          만성 뇌졸중 환자의 균형 및 보행 증진을 위한 체간 자가 훈련 프로그램 -예비연구-

          나은진,우영근 대한고유수용성신경근촉진법학회 2017 PNF and Movement Vol.15 No.3

          Purpose: Balance and walking ability are important elements of functional independence for people with stroke and are major goals in rehabilitation. These abilities require trunk performance, but most chronic stroke patients reach a plateau in their rehabilitation. Therefore, the purpose of this study was to investigate the effects of a self-training trunk program to improve balance and walking ability in people with stroke, and to suggest such a self-training program for integrated rehabilitation of people with stroke. Methods: The study recruited 7 people with stroke. The subjects performed trunk training for 30 min per day, 6 days per week, for 3 weeks. Participants were measured on the Trunk Impairment Scale (TIS), the Berg Balance Scale (BBS), the Korean Activities-specific Balance Confidence (K-ABC) scale, the Falls Efficacy Scale (FES), the Functional Gait Assessment (FGA), the 6 Minute Walk Test (6MWT) and a gait analysis to measure the training effects. Statistical analysis used the Wilcoxon signed-rank test as a non-parametric statistical test. Results: TIS was not significantly different after the self-training trunk program, but BBS (p>0.05), K-ABC, and FES were significantly improved after the training program (p<0.05). Furthermore, the 6MWT, stride/height %, and one-leg stance were significantly improved after the training program (p<0.05), but cadence, stance, and swing duration were not significantly different after the training (p>0.05). Conclusion: These results suggest that a self-training trunk program should be integrated into stroke rehabilitation to improve balance and walking ability, and further research is needed to develop the program to be more effective for chronic stroke patients.

          발목각도 Toe 0°, Toe in 10°, Toe out 10°에 따른 스쿼트 운동이 안쪽넓은근과 가쪽넓은근의 근두께와 지면반발력에 미치는 영향

          안수홍,이수경 대한고유수용성신경근촉진법학회 2020 PNF and Movement Vol.18 No.1

          Purpose: The purpose of this study was to investigate the differences in muscle thickness and ground reaction force of the vastus medialis oblique and vastus lateral oblique muscles during squats at ankle angles of toe 0°, toe in 10°, and toe out 10°. Methods: In this study, 9 male and 17 female students in their 20s participated in a randomized controlled trial and were compared according to the ankle angles of toe 0°, toe in 10°, and toe out 10°. To determine the reliability and measurement of muscle thickness according to ankle angle using ultrasound equipment and muscle thickness, the participants’ ankle angles-toe 0°, toe in 10°, and toe out 10°-were measured three times at the vastus medialis oblique and vastus lateralis oblique muscles during squats. At the same time, the maximum vertical ground reaction force was measured with a force plate. A total of three measurements were taken and averaged, and two minutes of squat movements were assessed between ankle angles to prevent target action. Results: The results of this study illustrated that the reliability of the vastus medialis oblique muscles and vastus lateralis oblique muscles in ankle angle was high. The difference in muscle thickness was significantly greater in comparing the toe out10° angle with the toe 0° angle than between toe in 10° and toe out 10° in vastus medialis oblique and vastus lateralis oblique (p < 0.05). There was no statistically significant difference between the ankle angle of toe 0° and toe in 10° (p > 0.05). The maximum vertical ground reaction force was significantly greater at toe out 10° than at the ankle angle of toe 0° and toe out 10° and between toe in 10° and toe out 10° (p < 0.05). There was no statistically significant difference in the comparison between toe 0° and toe in 10° (p > 0.05). Conclusion: Squatting at an ankle angle of toe out 10° increases the dorsi flexion; thus, the stability of the ankle and the thickness of both oblique muscles increased to perform more effective squats. In addition, as the base of support widens, it is thought that the stability of the posture increases so that squat training can be performed safely.

          Purpose: The purpose of this study was to show the effects of voluntary change of weight bearing on the vastus medialis oblique and the vastus lateralis ratio during squat exercise. Methods: Twenty-four healthy adults were recruited for this study. The subjects performed squat exercise with median weight bearing, lateral weight bearing and non-changed weight bearing. The muscle activities of the vastus medialis oblique and the vastus lateralis were measured during the squat for all three conditions. The measured data were analyzed using one-way ANOVA to investigate the effect of muscle activation on the each condition. The statistical analyses were performed using SPSS ver. 17.0, and a p-value of less than 0.05 was considered significant for all cases. A post-hoc test was performed using Tukey’s test. Results: The study showed that the vastus medialis oblique and the vastus lateralis ratio significantly changed according to the voluntary change of weight bearing during a squat. The vastus medialis oblique and the vastus lateralis ratio significantly decreased under the condition of voluntary lateral weight bearing. Conclusion: We suggest squat exercise on median weight bearing to increase the vastus medialis oblique and the vastus lateralis ratio. If your patient has. .

          Objectives : The purpose of this study was conducted to find change and development of the proprioceptive neuromuscular facilitation(PNF). Methods: This is a literature study with books, seminar and book for the international courses. Results: Combination of isotonic has been started by Mr and Mrs Johnson after Miss Knott passed away. It is that the terms of maximum resistance changed into optimal or appropriate resistance. It is focus on activities. Maximum resistance focus not only activities but also irradiation have to fit with normal functions. PNF has enough for the motor control concepts and international classification of functioning(ICF)of WHO. Conclusions: PNF has changed and developed with giving resistance method. It is that changed from maximal resistance to optimal resistance. But it is smaller concept than maximum resistance. Even though PNF founded 60 years ago, it is enough for new concepts that is motor control and learning.

