The purpose of this study was to evaluate and compare the Limits of stability(LOS) in hemiplegic patients who can walking independently. The LOS was measured at stable surface, unstable surface with eye open and eye closed. In this study, 18 out-patients were evaluated who were treated at Yonsei University Medical Center Rehabilitation Hospital. In order to determine the statistical significance of results, T-test, paired t-test, and Kruskal-Wallis 1-way ANOVA were applied at 0.05 level of significance. The results were as follows: 1. The mean of lateral limits of stability was 9.89 degree. 2. The mean of anteroposterior limits of stability was 6.43 degree. 3. There was a significant difference of limits of stability between sound side and affected side(p<0.05). 4. The limits of stability was significantly decreased with eye closed(p<0.05) 5. The limits of stability was significantly decreased at unstable surface(p<0.05). 6. The limits of stability was a significant difference as spasticity degree of ankle plantar flexors(p<0.05). These results showed that the limits of stability in hemiplegic patients was more decreased than that of normal adult. In order to improve the balance in hemiplegic patients, we need to increase the limits of stability.

PURPOSE: This study examined the effects of functional electrical stimulation (FES) on temporal-spatial gait and the activities of daily living in hemiplegic stroke patients. METHODS: The subjects were 29 hemiplegic stroke patients (57.7 ± 10.3). The patients walked at a self-controlled speed in four states: (1) walking without FES (non-FES), (2) walking with FES on the gluteus medius in the stance phase (GM), (3) walking with FES on the common peroneal nerve and tibialis anterior in the swing phase (PT), (4) walking with both GM and PT. A GAITRite system, Timed-Functional Movements battery, and Timed UP and Go test were used to measure the variables. RESULTS: Significant improvements were observed in all variables of the GM+PT, GM, and PT states compared to the non-FES state (p < .05). There were significant improvements in the GM+PT state compared to GM and PT states (p < .05). Moreover, significant improvements were noted in the single support time on the affected side, backward walking 10ft, and side stepping 10ft on the affected side of the GM state compared to the PT state (p < .05). There were significant improvements in the stride length on the affected side and side stepping 10ft on the unaffected side of the PT state compared to the GM state (p < .05). CONCLUSION: FES is effective in improving the temporal-spatial gait and activities of daily living in hemiplegic stroke patients.

This study investigated therapeutic effects of pelvic tilt exercise (PTE) on weight bearing and body sway during sit-to-stand (STS) on 18 hemiplegic patients who had visited the Hanyang University Seoul Hospital and Injae University Sanggyebek Hospital physiotherapy rooms. The study compared the patients with 18 normal adults. The subjects were sampled out from those who could get up independently, maintain a standing posture more than 10 seconds, understand the movements of this study and have no difficulty in performing the tasks. By executing STS in a natural way with habitual movements before and after PTE, the weight bearing was measured by using Mediance II. In order to compare the difference of weight distribution, weight bearing and body sway on affected and nonaffected sides during STS before and after PTE, the Wilcoxon Signed Ranks Test was used. The statistical significance level was based on p<.05. The results revealed that the difference of weight distribution in the hemiplegic group was significantly decreased (p<.05), whereas there was no significant difference in the healthy group (p>.05). Weight bearing loaded on the affected side was $42.53{\pm}7.65%$ and $44.20{\pm}6.32%$, respectively, in the hemiplegic group during STS before and after PTE. Weight bearing during STS after PTE is increased significantly, as compared with weight bearing before PTE (p<.05). Body sway in the hemiplegic group was significantly decreased (p<.05). As mentioned, PTE proved to be effective for improvement in weight bearing on the affected side during STS of hemiplegic patients.

The aim of this study was to investigate the effects of treadmill gait training on the functional characteristics and the temporal-distance parameters of gait in hemiplegic patients, as compared with conventional gait training. The subjects of this study were 32 hemiplegic patients who had been admitted or were visited out-patients at Kangdong Sacred Heart Hospital, Hallym University, from March 3 through April 25, 2003. These subjects were randomly divided into treadmill gait training group or conventional gait training group. We evaluated the gait ability, motor functions, muscle strength, spasticity, physiological cost index, and temporal-distance parameters. We analyzed the changes between pre and post training in each groups, and the difference between two groups. Temporal-distance parameters were obtained using the ink footprint method and then energy consumption using physiological cost index. The results were as follows: 1. After a six-week training, treadmill gait training group significantly improved, as. compared to pre-training, in gait ability, motor functions for the leg and trunk and gross function, muscle strength of the lower limb, gait speed, cadence, step length both on the affected and on the unaffected side, step length symmetry, and energy consumption(p<0.05). 2. After a six-week training, conventional gait training group significantly improved, as compared to pretraining, in gait ability, motor functions for the leg and trunk, muscle strength of the lower limb, spasticity the upper limb, gait speed, cadence, step length both on the affected and on the unaffected side, and energy consumption(p<0.05). 3. After a six-week training, the treadmill gait training group significantly improved, as compared to the conventional gait, training, in gait speed and step length on the unaffected side. These results show that treadmill gait training was improved gait speed and step length on the unaffected side of hemiplegic patients, as compared with conventional gait training. Further research is needed to confirm the generalization of these findings and to identify which hemiplegic patients might benefit from treadmill gait training.

