  • Objective: The purpose of this studyaimed to investigate the effects of scapular stabilization training using the different exercise prop for impingement syndrome of factory workers. Design: A randomized controlled trial Methods: Twenty shoulder impingement syndrome subjects were randomly divided into two groups of ten subjects each. Inclusion criteria was presence of positive sign in at least two of Neer test, Hawkins test, Yocum test, Jobe test and Speeds test. Andexclusion criteria, those with surgical history of rotator cuff, those with disease in upper limb other than shoulder impingement syndrome, those who took anti-inflammatory drugs over the past 12 months were excluded from the sample. One group was performed scapula stabilization exercise using elastic bands, while dumbbell group performed the exercise using dumbbell. Both groups performed the exercise after applying the general physical therapy. After applying five days a week for a total of six weeks, range of motion of shoulder joint, muscle strength and pain and function level were evaluated. Results: After the intervention, in both groups, all dependent variables at the 6-week post-test significantly improved compared with the pre-test (p<0.05). In addition, elastic band exercise group showed a significant differences in SPADI function score and SPADI total score compared to the dumbbell group(p<0.05). Conclusions: The elastic band training may be effective methodology using low-to-moderate intensity resistance for SPADI scores.

  • We need to study about lower extremity alignment because the structure dictates the function of lower extremity. Through lower extremity alignment assessment in static posture, we recognize abnormal structural conditions which could affect dynamic motion such as gait. To evaluate of lower extremity alignment provide so many useful information, but method of measurement is so limited. Therefore, this review will assist understanding for measurement of lower extremity alignment in static posture. From now on study about the objective measurement method must be achieved much more in physical therapy.

  • In this paper, and optimum profile of a cam being used in a VTR Deck mechanism is designed by the response surface analysis. The objective function of the design is to reduce driving torque of the pinch roller system that is used to compress video tape to the capstan motor axia. The pinch roller system that will be designed is modeled using the general purpopse mechanism analysis program DADS. The computer model is compared with the physical system for reliability. A model function to represent relationship between design variables and the objective function is estimated by the response surface analysis. Once the model function is reliably estimated the optimal design is carried out using the model function and each design variable's boundaries. To verify improvement of the pinch roller system, a prototype for the pinch rooler system is made and tested. From the test result, an optimum cam profile to resuce driving torque of the pinch roller system is verified.

  • The objective of this study was to identify the effects of the cognitive performance of stroke patients on their motor function recovery after comprehensive rehabilitation management. The subjects of this study were 41 stroke in-patients of the Rehabilitation Hospital, College of Medicine, Yonsei University, hospitalized during the period from September 1, 1997 to May 5, 1998. The cognitive performance was measured using a Mini-Mental State Examination(MMSE) and the motor function recovery using Motor Assessment Scale(MAS). The data were analyzed by the paired t-test, independent t-test, a one way ANOVA, and Pearson's correlation coefficiency. The findings were as follows: 1. There was a significant difference found in the motor function recovery level after the comprehensive rehabilitation management. 2. There was no significant difference found in relation to sex, age, cause of stroke, laterality of paralysis and the level of spasticity. However, there was a big difference between pre- and post-treatment regarding the treatment period. 3. In line with the cognitive performance level, there was a significant difference found in the motor function recovery level after the comprehensive rehabilitation management. 4. The correlation between the elements of the cognitive performance and the motor recovery was found to be high in orientation, attention, calculation, and language. Those elements were expected to give larger effects on motor recovery after the comprehensive rehabilitation management. Based on this study, the cognitive performance level was found to play an important role in bringing effects on motor recovery after the comprehensive rehabilitation management of stroke patients. And the evaluation on the motor recovery based on quality would be also expected to be examined, as well as the cognitive performance level test accompanied by Intelligence Quality(IQ) test.

  • Objective: This study investigated the effects of combining both mobilization and hold-relax (HR) technique on the function of post-surgical patients with shoulder adhesive capsulitis. Design: Randomized controlled trial. Methods: Forty-five surgical patients with shoulder adhesive capsulitis participated in this study and were randomly divided into three groups; both mobilization with movement (MWM) and HR technique (HR-MWM) group (n=15), the MWM group (n=15), and control group (n=15). All participants received three different interventions; 1) MWM combined with HR technique in PNF stretching on the shoulder, 2) MWM on the shoulder, 3) general physical therapy and intervention with neither MWM or HR stretching. Pre- and post-intervention, each subject was randomly evaluated for shoulder flexion range of motion (ROM), shoulder flexor muscle strength, Visual Analogue Scale (VAS), and the Korean version of the Shoulder Pain And Disability Index (SPADI). Results: The MWM combined with HR technique group had significant effects on shoulder flexion ROM, shoulder flexor muscle strength, VAS and SPADI compared to the MWM and control group (p<0.05). The MWM group showed a significantly greater increase in shoulder flexion ROM compared to the control group (p<0.05). Conclusions: These findings suggest that combining both the MWM and HR technique on the shoulder may more effectively improve shoulder function than MWM alone or without MWM&HR technique. Therefore, combining both the MWM and HR technique is a suggested intervention for increasing function due to shoulder adhesive capsulitis after surgery.

