Purpose: This study sought to identify the effects of an insole applied for the flexible flat-foot condition on dynamic balance and ankle muscle activities during the Y-balance test (YBT). Methods: Thirteen flexible flat-footed adults and an equal number of normal-footed adults were enrolled. The dynamic balance of the subjects was measured using the YBT, which is a reach test. While they were reaching forward with their foot, the percentage maximum voluntary isometric contraction (MVIC) of the tibialis anterior, peroneus longus and medial and lateral gastrocnemius were measured and analyzed. The flat-footed group then applied the ready-made insoles and underwent the YBT again. A comparison of the distance and muscle activity was conducted using YBT, not only between the flat-footed and control group, but also between the flat-footed group before and after the application of the insole. Results: Between the groups, the anterior reach distance in the flat-footed group was significantly lower, but there were no significant differences observed in the posteromedial and posterolateral directions. With the insole, the reach distance of the flat-footed group was significantly increased in the anterior and posterolateral direction compared to the control group. With the insole, the lateral gastrocnemius activity significantly decreased compared to trials without the insole in the flat-footed group, but there were no significant differences in the other muscles. Conclusion: The insole for flat-footed subjects can maintain the medial arch of the foot, and it may help enhance functional and mechanical dynamic balance in people with flat feet.

Background and Objectives: In masking level difference (MLD), the masked detection threshold for a signal is determined as a function of the relative interaural differences between the signal and the masker. Study 1 analyzed the results of school-aged children with good school performance in the MLD test, and study 2 compared their results with those of a group of children with poor academic performance. Subjects and Methods: Study 1 was conducted with 47 school-aged children with good academic performance (GI) and study 2 was carried out with 32 school-aged children with poor academic performance (GII). The inclusion criteria adopted for both studies were hearing thresholds within normal limits in basic audiological evaluation. Study 1 also considered normal performance in the central auditory processing test battery and absence of auditory complaints and/or of attention, language or speech issues. The MLD test was administered with a pure pulsatile tone of 500 Hz, in a binaural mode and intensity of 50 dBSL, using a CD player and audiometer. Results: In study 1, no significant correlation was observed, considering the influence of the variables age and sex in relation to the results obtained in homophase (SoNo), antiphase (SπNo) and MLD threshold conditions. The final mean MLD threshold was 13.66 dB. In study 2, the variables did not influence the test performance either. There was a significant difference between test results in SπNo conditions of the two groups, while no differences were found both in SoNo conditions and the final result of MLD. Conclusions: In study 1, the cut-off criterion of school-aged children in the MLD test was 9.3 dB. The variables (sex and age) did not interfere with the MLD results. In study 2, school performance did not differ in the MLD results. GII group showed inferior results than GI group, only in SπNo condition.

Objectives: The purpose of this study is to evaluate anti-breast cancer and anti-inflammatory effects of Chungganhaewool-tang and Shipyeukmiyeugi-eum. Methods: MDA-MB-231 cells were used to measure cytotoxicity, Reactive oxygen species (ROS) production, protein expression amounts of Bcl-2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xl), Cytochrome C Caspase-3, Caspase-7, Caspase-9, Poly ADP-ribose polymerase (PARP), Nuclear factor erythroid-2-related factor 2 (Nrf2), Heme oxygenase-1 (HO-1) and NAD (P) H Quinone Oxidoreductase 1 (NQO1) to evaluate the anti-breast cancer effects of Chungganhaewool-tang (CHT) and Shipyeukmiyeugi-eum (SYE), and THP-1 cells, differentiated into macrophage and induced inflammation with Lipopolysaccharide (LPS), were used to measure production amounts of ROS, Nitric oxide (NO), and protein expression amounts of Inducible nitric oxide synthase (iNOS), Cyclooxygenase (COX-2), Interleukin-1 beta (IL-1β), Interleukin-6 (IL-6) and Tumor necrosis factor-alpha (TNF-α) to evaluate the anti-inflammatory effects of CHT and SYE. Results: CHT and SYE reduced MDA-MB-231 cell counts, increased protein expression of Bax and Cytochrome C, and decreased protein expression of Bcl-2, Bcl-xl. The protein expression amounts of Caspase-3, 7, and 9 decreased, but amounts of the active form, cleaved Caspase-3, 7, and 9, increased. In addition, PARP protein expression decreased, the amount of PARP protein in the cleaved form increased, and the amount of protein expressions of Nrf2 and HO-1 decreased, but NQO1 showed no significant difference. In THP-1 cells CHT and SYE reduced ROS and NO, and reduced protein expressions of iNOS, COX-2, IL-1, and TNF-α, but only SYE groups reduced IL-6. Conclusions: This study suggests that CHT and SYE have potential to be used as treatments for breast cancer.

