Background: Pillar pain may develop after carpal tunnel release surgery (CTRS). This prospective double-blinded randomized trial investigated the effectiveness of extracorporeal shock wave therapy (ESWT) in pillar pain relief and hand function improvement. Methods: The sample consisted of 60 patients with post-CTRS pillar pain, randomized into two groups. The ESWT group (experimental) received three sessions of ESWT, while the control group received three sessions of sham ESWT, one session per week. Participants were evaluated before treatment, and three weeks, three months, and six months after treatment. The pain was assessed using the visual analogue scale (VAS). Hand functions were assessed using the Michigan hand outcomes questionnaire (MHQ). Results: The ESWT group showed significant improvement in VAS and MHQ scores after treatment at all time points compared to the control group (P < 0.001). Before treatment, the ESWT and control groups had a VAS score of 6.8 ± 1.3 and 6.7 ± 1.0, respectively. Three weeks after treatment, they had a VAS score of 2.8 ± 1.1 and 6.1 ± 1.0, respectively. Six months after treatment, the VAS score was reduced to 1.9 ± 0.9 and 5.1 ± 1.0, respectively. The ESWT group had a MHQ score of 54.4 ± 7.7 before treatment and 73.3 ± 6.8 six months after. The control group had a MHQ score of 54.2 ± 7.1 before treatment and 57.8 ± 4.4 six months after. Conclusions: ESWT is an effective and a safe non-invasive treatment option for pain management and hand functionality in pillar pain.

Purpose: This study examined the effects of a spiral elastic band for the walking function on patients with chronic stroke. Methods: Twenty one chronic stroke patients were recruited and divided randomly into the experimental group and control group. Both groups performed mat exercises and gait training three times a week for four weeks, and gait training was applied to the experimental group with additional spinal elastic bands. Results: The results of this research were as follows. The 10MWT measurements showed that the velocities within and between the groups decreased significantly, and the results of TUG showed significant decreases in velocities after the interventions in both the control group and experimental group. On the other hand, there were no significant differences between the control and experimental group. The FRT measurements showed significantly increased stride lengths within and between the groups. The measurements of the stride length, stride velocity, cadence, and step length showed significant improvement within the groups, but there was no significant difference between the groups. The measurement of stance showed that the non-paralytic patients had a significant increase in the rates within the groups and a significant difference was observed between the groups. Conclusion: Spiral elastic bands are an effective intervention method for rehabilitation programs to enhance the walking function in the clinical field. A treatment needs to be developed for patients with walking problems due to various disorders by investigating the action mechanism of spiral elastic bands.

Objective : The purpose of this study was to identify the effect of crafts and handwriting on bilateral coordination during task performance. Methods : Randomly selected 30 college students without hand disability were invited for the study, and grouped 3(test group 1 for crafts, test group 2 for handwriting, and control group) with 10 students per group respectively. Then Jebsen-taylor hand function test, Purdue pegboard test, and Minnesota manual dexterity test were employed for evaluating changes before and after the intervention. Results : After training intervention of crafts and handwriting for two test groups, test groups showed better bilateral coordination significantly than the control group. Especially test group 1(crafts) showed a bigger difference at Jebsen-taylor hand function test, and likely test group 2(handwriting) did at Purdue pegboard test. Conclusion : It was found that crafts increase bilateral coordination, while handwriting increase hand dexterity during task performance. That is, crafts and handwriting affect tasks differently. Further studies applying various crafts and handwriting for many age groups will be helpful for identifying the better way of occupational intervention for individuals in lack of bilateral coordination.

The limited walking ability after a stroke restricts a patient's independent mobility at home and in the community. It also brings about significant social handicaps. Therefore, it is necessary to improve walking ability in community-dwelling persons with stroke. The purpose of this study was to evaluate the effectiveness of gait training and muscle strengthening exercise of lower extremities in persons with chronic stroke. Nineteen community-dwelling individuals with stroke participated in this program. The exercise program lasted for seven weeks, with a 1-hour program twice per week, and it consisted of balance training, gait training, and strengthening of lower extremities. The outcome of the program was assessed by the gait speed, Wisconsin Gait Scale (WGS), Berg Balance Scale (BBS), and Stroke Impact Scale (SIS). Significant effects were found for the WGS, BBS, and mobility and hand function domain of the SIS (p<.05). It was found that short-term gait training exercise could improve quality of gait, balance, and mobility. Therefore, a more effective exercise program is required for community-based persons with stroke.

