Objective: To assess the prevalence of lower urinary tract symptoms in chronic stroke patients and their impact on the perceived quality of life. Method: Thirty-eight patients who had suffered unilateral stroke at least 3 months prior to enrollment and showed no severe communication disorder were evaluated. Frequency of lower urinary tract symptoms and their impact on the quality of life were assessed using the Korean version of the International Prostate Symptom Score (IPSS) and an impact question. The correlation between each symptom score and the perceived quality of life was analyzed. Results: Overall, 89.5% of the participants were sympto-matic, of which 58.9% complained of moderate to severe symptoms. Nocturia, frequency, and straining were the most frequent symptoms and urgency was the least. The ‘quality of life’ score showed a high correlation with the total IPSS score (p<0.05). Logistic regression analysis showed that obstructive symptom was a significant predictor for dissatisfaction. Conclusion: The frequencies of lower urinary tract symptoms are high in chronic stroke patients. And they have significant influence on the perceived quality of life in chronic stroke survivors.

오병모,이재현,서한길,이우형,한태륜,정성욱,정호중,심영주 대한재활의학회 2018 Annals of Rehabilitation Medicine Vol.42 No.3

Objective To investigate the differences in hyolaryngeal kinematics at rest and during swallowing in the upright sitting (UP) and the lateral decubitus (LD) postures in healthy adults, and delineating any potential advantages of swallowing while in the LD posture.Methods Swallowing was videofluoroscopically evaluated in 20 healthy volunteers in UP and LD postures, based on the movements of hyoid bone, vocal folds, and the bolus head. Parameters included the Penetration-Aspiration Scale (PAS), horizontal and vertical displacement, horizontal and vertical initial position, horizontal and vertical peak position, time to peak position of the hyoid bone and vocal folds, and pharyngeal transit time (PTT). Results Nine participants were rated PAS 2 in the UP and 1 was rated PAS 2 in the LD (p=0.003) at least 1 out of 3 swallows each posture. The hyoid and vocal folds showed more anterior and superior peak and initial positions in the LD. In addition, swallowing resulted in greater vertical and smaller horizontal displacement of the hyoid in LD posture compared with UP. Time to peak position of the hyoid was shorter in LD. The maximal vertical and horizontal displacement of the vocal folds, and PTT were comparable between postures. Conclusion The results showed that the peak and initial positions of the hyoid and larynx and the pattern of hyoid movement varied significantly depending on the body postures. This study suggests that the LD posture was one of the safe feeding postures without any increased risk compared with UP posture.

김새현,오병모,한태련,정호중,심영주 대한재활의학회 2015 Annals of Rehabilitation Medicine Vol.39 No.4

Objective To identify the differences in the movement of the hyoid bone and the vocal cord with and without electrical stimulation in normal subjects.Methods Two-dimensional motion analysis using a videofluoroscopic swallowing study with and without electrical stimulation was performed. Surface electrical stimulation was applied during swallowing using electrodes placed at three different locations on each subject. All subjects were analyzed three times using the following electrode placements: with one pair of electrodes on the suprahyoid muscles and a second pair on the infrahyoid muscles (SI); with placement of the electrode pairs on only the infrahyoid muscles (IO); and with the electrode pairs placed vertically on the suprahyoid and infrahyoid muscles (SIV).Results The main outcomes of this study demonstrated an initial downward displacement as well as different movements of the hyoid bone with the three electrode placements used for electrical stimulation. The initial positions of the hyoid bone with the SI and IO placements resulted in an inferior and anterior displaced position. During swallowing, the hyoid bone moved in a more superior and less anterior direction, resulting in almost the same peak position compared with no electrical stimulation.Conclusion These results demonstrate that electrical stimulation caused an initial depression of the hyoid bone, which had nearly the same peak position during swallowing. Electrical stimulation during swallowing was not dependent on the position of the electrode on the neck, such as on the infrahyoid or on both the suprahyoid and infrahyoid muscles.

Factors Associated With Compliance With Viscosity-Modified Diet Among Dysphagic Patients

심재승,오병모,한태륜 대한재활의학회 2013 Annals of Rehabilitation Medicine Vol.37 No.5

Objective To investigate compliance with a viscosity-modified diet among Korean dysphagic patients and to determine which factors are associated with compliance.Methods We retrospectively reviewed medical records of patients who had been recommended to use thickeners in the previous videofluoroscopic swallowing study (VFSS). Among 68 patients, 6 were excluded because tube feeding was required due to deterioration in their medical condition. Finally, 62 patients were included in the study. Patient compliance was assessed using their medical records by checking whether he or she had maintained thickener use until the next VFSS. To determine which factors affect compliance, the relationship between thickener use and patient characteristics, such as sex, age, inpatient/outpatient status, severity of dysphagia, aspiration symptoms, follow-up interval of VFSS, and current swallowing therapy status were assessed. For non-compliers, reasons for not using thickeners were investigated by telephone interview.Results Among 62 patients, 35 (56.5%) were compliers, and 27 (43.5%) were noncompliers. Eighteen (90%) of 20 inpatients had followed previous recommendations; however, only 17 (40.5%) of 42 outpatients had been using thickeners. Of patient characteristics, only admission status was significantly correlated with compliance. When asked about the reason why they had not used thickeners, noncompliers complained about dissatisfaction with texture and taste, greater difficulty in swallowing, and inconvenience of preparing meals.Conclusion Among Korean dysphagic patients, compliance with a viscosity-modified liquid diet was only about 50%. Betterments of texture and taste along with patient education might be necessary to improve compliance with thickener use.

