The purpose of this study were to evaluate and compare the balance ability at different conditions in normal 20 to 29 years old on unstable platform, KAT 2000(Breg, Inc., Vista, CA. 1994). Static and dynamic BI(balance index) were measured 3psi and 5psi surface conditions. Static tests were done on right and left leg separately, then both legs together with the feet apart 20cm with the eyes opened and closed. Dynamic tests were done on both legs together with apart 20cm with the eyes opened. A dynamic test was performed in which the subject moved platform in a circular manner to chase a moving object on a computer screen. Seventy healthy students(average 21.6 years, male, female) were tested. In this study applied the paired t-test and correlation to determine the statistical significance of result. The results were as follow: 1) The mean static balance index of the Rt leg was on 3psi surface condition with the eyes opened, and that of the Lt leg was . 2) The mean static balance index of the Rt leg was on 5psi surface condition with the eyes opened, and that of the Lt leg was . 3) The mean static and dynamic balance index of both legs were , on 3psi with the eyes opened, and , on 5psi respectively. 4) The mean static balance index of the Rt leg was on 3psi surface condition with the eyes closed, and that of the Lt leg was . 5) The mean static balance index of the Rt leg was on 5psi surface condition with the eyes closed, and that of the Lt leg was . 6) The mean static balance index of both legs was on 3psi surface condition with the eyes closed, and that of the 5psi was . 7) The balance index on 3psi surface condition was significantly higher than that of 5psi (p<0.05, p<0.01). 8) The balance index with the eyes closed was significantly higher than that of the eyes opened (p<0.05). 9) The balance index on the left leg was significantly higher than that of the right leg (p<0.05, p<0.01). 10) There was no correlation between static balance index and dynamic balance index. 11) Therewas no correlation between weight or height and balance index.
The purpose of this research is to identify traction effects for the treatment of scoliosis and compare the effects among patients as their own physical characters. In this research, the patients with scoliosis hospitalized for ten days have treated in the way of the static traction for twenty hours a day, and alternating lumbar and cervical traction for twenty minutes two times a day in the department of rehabilitaton of Yong-Dong Severance Hospital. The followings are the conclusions of this research: 1) The traction for the patients with scoliosis is effective treatment method to reduce the curved angle (p<0.001). 2) Statistically there is no significant difference of the reduced curved angle between male and female after the traction (P>0.05). 3) Statistically there is significant difference of the reduced curved angle among age groups after the traction (P<0.05). 4) Statistically there is significant difference of the reduced curved angle among curved angle groups after the traction (p<0.001). 5) Statistically there is no significant difference of the reduced curved angle among shapes of curved angle after the traction (P>0.05).
Manual dextrity is frequently evaluated in rehabilitation to estimate hand function. The Box and Block Test(BBT) mearsures gross manual dextrity. The first goal of this study was to verify the test-retest reliability of the BBT for 4, 5 years old children. The second goal of this reserch was to develop normative data from 35 convenient sample of normal children. The results showed the test-retest reliability was high (Pearson product moment correlation coefficients of 0.71 to 0.82).
The purpose of this case study was to introduce functional electrical stimulation(FES) for paraplegic patients. FES provides the ability to rise from sitting to standing, maintenance of a standing position, and the ability to walk with a reciprocal gait. Six channels of electrical stimulation are sufficient for synthesis of a simple reciprocal gait pattern in these patients. During the double-stance phase, knee extensor muscles of both knees are stimulated, providing sufficient support for the body. Only one knee extensor muscle group is excited during the single-stance phase. The swing phase of the contralateral lower extremity is accomplished by eliciting the synergic flexor muscle response through electrical stimulation of afferent nerves. The transition from the double-stance phase to the swing phase is controlled by two hand switches used by the therapist or built into the handles of the walking frame for using by the patient. A twenty-five years old male was with a T9/T9 spinal cord injury due to a traffic accident and admitted to Yonsei Rehabilitation Hospital for comprehensive treatment. After 30 days of training using the Parastep(R) he was able to stand for 10 minutes. After 43 days, he was able to walk and at discharged he could walk for 100 meters.
