Purpose : Dysmenorrhea can be caused by misalignment of the pelvis. Since pilates stabilization exercise is a methods that affects pelvic alignment by inducing contraction of abdominal muscles, the purpose of this study is to determine whether dysmenorrhea is reduced when pilates stabilization exercise is applied. Methods : 47 dysmenorrhea patients were randomly divided into experimental (n=23) and control (n=24) groups. The experimental group performed pilates stabilization exercise three times a week for 12 weeks, and the control group did not perform any intervention. Abdominal muscle thickness, lumbar pelvic alignment, and dysmenorrhea were measured before intervention, 6 weeks, and 12 weeks after intervention to determine the mean change over time and the effect of group and factor interactions (repeated measured ANOVA and contrast test for each period). Results : In the experimental group, the thickness of the transverse abdominis, internal oblique, and external oblique muscles were increased significantly by group and period (p<.05). The pelvic torsion, lordosis and dysmenorrhea were also significantly decreased by group and period. But the control group did not change significantly in any of the variables. Conclusion : Applying pilates stabilization exercise to women with dysmenorrhea may be an effective intervention that contributes to relieving dysmenorrhea by correcting the stability and alignment of the lumbar pelvis.

Background: Static hamstring stretching exercises have been widely used to improve flexibility of the hamstring muscles. However, few studies have examined the influence of standing static hamstring stretching (e.g., jack-knife stretching) on movements of the lumbopelvic-hip complex. Objectives: To examine the short-term effects of jack-knife stretching on movements of the lumbopelvic-hip complex. Design: Case series. Methods: Fourteen participants with hamstring tightness (8 male, 6 female) were recruited. Participants performed jack-knife stretching for 150 s. Before and after stretching, participants performed the finger-to-floor distance (FFD), sit and reach (SRT), active knee extension (AKE), passive straight leg raising (PSLA), and active straight leg raising (ASLR) tests as well as pelvic tilt while standing to identify the effects of stretching. Results: There were significant improvements in the FFD, SRT, AKE, PSLA, and ASLR tests after stretching. However, pelvic tilt angle while standing did not significantly change. Conclusion: Jack-knife stretching can be a useful exercise to improve flexibility of the hamstring muscles, but not pelvic alignment while standing.

Background: High-heeled shoes can change spinal alignment and feet movement, which leads to muscle fatigue and discomfort in lumbopelvic region, legs, and feet while walking. Objects: This study aimed to identify the effects of different shoe heel heights on the walking velocity and electromyographic (EMG) activities of the lower leg muscles during short- and long-distance walking in young females. Methods: Fifteen young females were recruited in this study. The experiments were performed with the following two different shoe heel heights: 0 cm and 7 cm. All participants underwent an electromyographic procedure to measure the activities and fatigue levels of the tibialis anterior (TA), medial gastrocnemius (MG), rectus femoris (RF), and hamstring muscles with each heel height during both short- and long-distance walking. The walking velocities were measured using the short-distance (10-m walk) and long-distance (6-min walk) walking tests. Results: Significant interaction effects were found between heel height and walking distance conditions for the EMG activities and fatigue levels of TA and MG muscles, and walking velocity (p<.05). The walking velocity and activities of the TA, MG, and RF muscles appeared to be significantly different between the 0 cm and 7 cm heel heights during both short- and long-distance walking (p<.05). Significant difference in the fatigue level of the MG muscle were found between the 0 cm and 7 cm heel heights during long-distance walking. In addition, walking velocity and the fatigue level of the MG muscle at the 7 cm heel height revealed significant differences in the comparison of short- and long-distance walking (p<.05). Conclusion: These findings indicate that higher shoe heel height leads to a decrease in the walking velocity and an increase in the activity and fatigue level of the lower leg muscles, particularly during long-distance walking.

본 연구의 목적은 젊은 여성을 대상으로 구두 굽 높이에 따라 한다리 서기 자세를 수행하는 동안 배곧은근, 척추세움근, 넙다리곧은근, 뒤넙다리근의 근활성도를 비교하기 위해 연구를 실시하였다. 본 연구는 건강한 20대 여성 20명을 대상으로 0cm, 3cm, 7cm 의 각각 다른 높이의 굽이 있는 구두를 착용하고 안정한 지지면 위에서 정적 균형검사 중 하나인 오른쪽 다리로 한다리 서기를 하는 동안 표면 근전도 장비를 이용하여 오른쪽 배곧은근, 척추세움근, 넙다리곧은근, 뒤넙다리근의 근활성도를 측정하여 비교 분석하였으며 연구 결과 척추세움근과 넙다리곧은근의 근활성도는 굽높이가 증가함에 따라 유의한 증가가 있었고(p<0.05), 배곧은근, 뒤넙다리근의 근활성도는 유의한 차이가 없었다(p>0.05). 구두 굽 높이의 증가는 척추세움근 및 넙다리곧은근의 근활성도를 증가시키며 이로 인한 허리 앞굽음과 골반의 앞쪽 기울임 증가는 신체분절의 위치나 무게 중심의 변화를 일으켜 허리 골반 부위 및 엉덩관절, 무릎관절에 근골격계 통증과 같은 문제를 일으킬 수 있을 것이다.
