Purpose: The purpose of this study was to investigate the effects of pelvic floor muscle exercise using electric stimulation and biofeedback on maximum pressure of vaginal contraction, vaginal contraction duration and sexual function in women who have had vaginal rejuvenation. Methods: The research design was a non-equivalent control group non-synchronized design study. Participants in this study were women who had vaginal rejuvenation at C obstetrics and gynecology hospital. The 15 participants in the experimental group were given pelvic floor muscle exercise using electric stimulation and biofeedback and the 15 participants in the control group received self pelvic floor muscle exercise. Results: For maximum pressure of vaginal contraction, the experimental group showed a statistically significant increase compared to than the control group (t=5.96, p <.001). For vaginal contraction duration, the experimental group also showed a statistically significant increase compared to the control group (t=3.23, p =.003). For women' s sexual function, the experimental group showed a significant increase when compared to the control group in total sexual function scores (t=3.41, p =.002). Conclusion: The results indicate that pelvic floor muscle exercise with electric stimulation and biofeedback after vaginal rejuvenation is effective in strengthening vaginal contraction pressure, vaginal contraction and that it also positively functions to increase women's sexual function.

PURPOSE: This study aimed to examine the effects of lumbar stabilization exercise during abdominal hollowing with conscious contraction of the pelvic floor muscles on trunk muscle in healthy twenties subjects. METHODS: The participants were randomly allocated to an experimental group (n=15) and a control group (n=15). The experimental group received lumbar stabilization exercise combined with conscious contraction of the pelvic floor muscles during abdominal hollowing. The control group received lumbar stabilization exercise with abdominal hollowing. Both groups trained with the respective exercise for 30 minutes a day, 3 times a week for 6 weeks. Muscle activation of the external oblique and erector spinae muscles, thickness of the transversus abdominis and multifidus, and contraction holding time of tranversus abdominis were measured before and after exercise. RESULTS: Activations of both the external oblique muscles were significantly decreased, and thickness of both the transversus abdominis and multifidus muscles, and contraction holding time of the transversus abdominis muscle were significantly increased in the experimental group (p<.05). The thickness of the left transversus abdominis and right multifidus muscles, and the contraction holding time of the transversus abdominis muscle significantly increased in the control group (p<.05). On comparing both groups, the activations of both external oblique muscles were significantly reduced and the contraction holding time of the transversus abdominis muscle was significantly increased in the experimental group (p<.05). CONCLUSION: These results suggest that lumbar stabilization exercise by abdominal hollowing and conscious contraction of the pelvic floor muscles is suitable and efficient for healthy twenties subjects.

PURPOSE: This study was designed to investigate the effects of keeping contraction of abdominal and pelvic floor muscles on 3D pelvic stability in individuals with nonspecific chronic low back pain (CLBP) during normal speed walking. METHODS: The subjects were 20 adults with CLBP deformity and had moderate pain intensity of the visual analog scale. A three-dimensional camera capture system was used to collect kinematic pelvic motion data with and without contraction of the abdominal and pelvic floor muscles during gait. The subjects were asked to walk on a walkway in the lab room and they were attached 40 reflective markers to their pelvic segment and lower extremities. A Visual3D Professional V6 program and Vicon Nexus software were used to analyze 3D pelvic kinematic data. RESULTS: There were significant differences between with and without contraction of the abdominal and pelvic floor muscles of the pelvic depression and the total pelvic motion in coronal plane during gait (p < .05). However, there were no significant differences in any of the maximal motion of the pelvic segment in sagittal and transverse motion plane according to the different muscle contraction conditions (p > .05). CONCLUSION: The results of this study suggest that maintaining co-contraction of the abdominal and pelvic floor muscles in individuals with CLBP increased pelvic stability and contributed to preventing excessive pelvic movements during gait.

