The purpose of this study was to investigate the effects of occupation-based bilateral upper extremity training and transcranial direct current stimulation on upper limb function in stroke patients. The study group was divided into 13 experimental groups with occupation-based bilateral upper extremity training and transcranial direct current stimulation, and 13 controls with only occupation-based bilateral upper extremity training. A total of 4 weeks, 50 minutes, 5 times a week conducted, the patients were tested with Canadian Occupational Performance Measure(COPM), Accelerometer, Fugle-Meyer Assessment(FMA), and Motor Activity Log(MAL). As a result of the study, the experimental group and the control group showed significant improvement in both occupation satisfaction and performance, usage of the affected side and the tendon side, recovery of upper limb function, and quality of movement, In particular, the experimental group showed a significant difference in the amount of the affected side than the control group. Therefore, it was found that the combination of occupation-based bilateral upper extremity training and transcranial direct current stimulation had a positive effect on the recovery of upper limb function in stroke patients.

Background: Stroke patients usually have arm weakness, which affects trunks and arms. Objective: To investigate the effects of paretic side and non-paretic side arm training on trunk control and upper limb functions. Design: Randomized Controlled Trial (single blind). Methods: Twenty patients with stroke in hospital were enrolled in the study. Twenty subjects were randomly assigned to paretic side arm training group (PATG, n = 10) or non-paretic side arm training group (NATG, n = 10). Trunk impairment scale (TIS) was used for trunk control, and box and block test (BBT) was used for upper limb function. Training was conducted for 4 weeks. Results: PATG showed significant difference in TIS (static balance, dynamic balance, coordination, total score) and BBT. NATG showed significant differences in static balance, and dynamic balance and total score except for coordination and BBT. PATG also showed a more significant difference in BBT and coordination and total score than NATG. Conclusions: The arm training performed on the paretic side are more effective than those performed on the non-paretic side in improving both upper limb function and trunk control in stroke patients.

Constraint-Induced Movement Therapy(CIMT) is considered as one of the most interesting upper extremity rehabilitation in the field of neurorehabilitation. CIMT is an intensive training provided in the affected upper limb for 6 hours a day, 5 days a week for 2 weeks, while unaffected arm is restrained for 90% of waking hours. Recently, instead of CIMT, modified Constraint-Induced Movement Therapy(mCIMT) has been applied because of the clinical limitations of CIMT. CIMT or mCIMT studies have used various outcome instruments to measure different aspects of upper limb function after intervention. There are various kinds of evaluation tools to measure different aspects of upper limb function after CIMT intervention. It has been proven that Pediatric Motor Activity Log(PMAL), Quality of Upper Extremities Skills Test(QUEST), Melbourne Assessment of Unilateral Upper Limb Function(MAULF), Assisting Hand Assessment (AHA) are effective. The purpose of this study was to investigate the cortical change in children with hemiplegic cerebral palsy after CIMT. As a result, use-dependent cortical reorganization was revealed. Also, increased activity of the contralateral motor cortex and decreased activity of the ipsilateral cortex were found. It supports the mechanism of cortical reorganization, the principles of neural plasticity and specifically activation of the contralateral cortex, for improving upper limb function after CIMT.

Purpose : In this study, we applied a computerized cognitive rehabilitation program (CoTras-C) for children with cerebral palsy. Research was conducted to investigate the impact of upper limb function, sensory function, and activities of daily living. Methods : The study period lasted 10 weeks from October 2019 to December 2019. The study subjects were 12 subjects according to the selection criteria, and a computerized cognitive rehabilitation program (CoTras-C) was conducted twice a week for 30 minutes before and after the application of basic occupational therapy. Results : As a result of the computerized cognitive rehabilitation program, scores of upper limb function (QUEST), sensory function (SSP-2), and daily life activity (WeeFIM) were significantly improved (p>.05). From the result of examining the motor area, improvement in fine-motor function and protective extension through touch pad or controller operation was found. It also showed improvement in activities of daily living including motor and activities of daily living including social cognition. In the sensory function evaluation, it was not significant in movement sensitivity. Significant differences were shown in the items excluding olfactory/taste sensitivity. Conclusion : The application of the computerized cognitive rehabilitation program (CoTras-C) showed significant results in upper limb function, sensory function, and daily life activities of children with brain lesions. Based on these results, future studies need to generalize the study by expanding the age or population of children with brain lesions, or by expanding the diversity of diseases and environments.

