Purpose: This study aimed to assess the effectiveness of gait training with the use of an electromechanical gait trainer with functional electrical stimulation (FES) for patients that had undergone subacute stroke. Methods: The study subjects included nine subacute stroke patients of the Korea National Rehabilitation Center in Seoul, Korea. Outcome was measured using the timed Up and Go test, Fugl-Meyer-L/E assesment, with determination of the comfortable maximal gait speed, composite spasticity score, functional ambulatory category and Berg balance scale. All measured scores were recorded before, during, and after rehabilitation and at an eight-week follow-up. Results: Patients who received electromechanical-assisted gait training in combination with FES after subacute stroke were more likely to achieve independent walking, functional activities, balance and gait speed. Conclusion: The outcome of our gait-training program demonstrates that it may be practical to integrate FES into electromechanical gait training without any adverse effects. However, further randomized controlled studies are needed to evaluate if patient outcome after combined training is superior to outcome after the use of electromechanical gait trainer treatment alone or conventional gait training alone.

PURPOSE: Examine the effects of auditory feedback and functional electrical stimulation on balance, walking ability, and lower extremity function of subacute stroke patients. METHODS: Twenty-seven subjects diagnosed with subacute stroke within six months were randomly divided into three groups: test group 1, which performed walking exercises with auditory feedback and functional electrical stimulation; test group 2, which performed walking exercises only with functional electrical stimulation; control group applied only functional electrical stimulation, with nine subjects each. RESULTS: There were significant pre- to post-intervention differences in BBS in the gait training group with auditory feedback and functional electrical stimulation treatment, and significant pre- to post-intervention differences in BBS, sit-to-stand time, and average step speed in the gait training group with functional electrical stimulation, but no statistically significant differences in between-group comparisons. CONCLUSION: Gait training with auditory feedback and functional electrical stimulation can improve the balance and gait performance in stroke patients. Therefore, in the future, gait training with auditory feedback and functional electrical stimulation therapy may be suggested as a gait rehabilitation training tool for stroke patients.

Objectives : To evaluate the evidence supporting the effectiveness of Chuna manual therapy for functional dyspepsia. Methods : We conducted search across the 3 electronic databases (Pubmed, CAJ and Oasis) to find all of randomized controlled clinical trials(RCTs) that used Chuna manual therapy as a treatment for functional dyspepsia. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results : Thirteen RCTs met our inclusion criteria. The meta-analysis showed positive results for the use of Chuna manual therapy combined with medication treatments in terms of the efficacy rate when compared to medication treatments alone. Positive results were also obtained, in terms of the efficacy rate, when comparing Chuna manual therapy combined with medication plus specific electromagnetic therapy to medication treatments alone. Conclusions : Our systematic review found encouraging but limited evidence of Chuna manual therapy for functional dyspepsia. However, to obtain stronger evidence without the drawbacks of trial design and the quality of studies, we recommend sham-controlled RCTs or comparative effectiveness research to test the effectiveness of Chuna manual therapy.

Stroke is a major cause of death and long-term disability. Because muscle weakness is one of the most prominent consequences of stroke, it was considered important to determine whether exercise in order to improve muscle strength and range of motion could have an effect in limiting the learned disuse of the affected side. The purpose of the study was to identify the effects of an 8 week rehabilitation program on physical and cognitive ability in stroke patients. A total of 18 patients who were admitted to the oriental medicine unit of a K medical center in Seoul were recruited : ten for the experimental group and eight for the control group. The rehabilitation program consisted of three level's of active and passive exercises for prevention of muscle contracture and at range of motion. Muscle strength, flexibility of the upper and lower extremity, perceived balance, functional independence, depression, and quality of life for the two groups were compared at the pretest and 4 and 8 weeks after the rehabilitation program. The results are as follows : 1) When measuring muscle strengths of shoulder abduction and elbow flexion, hip flexion and knee extensor, ankle dorsi-flexor and muscle strength of knee flexor. Muscle strength of knee flexor for the experimental group was significantly higher than the comparison group at the 4 weeks. 2) Muscle strength and flexibility of the ankle dorsi -flexor for the experimental group was significantly better than for the control group at 8 weeks. 3) Functional independence, perceived balance, and Tinetti balance for the experimental group as measured at 4 and 8 weeks were better than for the control group. Also, there were changes over time in physical balance and functional ability, but there was no significant differences between the groups. 4) The experimental group showed a higher quality of life and lower depression than the control group at 8 weeks. 5) Muscle strength and flexibility of ankle dorsi -flexor were significantly changed over time and an interaction between group and time. The findings suggested that the rehabilitation program would improve the physical and psychological status of the stroke patients. Thus, the gains in actual or perceived ability to perform physical activities was marked.

Purpose : This article reviewed the advances in the understanding of the effect of motor rehabilitation and brain plasticity on functional recovery after CNS damage. Methods : This is literature study with Pubmed, Medline and Science journal. Results : The inability of CNS neurons to regenerate is largely associated with nonneuronal aspects of the CNS environment. Especially, this neuronal growth inhibition is mediated by myelin associated glycoprotein, olygodendrocyte-myelin glycoprotein, and NOGO. Enriched environment, motor learning, forced limb use have been utilized in scientific studies to promote functional reorganization and brain plasticity. Especially, enriched environment and motor enrichment may prime the brain to respond more adaptively to injury, in part by expressed neurotrophic factors. Conclusions : These reviews suggest that activity-induced neural plasticity occur in damaged brain areas in order to functional reorganization, where it could contribute to motor recovery, and represent a target for stroke rehabilitation.

