Cervical traction effects its benefits by immobilizing the neck when it is used in a continuous manner from a reclining position. when used intermittently traction functions by elongating the neck and straightening the cervical Lordosis. This position of slight flexion opens the posterior articulations, widens the intervetebral foramina, disengages the facet surfaces, and elongates the posterior muscular tissues and Ligaments. The duration of traction is arbitary but the amount of traction is that which is tolerated by the patient and benefits the patient's problem. Application of traction in slingh flexion accomplishes the same separation with Less force and thus with Less discomfort experienced by the patient. But the effect of traction on the disks is debated.

Purpose : Radiation proctitis and radiation cystitis are frequent and problematic late complications in patients treated with radiation for the uterine cervix cancer. Authors tried to find out the better patient's position in high dose rate intracavitary radiation to reduce the radiation dose of bladder and rectum. Materials and Methods : In 13 patients, Foley Catheters were inserted to patient's bladder and rectum and were ballooned with radioopaque dye. After insertion of a tandem and two ovoids, semi-orthogonal anteroposterior and lateral films were taken in both lithotomy and supine position. The rectal point and bladder point were defined according to the criteria recommended in the ICRU Report 38 with modification. Using these films, all patients' bladder and rectal dose were calculated in both positions (the radiation dose of A point was set to 400 cGy). And also, the distance of bladder and rectum from uterine cervical os was calculated in both positions. Results : The average radiation dose of rectum was 240.7 cGy in lithotomy position and 278.3 cGy in supine position, and the average radiation dose of bladder was 303.5 cGy in lithotomy position and 255.8 cGy in supine position. After the paired t-test, the radiation dose of rectum in lithotomy position was marginally significantly lower than that in supine position, while the radiation dose of bladder in lithotomy position was significantly higher than that in supine position. On the other hand, the average distance between rectum and cervical os was 35.2 mm in lithotomy position and 32.3 mm in supine position. and the average distance between bladder and cervical os was 30.4 mm in lithotomy position and 34.0 mm in supine position. After the paired t-test. the distance between rectum and cervical os in lithotomy position was significantly longer than that in supine position, while the distance between bladder and cervical os in lithotomy position was significantly shorter than that in supine position. Conclusion : The radiation dose of bladder can be reduced in supine position and the radiation dose of rectum can be reduced in lithotomy position, so we can choose appropriate position in each patient.

This case report describes the effectiveness of cervical corrective exercises in a patient with cervical radiculopathy (CR) who experienced radicular pain, upper limb paresis, and limited functional activity. A 39-year-old male with cervical radiculopathy performed the cervical corrective exercises for reducing pain. Pain intensity, cervical posture, and active range of motion of cervical intersegmental spine motion were measured baseline, after 4 weeks, and after 8 weeks with self-reported questionnaire and radiographs. After 8 weeks of intervention, the patient demonstrated alleviated radicular symptoms, improved neck posture and active range of flexion and extension of the cervical intersegmental spine. Especially in the angle between the cervical vertebra 6 and 7, the angle was changed from $-4.69^{\circ}$ to $3.30^{\circ}$ during resting position after intervention. The present case indicates that the cervical corrective exercises might be a possible treatment to effectively reduce radicular symptoms, improve neck posture, and active cervical intersegmental motion for patient with CR.

Purpose: This study aimed to investigate the effects of sitting posture on cervical flexion angle and pain during smart phone use. Method: This research was performed on 10 adult female students who use smart phones regularly, Each of the two groups of participants used the provided smart phone for 20 minutes while maintaining the given default posture. The evaluation order was randomly selected and the two groups were photographed twice before and after the experiment and were asked to answer if they felt pain during or after the experiment. Result: First, both upright sitting position and vertebra bent position pre and post experiment readings showed significant statistical difference (p<.05). And it is shown to be a factor that induces pain around the neck via increase in neck flexion angle. Second, although there were no significant statistical difference between the pre and post experiment readings of the upright sitting position results and the vertebra bent position results, the vertebra bent position readings showed bigger changes to the neck flexion angle then the upright sitting position readings. Third, all participants from both groups claimed pain in all the tested postures of smart phone usage. Conclusion: Smart phone usage for an extended amount of time in all body postures may prove to have a negative effect making the "optimal" smart phone usage position as a controlled time with neck stretches included in between short sessions.

To determine whether position affects measured lung capacity of spinal cord injury patients. The study subjects were 45 patients with spinal cord injury (cervical level 15, thoracic level 15, lumbar level 15). Subjects were provided with a full explanation of the experimental procedures and all provided written consent signifying their voluntary participation. We used a spirometer (Spirometer, Micromedical Ltd, UK) to measure pulmonary function in the supine and sitting positions (straightened upper body at an angle of $90^{\circ}$). Forced vital capacity (FVC), forced expiratory volume during the first second (FEV1), tidal volume (TV), and maximum insufflation capacity (MIC) were also measured. FVC, FEV1, TV, MIC (%) were greater in the supine than in the sitting position for those with injury at the cervical or thoracic injury level. On the other hand, FVC, FEV1, TV, MIC (%) were lower in the supine position for those with an injury at the lumbar level. More attention should be paid to the effect of injury level on measured lung capacity.

