Purpose: Cervical pain is caused mainly by a static position, lasting work, bad habits and stress, and is accompanied by pain in the upper trapezius. Traditionally, heat and traction, exercise, mobilization, manipulation have been used to treat cervical pain. This study examined the effect of stretching and manipulation (high-velocity low-amplitude: HVLA) on the pain and ROM in women with chronic cervical and upper shoulder pain. Methods: Fifty-two women diagnosed with chronic cervical and upper shoulder pain were enrolled in this study. Among them, 26 patients (experiment group) were managed by passive stretching and manipulation, and another 26 patients (control group) were treated with physical therapy intervention (hat pack: HP, transcutaneous electrical nerve stimulation: TENS, ultra sound: US). Each group made use of a Visual Analogue Scale (VAS) and the highly reliable (flextion: 0.92, extention: 0.99) cervical range of motion (CROM) to compare the possible changes in pain and ROM in the two groups after treatment. Results: In the experimental group, the pain decreased and the ROM has increased in all directions. In the control group, the pain decreased but the ROM was not changed in all directions. Conclusion: According to the results, passive stretching and manipulation is effective for increasing the ROM and decreasing the level of pain. Moreover, physical therapy intervention (HP, TENS, US) is effective for immediately decreasing the pain but has little effect on the ROM.
Objective : To determine the clinical and radiological safety of 15 consecutive patients managed with plate and screw fixation systems applied to the cervical lateral mass. Methods : 15 patients who underwent posterior cervical and T1 arthrodesis were reviewed from Jan 2002 to Dec 2004. Posterior cervical screw and plate fixation was applied on the lateral mass of the cervical spine. The authors have tried lateral mass screw fixation using a modified Magerl's technique [$20^{\circ}$ lateral and $20{\sim}30^{\circ}$ rostral screw trajectory] under preliminary radiological study. The average patient age was $39.73^{\circ}{\pm}11.00\;years$, and the average follow-up period was $9.73^{\circ}{\pm}6.77\;months$. Computed tomography scans taken after surgery were reviewed to confirm the attempted screw trajectory correct and safety. Results : Three of 93 lateral mass screws were malpositioned but clinical damage was not noted. Two of 8 pedicle screws on the T1 vertebrae were not placed on the correct pedicle area. Screw and plate loosening was observed in one case but was not subjected to an additional procedure because of maintained screw position observed during follow-up periods. Conclusion : The results of this study indicate that lateral mass screw fixation using the Modified Magerl's technique on the cervical lateral mass may provide safe and effective application on the patients. In addition, the chance of incorrectly placed screws was higher in T1 pedicle screw fixation than in lateral mass screw fixation of the cervical area.
Objective: To assess the efficacy of cervical open-door laminoplasty by hydroxyapatite implant insertion between the lamina and the lateral mass without suturing. Methods: All patients who underwent cervical open-door laminoplasty with C2/C7 undermining and insertion of hydroxyapatite implants from C3 to C6 were retrospectively evaluated for surgical time and neurological outcomes according to the Japanese Orthopaedic Association (JOA) score. To assess the alignment of the cervical spine and postoperative cervical pain, the C2-7 angle and a visual analogue scale score were used, respectively. Results: The population consisted of 102 women and 222 men ranging in age from 32 to 90 years. The average surgical time was 86 minutes. Fourteen of 1,296 hydroxyapatite implants were kept in place with sutures due to a weak restoration force of the hinge during surgery. No hydroxyapatite implant dislocation was detected on cervical computed tomography at 1 year after surgery. The average JOA score was $10.2{\pm}2.5$ before surgery and $14.6{\pm}2.8$ at 1 year after surgery. The average recovery rate was 61.8%. The average C2-7 angle at the neutral position was $7.1^{\circ}{\pm}6.2^{\circ}$ before surgery and $6.5^{\circ}{\pm}6.3^{\circ}$ at 1 year after surgery. Conclusion: This method enabled us to achieve minimal exposure of the lateral mass, prevention of lateral mass injury and dural injury, and a shorter surgical time while maintaining acceptable surgical outcomes. The idea that firm suture fixation is needed to prevent spacer deviation during cervical open-door laminoplasty may need to be revisited.

