The purpose of this study was to determine the effect of mental practice on biceps brachii muscle strengthening in 3 poststroke hemiplegia patients along with multiple baseline design across subjects. The mental practice adopted for this experiment involved imagery training to practice elbow flexion, which last 12 to 16 sessions with 30 minutes each session. Maximal muscle activities was measured pre- and post-mental practice to evaluate the strength of biceps brachii. The strength of biceps brachii was measured by surface-EMG. The results were: In the subject 1, 73.92 mV (pre-) and 127.56 mV (post-); in the subject 2, 147.60 mV (pre-) and 202.85 mV (post-); and in the subject 3, 20.75 mV (pre-) and 27.92 mV (post-). The results indicate that a simple mental practice is a useful method to strengthen biceps brachii muscle in hemiplegic patients.

This paper describes the detection of spatio-temporal parameter using an accelerometer and footswitches to evaluate a symmetry and balance of hemiplegic patients. We detected gait data using a 3-axis accelerometer that mounted between L3 and IA intervertebral area and footswitches made by FSR-Sensor attached insole. To minimize the error of the gait parameters to be detected incorrectly in case of using only accelerometer, we enhancement the performance of detection by measuring an accelerometer and foots witches data at the same time. So, it was possible to detect more accurate gait parameters. As a result, we can confirm the symmetry and balance of hemiplegic patients. In the future. these results could be used to evaluate the walking ability in hemiplegic patients in clinical pratice.

Body weight support treadmill training is a new and promising therapy in gait rehabilitation of patients with hemiplegia. The purpose of this study was to identify the effects of body weight support treadmill training on gait and standing balance in patients with hemiplegia. Eighteen patients with hemiplegia participated in the study. A 10 m-timed walk test, measurements of step length and standing balance score were administered. Intervention consisted of body weight support treadmill training five times a week for 2 weeks. The data were analyzed by paired t-test. Body weight support treadmill training scoring of standing balance, step length and 10 m-timed walk test showed a definite improvement. Body weight support treadmill training offers the advantages of task-oriented training with numerous repetitions of a supervised gait pattern. The outcomes suggest that patients with hemiplegia can improve their gait ability and standing balance through body weight support treadmill training.

The use of AFO in the management of patients with hemiplegia has been somewhat controversial. The purpose of the study was to identify the influence of the plastic ankle foot orthoses(AFO) on the characteristics of pelvic tilt in the patients with hemiplegia. Sixteen hemiplegic patients participated. The angle of pelvic tilt were measured using the BROM II . Results showed that the hemiplegia who weared plastic AFO, the angle of pelvic tilt was significantly less than not weared subjects. However. duration of wearing a plastic AFO and the degree of spasticity were not affected to the angle of pelvic tilt. Therefore the patients with hemiplegia should consider using the brace for the right purpose, also need to maintain the mobility of ankle joint while wearing the plastic AFO.

The purpose of this study was to test that the exercise adaptive training enhance behavioral outcome significantly after focal brain ischemia in rats. After occlusion of middle cerebral artery in rats, they were housed in individual standard cages fur 24 hours. The control group was sacrificed 24 hours after ischemic event. The experimental group I was housed in standard cages for 7days. The experimental group ll was housed in enriched environment and had got exercise adaptive training fur 7days. The rats were examined five motor behavioral tests. In motor behavioral tests :postural reflex test, limb placement test, beam-walking test, rotarod test, horizontal wire test. The outcomes of control group and group I were significantly lower than the group II. The conclusion was that exercise adaptive training induced functional repair.

The purpose of this study was to assess of cane use on the hemiplegic gait of strock patients in temporal and spatial variables. Subjects were thirteen including 8 men and 5 women. They could walk independently without cane, To compare the effect of walking with and without a cane, temporal and spatial variables was measured using GAITRite. Cane walking demonstrated increased stance time on the affected side, and swing time, step length on the sound side were increased, and base of support was decreased. In conclusion, hemiplegic gait pattern of strock patients were improved with cane than those not using a cane.

The purpose of this study was to determine the effect of shoe lift of the affected limb in subjects with hemiplegia. The subjects of this study were 18 post-stroke hemiplegics. For the study, insole of the paretic side was lifted 10 mm higher, and static weight bearing was measured before and after the lift application. For the measurement of carry-over effect of lift, we got data of those three items prior to and 3 weeks after lift application and 3 days after removal of the lift. Static weight bearing was significantly increased both just after and continuous application of lift for 3 weeks than before. According to this study, lift applied to the shoe of the paretic limb was effective in inducing static weight bearing in the paretic limb. This study suggests that symmetry, induced by shoe lift applied to the paretic limb, could help correct abnormal posture that would be caused in standing and prevent development of abnormal muscle tone in subjects with hemiplegia caused by unilateral stroke.

The subject of this paper is to perform the basic research to make design guide as finding out the structural characteristics of polypropylene Ankle Foot Orthosis(AFO) for hemiplegics. Target shape of AFO is a solid standard type. In this study we measure ridity as dorsiflexion and thicknesses of AFO with three types of ankle widths and analyze correlation between rigidity and ankle widths, thicknesses. As a result, the rigidity characteristic is specified complex effect of ankle widths and thicknesses.

Objectives : Asymmetrical weight bearing during standing has been identified as a common problem in persons with hemiplegia. This study examined the effect of auditory and visual feedback on symmetric weight bearing with hemiplegia. Method: The intervention program was instituted for 10 min each day with a total of twelve treatment sessions. The machine which was used for this study is the Weight Balancer, OG GIKEN, WB-202, Japan Result: There was a significant improvement of symmetric weight distribution in auditory feedback group whereas the visual feedback group disclosed some improvement but not significantly. There was no significant change in control group. Conclusion: Results of this study suggest that an auditary feedback group can be more effective than visual feedback group or control group in helping the persons with hemiplegia achieve symmetric stance.

The purpose of this study is to conduct a retrospective chart audit of initial physical therapy evaluation to determine the incidence of sitting imbalance and its relationship to the side of weakness in hemiparetic patients. A review of the records of 36 patients revealed that the left side was predominantly affected in 17 patients and the right side in 19 patients. Ages, time since onset, and proportion of men and women did not difer between the left and right hemiparetic patients. About half patients(52.8%) could sit independently, but 64.7% of those with left-sided weak-ness and 31.6% of those with right-sided weakness could not. A chi-sequare analysis revealed a significant relationship between the side of weakness and independent sitting balance(p<0.1). Patients with left hemiplegia are more likely to have difficulty with independent sitting balance(p<0.1). Patient with left hemiplegia are more likely to have difficulty with independent sitting than patients with right hemiplegia, which may affect their progress in rehabilitation.
