervention when compared with the NDIs measured before the intervention. Conclusion: The use of smartphones in the tele-rehabilitation of VDT workers with neck pain was found to be as effective on neck function as the conventional intervention method. The tele-rehabilitation of VDT workers with neck dysfunctions may be presented as an alternative way.

Purpose: The aim of this study was to investigate and compare the risk factors focusing on the neck and lower back between general workers (GW) and mild intellectual disability workers (MIDW) in the automobile manufacturing industry. Methods: A total of 32 participants were required for this study design to achieve 80% power, 0.9 effect size, and an alpha level of 0.05. Each group consisted of 16 subjects, including GW and MIDW. Pain levels in the neck and lower back were measured for all participants using the visual analog scale (VAS). A dual digital inclinometer was used to measure the range of motion (ROM) in the neck and lower back three times, and the average was used for analysis. The independent t-test was used to compare between the wo groups. Cohen's d effect analysis was employed to determine the effect size. The significant level was set at 0.05. Results: In the MIDW, neck pain was significantly higher, and left cervical flexion was significantly decreased compared with the GW. There was no significant difference in lower back pain between the MIDW and GW. However, both lumbar flexion and extension, as well as lateral flexion, were significantly reduced in the MIDW compared with the GW. Conclusion: This study reveals that MIDW working in the automobile manufacturing industry have a greater risk of neck pain, limitation in left cervical flexion, and overall restriction in the ROM of the lower back compared with GW.

Purpose : This study aimed to apply muscle relaxation exercise and ultrasound therapy as an effective treatment method for tension headache patients by comparatively analyzing the muscle mechanical properties, neck disorder index, and headache impact test. Method : The subjects were classified into three groups based on the intervention received: the therapeutic ultrasound (n=15, group I), placebo therapeutic ultrasound combined with the suboccipital release (n=15, group II), and therapeutic ultrasound combined with suboccipital release (n=15, group III) groups. The intragroup and intergroup differences in muscle mechanical properties, neck disability index, and headache impact test were compared and analyzed. Result : The comparison and analyses of the changes in muscle tone and post hoc analysis revealed statistically significant intragroup decreases in the suboccipitalis and upper trapezius in groups I and III. Furthermore, statistically significant intergroup differences in the upper trapezius with a greater change in group III than in group II and suboccipitalis with greater changes in group III than in groups I and II were observed. The comparison and analyses of the changes in muscle stiffness and post hoc analysis revealed statistically significant intragroup decreases in the upper trapezius in group I and suboccipitalis in group III. Moreover, statistically significant intergroup differences in both muscles with greater changes in group III than in group II for both cases were observed. The comparison and analyses of the changes in the neck disability index and post hoc analysis revealed statistically significant intragroup decreases in all three groups and statistically significant intergroup differences with greater changes in group III than in groups I and II. The comparison and analyses of the changes in the headache impact test and post hoc analysis revealed statistically significant intragroup decreases in all three groups and a statistically significant intergroup difference with greater changes in group III than in groups I and II. Conclusion : The therapeutic ultrasound and suboccipital muscle release exercise effectively increased the flexibility of the muscles around the cervical vertebrae and reduced muscle tension and stiffness in tension-type headache patients.

Background: People who have painful neck have reduced proprioception in the neck. Reduced proprioception in the neck is related to the muscle spindle activity in the deep neck flexors. The aim of this study was to know that proprioception in the neck was increased by strengthening exercise of the deep neck flexors. Methods: Thirty subjects with chronic neck pain were randomly assigned to the experimental group (n=15) and the control group (n=15). Deep neck flexor muscle exercise with stabilizer were conducted for the study group three times a week for six weeks. Relocation errors in 30 degree rotation to the left were measured three times before and after intervention each. Results: Neck disability index were decreased in the experimental group (p<.05) but not in the control group (p>.05). Relocation errors were decreased in the experimental group after intervention (p<.05), but not in the control group (p>.05). Conclusions: Proprioception in the neck can be increased by the strengthening exercise of deep neck flexors in the subject with chronic neck pain.

The purpose of this study is to analyze the physical characteristic by directly measuring the wheelchair using disabled women. The subjects were 103 disabled women of wheelchair used women and between 20 - 55 years of age. The result of this study is as follow. There was a remarkable difference in the physical characteristic of wheelchair using disabled women due to their cause of disability. The cause of disability was classified into the 4 groups; poliomyelitis, spiral cord injury, muscular dystrophy, cerebral palsy. Poliomyelitis disability generally had a large horizontal area due to their strong upper body. People with spiral cord injury disability was shown to have the largest height, cervical height, waist back length, crotch length, knee length, The group of muscular dystrophy disabled people have the shortest length of body and also lean. The cebral palsy group of disabled people has an average length and height size body. A comparison of anthropometric measurements of wheelchair using disabled women with National Anthropometric Survey Korea(1997) was significant difference. People with poliomyelitis disability was shown to have a larger waist back length, neck point to breast point compared to normal women, but stature, crotch length was shorter compared to normal women. People with spiral cord injury disability had a similar in the vertical area. The group of muscular dystrophy and cebral palsy disabled people was short and smaller in general compared to a normal woman.

PURPOSE: The present study was conducted to improve the understanding of the Korean Standard Functional, Disability, and Health Classification (KCF) and its ease of use in the clinical domain of the musculoskeletal system by comparing, analyzing, and linking the KCF codes with items from patient-reported outcome measures (PROMs), which are currently mainly used to evaluate patients with neck, shoulder, waist, and knee pain. METHODS: The items of the most widely used PROMs, the Neck Disability Index (NDI), Disabilities of the Arm, Shoulder, and Hand (DASH) scores, Oswestry Disability Index (ODI), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the codes of the KCF were linked by two experts according to the linking rules. RESULTS: The concordance between the items of each of the PROMs and the KCF code linked by the two experts was NDI,86.4%86.4%, DASH 83.3%, ODI 92.0%, and WOMAC 80.7%. The NDI, DASH, and WOMAC indexes were found to comprise items corresponding to physical function, activity, and participation areas, and were linked to 22, 43, and 31 KCF codes, respectively. In addition to these two areas, the ODI included items related to environmental factors and was linked to 25 codes (duplicated codes are treated as one). CONCLUSION: This research can be used by adding the KCF code to the questions of the currently used evaluation tool. This coding can be easily applied and will contribute to the easy understanding of the KCF.
