Purpose: New therapeutic approaches have emerged to improve gait ability in patients with brain damage, such as action observation learning (AOT), auditory cueing, motor imagery etc. We attempted to investigate the effects of AOT with auditory cueing (AOTAC) on gait function in patients with stroke. Methods: The eighteen stroke patients with a unilateral hemiparesis were randomly divided into three groups; the AOTAC, AOT, and control groups. The AOTAC group (n = 8) received training via observing a video that showed normal gait with sound of footsteps as an auditory cue; the AOT group (n = 6) receive action observation without auditory stimulation; the control group (n = 5) observed the landscape video image. Intervention time of three groups was 30 minutes per day, five times a week, for four weeks. Gait parameters, such as cadence, velocity, stride length, stance phase, and swing phase were collected in all patients before and after each training session. Results: Significant differences were observed among the three groups with respect to the parameters, such as cadence, velocity, stride length, and stance/swing phase. Post-hoc analysis indicated that the AOTAC group had a greater significant change in all of parameters, compared with the AOT and control groups. Conclusion Our findings suggest that AOTAC may be an effective therapeutic approach to improve gait symmetry and function in patients with stroke. We believe that this effect is attributable to the change of cortical excitability on motor related to cortical areas.

Effort to improve balance ability in the field of rehabilitation has been constantly issued and developed up to now. A variety of subcomponent of postural control including function and cognition should be needed in many body systems and be complicatedly linked to each system. In South Korea, although decreased postural dysfunction due to neurological or musculoskeletal disorders has been well documented, we do not have many experience and knowledge of vestibular rehabilitation for maintain and improve balance function. In the United States, vestibular physical therapy is already acknowledged as clinical subspecialty by American Physical Therapy Association. However, there is no curriculum subject related to vestibular rehabilitation in standard education of physical therapy and no specialist who has clinical experience and knowledge of this realm. Therefore, we reviewed general information and basic knowledge of vestibular rehabilitation such as current state of vestibular disorder in South Korea, pathology, major causes of vestibular dysfunction including peripheral vestibular disorders, vestibular neuritis, benign paroxysmal positional vertigo, and central disorder, evaluation of vestibular dysfunction, and treatment for vestibular dysfunction new approaches. We expect that physical therapist in South Korea recognize clinical significance of vestibular exercise and that clinical concern and research will be begun in near future.

This study investigated the differences in the effect of repetitive transcranial magnetic stimulation (rTMS) between patients with and without the involvement of Broca's area (IBA).The medical records of 20 stroke patients treated with rTMS for non-fluent aphasia were reviewed. Patients completed the Korean version of the Western Aphasia Battery (K-WAB) pre- and post-rTMS. Magnetic resonance T1-weighted images of the brain were analyzed using SPM12 software. Montreal Neurological Institute templates and Talairach coordinates were used to determine Broca's area involvement and segregate patients into 2 groups: IBA and non-IBA (NBA) groups. All statistical analyses were performed using the SPSS software.Twenty subjects were included in the study. The K-WAB scores revealed improvements in the total subjects and IBA and NBA groups. There were no statistical differences between the IBA and NBA groups in the ΔK-WAB scores of aphasia quotient, fluency, comprehension, repetition, and naming. The rTMS was positive for non-fluent aphasia patients, but there was no significant difference in effectiveness depending on the IBA. Further research with a larger number of patients is needed to identify the differences in the effect of rTMS on the IBA.

PURPOSE: This study examined the effects of trunk side shift exercise on the Cobb's angle. METHODS: Fifty-eight subjects (control group=30, scoliosis group=28) were enrolled in this study. The idiopathic scoliosis groups were divided randomly into two groups, a side shift exercise (SSE) group, and a trunk stabilization exercise (TSE) group. The SSE group performed side shift exercise on the developed chair training for eight weeks. The TSE group performed trunk stabilization exercise. A one-way ANOVA test was carried out to compare the results within the idiopathic scoliosis patient group before and after the exercises based on the different exercise methods. RESULTS: The Cobb's angles were compared among control group and SSE group and TSE group. As a result, there was a significant difference from SSE group and TSE group(p=0.000), but there were no significant differences between the SSE and TSE groups (p=0.085). CONCLUSION: Side shift exercises are effective in improving the Cobb's angle. Therefore, the use of the side shift exercise chair designed in this study can replace general exercise either at work or during studies. Therefore, this method is easily accessible for busy modern students who are exposed to scoliosis or spinal disorders due to a pattern of inactivity.

PURPOSE: This study was conducted to investigate the effects of variations in arm swing during gait on movement of the trunk and pelvis. During the gait task, the angle of the trunk and pelvic rotation were analyzed according to arm swing conditions. METHODS: Seventeen healthy males participated in this study. All subjects were analyzed for gait on a treadmill three times each under three different types of arm swing conditions – natural arm swing, restricted arm swing using a phone, restricted swing in both arms. 3-D motion analysis systems were used to collect and analyze the kinematic data of trunk and pelvic movements, and repeated one-way ANOVA was used to compare the trunk and pelvic kinematic data and symmetry index. The level of significance was α=0.05. RESULTS: The results showed kinematic differences in trunk and pelvic during gait based on the arm swing conditions. Specifically, there were significant differences in trunk rotation, left and right trunk rotation and symmetry index of trunk rotation during gait among the three arm swing conditions. ROM was used to calculate a symmetry index (SI) based on the average left and right trunk rotation in which a value closer to zero indicated better balance. The SI obtained for arm swing restricted with the phone was closer to –1 than the other conditions. CONCLUSION: Restricted arm swing due to use of a phone had the possibility to induce instability of postural control while walking, which could be seen to suggest a risk of falling during gait.