This study was conducted to investigate the effects of therapeutic climbing training on upper limb function and quality of life of stroke patients and to suggest possibilities for clinical intervention. This study investigated 14 stroke patients who were assigned to either a treatment climbing training group or a control group (n=7 each). The experimental groups performed general physical therapy and occupational therapy. In addition, therapeutic climbing training using the Potsdam model was conducted for 30 minutes three times a week for 6 weeks. The control group performed general physical therapy and occupational therapy. A manual function test was used to evaluate upper limb function, and a short form 36-item questionnaire was used to evaluate quality of life. The results showed that there was a significant difference in upper limb function of the experimental group according to time (p<0.05). There was also a significant difference in the quality of life according to time in the experimental group, and a significant difference in quality of life between the experimental group and the control group (p<0.05). Therapeutic climbing training by stroke patients positively affected quality of life by increasing the SF-36 scores and upper limb function. Taken together, these findings confirmed that training using therapeutic climbing is valuable for rehabilitation and clinical intervention of stroke patients.

Objectives: This study investigated musculoskeletal symptoms in upper limbs according to the working environment (job stress) of dental hygienists and examine their relationship with upper limb functions. Methods: The subjects include 198 dental hygienists in dental hospitals and dental clinics in Pusan and Gyeongnam. The questionnaire was consisted of general characteristics of the subjects, job stress, musculoskeletal symptoms in upper limbs and function (Disability Measurement Tool for Upper Extremity Disorders-11, DASH-11). Results: The study was analyzed their musculoskeletal symptoms in upper limbs according to their general characteristics and found that the symptoms occurred in the neck (39.4%), the shoulders (54.6%), elbows (14.7%), and the hands (50.0%). Job stress was associated with upper limb functions (DASH-11) (model 3, B=5.210, p=0.012) and repeated elbow bending and spreading posture was associated with DASH-11 (model 3, B=6.561, p=0.029). Elbow symptoms were associated with DASH-11 in the upper limbs (B=10.679, p=0.003). Conclusion: Dental hygienists are experiencing limitations of upper limb function due to job stress. In particular, even if the correction of their uncomfortable posture is significantly related to the job stress and upper limb function, in order to improve the upper limb function of the dental hygienist, efforts to reduce the job stress as well as the uncomfortable posture are necessary.

This paper proposes a novel intelligent wheelchair vehicle system that enables upper limb exercises, lower limb standing exercises and rehabilitation training in a daily life. The proposed system, which can be used to prevent at least the degeneration of body movements and further atrophy of musculoskeletal system functions, considers the characteristics and mobility of the old and the disabled. Its main purpose is to help the old and the disabled perform their daily activities as much as they can, minimizing the extent of secondary disabilities. In other words, the system will provide the old and the disabled with regular and quantitative rehabilitation exercises and diagnosis using the wheelchair-based upper/lower limb rehabilitation vehicle system and then verify their effectiveness. The system comprises an electric wheelchair, a biometric module to identify individual characteristics, and an upper/lower limb rehabilitation vehicle. In this paper the design and configuration of the developed vehicle is described, and its operation method is presented. Moreover, to verify the tracking performance of the proposed system, dangerous situations according to biosignal changes occurring during the rehabilitation exercise of a non-disabled examinee are analyzed and the performance of the upper/lower limb rehabilitation exercise function depending on muscle strength is evaluated through a neural network algorithm.

The requirement of rehabilitation is increasing from the stroke, spinal cord injury. One of the most difficult part is the upper limb rehabilitation because of its nervous complexity. A rehabilitation has effectiveness when a professional therapist treats in work at facility, but it has problems of an accessibility, a constant availability, a self-participation and taking lots of cost and time. In this paper, we test and experiment the accuracy and execution time of the pattern recognition algorithms like PCA, ICA, LDA, SVM to show the recognition possibility of it on the upper limb function from the 3D trajectory information which is gathered from stereo vision sensor(Kinect). From the result, PCA, ICA have low accuracy, but LDA, SVM have good accuracy to use for physical rehabilitation on the upper limb function.

Objective : This systematic review aimed to investigate the impact of transcranial direct current stimulation combined with constraint-induced movement therapy (CIMT) in patients with stroke Methods : PubMed and NDSL databases were employed to review literature published between January 2009 and December 2018. The main search terms were "Transcranial direct current stimulation" or "tDCS," "Constraint-induced movement therapy" or "CIMT," "Upper extremity function," "Upper limb," and "Stroke." Based on the inclusion and exclusion criteria, 6 articles were selected. Furthermore, intervention effects on upper extremity function, activities of daily living, and cortical activity were assessed. Results : The current intensity, application time, and protocol of the CIMT varied the between studies. However, the intervention procedures to perform CIMT immediately after transcranial direct current stimulation was the same. Transcranial direct current stimulation combined with CIMT was effective in improving upper limb function and activities of daily living in patients with stoke and had a significant effect on cerebral cortex activation. Conclusions : This study provides information on transcranial direct current stimulation combined with CIMT for use by clinical therapists. Further studies are needed to standardize the stimulation time, current intensity, and electrode attachment position. Furthermore, randomized controlled trials, including long-term follow up, are needed for larger populations using the most appropriate CIMT protocol.