Background and Objectives : The common cause of voice disorders may be bad habits of phonation. faulty vocal habits might aggravate the voice disorder or make the dysphonia. Authors thought the analysis of faulty vocal habits might help to evaluate the causes and to choose the treatment methods in patients with dysphonia. Authors studied to evaluate which vocal habits were used in patients with dysphonia. Materials and Methods : Patients with dysphonia(N= 32) and person without dysphonia(N=20) were evaluated through pre-evaluation test by otolaryngologist and SLP. All subjects were evaluated accordingly Posture of body, expansion of cervical vein, excessive movements of thyroide prominence, position of tongue, tension of lower lip, tension of jaw, breathing pattern related with phonation. Results : In dysphonia group, we found 23 cases with tension of jaw, 15 cases with expansion of cervical vein, 7 cases with bad position of tongue, 3 cases with excessive movement of thyroid prominence and a lot of cases with bad breathing Pattern on Phonation. In control group, only 3 cases with bad position of tongue, 2 cases with tension of lower lip, 1 case with tension of jaw were found. Conclusions : More faulty vocal habits were found in dysphonia group. Authors thought faulty vocal habits could be the cause of dysphonia and aggravate the dysphonia and the control of vocal habits would be very important in patients with dysphonia.

Purpose: The aim of this study was to determine the kinematical characteristics of the pendular and the translational movements of each cervical vertebra at flexion and extension for understanding the mechanism of injury to the cervical spine. Methods: Twenty volunteers, young men (24~37 years), with clinically and radiographically normal cervical spines were studied. We induced two directional passive movements and then took X-ray pictures. The range of pendular movement could be measured by measuring the variation of the distance between the center point of two contiguous cervical vertebrae, and the range of translational movement could be measured by measuring the variation of the shortest distance between the center point of a vertebra and an imaginary line connecting the center points of two lower contiguous cervical vertebrae. The measurements were done by using a picture archiving and communicating system (PACS). Results: The total length of all cervical vertebrae in the neutral position was, on average, 133.66 mm, but in both flexion and extension, the lengths were widened to 134.83 mm and 134.79 mm, respectively. The directions of both the pendular and the translational movements changed at the $2^{nd}$ cervical vertebra, and the ranges of both movements were significantly larger from the $5^{th}$ cervical vertebra to the $7^{th}$ cervical vertebra for flexion and combined flexion and extension motion (p<0.05). Conclusion: The kinematical characteristics for flexion and extension motions were variable at each level of cervical vertebrae. The $1^{st}$ and the $2^{nd}$ cervical vertebrae and from the $5^{th}$ to the $7^{th}$ cervical vertebrae were the main areas of cervical spinal injury. This shows, according to "Hook's law," that the tissues supporting this area could be weak, and that this area is sensitive to injury.
This study was carried out to investigate the relationship between tensed mandibular positions, muscle tenderness and EMG activity, respectively, and between range of motion of the neck and sternocleidomastoid muscle tenderness. Under stressful conditions, most of people take several types of behavioral patterns. Two of them observed frequently are clenching of teeth and grasping of fist. Prolonged clenching or grasping should increase electromyographic activity of associated muscle, especially muscles of mastication and neck muscles and will cause hyperfunction, dysfunction and muscle pain. So it is necessary to relate EMG activity with muscle pain. The author performed routine clinical examination in 47 patients with Temporomandibular Disorders, especially for presence or absence of muscle tenderness. Mandibular rest position was used as a baseline reference position and two more position in which EMG activity was taken were rest postion with grasping of fist and teeth clenching position. BioEMG of Biopak system (Bioresearch Inc, USA) was used for measuring of integrated EMG in masseter, anterior temporalis, anterior belly of digastic muscle and sternocleidomastoid muscle. To measure of the range of neck motion. CROM(Cervical-Range-of Motion, USA) was used. The obtained results were as follows : 1. EMG activity of all muscles except in masseter was higher in grasping of fist than those in rest position and there were significant correlation in EMG activity between the two position except in anterior belly of digastric muscle. 2. When comparing EMG activity between tender and non-tender muscle, all examined muscles did not show any significant difference. From this data, we could conclude that EMG activity was generally not changed with tenderness, of couse, it might be dependent with degree of muscle tenderness. 3. Number of tender points in examined muscles was also not significantly different between in patients with masticatory muscle disorders and in patients with internal derangement. 4. Cervical posture and range of motion of the neck was not differed significantly between in patients with and in patients without tenderness of sternocleidomastoid muscle.
