This study examined the effects of action observations on the balance of patients with chronic stroke. The study period was between July 8, 2013 and August 10 2013. The participants were divided randomly into either the landscape picture observation group (n=20) and the action observation group (n=20). Each group observed the landscape pictures and video-recorded action-related balance for 5 minutes, respectively. Both groups had a balance training session for 10 minutes after the picture and video observations. The balance training sessions were repeated twice a day, three times a week for 6 weeks. As a result, significant improvement was noted in the action observation group than the landscape picture observation group for static balance and dynamic balance (p<.05). Consequently, the combination of action observation and balance training is believed to help improve the balance recovery for patients with chronic stroke.

Movements of the upper and lower limb muscles during five common gardening tasks were analyzed by using electromyography (EMG). Twenty adults aged in their twenties (mean age, $24.8{\pm}2.4$ years) were recruited. On two separate occasions, subjects visited a garden plot to perform digging, raking, troweling, weeding, and hoeing; all tasks were performed three times with 20 s intervals for each trial. To measure muscle activation during the five gardening tasks, surface EMG was used. Bipolar surface EMG electrodes were attached to eight upper limb muscles (bilateral anterior deltoid, biceps brachialis, brachioradialis, and flexor carpi ulnaris) or eight lower limb muscles (bilateral vastus lateralis, vastus medialis, biceps femoris, and gastrocnemius) on both sides of the body, for a total of 16 muscles. During the five tasks, photographs were taken of movement phases using a digital video camera. The right flexor carpi ulnaris and brachioradialis showed higher activation than the other upper and lower limb muscles measured during the tasks. All 16 upper and lower limb muscles were actively used only during digging. According to movement analysis of each activity, digging was classified into four movement phases, whereas raking, troweling, weeding, and hoeing each were divided into three movement phases. In each activity, there were high-impact phases in terms of muscle activation; the flexor carpi ulnaris and brachioradialis were identified as major muscles in each impact phase. This analysis may be used to generate biomechanical profiles of gardening tasks for practitioners when designing efficient gardening interventions for physical health or rehabilitation.

This study concerning the surface dose of eye and thyroid from panoramagraphy used thermoluminescent dosimeter (TLD) and photoluminescent dosimeter (PLD) to take measurements at ten hospitals in the Gwangju metropolitan area. The recommendations from ICRP 60 and ICRP 73 on the allowance standard for eye are 15 mSv and for thyroid is 1 mSv. The left eye TLD and PLD values are 0.19 mSv and 0.24 mSv respectively. The right eye TLD and PLD values are 0.23 mSv and 0.25 mSv respectively. Thyroid TLD and PLD values are 0.08 mSv and 0.25 mSv respectively and did not exceed the allowance standards(p<0.001). Also comparisons are made between TLD and PLD for each organ and PLD has higher dose measurements than TLD. There are statistically significant differences in left eye measurements and thyroid measurements (p<0.01). There is no significant difference in measurements for the right eye (p>0.05). The TLD and PLD measured dose from panoramagraphy instruments on eyes and thyroid from each hospital did not exceed the recommended dose from ICRP 60 for surface dose measurements. However, due to the probability of influence, consideration should be made for all levels of dose.

Objective : Cerebral vasospasm leading to cerebral ischemic infarction is a major cause of morbidity and mortality in the patients who suffer with aneurysmal subarachnoid hemorrhage. Despite adequate treatment, some patients deteriorate and they develop symptomatic vasospasm. The objective of the present study was to investigate the efficacy and clinical outcome of intraarterial nimodipine infusion on symptomatic vasospasm that is refractory to hemodynamic therapy. Methods : We retrospectively reviewed the procedure reports, the clinical charts and the transcranial doppler, computed tomography and digital subtraction angiography results for the patients who underwent endovascular treatment for symptomatic cerebral vasospasm due to aneurysmal SAH. During the 36 months between Jan. 2005 and Dec. 2007, 19 patients were identified who had undergone a total of 53 procedures. We assessed the difference in the arterial vessel diameter, the blood flow velocity and the clinical outcome before and after these procedures. Results : Vascular dilatation was observed in 42 of 53 procedures. The velocities of the affected vessels before and after procedures were available in 33 of 53 procedures. Twenty-nine procedures exhibited a mean decrease of 84.1 cm/s. We observed clinical improvement and an improved level of consciousness with an improved GCS score after 23 procedures. Conclusion : Based on our results, the use of intraarterial nimodipine is effective and safe in selected cases of vasospasm following aneurysmal SAH. Prospective, randomized studies are needed to confirm these results.

Purpose: Bell's palsy is a nerve paralysis disease that causes functional impairments and affects psychological and aesthetical parts. This study aimed to examine whether acupressure massage had positive effects on facial paralysis, subjective symptoms, and depression in Bell's palsy patients. Methods: This study was conducted by a nonequivalent control group pretest-posttest design. Participants were 60 patients with Bell's palsy. 30 patients were assigned to the experimental group and the remaining 30 patients were assigned to the control group. The period of the study was from October 1, 2008 to July 30, 2009. Acupressure massage was offered to the experimental group for 20 minutes per day for two weeks (a total of six times). A SPSS/Win 12.0 program was used for data analysis. Results: A difference in Digital Infrared Thermographic Imaging (DITI) between affected and unaffected sides was less in the experimental group having acupressure massage than in the control group and the score of the recovery of facial paralysis was also increased in the experimental group. The Facial Nerve Grade Systems by Brackmann score that is a more objective index showed a significant difference between two groups (F=26.81, p<.001). Subjective symptom and depression scores were more decreased in the acupressure massage group than in the control group. Conclusion: Based on the results, it is considered that acupressure massage can be applied to Bell's palsy patients as an alternative therapy. It can be used as an evidence-based East-West nursing intervention to improve patients' physical and mental functions.
