Purpose : This study was conducted to determine the effect of Kegel exercise using a pressure biofeedback unit (PBU) for 2 weeks on maximum voluntary ventilation (MVV) and abdominal muscle thickness based on previous studies. Methods : The subjects of this study were 20 healthy female students in their 20s. Subjects were randomly assigned to two groups. Eleven subjects were assigned to the experimental group (EG) and 9 subjects were assigned to the control group (CG). Subjects measured MVV with a spirometer. In hooklying position, transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) of the dominant side were measured using ultrasound. For the measurement value, the average value of three times was adopted. After 2 weeks of intervention, the measurements were measured in the same way. In the EG, pelvic setting training using PBU was performed before Kegel exercise. The PBU was first placed at the waist in the Kegel exercise position and the starting pressure was set at 40 mmHg and adjusted to 60 mmHg through pelvic floor muscle contraction. After performing pelvic control using PBU, Kegel exercise was performed with 8 seconds of contraction, 8 seconds of relaxation, and 3 sets of 10 reps per set. A significance level of 𝛼=.05 was used to verify statistical significance. Results : In the variable of MVV, a significant increase was confirmed in the EG (p<.05). In the abdominal muscle thickness variable, significant increases were confirmed in IO and TrA in the EG (p<.05). In addition, a significant increase in IO was confirmed in the CG (p<.05). Significant increases in IO and TrA were confirmed between groups (p<.05). Conclusion : Based on the previous study, this study confirmed that Kegel exercise using a PBU had a positive effect on MVV and abdominal muscle thickness based on a 2-week intervention.

본 연구의 목적은 노인 여성의 약화된 천장관절 안정화를 위하여 비탄력 고정식 벨트를 적용하여 균형 능력과 낙상예방에 미치는 영향을 알아보고자 하였다. 노인 여성들은 출산과 폐경으로 천장관절의 약화 및 골반 주위근육들의 약화로 인하여 균형능력의 감소와 낙상위험률이 증가된다. 그러나 이와 관련된 연구는 불충분하다. 연구 대상자들은 실험군과 대조군으로 각각 20명씩 무작위로 배정하였으며, 비탄력 고정식 벨트를 실험군에게 적용한 후 균형 측정기를 사용하여 균형능력과 낙상 위험률을 평가하였다. 또한 비탄력 고정식 벨트를 적용한 실험군에서 하복부근육의 근두께를 초음파기기를 사용하여 실험 전후에 측정하였다. 통계방법은 연구대상자의 일반적 특성을 위하여 독립 t-검정, 균형 및 낙상지수를 위하여 $2{\times}2$ 반복 측정 분산분석 및 근두께를 위하여 짝비교 t-검정을 사용하였다. 두 그룹의 교호작용 효과는 안정성 지수(F1,38=47.24, p=0.001), 퓨리에 지수(F1,38=88.83, p=0.001), 체중분포 지수(F1,38=50.21, p=0.001) 및 낙상 지수(F1,38=21.59, p=0.001)에서 모두 통계적으로 유의하게 나타났다. 또한 비탄력 고정식 벨트를 적용한 결과 실험 후 복횡근(p=0.001)과 내복사근(p=0.001)의 근두께는 통계적으로 유의하게 증가하였다. 노인 여성들의 약화된 천장관절의 강화 및 안정화 방법으로 비탄력 고정식 벨트는 균형 및 낙상 예방에 긍정적이며 용이성, 보편성 및 경제적으로 효과적임을 알 수 있었다.

본 연구에서는 복부 드로잉-인 운동과 함께 골반바닥근운동 적용이 복부 근육 두께에 미치는 영향을 알아보고자 하였다. 건강한 성인 30명이 본 연구에 참여하였다. 대상자들은 복부 드로잉인 운동, 골반바닥근육 운동, 복부드로잉인+골반바닥근육운동의 결합, 세 가지 동작을 수행하였다. 동작을 수행하는 동안 모든 대상자의 배바깥빗근, 배속빗근, 배가로근의 두께가 측정되었다. 각 운동에 따른 근육의 두께 차이를 비교하기 위해 일원배치분산분석을 사용하였다. 사후분석으로는 Bonferroni 검정이 사용되었다. 본 연구 결과에 따르면 배바깥빗근은 골반바닥근육 운동만 적용했을 때보다 두 가지 운동이 결합되었을 때 통계적으로 근육의 두께가 증가하는 것을 발견하였다. 배속빗근과 배가로근의 경우는 골반바닥근육 운동, 복부 드로잉인 운동, 두 가지 운동의 결합 순서로 근육의 두께가 증가하는 것을 발견하였다. 이러한 연구 결과는 임상적으로 체간 안정화에 더 효율적인 운동방법을 제시할 수 있을 것으로 사료된다.