Two patients, diagnosed as cervical spinal cord injury, were hospitalized and treated by Korean medical interventions with Functional Electrical Stimulation (FES). The range of motion of the shoulder joint, manual muscle test were adopted to measure the resulting motor recovery after treatment. And the Korean version of Barthel index (K-MBI) was adopted as a method of measuring the improvement of quality of life after treatment. The range of motions and muscle strengths of the shoulder joints were improved. The activities of daily living were slightly improved in case 2, but showed no improvement in case 1. FES was effective for upper extremities rehabilitation of spinal cord injured patients. Further studies are needed to set up an Korean medical protocol for spinal cord injury rehabilitation.

Purpose: Cognitive function is a main concern for rehabilitation progression in individuals who have sustained brain damage, even among those whose motor function has returned after brain damage. The purpose of this study was to investigate how cognitive impairment relates to functional independence in postural stability and gait performance in patients with chronic hemiparetic stroke. Methods: This was an observational design in an outpatient rehabilitation hospital. Twenty-eight adults with chronic hemiparetic stroke, receiving a course in an outpatient rehabilitation program, participated in this study. They were divided into two groups (i.e., non-cognitive impairment and cognitive impairment groups) via a cut-off score of 23 or less on a mini-mental state examination. Functional independence was assessed with the timed up-and-go test (TUG), 10-meter walk test (10mWT), five times sit-to-stand test (FTSST), Berg balance scale (BBS), and modified Barthel index (MBI). The independent t-test was used for statistical analysis when comparing the two groups. Results: The cognitive impairment group had less functional independence, balance, and gait performance than those of the non-cognitive impairment group had. The former also showed a statistically significant decrease in their TUG score, FTSST score, BBS score, and MBI score compared to the latter, but not in their 10mWT score (p<0.05). Although the non-cognitive impairment group walked faster than the cognitive impairment group did, that difference was not statistically significant (p>0.05). Conclusion: The results of this study suggest that cognitive impairment relates to functional independence in postural stability and the activities of daily living. In rehabilitation settings, cognitive impairment would be considered a major component in therapeutic rehabilitation to overcome the patients difficult physical problems and to treat for improving functional independence more after stroke.

Objectives : This review aims to evaluate the effects and the safety of Chuna manual therapy(CMT) for pediatric functional constipation. Methods : We searched 10 electronic databases(Pubmed, EMBASE, Cochrane Library, CAJ, Oasis, RISS, KISS, NDSL, KMBASE, KISTI) and related 2 journals until October 2018. We included randomized controlled trials(RCTs) of testing CMT for pediatric functional constipation. The methodological quality of RCTs related assessed by the Cochrane risk of bias tool. Results : 16 RCTs were eligible in our inclusion criteria. The meta-analysis of 11 studies showed positive for use CMT for pediatric functional constipation. CMT significantly improved total efficancy rate compared with medications (P < 0.00001). Conclusions : There is evidence of CMT for pediatric functional constipation with meta-analysis. However, our systematic review has limited evidence to support CMT for pediatric functional constipation. because the quality of relevant trials is relatively poor. Further well-designed RCTs should be encouraged. the quality of relevant trials is relatively poor.

Objective To evaluate the association between progression of curvature of scoliosis, and correction for functional component in patients with juvenile idiopathic scoliosis (JIS). Methods We retrospectively reviewed medical data of patients prescribed custom molded foot orthosis (FO) to correct inequality of RCSPA (resting calcaneal stance position angle), and chose 52 patients (26 females, 26 males) with Cobb angle ${\geq}10^{\circ}$ in radiology and uneven pelvic level at iliac crest by different RCSPA (${\geq}3^{\circ}$) as a factor of functional scoliosis. They had different hump angle ${\geq}5^{\circ}$ in forward bending test, for idiopathic scoliosis component. Their mean age and mean period of wearing FO were $79.5{\pm}10.6months$ and $18.6{\pm}0.70months$. Results Cobb angle was reduced from $22.03^{\circ}{\pm}4.39^{\circ}$ initially to $18.86^{\circ}{\pm}7.53^{\circ}$ after wearing FO. Pelvis height difference and RCSPA difference, were reduced from $1.07{\pm}0.25cm$ initially to $0.60{\pm}0.36$, and from $4.25^{\circ}{\pm}0.71^{\circ}$ initially to $1.71^{\circ}{\pm}0.75^{\circ}$ (p<0.01). Cobb angle improved most in 9 months. However, there was no significant improvement for those with more than $25^{\circ}$ of Cobb angle initially. Mean Cobb angle improved in all age groups, but patients less than 6 years had clinically significant improvement of more than $5^{\circ}$. Conclusion JIS can have functional components, which should be identified and managed. Foot orthosis is useful in correcting functional factors, in the case of pelvic inequality caused by different RCSPA, for patients with juvenile idiopathic scoliosis.

This paper presents a force control based on the observer without taking any force or torque measurement from the robot which allows realizing more stable and robust human robot interaction for the developed multi-functional upper limb rehabilitation robot. The robot has four functional training modes which can be classified by the human robot interaction types: passive, active, assistive, and resistive mode. The proposed observer consists of internal disturbance observer and external force observer for distinctive performance evaluation. Since four training modes can be quantitatively identified as impedance variation, position-based impedance control with feedback and feedforward controller was applied to the assistive training mode. The results showed that the proposed sensorless observer estimated cleaner and more accurate force compared to the force sensor and the impedance controller embedded with the proposed observer completed the assistive training mode safely and properly.