The neural networks are a famous model to learn the nonlinear function or nonlinear system. The main point of neural network is that the difference actual output from desired output is used to update weights. Usually, the gradient descent method is used for the learning process. On training process, if learning rate is too large, neural networks hardly guarantee convergence of neural networks. On the other hand, if learning rate is too small, the training spends much time. Therefore, one major problem in use of neural networks are to decrease the teaming time while neural networks are guaranteed convergence. In this paper, we suggest the model of fuzzy logic to neural networks to calibrate learning rate. This method is to tune learning rate dynamically according to error and demonstrates the optimization of training.

The aim of this study was to investigate the effects of virtual reality training on upper extremity function and activities of daily living in patients with sub-acute stroke. The present study enrolled 18 patients with sub-acute stroke. All subjects were assigned into either the experimental group (n=9) or control group (n=9). Both groups received conventional occupational therapy for 30 minutes/day, 5 times a week, for 4 weeks. Additionally, the experimental group performed virtual reality training in each session for 30 minutes/day, and the control group conducted conventional occupational therapy in each session for 30 minutes/day. The outcome measures were performed through the Fugl-Meyer Assessment (FMA) and the Korean-modified Barthel Index (K-MBI) before and after intervention. In results, the experimental group showed significant improvements in the scores of FMA and K-MBI after intervention (p<.05). The control group showed significant improvements in the shoulder/elbow/forearm, wrist, and hand sub-domains of the FMA and K-MBI (p<.05). After intervention, the experimental group showed significantly greater improvements in the total score and in the wrist and hand sub-domains of the FMA than control group (p<.05). These findings suggest that virtual reality training may have positive effects on the improvements of upper extremity function in patients with sub-acute stroke.

Objective: The purpose of this study was to investigate the effects of vibration resistance exercise (VRE) in patients with tennis elbow on strength, range of motion (ROM), function, pain and quality of life (QOL). Design: Randomized controlled trial. Methods: Twenty-seven participants were randomly assigned to either the VRE group (n=9), weight resistance exercise (WRE) group (n=9) or control group (n=9). Each group underwent hot compress for 15 minutes and electrotherapy for 15 minutes. The VRE group underwent exercises using a vibrating ball for 5 minutes. The WRE group underwent exercises using dumbbells for 5 minutes. All participants were evaluated on wrist extension strength using a hand-held dynamometer, grip strength level through an electric dynamometer, and ROM through a smartphone goniometer application before and after intervention. Patient-rated tennis elbow evaluation, Visual Analogue Scale and Short Form 8 were measured by questionnaires. Results: There were showed significant differences among the VRE, WRE and control group in wrist extensor muscle and hand grip strength, ROM, elbow function, pain and QOL after intervention (p<0.05). The VRE group showed a greater significant improvement in wrist extensor muscle strength and elbow function compared with the others (p<0.05). The VRE and the WRE groups had a more significant improvement in wrist extensor muscle and hand grip strength, ROM and pain compared with the control group (p<0.05). However, there were no significant differences in QOL among the three groups. Conclusions: Combining VRE with thermotherapy and electrotherapy appears to be more effective in improving wrist extension strength, ROM, elbow function, QOL in tennis elbow patients.

The aim of this study is evaluate the effect of a cognitive occupational therapy program on cognitive function, depression and hands function for patients with dementia living in a local community. A cognitive rehabilitation program of 10 weeks focusing on the occupational therapy is conducted from September to December 2012 on 21 patents (experimental group: 12, control group: 9) with dementia who are admitted to nursing homes in a metropolitan region. In the experimental group, the cognitive function, depression level, hand strength, and hand coordination ability is significantly improved after the application of the cognitive program (p<.05). In conclusion, the cognitive occupational therapy program may be a useful intervention for dementia. Because the therapeutic goal for dementia treatment is mainly concentrated on the amelioration of dementia symptoms, thus it is necessary to develop a various cognition training program that can be maintained the patient's residual functional capacity and returned to the social community through the early detection and the early intervention.