본 연구는 정상 성인 20명을 대상으로 복부 안정화에 영향을 미치는 노르딕 워킹과 파워 워킹을 2주간 집중 시행한 후, 복부중심 근육(배속빗근, 배바깥빗근, 배가로근)의 활성도 및 두께, 그리고 복부 피하지방의 두께 변화를 비교하였다. 연구 결과, 근전도를 이용한 배속빗근과 배바깥빗근의 근활성값은 노르딕 워킹과 파워 워킹군 모두에서 훈련 후 높게 나타났으며, 특히 노르딕 워킹 훈련군의 경우 파워 워킹 훈련군에 비해 통계학적으로 유의하게 높은 근활성도의 변화를 보였다. 초음파를 이용한 배가로근과 배속빗근, 배바깥빗근의 두께는 노르딕 워킹 훈련군과 파워 워킹 훈련군 모두에서 통계학적으로 유의한 증가를 나타내었으나 군간 변화 차이는 없었다. 노르딕 워킹은 스틱을 이용하여 균형 안정감을 제공하며 상지와 하지의 큰 움직임을 통해 복부 안정화를 유도하는 효과적인 훈련방법으로써 다양한 재활운동의 형태로 적용하기에 유용할 것으로 여겨진다.

Purpose : Low back pain (LBP) is reported as a risk of experiencing musculoskeletal disorders due to muscle stiffness and hypokinetics. The lumbar spine in an unstable state causes imbalance and lumbar instability. Therefore, This study examined the effects of lumbar stabilization exercise and self-complex exercise program on pain, function, psychosocial level, static balance ability, and transverse abdominal muscle (TrA) thickness and contraction ratio in patients with lumbar instability. Methods : The design of this is a randomized controlled trial (RCT). Twenty-six LBP patients participated in this study. Screening tests were performed and assigned to the experimental group (n=13) and control group (n=13) using a random allocation program. Both groups underwent a lumbar stabilization exercise program. In addition, the experimental group implemented the self-complex exercise program. All interventions were applied three times per week for four weeks. The quadruple visual analog (QVAS), the Korean version of the Oswestry disability index (K-ODI), Korean version of fear-avoidance belief questionnaire (FABQ), static balance ability, TrA thickness, and contraction ratio were compared to evaluate the effect on intervention. Statistical significance was set at 𝛼=.05. Results : Both groups showed significant differences before and after the intervention in QVAS, K-ODI, FABQ, static balance ability, and TrA thickness in contraction (p<.05). In addition, significant differences in K-ODI and FABQ were observed between the experimental group and control group (p<.05). Conclusion : A lumbar stabilization exercise and self-complex exercise program resulted in reduced dysfunctions, psychosocial stability in patients with lumbar instability. Therefore, Lumbar stabilization exercise and self-complex exercise program for patients with lumbar instability are effective method with clinical significance in improving the function and psychosocial stability.

Purpose : This study was to investigate effects of closed kinetic chain and open kinetic chain exercise on the lumbar stabilizarion. Methods : A total of 30 healthy over 20 years old college students(men = 14, women = 16) who were participated in this. We selected randomly people of CKC, OKC, and control group. For the past four weeks, CKC and OKC group worked out 3 times per week and then we compared within group and between groups on muscle width. Results : 1. The width of internal oblique, transverse abdominis, and multifidus were all significantly increased after four weeks exercise in the CKC group(P<.05). 2. The width of internal oblique, transverse abdominis, and multifidus were all increased after four weeks exercise in the OKC group but transverse abdominis musule only showed significant difference. 3. Difference values between pre-exercise and post-exercise of transverse abdominis and multifidus in the CKC group was significantly high and difference among the groups were significant. Conclusion : Accordingly, lumbar stabilizing exercise was more effective to increase a width of abdominal deep muscles through CKC exercise.

Background: Stress urinary incontinence (SUI) is an involuntary leakage of urine from the urethra when intra-abdominal pressure increases, such as from sneezing, coughing, or physical exertion. It is caused by insufficient strength of the pelvic floor and sphincter muscles, resulting from vaginal delivery, obesity, hard physical work, or aging. The pelvic floor electrical stimulator is a conservative treatment generally used to relieve the symptoms of urinary incontinence. it recommended to applied before surgery is performed. Objects: The purpose of this study was to determine if the transcutaneous electrical stimulation (TCES) would be effective for the physiological symptoms and psychological satisfaction of women with SUI for an 8-weeks intervention. Methods: Easy-K is a specially designed user-friendly TCES. Five female who were diagnosed with SUI by a gynecologist but who did not require surgical intervention were included in this study. Intervention was implemented over an 8-week period. Outcome measures included vaginal ultrasonography, Levator ani muscle (LAM) contraction strength, incontinence quality of life (I-QOL), and female sexual function index (FSFI) questionnaires. Results: The bladder neck position significantly decreased across assessment time. Funneling index and urethral width significantly decreased after 8 weeks of intervention (p<.05). The bladder necksymphyseal distance and posterior rhabdosphincter thickness statistically increased and the anterior rhabdosphincter thickness showed a tendency to increase. All participants demonstrated a significant increase in the LAM contraction score across three assessment times (p<.05). Although the total score of the I-QOL did not show significant improvement, it steadily increased and among I-QOL subscales, only the "avoidance" subscale showed statistical improvements (p<.05). The total score of the FSFI statistically improved and the "desire" score significantly changed (p<.05). Conclusion: The TCES is recommended for women who want to apply conservative treatments before surgery and who have suffered from SUI in aspects of sexual function and quality of life.
