The purpose of this study was to study for the change of neural adaptation by muscle contraction force when neuromuscular electrical stimulation(NMES) was applied. Sixteen subjects(8 male, 8 female) without neuromuscular disease volunteered to participate in the study. All subjects were divided into two subgroups: control(no electrical stimulation) group, NMES(50% maximal voluntary isometric contraction) group. NMES training program was performed in the calf muscle over three times a week for 12 weeks. Before and after experiment MVIC of ankle plantar flexor was measured by use of dynamometer. H-reflex and V-wave in tibial nerve were measured. The following results were obtained; MVIC and V/Mmax ratio were significantly increased in the electrical stimulation groups. However, H/Mmax ratio was not changed. It was closely relationship between MVIC and V/Mmax ratio. In this study, the effect of neural adaptation of central neural adaptation was found in this study. Accordingly, NMES means not only a change of muscle fiber and skeletal muscle volume but also a effect of neural adaptation of central neural drive. Also, it was found that there was closely relationship between MVIC and neural adaptation of central neural drive by NMES.

Purpose: The purpose of this study was to examine the effects of proprioceptive neuromuscular facilitation (PNF) wrist taping, after the application of a rhythmic stabilization (RS) technique, on the decrease of pain and the increase of grip strength in physical therapists who complained of wrist pain and to provide basic data on interventions for wrist pain patients. Methods: The subjects were 15 peoples in their 20s who complained of pain with a visual analogue scale (VAS) at five points or higher due to overuse of their wrists. They were randomly assigned to a control group, to which PNF wrist taping was applied after stretching (n=7), or to an experimental group (n=8), to which PNF wrist taping was applied after application of the RS technique of PNF. The experiment was conducted for four weeks, five times per week. VAS was measured in order to measure pain decrease, and grip strength (GS) was measured using a dynamometer. In order to compare within-group differences before and after the intervention, a paired t-test was performed, and in order to compare differences between the two groups, the analysis of covariance (ANCOVA) was used. All statistically significant levels were set at ${\alpha}=0.05$. Results: There were significant differences in changes of VAS and GS within each group before and after the intervention (p<0.01), but there was no significant difference between the two groups. Conclusion: This study applied PNF wrist taping after the application of stretching or PNF RS to patients who complained of pain beyond a sense of discomfort; these interventions resulted in a decrease in pain and an increase in the grip strength of the subjects. Taping and therapeutic techniques using PNF are considered to be usefully applied as one of the programs to improve wrist pain patients' pain and grip strength.

Purpose: This study examined changes in gait speed and stride length after an intervention involving simultaneous scapular and pelvic patterns of proprioceptive neuromuscular facilitation in a hemiplegic patient. Methods: A 58-year-old woman with left hemiplegia who had complained of slowness of gait speed and weakness of leg strength took part in an intervention involving scapular postdepression patterns on the affected side and pelvic postdepression patterns on the nonaffected side. The intervention was performed with the patient lying on her left side, in a half kneeling position, and in a standing posture. Rhythmic initiation was used for teaching the movements to the patient and improvement of kinesthesia, and a combination of isotonic was employed for increasing strength and irradiation of the scapula and pelvic movement. The intervention took place for 30 min. It was implemented twice a day, 5 days a week, for 3 weeks. After three repetitions, the average time taken to complete the 10-m walk test (10 MWT), in addition to stride length, was measured to determine gait speed. Results: After the 3-week program, the patient's performance in the 10 MWT improved from 21.7sec to 17.1sec, and her stride length improved from 31.4cm to 38.7cm. Conclusion: The results showed that trunk movement exercise, especially coordinative movements of the scapula and pelvis can improve gait speed and stride length by increasing trunk stability and mobility. A combination of pelvic and scapular patterns can facilitate trunk rotation, thereby improving gait speed and stride length.

PURPOSE: This study examined the effects of the chopping pattern of proprioceptive neuromuscular facilitation (PNF) on the neglect, balance ability, and activities of daily living in stroke patients with hemi-spatial neglect. METHODS: Twenty stroke patients with neglect volunteered for this study. The subjects were assigned randomly to either the experimental group (EG, n=10) or control group (CG, n=10). The chopping pattern of PNF and exercise therapy were applied in the EG and CG, respectively, for four weeks. Neglect, balance, and activities of daily living were evaluated at the pre-and post-intervention. The assessment tools included a line-bisection test, balance test using Space balance 3D, and modified Barthel index. The pre-and post-intervention values were compared in each group using a paired t-test and the between-group differences were assessed using an independent t-test. Statistical significance was set to ${\alpha}=.05$ for all variables. RESULTS: Significant differences were observed between the EG and CG in terms of neglect, balance, and activities of daily living (p<.05). Both groups showed significant improvement in neglect, balance, and activities of daily living (p<.05). CONCLUSION: These results suggest that the chopping pattern of PNF is effective in improving the hemi-spatial neglect, balance, and activities of daily living in stroke patients with neglect.

Purpose: The objective of this study was to identify functional problems, including walking ability, of patients with strokes using the International Classification of Functioning, Disability, and Health (ICF) and to present a method that could solve functional problems, thereby determining the applicability of the ICF to increase the quality of evaluation and intervention in clinical fields in the future. Methods: Information on stroke patients who were admitted and treated in a hospital was collected. The authors conducted evaluations, interventions, and measurements of the results of the ICF tool in order to improve gait abilities of patients. The subjects were trained using proprioceptive neuromuscular facilitation (PNF) one hour a day and five times a week for four weeks. The result measurement variables were a six-minute gait test, 10 m velocity test, gait instability test, and measurements using the ICF sheet. Results: In the six-minute gait test, gait distance increased by 48 m, from 102 m to 150 m. The gait velocity test result showed an improvement from 0.36m/s to 0.44m/s. The subjects performed a gait instabilitytestwithacupfilledwith50mmwater. In the gait instability test, the amount of water was 38 mm before the intervention; however, it was 50 mm after the intervention. The gait velocity with a cup filled with water improved from 0.25m/s to 0.31m/s. Conclusion: An evaluation and intervention were designed with the ICF tool for stroke patients. Gait abilities improved when the PNF technique was used. The IFC method can be used for evaluation and intervention, and it could help improve gait abilities of stroke patients.