Objective: The purpose of this study was to evaluate of various material of pillows by using biomechanical variables such as the cervical stability, head pressure distribution, and muscle activity. Method: Eight subjects participated in the experiment. Three different materials such as polyester sponge, memory foam and the buckwheat shell used for Korean traditional pillow were tested. Electro-goniometer, six channels of electromyography(EMG), ten channels of the head pressure sensors were used to measure the biomechanical responses. Surface electrodes were attached to the right/left semispinals capitis(RSC, LSC), the right/left sternocleidomastoid(RSM, LSM), the right/left upper trapezius(RUT, LUT). The cervical stability was evaluated by the angle deviated from the standing neck position. The head pressure distribution was evaluated by the pressure per unit area recorded on the sensors and the intensity of peak pressure. Electromyography(EMG) data were analyzed by using root mean square(RMS) and mean power frequency(MPF). Results: The buckwheat shell material showed a higher stability in the cervical spine then the other pillows during spine position. In terms of head pressure distribution, the memory form indicated the lowest pressure at supine position, buckwheat shell material indicated the lowest pressure during lying down to side, and polyester cushion recorded the highest pressure at all postures. Conclusion: The buckwheat shell material has a biomechanical advantage to maintain a healthy neck angle and reduce the pressure on the head, which means the buckwheat shell is a potential material for ergonomic pillow design. The pillow with memory form showed second best biomechanical performance in this study. Application: The shape of the buckwheat shell pillow and the characteristics of materials can be used to design the pillow preventing neck pain and cervical disk problems.

Purpose of this study was to compare the easiness of insertion of three Supraglottic airway devices(SADs) in a neutral and cervical neck collar position in a manikin setting. Three different SADs-Laryngeal Mask Classic (LMA), I-gel and Streamlined Liner of the Pharynx Airway(SLIPA) were applied. Thirty nine emergency medical technicians (EMTs) who are working in Korea 119 rescue services were taught briefly about the use of the LMA, I-gel and SLIPA in a manikin setting. The time to effective ventilation was shorter in I-gel ($10.5{\pm}2.2$, $11.4{\pm}5.7$) and SLIPA ($12.3 {\pm}5.1$, $12.0{\pm}6.8$) than LMA ($17.2{\pm}3.2$, $18.5{\pm}5.5$) in a neutral and cervical neck collar position, respectively(p<0.05). There was no difference between head positions in each of the airways. In conclusion, in the speed of insertion, I-gel and SLIPA were superior to LMA in the neutral and cervical collar setting of a manikin.

Purpose: The purpose of this study was to investigate the effects of a neck exercise using a proprioceptive neuromuscular facilitation (PNF) neck flexion and extension pattern on body balance in a progressive range of positions (supine, prone on elbow, and sitting), on numbness in the upper extremities, and on neck flexion motions in cervical myelopathy patients. Methods: One participant who was diagnosed with cervical myelopathy participated in this study. A reversal design (A-B-A') was used. The A and A' were the baseline period (no intervention), and B was the intervention period. The intervention used a neck extension pattern with a hold-relax technique and a neck flexion pattern with a combination of isotonic techniques in the supine position. Then, neck flexion and extension patterns were applied together with a reversal technique for stabilization, followed by a neck extension pattern with a combination of isotonic techniques in the prone position on the elbows. Finally, a neck flexion and extension pattern was used with a stabilizing reversal technique, and a neck extension pattern was applied with a combination of isotonic techniques in the sitting position for 60 minutes per day, 3 times per week for 8 weeks. To measure balance, numbness, and neck motion during neck flexion, the one-leg stand test and the visual analogue scale were used. Results: The right and left one-leg stand tests showed increased balance ability in the intervention phase. Upper extremity numbness was decreased in the intervention phase, and neck flexion motion was increased in the intervention phase. These increases were maintained after the intervention (Baseline II). Conclusion: These results suggest that a neck exercise using a PNF neck pattern with additional techniques in a progressive range of positions has a positive effect on cervical myelopathy patients for balance, numbness, and neck motion.

Background: As the increase of forward head position, we studied the change of thickness of deep cervical flexor (DCF) compared of with sternocleidomastoid (SCM). we measured and analysed the change of thickness of the neck flexor for forward head position and cranio-cervical flexion exercise (CCFE). Methods: Using a cross-sectional design, we conducted the study selecting 35 healthy adults (12 males, 23 females). We measured the craniovertebral angle (CVA), instructed them to perform the CCFE, and measured the DCF and SCM using ultrasonography during the contraction and relaxation period. Results: Intra-reliability of SCM is .96, longus capitis is .92 and longus coli is .97. we compared according to the change of forward head position, Correlation of DCF is .841, and DCF/SCM is .754 by significant positive correlation. At the comparison of CCFE and Resting muscle thickness, SCM and DCF is .00, DCF/SCM is .68. Conclusion: There is a strong positive correlation between the change amount of DCF and DCF/SCM as the increase of CVA.