Purpose: Myofascial syndrome is a chronic muscle pain caused by repetitive motions with stress-related muscle tension. This study aimed to investigate the validity and reliability of the evidence for diagnosing myofascial pain syndrome in trapezius muscle using a pressure algometer and surface electromyography. Methods: The experiments were performed using a total of 10 subjects, and the target locations were determined by means of a pressure algometer in the right upper trapezius muscle. The part with the lowest pain value as the trigger point and the part with the highest pain value as the non-pain trigger point were selected for measuring the locations. The median frequency and average frequency were measured in those locations with electromyography. To check the muscle fatigue, the upper trapezius muscle was moved up and down for 2 seconds at 5-second intervals in 30 seconds. The measured values were evaluated using the independent paired t-test and MannWhitney U-test. Results: The median frequency at the non-trigger point (13.7) was significantly higher than that at the trigger point (7.3). Furthermore, the mean frequency (14.7) at the non-trigger point was significantly higher than that at the trigger point (6.3). Conclusion The results showed the correlations between the trigger points of the muscle pain and frequency analysis of surface electromyography. Thus, this study may be possible to use as a diagnostic tool for myofascial pain syndrome.

Objective: This study examined the correlation between dysarthria and aspiration to determine if dysarthria can predict aspiration in stroke patients. Methods: The medical records of 176 patients with first stroke, who underwent a videofluoroscopic swallowing study (VFSS) and Urimal test of articulation and phonology (U-TAP) at the same time between January 2012 and December 2015 in the authors’ hospital, were reviewed retrospectively. The correlation between the penetration aspiration scale (PAS) score and U-TAP score was analyzed in all patients. The mean PAS score and frequency of each PAS score in the dysarthria group and non-dysarthria group were compared. In addition, the aspiration was analyzed based on the severity of dysarthria in the dysphagia group. All statistical analyses were performed using SPSS software. Results: The correlation between the PAS score and U-TAP score was not statistically significant in all the subjects.The mean PAS score was 3.46±5.52 and 3.07±5.49 in the dysphagia and non-dysphagia group, respectively. The mean PAS score of the dysphagia group was higher than that of the non-dysphagia group. On the other hand, it was not statistically significant. In addition, there was no significant difference in the frequency of the PAS scores between the two groups. The aspiration was compared with the severity of dysarthria according to the U-TAP score; there was no statistically significant difference. Conclusion No correlation was observed between dysarthria and aspiration in stroke patients. In addition, there was no difference in the frequency of aspiration with or without dysarthria. According to the results of this study, aspiration cannot be predicted by dysarthria in stroke patients. Therefore, each diagnostic test and assessment should be performed for each symptom.

BACKGROUND: Persistent organic pollutants (POPs) are toxic materials that cannot be broken down naturally and that easily accumulate in the body. Although several studies have attempted to reveal the effects of POPs on the endocrine and nervous system and on cancer, few studies focus on the relationship between low-dose POPs and public health. We attempted to find a relationship between the level of POPs and common gastrointestinal symptoms, including abdominal discomfort, diarrhea, and constipation. METHODS: We recruited 121 subjects who visited Kyungpook National University Hospital for a health screening. Plasma concentrations were evaluated for 40 kinds of POPs including 17 types of polychlorinated biphenyls and 23 types of organochlorine pesticides. Furthermore, the Korean version of the Rome III criteria was used to identify gastrointestinal symptoms. RESULTS: Our results showed that abdominal discomfort had an inverse relationship with several polychlorinated biphenyls. Moreover, an inverted U-shaped relationship was observed between abdominal discomfort and several other organochlorine pesticides including p,p'-dichlorodiphenyldichloroethane and p,p'-dichlorodiphenyltrichloroethane, and the effects of these pesticides on abdominal discomfort were similar to that of organochlorine pesticides on obesity and metabolic syndrome. CONCLUSION: Our results suggest that mild and unspecified gastrointestinal symptoms with no clear cause could be related to POPs levels.

Transposition of the island pedicle flap is a versatile method of mobilizing tissue from a relatively distant reservoir and moving it across intervening tissue. Advantages are the similar color and texture to those of the affected area, the minimal donor scar, the increased viability with local blood supply, and the potential to camouflage scars into natural skin lines or cosmetic units. In a 73-year-old woman, the lesion of a basal cell carcinoma on her left nasal ala was removed by Mohs micrographic surgery and the resultant defect was reconstructed by transposition of the island pedicle flap. In our case, there were no significant complications and the final result was satisfactory in both functional and cosmetic aspects. Through our experience, we can confirm that transposition of the island pedicle flap is another alternative for the reconstruction of nasal alar defects.