The purpose of this study was to compare and evaluate various hand functions in the most common position (chair sitting, standing, floor sitting) used by cerebral palsied children with spastic diplegia. The results, analysed statistically, could be useful in suggesting treatment strategy for the improvement of hand function in such patient. For this study, 27 children mild or moderate spastic diplegia were chosen. They were patients of the Rehabilitation Hospital, Yonsei University Medical Center. Both dominant and nondominant hands were tested by the Box and Block Test. Bilateral hand function was tested by bead striding and card sorting activities. Collected data was analysed using univariate correlation analysis and MANOVA. Results were as follows: 1) In chair sitting there was a significant positive correlation between dominant hand scores in the Bloc and Box Test and chronological age, gestation period, and time of treatment initiation. In bilateral hand function, card sorting scores correlated positively with time of treatment initiation. 2) In standing, there was a significantly positive correlation between dominant hand scores in the Block and Box Test and time of treatment initiation. 3) In floor sitting, there was a significantly positive correlation between the dominance hand scores in the Block and Box Test and the tine of treatment initiation. Bead stringing, a bilateral hand activity, correlated positively with gestation period and birth weight but negatively with the postnatal incubation period. 4) That score of children who walked showed no significant difference in any of the three postures. 5) Highest test scores in children who could nat walk were in the Box and Block Test for nondominant hand in bead stringing for bilateral hand function. There scores occurred with the children in thee chair sitting posture. The results showed that, in order to improve hand function in children with spastic diplegia, it is necessary to maintain a well supported upright trunk posture with variations allowed for relevance to the chosen position of thee improvements hand activity being performed.
The purpose of this study was to assess the biomechanical effects of corset and back brace for low back pain syndroms patients. The subjects of this study were 69 patients with low back pain syndroms who had been hospitalized or were visited out-patient department of the rehabilitation hospital, college of medicine, Yonsei University, from October 5, 1995 through November 5, 1995. Clinical results and datum were obtained by phone calls and chart reviews of low back pain patients. The results were as follows: 1) Fifty - nine subjects recovered over a good grade (85.6%). 2) The standing workers had a little effect of brace for low back pain. 3) After using a corset and back brace, the test of SLR increased from 36.23% to 72.47%, and the ability of ambulation improved from 40.57% to 85.5%. In conclusion, the biomechanical effects of corset and back brace for low back pain patients were found to be decrease pains and improve posture and ADL function.
This study was performed to assess the efficacy of high voltage pulsed galvanic current for the healing of wounds in rabbits. Skin wounds were created laterally on the flank of 12 domestic rabbits(). The wounds of each group were treated with an intensity of 170 V at a frequency of 70 pulses per second, which was applied for 30 minutes a day for 10 days. The experimental groups were randomly assigned to either EXP I (n=3), EXP II(n=3), EXP III(n=3) or control(n=3). Each group was stimulated under the following conditions : 1) EXP I (Negative polarity), 2) EXP II (Change in polarity, negative electrode stimulation during the first 3 days and then positive electrode stimulation from 4 to 10 days), 3) EXP III(Positive polarity), 4) control(No stimulation). An active electrode was placed over the wound and a dispersive electrode on the buttock. The rate of wound closure was compared with the original wound size, evaluated by a tracing film in each measurement period. Finally, on the wound in each group, skin tissue was excised for histological evaluation after treatment for 10 days. The results obtained are as follows : 1) It was found that the control group did not show a complete remodeling of epitherial layer and had a chronic inflammatory response. Judging from the irregularity of intercellular space and the loose alignment of connective tissue, these findings show that wound healing was delayed. 2) EXP I showed a significant bactericidal effect, but a moderate response of vasodilation. The rate of wound closure was slower when compared with EXP II, III. 3) EXP II showed a complete remodeling of epitherial layer and a positive repair of connective tissue. Its rate of wound closure was best when compared with the others. 4) EXP III had a slower rate of wound closure than EXP II, but judging from the greater proliferation of collagen fibers and the dense alignment of connective tissue, this positive electrode was very effective in the formation of neo - connective tissue.
Normal balance is defined as state in which the body is equlilibrium. It is complex motor control task, requring integration of sensory information, neural processing, and biomechanical factors. There are major two factors contribute to balance control, the neurological and the musculoskeletal. The neurological factor provides the sensory processing and motor output mechanisms that are the neurophysiological basis for response. The musculoskeletal factor provides the mechanical structure for response. When all components of two factors are operating effectively, the postural response should be appropriate and effective for good balance control. Therfore, balance can be influenced by above all factors. In addition, balance can be also influenced by muscle tone, hearing, physiological factors, and environmental factors. Physical therapists must understand factors of balance control so that we can accurately assess balance. Therefore, physical therapists have to develop useful balance measurement tools to evaluate balance.
