Purpose : The purpose of this study was to investigate the effects of chin tuck exercise (CTE) on the craniovertebral angle (CVA), strength and endurance of deep cervical flexor (DCF) muscles in subjects with forward head posture(FHP). This study was performed on 30 subjects with FHP. Method : Thirty subjects were divided into two groups; modified CTE (n=15), conventional CTE (n=15). Both of the group performed the exercise 4 times a week for 6 weeks. The subjects performed CTE in two different methods; modified CTE, with device designed that help keep cervical lordois curve, and coventional CTE, without using device. The CVA was measured using Image software version. A pressure biofeedback unit was used to measure the strength and endurance of the DCF muscles. The data was analyzed by the paired t-test for comparing before and after changes of variables in each group and the independent t-test for comparing the between groups. Result : There was statistically significant difference of before and after strength and endurance of DCF muscles in modified CTE (p<0.05). There was statistically significant difference of before and after only endurance of DCF muscles in conventional CTE (p<0.05). There was statistically significant difference of between the two group in strength of DCF muscles (p<0.05). Conclusion : Muscle strength to stabilize the spine plays an important role in maintaining a good posture. Therefore, we suggest that the application of CTE with a device designed to maintain the lordotic curvature in the neck is likely to yield better outcomes in FHP subjects in future studies.

Objective : To investigate the causes for failed anterior cervical surgery and the outcomes of secondary laminoplasty. Methods : Seventeen patients failed anterior multilevel cervical surgery and the following conservative treatments between Feb 2003 and May 2011 underwent secondary laminoplasty. Outcomes were evaluated by the Japanese Orthopaedic Association (JOA) Scale and visual analogue scale (VAS) before the secondary surgery, at 1 week, 2 months, 6 months, and the final visit. Cervical alignment, causes for revision and complications were also assessed. Results : With a mean follow-up of $29.7{\pm}12.1$ months, JOA score, recovery rate and excellent to good rate improved significantly at 2 months (p< 0.05) and maintained thereafter (p>0.05). Mean VAS score decreased postoperatively (p<0.05). Lordotic angle maintained during the entire follow up (p>0.05). The causes for secondary surgery were inappropriate approach in 3 patients, insufficient decompression in 4 patients, adjacent degeneration in 2 patients, and disease progression in 8 patients. Complications included one case of C5 palsy, axial pain and cerebrospinal fluid leakage, respectively. Conclusion : Laminoplasty has satisfactory results in failed multilevel anterior surgery, with a low incidence of complications.

Background: This study was carried out to compare the effects of shoulder stabilization exercise and thoracic extension exercise including deep neck flexor exercise on posture and pain targeting physical therapists and occupational therapists with forward head posture. Methods: A total of 30 physical therapists and occupational therapists (15 males, 15 females), who are working in the nursing hospital at Daejeon, were randomly divided into a shoulder stabilization group (n=10), a thoracic extension exercise (n=10), and a control group (n=10), and 3 times were carried out for 8 weeks. Results: In the results of all measurements, 2 groups except for the control group showed a significant change in the recovery of forward head posture, and the should stabilization exercise group showed a relatively superior effect compared to the thoracic extension exercise group. Conclusions: These results of a study will be a basic data for the development of the forward head posture exercise therapy program.