This study compared the effects of the initial head position (i.e., a HHP versus a relaxed head position) of subjects with and without a FHP on the thickness of the deep and superficial neck flexor muscles during CCF. The study recruited 6 subjects with a FHP and 10 subjects without a FHP. The subjects performed CCF in two different head positions: a HHP, with the head aligned so that the forehead and chin formed a horizontal line, and a relaxed head position (RHP), with the head aligned in a self-selected comfortable position. During the CCF exercise, the thickness of the longus colli (LCo) and the thickness of the sternocleidomastoid (SCM) were recorded using ultrasonography. The thickness of each muscle was measured by Image J software. The statistical analysis was performed with a two-way mixed-model analysis of variance. The thickness of the SCM differed significantly (p<.05) between the subjects with and without FHP. According to a post $h^{\circ}C$ independent t-test, the change in thickness of the SCM increased significantly during CCF in the subjects with FHP while adopting a HHP compared to that in the subjects without FHP. The change in thickness of the SCM was not significantly different between the two positions in subjects without FHP, and there was no significant change in thickness of the LCo muscle during the CCF exercise according to the initial position in both subjects with and without FHP. The results suggest that CCF should be performed in RHP to minimize contraction of the SCM in subjects with a FHP.
Background: Neck and jaw pain is common and is associated with jaw functional limitations, postural stability, muscular endurance, and proprioception. This study aimed to investigate the effect of jaw and neck pain on cranio-cervico-mandibular functions and postural stability in patients with temporomandibular joint disorders (TMJDs). Methods: Fifty-two patients with TMJDs were included and assessed using Fonseca's Questionnaire and the Helkimo Clinical Dysfunction Index. An isometric strength test was performed for the TMJ depressor and cervical muscles. The TMJ position sense (TMJPS) test and cervical joint position error test (CJPET) were employed for proprioception. Total sway degree was obtained for the assessment of postural stability. Deep neck flexor endurance (DNFE) was assessed using the craniocervical flexion test. The mandibular function impairment questionnaire (MFIQ) was employed to assess mandibular function, and the craniovertebral angle (CVA) was measured for forward head posture. Results: Jaw and neck pain negatively affected CVA (R2 = 0.130), TMJPS (R2 = 0.286), DNFE (R2 = 0.355), TMJ depressor (R2 = 0.145), cervical flexor (R2 = 0.144), and extensor (R2 = 0.148) muscle strength. Jaw and neck pain also positively affected CJPET for flexion (R2 = 0.116) and extension (R2 = 0.146), as well as total sway degree (R2 = 0.128) and MFIQ (R2 = 0.230). Conclusions: Patients with painful TMJDs, could have impaired muscle strength and proprioception of the TMJ and cervical region. The jaw and neck pain could also affect postural stability, and the endurance of deep neck flexors as well as mandibular functions in TMJDs.
In brachytherapy of uterine cervical cancer using the high dose rate remote afterloading system, it is of prime importance to determine the position of the radiation sources and to estimate the irradiation time. However, calculation with manual method is so time consuming and laborious, that authors designed a software as an aid to intracavitary radiotherapy Planning using the personal computer to obtain the precision of treatment without being too complicated for routine use. Optimal source arrangement in combination with dose rate at each specific points and irradiation time can be easily determined using this software in several minutes.
The C2 level is the transition zone between the cranial and cervical spine. Because of its high position and anatomic relationship to vital structures, exposing C2 is challenging and the surgical approach is controversial. We report a of a recurred chordoma in C2 portion, occupying the osseous intraspinal portion. The patient underwent total corpectomy of C3 and gross total removal of tumor by right submandibular approach 3 years previously. We performed a lateral extrapharyngeal approach from contralateral left side with resection C2 central portion followed by gross total removal of mass and placement of graft bone. Although there was transient hypoglossal nerve palsy postoperatively, the patient had full recovery.