  • Purpose: The objective of this study was to offer clinical primary data that it's aims to examine effects of transcranial direct current stimulation (tDCS) on cognitive function and biochemical change of rat with alzheimer's disease(AD) induced by injecting scopolamine. Methods: Subjects were instructed cognitive dysfunction model, rat of Sprague-Dawley system was injected with scopolamine and each experimental group was classified into three; group I (n=16) is non-treatment groups; group II (n=16) is applied with the tacrine; group III (n=16) is applied with the tDCS. The ziggurat task test was conducted to observe behavioral changes and cognitive function ability and 7, 14, 21, 28 days after the model. Acetylcholine Esterase (Ach E) activity was examined for biochemical assessment of which the results are followed. Results: Participants showed as to behavioral change, tacrine application group was the most significantly responded, following tDCS application group. As to biochemical change, same as above, tacrine application group was the most significantly responded, following tDCS application group. Conclusion: From these results, confirm that tDCS application to rat with alzheimer's disease leads to positive effects on behavioral, cognitive function changes, and biochemical changes, lasting for certain period of time. This study, in particular, tDCS, which can change excitability of brain cells non-invasively, could provide basic data that is useful as a new treatment way for the patients with cognitive dysfunction.

  • Background: Cervical mobilization has been applied mainly for the improvement of arm and neck movements and pain reduction, and little research has been done to improve the executive function. Since this kind of so-called mechanical neck pain is one of most common symptoms, there are controversial issues about this with spine alignment. Posteroanterior (PA) mobilization from the Maitland concept is a process of examination, assessment, and treatment of neuromusculoskeletal disorder by manipulative physical therapy. Objective: To examine the short-term benefits of mobilization for patients with non-specific neck pain. Design: Dual-group Pretest-Posttest Design from the Quasi-Experimental research Methods: Fourteen participants (male 8, female 6; 20's of their age) with non-specific neck pains which are distributed all the unilateral or bilateral body side were recruited. Participants were categorized to Neck Pain with Movement Coordination Impairments (NPMCI) and Neck Pain with Mobility Deficits (NPMD) groups according to the results of physical examination. Professional physical therapist who has over 15-years-of clinical experience applicated manipulative therapy for the neck pain, an occupational therapist only conducted evaluations; K-NDI (Korean version of the Neck Disability Index), VAS (Visual Analog Scale), BDS-K (Korean version of Behavioral Dyscontrol Scale) for decreasing possible adverse effects; there were no person who reported other symptoms followed 4 weeks from the trial. Results: In the NPMCI group, data analysis indicated statistical differences between the PA mobilization interventions in NDI and BDS-K; even though, pain was reduced in VAS, this is not a significantly differ. In the NPMD group, data analysis represented statistical differences between the PA mobilization interventions in NDI, VAS and BDS-K; the scores were represented to be increased or the pain got relief. Conclusions: PA mobilization techniques according to Maitland concept have beneficial effects in patients with neck pain and other clinical positive effects which included neck disability, pain itself and motor function of upper extremity.

  • The purpose of this study was to describe the perceived burden of the stroke patient's caregiver and related factors to analyze relationships between perceived burden and social supports. A convenient sample of 225 caregivers who take care for a stroke patient at home participated in this study. Caregiver's perceived burden was measured by the objective and subjective burden scale developed by Montgomery (1985). Related factors of burden were studied in terms of the patient's instrumental activties of daily living, cognitive function, caregiver's demographic variables and caregiver's illness intrusiveness. The results were as follows: (1) The mean of objective burden score was 4.5, and subjective burden score was 3.1. These scores show that caregivers perceive moderate level of burden. (2) Caregivers' objective burden was significantly related to caregivers's illness intrusiveness (r=.62), patient's IADL (r=-.33), and patient's cognitive function (r=-.15). The subjective burden was related to the caregiver's illness intrusiveness (r=.29), the patient's IADL (r=.24), and the caregiver's age(r=.23). (3) The percentage of stroke caregivers who perceived physical support was 49.1%. The percentage of those who perceived emotional support was 61.0%, and those who perceived financial support totaled 37.6%. (4) Caregivers who received any type of social supports perceived lower subjective burden, and caregivers who received physical or psychological support perceived lower objective burden. These results emphasized the necessity of a rehabilitation programs for stroke patients and support program for family caregivers.

  • Objective: In general, macular degeneration, cataracts and glaucoma generally cause visual injury in clinical settings. This study aimed to examine the effects of low visual acuity simulations on hand manual dexterity function and brainwaves in healthy young adults. Design: Cross-sectional study design Methods: This study was an observational, cross-sectional study. Seventy healthy young adults participated in this study. To evaluate the effects of low visual acuity simulations on hand function and brain waves, this study involved four different visual conditions including (1) normal vision, (2) simulated cataracts, (3) simulated glaucoma, and (4) simulated macular degeneration. The hand function was measured to use the Minnesota manual dexterity test (MMDT), and the brainwaves was also measured to use the electroencephalography. Results: In hand function, placing and turning performance on the MMDT in the normal visual condition was significantly different than that in the cataract and macular degeneration conditions (p<0.05), and the placing performance was significantly differred in the normal condition than that in the simulated glaucoma. However, turning was not significantly different in the normal condition than that in the simulated glaucoma. The alpha, beta, and gamma waves did not significantly differ among the four visual conditions (p>0.05). Conclusions: The results suggest that limited visual information negatively affects the ability to perform tasks requiring arm-hand dexterity and eye-hand coordination. However, the effectiveness of low visual acuity on the brainwaves should be further studied for rehabilitative evidence of visual impairment.

  • 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.
