Purpose : The purpose of this study was to evaluate the effects of mirror movements(MM) on upper extremity's function and measure the change of MM on stroke patients depending on the elapse of time. Methods : Sixteen stroke patients with MM and Sixteen stroke patients without MM were recruited for this study. Intended movements and MM were measured by two dynanometers of MP150 system(BIOPAC System Inc., Santa Barbara, U.S.A). The upper extremity's motor function was measured using manual function test(MFT), Fugl-Meyer assesment(FMA). Results : The change rates of upper extremity's motor function test showed significant group differences in FMA but not in MFT between the patients with MM and without MM from the first test to the second test. In each group motor function generally more increased. The magnitudes of MM decreased from the first test to the second test. Conclusion : These results indicate that stroke patients with MM have a significant motor deficit. But motor deficit could be recovered by spontaneous recovery or treatments and a clinical sign of MM was improved. In the future, we suggest that studies of assessments of MM after rehabilitation and treatment interventions of MM on stroke patients.

In this paper, torque characteristics analysis of Synchronous Reluctance Motor with the cylindrical rotor type by winding function theory(WFT) is described. The stator is same as one of the induction motor. From the d-axis, q-axis flux density distribution, to calculate self and mutual inductances needed to calculate the torque of the machine by using winding function theory the new equivalent geometry of rotor was proposed. D-axis, q-axis flux densities, self inductance and torque characteristics were obtained. From the comparison with results of finite element analysis the proposed method was verified.

This paper describes the current- based compact digital motor protective relay for low and high voltage induction motors, which are widely used in industrial and commercial power systems. The existing protective relays for motor protection had only overload, short circuit, reverse phase, open circuit and grounding protective elements, and measurement, start/stop control function. But in present day, for automation system, various functions are required, especially motor management and sequence control function and more. To meet these requirements, we developed an economic current-based compact digital motor protective relay which had various function to control, manage and monitor the induction motor.

The purpose of this study was to identify the effects of an upper extremities group exercise program based on motor learning in chronic stroke patients and to assess improvements in upper sensory motor function and activities of daily living (ADL). Five chronic stroke patients participated for the duration of 25 weeks. On the assessment of motor and process skills, there was a statistically significant improvement in motor area functioning in 4 of the subjects. In process area functioning, there was a statistically significant change in 3 of the subjects. Therefore, further studies are needed to assess sensorimotor area and ADL changes in chronic stroke patients to reduce medical cost and assess for positive psychological changes.

In this paper a new dynamoelectric winch system is introduced which is widely applied in shipping. building, architecture and so on. Generally in the winch system the squirrel cage induction motor is used as prime mover and line voltage is directly applied to the induction motor during operation. So it is difficult to obtain the smoothing revolution. because of variation of the weight of cargo and system operating method. Based on above reasons, the switched reluctance motor (SRM) is proposed to replace the induction motor because of more reliable mechanical structure, better traction characteristic and higher efficiency compared to induction motor. And in order to solve smoothing revolution problem, instantaneous torque control method based on torque sharing function (TSF) is used. Finally the validity of the proposed method is verified through the simulation and experimental results.

Background: The purpose of this study was to present a practical method of medical treatment to improve the balance and motor ability of the mentally retarded child with a single mentally retarded child-subject. Methods: The subject of the study was a 39-month-old mentally retarded female. This study included a 2-week basic period and a 13-week treatment period. The treatment method was based on the Bobath Approach. Gross motor function measurement (GMFM) was used to examine changes in motor ability, and the Pediatric Balance Scale (PBS) was used to measure changes in balance ability. The curative program was composed of normalization of muscle tone, strengthening of leg endurance and muscular strength, the improvement of trunk alignment, and the increase of balance. Visual rate of change was used to examine the results. Results: As a result of this study, balance ability increased on the Pediatric Balance Scale (PBS) by 24 points, and motor function increased in terms of Gross Motor Function Measurement (GMFM) by 6.9% (18 points). Standing increased by 41% (16 points), and walking, running, and jumping increased by 31.9% (23 points) compared to thebasic period. Therefore, the Bobath Approach appears to be an appropriate method to improve balance and motor ability in mentally retarded children. Conclusion: It is surmised that aggressive intervention by physical therapists and occupational therapists, and a follow-up study, are required for the growth of motor ability in mentally retarded children.

Objective : Major complaints of carpal tunnel syndrome (CTS) are sensory components. However, motor deficit also impedes functional status of hand. Contrary to evaluation of sensory function, the objective, quantitative evaluation of median nerve motor function is not easy. The motor function of median was evaluated quantitatively using load cell and its correlation with findings of electrodiagnostic study (EDS) was evaluated. Methods : Objective motor function of median nerve was evaluated by load cell and personal computer-based measurement system. All of the measurement was done in patients diagnosed as having idiopathic CTS by clinical features and EDS findings. The strength of thumb abduction and index finger flexion was measured in each hand three times, and the average value was used to calculate thumb index ratio (TIR). The correlation of TIR with clinical, EDS, and ultrasonographic findings were evaluated. Results : The TIR was evaluated in 67 patients (119 hands). There were 14 males and 53 females, mean age were 57.6 years (range 28 to 81). The higher preoperative nerve conductive studies grade of the patients, the lower TIR was observed [p<0.001, analysis of variance (ANOVA)]. TIR of cases with thenar atrophy were significantly lower than those without (p<0.001, t-test). TIR were significantly lower in patients with severe median nerve swelling in ultrasonography (p=0.042, ANOVA). Conclusion : Measurements of median nerve motor function using load cell is a valuable evaluation tool in CTS. It might be helpful in detecting subclinical motor dysfunction before muscle atrophy develops.

The objective of this study was to evaluate the effects of mirror therapy on motor function recovery following a stroke through a systemic review and meta-analysis. In total, nine of the 48 studies were identified from search engines between 1997 and 2011, as well as from a review of the reference lists of each identified study. The quality of each study was assessed using Jadad scale, and the effect size was calculated as a Cohen's effect size using MetaAnalyst (Beta 3.13). The overall effect size of the mirror therapy was 2.005 (95% confidence interval=1.041~2.970) in a random-effects model. This finding suggests that mirror therapy is beneficial for improving motor function following a stroke. The results from the subgroup analysis according to categorical variables were as follows: First, the effect size was larger for an onset time of less than 1 year (1.166) than for a duration of 1 year or more (.668). Second, the effect size of unpublished dissertations (1.610) was larger than published articles (1.221). Third, motor recovery of upper extremities (1.609) had a greater effect than motor recovery of lower extremities (.903). The major limitation of this study is the relatively small study population. Therefore, further individual studies of mirror therapy should be conducted in order to generalize the effects. In addition, mirror therapy supervised by a physical therapist should be recognized as a potential approach to manage motor function following a stroke and recommended to patients to improve their motor function.
