Purpose: This study examined the effects of the forward head posture and tension type headache on neck movement among office workers. Methods: The subjects were 6 male and 21 female patients composed of a forward head posture group, forward head posture group with a tension type headache and a normal group. Each group consisted of 2 males and 7 females. The cranio-vertebral angle of the head and the angle of motion of the neck were measured. SPSS 23.0 was used for data analysis and one-way ANOVA was performed for the mean comparison of the neck movements in the three groups. Results: The participants had a limitation in the movement of all necks between the forward head posture group and forward head posture with tension type headache group compared to the normal subjects. The forward head posture with tension headache group had limited neck extension and lateral bending compared to the forward head posture group. Conclusion: Office workers have limitations in the movement of the neck when they are accompanied by forward head posture and tension headache. In particular, when accompanied with a tension headache, there is a restriction on the neck extension and side bending. This study is expected to provide basic data for the relief of tension headache and the treatment of forward head posture in office workers.

Purpose: Muscle imbalance between upper trapezius (UT) and serratus anterior (SA) during arm elevation is a factor causing shoulder dysfunction. However, there is no study to compare the muscle activities of the UT and middle deltoid (MD). The purpose of this study was to compare the muscle activities of the UT and MD between with and without elevation of shoulder girdle (ESG) during shoulder abduction. Methods: The subjects without (control group=9) or with (ESG group=8) participated in this study. The muscle activities of the UT and MD were measured using a electromyography during $90^{\circ}$ shoulder abducted position in both group. The data in middle of 3-second of the 5-second periods were used. The mean value of three trials was used in the data analysis. For each muscle, independent t-tests were performed to compare for group differences. Results: The muscle activity of UT was significantly greater in ESG group, compared to that of the control group (p<0.05). The muscle activity of MD was significantly smaller in ESG group, compared to that of the control group (p<0.05). Conclusion: These findings showed that low muscle activation of MD as well as SA may contribute to hyperactivity of UT during arm elevation.

Objective : The aim of this study was to investigate the neuroprotection effect of estrogen on brain atrophy following cerebral infarction. Method : All animals in this study were classified into 4 groups; ovariectomy group (OVXgroup), cerebral infarction group (INF group), combination ovariectomy and cerebral infarction group (OVX + INF group), and naturally intact group for control data (NOR group). Cerebral infarction was made by Chen's method with some modification. Ovariectomy was performed by Wayforth's method. Experimental data for each group was collected at 15 days, month, 3 months, and 6 months after starting observation. Serum $17{\beta}-estradiol(E2)$ was determined by radioimmunoassay. Brain volume was measured and calculated with image analysis. Each brain was sliced at intervals of 2mm in chamber after 30 min of freezing in refregerater. Cerebral volume was obtained by sum of volume of each slice level, which was mean $area{\;}{\times}{\;}2mm$. Results : Cerebral ischemia was found to decrease the serum concentration of $17{\beta}-{\;}estradiol(E2)$ and to inhibit the physiologically conpensatary function of the ovariectomized rats. Also we found that deprivation of estrogen have resulted in more severe cerebral atrophy followed by cerebral infarction. Conclusion : It is suggested that estrogen has a neuroprotection effect on cerebral atrophy following cerebral infarction.