The purpose of this study was to investigate how COP displacement of a hemiplegic foot in stance phase during gait is related to clinical balance measures and the recovery stage in hemiplegic stroke patients. Twenty-eight functionally ambulant hemiplegic patients who had suffered from strokes and thirty age-matched healthy subjects participated in this study. COP parameters were calculated. Clinical balance was measured using the Functional Reach Test (FRT) and Timed Up and Go Test (TUGT). The recovery stage, proprioception, and clonus of the ankles or lower extremities were also measured for physical impairment status. The COPx max-displacement in the medial-lateral side of the stroke patients was significantly longer than that of the normal group (p=.038). The COPy max-displacement in the anterior-posterior side of the stroke patients was significantly shorter than that of normal group (p<.001). Significant differences in the COPx and COPy displacement asymmetry index were found between the two groups (p<.01). The FRT was correlated with the COPx displacement (r=.552) and COPy displacement (r=.765). The TUGT was correlated with the COPy displacement (r=-.588) only. The recovery stage of the lower extremities was correlated with COPy displacement (r=.438). The results of the study indicate that the characteristic of COP displacement in hemiplegic feet in stance phase during gait is related to balance ability and recovery in stroke patients. COP parameters acquired by the mapping of foot pressure in stance phase during gait will provide additional useful clinical information. This information can be used by clinicians to assess objectively the pathologic gait with other diseases and to evaluate the therapeutic effects on gait in stroke patients.

Objectives: This study investigated the change of foot rotation angle of gait analysis parameters according to gait improvement in post-stroke hemiplegic patients. Methods: We measured the foot rotation angle of eight post-stroke hemiplegic patients at the time of dependent and independent gait. Results: The foot rotation angle of the paralyzed side reduced closer to normal average according to gait improvement, but the non-paralyzed side not significantly. Conclusions: Improvement of foot rotation is an important thing for independent gait of post-stroke hemiplegic patients so this treatment seems worthy of being considered in clinical trials.

This study is designed to evaluate the effects of aggressive fine motor exercise of unaffected hand in the hemiplegic patients. The 36 hemiplegic patients were classified into two groups: The experimental 18, who were treated by aggressive fine motor exercise in unaffected hand and the control, 18, who were treated by conventional exercise program. We evaluate the effects of aggressive fine motor exercise by Functional Independence Measure(FIM) and Jebsen Hand Function Test(JHFT) after 6 weeks program. After exercise program, the experimental group showed score change from $43.05{\pm}15.68$ to $58.05{\pm}17.12$ in FIM score and from $24.12{\pm}22.03$ to $55.44{\pm}21.50$ in Jebsen, and the control showed score change from $51.11{\pm}22.61$ to $57.50{\pm}23.66$ in FIM score and from $40.88{\pm}21.17$ to $52.77{\pm}19.42$ in Jebsen. The experimental group had significantly higher score in FIM and JHFT than that of the control group. The aggressive fine motor exercise is beneficial in unaffected hand in the hemiplegic patients.

Purpose: The purpose of this study was to investigate the effects of constraint-induced (CI) movement using self-efficacy on U/E function of chronic hemiplegic patients. CI movement discourages the use of the unaffected U/E, combined with intensive training of the affected U/E. Method: A non-equivalent pretest-posttest design was used. Study subjects were 40 hemiplegic patients conveniently selected from 2 different community health centers. The experimental subjects participated in the CI movement program for 6 hours daily over a period of two weeks. The exercises for affected U/E consisted of warming up, main exercise and ADL practice. To encourage the participants' behaviors self-efficacy enhancing strategies were used, which included performance accomplishment, vicarious experience, verbal persuasion and emotional arousal. Result: After 2 weeks of treatment, the grip power, pinch power, wrist flexion/extension, elbow flexion, and shoulder flexion/extension were significantly higher in the experimental subjects than in the control subjects. However, there was no significant difference in hand functions of the two groups. Conclusion: The above results show that the constraint-induced movement using self-efficacy could be an effective nursing intervention for improving U/E function of chronic hemiplegic patients. Long term studies are needed to determine the lasting effects of constraint-induced movement.