          고유수용성신경근촉진법 운동이 무릎관절 전치환술환자의관절가동범위와 통증 및 기능적 활동에 미치는 영향

          김창헌,강태우,김범룡 대한고유수용성신경근촉진법학회 2018 PNF and Movement Vol.16 No.1

          Purpose: This study investigated the effects of proprioceptive neuromuscular facilitation (PNF) exercise on the range of motion (ROM), pain, and functional activity of patients who received total knee arthroplasty (TKA). The purpose of this study was to provide fundamental data regarding the use of PNF exercise among patients with musculoskeletal disease. Methods: Fourteen patients who received TKA were randomly divided into an experimental group (n=7) that took part in PNF exercise and a control group (n=7) that performed general rehabilitation exercise. Both groups performed the respective exercises for 30 minutes, five times a week for 2 weeks. For the measurement of ROM, the range of knee flexion was measured using a clinometer smartphone application. A visual analogue scale (VAS) was used for the measurement of the level of pain. The timed up and go test (TUG) was conducted to measure functional activity. A paired t-test was performed to compare within-group changes before and after the PNF exercise. Differences between the experimental group and control group were analyzed by an independent t-test. For all tests, the level of statistical significance was set at α=0.05. Results: After the exercise, there was a significant within-group change in VAS and TUG scores in the experimental group and control group (p<0.01). There was also a significant between-group difference in VAS and TUG scores after the intervention (p<0.05). Conclusion: General rehabilitation exercise is commonly applied as a treatment for TKA patients and is relatively effective. The application of PNF exercise may be useful in such patients, considering its effects on ROM improvement, pain reduction, and functional enhancement.

          Purpose : The purpose of this study is to find out which method is efficient to enhance the flexibility of lower back between PNF(Proprioceptive Neuromuscular Facilitation), static and dynamic stretching. Methods : Subjects were 30 young people between the ages 17 and 19. They were randomly divided into three groups; static group(n=10) performed a static stretching, dynamic group(n=10) performed a dynamic stretching, and PNF group(n=10) performed a PNF stretching. Intervention was provided 5 days per week for 4 weeks. For each case, Trunk flexion forward, trunk flexion backward, trunk left lateral bending, trunk right lateral bending, trunk flexion forward a measuring instrument and tapeline were performed to measured the flexibility of lower back at different times(before starting the exercise, after 4 weeks). Results : The results of the study reveal that the lower back flexibility was a statistically significant difference in all groups(p<.05). There was statistically significant difference between PNF group and static group, PNF group and dynamic group. Conclusion : The finding indicated that PNF may be preferred technique for improving flexibility, and that flexibility training results in an increased consistency of flexibility scores.

          무릎관절 각도에 따른 한 다리 데드리프트 운동시 뒤넙다리근과 넙다리네갈래근의 근활성도 비교

          문상재,김정욱,박민철 대한고유수용성신경근촉진법학회 2021 PNF and Movement Vol.19 No.1

          Purpose: The purpose of this study was to investigate muscle activity according to knee flexion angle during single-limb-deadlift exercises. Methods: In total, 26 healthy volunteers participated. The single-limb-deadlift consisted of 0°, 15°, and 30° knee joint bending. The electromyography data were collected from the semitendinosus (SM), the biceps femoris (BF), the rectus femoris (RF), the vastus lateralis (VL), and the vastus medialis (VM). In addition, hamstrings and quadriceps (HQ) ratio was measured during the single-limb-deadlift using electromyography. Results: During the single-limb-deadlift, RF, VL, and VM were significantly higher at 30° bending angles compared to muscle activity of 0° and 15° knee-joint bending. The HQ ratio had significant differences in all three knee joint bending angles. In particular, the single-limb-deadlift carried out to a 30° knee-joint bend showed the closest value to 1. Conclusion: The most balanced coactivation ratios were observed during a single-limb-deadlift to a 30° knee-joint bend angle. A single-limb-deadlift at a knee-bend angle of less than 30° could be used as an exercise to prevent ACL injury. It could also be used for post-injury rehabilitation programs by increasing knee-joint stability. .

          Purpose : The purpose of this study was to assess the effects of the lower extremity muscle activity on bridging exercise according to the knee joint angle. Methods : Twenty-five healthy adults volunteered to participate in this study. Subjects were required to complete following four bridging exercises; knee joint flexion $120^{\circ}$, $90^{\circ}$, $60^{\circ}$, $45^{\circ}$. Surface electromyography from selected lower extremity muscles was normalized to maximum voluntary isometric contraction. Muscle activity was measured by QEMG-4 system (LXM 3204, Laxtha Korea). A repeated measures of one-way ANOVA was used to determine the influence of bridging exercise on muscle activity for each muscle and descriptive statistics was used to determine muscle ratio. Results : The biceps femoris of all bridging exercises showed significantly(p<.05). The vastus medialis and lateralis of all bridging exercises showed significant excepted $120^{\circ}$(p<.05). The rectus femoris of all bridging exercises showed no significant. Median of vastus medialis/rectus femoris ratio of $120^{\circ}$ was 2.03, $90^{\circ}$ was 2.16, $60^{\circ}$ was 2.67, $45^{\circ}$ was 4.10. Median of vastus lateralis/rectus femoris ratio of $120^{\circ}$ was 1.70, $90^{\circ}$ was 1.70, $60^{\circ}$ was 2.08, $45^{\circ}$ was 2.58. Median of vastus medialis/vastus lateralis ratio of $120^{\circ}$ was 1.26, $90^{\circ}$ was 1.50, $60^{\circ}$ was 1.52, $45^{\circ}$ was 1.47.