PURPOSE: The present research examined the effects of progressive robot-assisted step training on the strength of the lower extremity and gait speed of an individual with stroke through changes between the baseline and the intervention stage (1, 3, 6, 9, and 12 months). METHODS: A single-subject (A-B) design was performed for a chronic stroke patient aged 70 years old. The robot-assisted step training was conducted three times a week during 12 months (40 minutes/session), and the assessment was conducted a total of seven times between the baseline and the intervention (No. 1, 3, 6, 9, and 12 months) to determine the effect of the intervention. RESULTS: As a result of the intervention, the muscle strength at the lower extremity of the paralysis side increased by the greatest extent 12 months after the intervention compared to the baseline, and the gait speed via the 10-meter walk test was increased as well. CONCLUSION: Long-term robot-assisted step training might be an effective intervention for improving the strength of the paretic lower extremity muscles and gait speed in stroke patients with difficulty walking independently. Further studies with sufficient sample sizes and a randomized control group will be needed to evaluate the long-term effects of robotic stepping rehabilitation.

Objectives : The purpose of this study is to retrospectively analyze 3 years of inpatient dermatologic and surgical consultation to Korean medicine ophthalmology, otolaryngology & dermatology department in Korean medicine hospital. Methods : We classified dermatological and surgical inpatient consultations between September 1st, 2019 and August 31st, 2022, based on electronic medical record by gender, age, hospitalized department, categories of diseases. Results : Total number of consultations were 336. The proportion of female and male were 2.5:1, and the average of age was 65.6 and 60, respectively. The most frequently referred skin disease category was infectious skin disease(39.9%), followed by eczema(20.2%), dermatoses due to physical forces(10.1%), pigment anomalies(7.1%), nevi and tumors(4.8%), diseases of the skin appendages(4.2%), urticaria(3.9%), and others(4.9%). Consultations from department of Korean rehabilitation medicine, and Korean internal medicine were most common, because they have a comparatively large number of inpatients and long hospitalization period. In case of infectious disease and skin ulcer, patients from Korean internal medicine were frequently consulted due to characteristics of stroke and internal diseases. Conclusions : This study identified the frequency of consultation and the disease group with many requests for each department. Identifying the characteristics of diseases with a high frequency of consultation will prevent various dermatological problems that may occur by department. In addition, it was found that a prompt consultation was needed for accurate diagnosis and treatment in dermatological problem.

It is known that chronic pain and injury of upper limb joint tissue in manual wheelchair users is usually caused by muscle imbalance, and the propulsion speed is reported to increase this muscle imbalance. In this study, kinematic variables, electromyography, and ultrasonographic images of the upper limb were measured and analyzed at two different propulsion speeds to provide a quantitative basis for the risk of upper extremity joint injury. Eleven patients with spinal cord injury for the experimental group (G_E) and 27 healthy adults for the control group (G_C) participated in this study. Joint angles and electromyography were measured while subjects performed self-selected comfortable and fast-speed wheelchair propulsion. Ultrasound images were recorded before and after each propulsion task to measure the acromiohumeral distance (AHD). The range of motion of the shoulder (14.35 deg in G_E; 20.24 deg in G_C) and elbow (5.25 deg in G_E; 2.57 deg in G_C) joints were significantly decreased (p<0.001). Muscle activation levels of the anterior deltoid, posterior deltoid, biceps brachii, and triceps brachii increased at fast propulsion. Specifically, triceps brachii showed a significant increase in muscle activation at fast propulsion. AHD decreased at fast propulsion. Moreover, the AHD of G_E was already narrowed by about 60% compared to the G_C from the pre-tests. Increased load on wheelchair propulsion, such as fast propulsion, is considered to cause upper limb joint impingement and soft tissue injury due to overuse of the extensor muscles in a narrow joint space. It is expected that the results of this study can be a quantitative and objective basis for training and rehabilitation for manual wheelchair users to prevent joint pain and damage.

Purpose: We investigated the effects of multimodal vs. stabilization exercises on chronic low back pain. Methods: Study participants were randomly assigned to a multimodal exercise (n = 20) or a stabilization exercise group (n = 20). Participants in the multimodal exercise group performed stabilization, stretching, and endurance exercises, whereas those in the stabilization exercise group performed only stabilization exercises. Participants in both groups performed the exercises for 1 hour thrice a week for 5 weeks. The following outcomes were evaluated: pain intensity (numeric rating scale), disability (the Oswestry Disability Index [ODI] and the Roland-Morris Disability Questionnaire [RMDQ]), pain-induced fear (the Fear of Daily Activities Questionnaire [FDAQ], the Fear-Avoidance Belief Questionnaire [FABQ], and the Tampa scale for kinesiophobia-11 [TSK-11]). Outcome measures were evaluated at baseline and after intervention. Results: Significant post-intervention improvement was observed in pain intensity and the RMDQ and FDAQ scores in both groups (p < 0.01). The post-intervention ODI, FABQ, and TSK-11 scores were improved in the multimodal exercise group (p < 0.01). Additionally, significant differences were observed in pain intensity, as well as in the ODI, FDAQ, and FABQ scores in the multimodal exercise group compared with these findings in the stabilization exercise group (p < 0.01). Conclusion: The multimodal and stabilization exercise programs reduced pain intensity, disability, and pain-induced fear. Compared with stabilization exercises, multimodal exercises more effectively reduced pain intensity, disability, and pain-induced fear. This study highlights that musculoskeletal rehabilitation for people with chronic low back pain should include a multimodal exercise program.