박지홍,오병모,민유선,방문석,한태륜 대한뇌신경재활학회 2016 뇌신경재활 Vol.9 No.1

Objective: To measure the intra- and inter-rater reliability of a simple sensorimotor performance test for rats, and to evaluate the learning efficiency of a novice rater for the test. Method: Middle cerebral arteries were occluded by intraluminal sutures in 25 male Sprague-Dawley rats (10∼12 weeks old). The sensorimotor performance test was performed by a novice and an experienced rater, with each rater performing the test twice each week for 3 consecutive weeks. A ten-minute standardized video about the rating method was shown to the novice rater after the second test each week. Results: The intra- and inter-rater agreement was determined using Cohen's weighted kappa coefficient. The intra-rater reliability was initially poor for the novice (κ [95% confidence interval], 0.31[−0.02, 0.64]), but it improved significantly after 3-week self education using the standardized video (0.81 [0.69, 0.93], showing almost perfect agreement. The reliability of the experienced researcher was good at all times (κ=0.64, 0.76, 0.71, for week 1, 2, 3, respectively), indicating substantial agreement. The inter-rater reliability showed clear improvement after self-education (κ= 0.44, 0.69, 0.69, for week 1, 2, 3, respectively). Although the total sum score was highly reliable, some of the individual items showed lower intra-and inter-rater agreement. However, each rater showed greater within-rater variability for different subtests. Conclusion: The simple sensorimotor performance test showed high degree of intra- and inter-rater agreement when performed by experienced or properly educated raters. The inaccuracy of the novice was rectified by 3-week self-education using a video.

저산소성 허혈성 뇌손상 후 재활치료

이자호,오병모 대한뇌신경재활학회 2014 뇌신경재활 Vol.7 No.1

The number of survivors after hypoxic-ischemic encephalopathy has been increasing due to recent progressin medical system and care. Impairment after injury ranges from mild memory deficit to vegetative stateor death. Cognitive impairment is particularly common in the survivors, because the hippocampus andmedial temporal lobe are vulnerable to ischemic insult. Medication and cognitive rehabilitation shouldbe initiated to minimize the impact of various cognitive deficits. Instead of Glasgow-Pittsburgh CerebralPerformance Categories, which is insensitive to functional change, standardized functional assessmenttools should also be used in research as well as in rehabilitation settings.

이승학,오병모,천성민,이정찬,민유선,방상흠,김희찬,한태륜 대한재활의학회 2013 Annals of Rehabilitation Medicine Vol.37 No.3

Objective To evaluate the accuracy of the swallowing kinematic analysis.Methods To evaluate the accuracy at various velocities of movement, we developed an instrumental model of linear and rotational movement, representing the physiologic movement of the hyoid and epiglottis, respectively. A still image of 8 objects was also used for measuring the length of the objects as a basic screening, and 18 movie files of the instrumental model, taken from videofluoroscopy with different velocities. The images and movie files were digitized and analyzed by an experienced examiner, who was blinded to the study.Results The Pearson correlation coefficients between the measured and instrumental reference values were over 0.99 (p<0.001) for all of the analyses. Bland-Altman plots showed narrow ranges of the 95% confidence interval of agreement between the measured and reference values as follows: 0.14 to 0.94 mm for distances in a still image, -0.14 to 1.09 mm/s for linear velocities, and -1.02 to 3.81 degree/s for angular velocities.Conclusion Our findings demonstrate that the distance and velocity measurements obtained by swallowing kinematic analysis are highly valid in a wide range of movement velocity.

Objective: To investigate the effects of short-term robot-assisted upper limb training on hemiplegicpatients compared to conventional physical therapy. Method: This study was a prospective, single-blinded, randomized controlled trial. Eighteen hemiplegicpatients due to brain lesions were randomly assigned to: (1) robot-assisted upper limb training andconventional upper limb physical therapy for 30 min a day, respectively (Robot group); or (2) conventionalupper limb physical therapy for 30 min twice a day (Conventional group). All interventions were providedfor 2 weeks, 5 times a week. Each patient was evaluated at pre- and post-treatment by the Fugl-Meyerassessment-upper extremity (FMA-UE), Jebsen hand function test (JHFT), grip power, modified Barthelindex-upper extremity (MBI-UE), line bisection test, and Albert test. Results: The Robot group showed significant improvement in FMA-UE (pre: 13.22 ± 14.20, post: 21.67± 15.84; p = 0.018), MBI-UE (pre: 14.33 ± 7.42, post: 16.56 ± 6.95; p = 0.041), and line bisectiontest (pre: 25.15 ± 34.48, post: 14.93 ± 28.38; p = 0.043). The Conventional group showed significantimprovement only in MBI-UE (pre: 9.22 ± 6.06, post: 15.56 ± 6.19; p = 0.008). The improvementin MBI-UE was larger in the Conventional group than Robot group (6.33 ± 3.28 vs. 2.22 ± 2.49; p= 0.014). Conclusion: This study suggests that short-term robot-assisted upper limb training may improve upperlimb function in hemiplegic patients. However, proper physical therapy may be needed to transferimproved upper limb function to activity of daily living. In addition, goal-directed reaching tasks usinga robot are expected to be a treatment option for hemineglect.
