  • An A-B-A-C single subject research design was used to assess the effectiveness of transcutaneous electrical nerve stimulation(TENS) and inhibitive techniques on spasticity in a 10-year-old girl with cerebral palsy. Stimulation electrodes were placed over the sural nerve of the right leg. The standard method of cutaneous stimulation, TENS with impulse frequency of 100 Hz, was applied. Inhibitive techniques including stretch, antagonist contraction, and weight bearing were used. The tonus of the leg muscle was measured by means of a surface-EMG biofeedback unit. Visual analysis of data indicate that the child showed clinically significant reduction of spasticity in passive ankle movement following 30 minutes of TENS and inhibitive techniques application, respectively. The effect of TENS on spasticity inhibition was similar to that of inhibitive techniques. This result suggests that for this child with cerebral palsy, the application of TENS to the sural nerve may induce short-term post-stimulation inhibitory effects on the spasticity of cerebral palsy. Replication of this study with a more complex single-subject design involving more subjects is recommended to confirm this result.

  • Purpose : The neurologically impaired patients have sensory, motor, cognition, perception problems which cause reduction of body schema, balance control and postural control provoke disfunction. The purpose of this case report was to evaluate effects on gait&balance upon improvement of postural control for left hemiplegia. Methods : This study has performed single subject design from March to April 2013 for 6 weeks. The subject of this study was a 67years old female patient with left hemiplegia. Timed Up and Go (TUG) test and Functional Reach (FR) test were used as evaluation tool. The subject was treated 5 times a week for 30 minutes each. Results : The result is that the walking velocity was decreased, the ability of gait was improved than before the training. The length of FR was increased from 8.33cm to 22.67cm. Conclusion : According to the results, the treatment improves subject's ability of walking in this study.

  • Objectives : This study was designed to evaluate the effect of moving cupping therapy on the edema of paretic hand in stroke patients. Methods : The subjects were stroke patients with flaccid hemiplegia. Each subject's routine therapy program was maintained throughout single subject ABAB design. During the first week, baseline data were gathered. During the second and fourth week, intervention was provided(total 20minutes of moving cupping therapy, from contralateral to ipsilateral, distal to proximal). During third and fifth week, data were gathered with treatment withdrawn. Edema was measured with hand volumeter and measuring tape. Basically Bayesian analysis was performed using WinBUGS(ver. 1.4), for addition, visual graph and mean score were also presented for comparison between treatment(moving cupping therapy) and non-treatment. Results : The visual graph and mean score showed decrease in edema during the treatment weeks. Overall decrease in edema by moving cupping therapy was verified significantly by using Bayesian ana-lysis(95% credibility intervals). Conclusions : This study suggests that moving cupping therapy could be applicable for reducing post-stroke hand edema. Further research would be needed to establish guidelines for use.

  • The purpose of this single subject care study was to evaluate the effectiveness of a functional electrical stimulation(FES) treatment program designed to prevent glenohumeral pint stretching and subsequent subluxation and shoulder pain in hemiplegic patients. The subject was a 43-year-old male who had left side hemiparesis with shoulder pain and subluxation on affected side. He received conventional physical therapy and additional FES therapy where two flaccid shoulder muscles, supraspinatus and posterior deltoid. were induced to contract repetitively up to 20 minutes for 2 weeks. As a result. the patient showed improvements in hemiplegic arm function, reduction in subluxation(as indicated by Jig test) and range of motion(SLROM). But it was difficult to generalize. We concluded that the FES program was effective in reducing the severity of shoulder subluxation and pain. Further study must be evaluated its statistical significance.

  • The geometrical initial imperfection is generally described that a dome digeresses from ideal shape. In actual domes the mode and amplitude for initial imperfection appear variously and affect buckling-strength sensitively. This study investigates the buckling characteristics of single-layer latticed domes with triangular network subjected to initial imperfection. Additionally, this study is to get the data that are to formulate the general equation taking initial imperfection into consideration.

  • The purpose of this study was to identify the effect of the Peer Relationship Program on the school adjustment of Ha-nul with the school maladjustment by peer problems. To achieve this purpose, single subject pretest-pottiest design was implemented for Ha-nul with school maladjustment in the third grade of the elementary school. As for the testing period of this study, this program was carried out one time a week for 10 weeks from Sept 11, 2006 to Oct 13, 2006. Each test lasted for $40{\sim}60$ minutes. To find out changes in the school adjustment of the subject child, the progress in change before and after tests was comparatively analyzed through a Likert-type three-step evaluation scale and presented as tables and graphs regarding the target behavior table. And the school adjustability was calculated in terms of percentage and presented as tables and bar graphs through a Likert-type four-step evaluation scale. Change in the subject Ha-nul's behavior, which was shown in test scenes, was observed and recorded and then Qualitatively analyzed. The following conclusions were drawn from the results of this study: First, the Peer relationship improvement program was effective in the positive influence to the relationship between a teacher in charge and Ha-nul with the school maladjustment This program made a confidence and increased the ability to express one's own ideas and feelings to others. Second, the Peer relationship improvement program was effective in the positive influence to the relationship between schoolfellows and Ha-nul with the school maladjustment This program provided the opportunities to get along with peers naturally and the abilities of a mutual understanding. Third, the Peer relationship improvement program was effective in the partially positive influence to Ha-nul with the school maladjustment. Fourth, the Peer relationship improvement program was effective in the positive influence to follow the school rules by experiencing a role, concession and fairness through the various activities. Fifth, the Peer relationship improvement program was effective in the positive influence to take part in the school event with a self-confidence and cooperation with peers through the various activities.

  • The purpose of this study was to determine the effect of custom seating system on upper extremity access to mouse for a child with cerebral palsy. A single-subject ABAB design was used with one 13years old participant. The measurements were response time and accuracy of mouse click in the participant's typical position and in an intervention position. The intervention position was taken by using current clinical guideline and research on promoting upper extremity movement. The intervention position was achieved through hands-on postural support to the participant's typical seating. The results of this study were as follow: first, response time was decreased in the intervention position compared with the typical seating. Second, accuracy of mouse click was highly in every phases. So further analyses were not conducted on these data. The results of this study provide empirical evidence of the positive effects of functional seating on access to mouse for children with cerebral palsy. Further research is required to confirm the positive effect of the custom seating system across other disabilities type and more subjects.