This study was designed to evaluate the effect of pelvic floor muscle strengthening exercise treatment program for the older women with stress incontinence. The researcher developed 8 weeks training program which was implemented at a social welfare center in Seoul. The exercise method followed the Kegel criteria. Verbal instructions were given to the subjects. Subjects were confirmed of the exercises and evaluated by description of the exercise method. Fourteen elderly women(mean age 75.7) with stress incontinence participated and completed this program. The training sessions were held twice a week and each session took 45 minutes ; 15 minutes for pelvic floor muscle strengthening program and 30 minutes for other physical therapy. Pelvic floor muscle strengthening exercise program was applied using verbal instruction and practice at social welfare center, twice a week and daily home exercise program were given to each individual. The results were as follows ; 1. There was significant decrease of lower urinary symptoms in the subjects (p = 0.00) 2 But there was no significant change in the sexual matters (p = 0.44) and the life style (p = 0.41) In conclusion, further study with larger sample group is suggested in order to confirm the study result. Because of limited sample size, the study results were not conclusive. But the pelvic floor muscle strengthening exercise treatment program could be a safe and effective program and is suggestive for the community residing older women with stress incontinence as a geriatric physical therapy intervention.

Striated muscle insertions into the skin and mucosa are present in the head, neck, and pelvic floor. We reexamined the histology of these tissues to elucidate their role in transmission of the force. We examined histological sections of 25 human fetuses (gestational ages of ~11-19 weeks and ~26-40 weeks) and 6 cadavers of elderly individuals. Facial muscle insertion or terminal almost always formed as an interdigitation with another muscle or as a circular arrangement in which muscle fiber insertions were sandwiched and mechanically supported by other muscle fibers (like an in-series muscle). Our examination of the face revealed some limited exceptions in which muscle fibers that approached the dermis were always in the nasalis and mentalis muscles, and often in the levator labii superioris alaeque nasi muscle. The buccinator muscle was consistently inserted into the basement membrane of the oral mucosa. Parts of the uvulae muscle in the soft palate and of the intrinsic vertical muscle of the tongue were likely to direct toward the mucosa. In contrast, the pelvic floor did not contain striated muscle fibers that were directed toward the skin or mucosa. Although 'cutaneous muscle' is a common term, the actual insertion of a muscle into the skin or mucosa seemed to be very rare. Instead, superficial muscle insertion often consisted of interdigitated muscle bundles that had different functional vectors. In this case, the terminal of one muscle bundle was sandwiched and fixed mechanically by other bundles.

Purpose : Kegel exercises reported that it is effective in managing stress-related or complex urinary incontinence through contraction and relaxation of the pelvic floor muscles. In many previous studies, it was confirmed that Kegel exercise is involved in respiration as well as urinary system diseases. However, there is a lack of research on the effect of pelvic setting when performing Kegel exercises. Therefore, this study was conducted to investigate the effect on maximum voluntary ventilation (MVV) and abdominal muscle thickness through Kegel exercise after lumbar-pelvic motor control using pressure biofeedback unit (PBU). Methods : The subjects of this study were 10 healthy female students in their 20s. Subjects measured MVV with a spirometer. In hooklying, external oblique, internal oblique, and transverse abdominis of the dominant hand were measured using ultrasound. The measured value was an average of three times. After one week of intervention, measurements were made in the same manner. Before Kegel exercise, pelvic setting training was performed using PBU. In hooklying, PBU was placed in the waist and set to 40 mmHg, and it was adjusted to 60 mmHg through pelvic muscle contraction. For Kegel exercise, the pelvis was first set using PBU, and then the pelvic floor muscles were contracted for 8 seconds and relaxed for 8 seconds, 10 times, 1 set, and 3 sets. Results : In MVV, a significant difference was confirmed after exercise than before exercise (p<.05). There was also a significant difference in abdominal muscle thickness before and after exercise (p<.05). Conclusion : Based on the results of this study, Kegel exercise using PBU had an effect on MVV and abdominal muscle thickness. However, since this study was conducted without a control group as a preliminary study, additional research should be conducted to supplement this.

PURPOSE: This study aimed to identify differences in the thickness of the transverse abdominis (TrA) and pelvic floor muscles (PFM) between those with (LBP) and without low back pain (non-LBP). The standardized methods of contraction for the TrA and PFM were used to perform the abdominal draw-in maneuver (ADIM) and pelvic floor muscle contraction (PFC), respectively. METHODS: This study included 27 young men and women, who were verbally instructed regarding the maneuvers (LBP, n=14; non-LBP, n=13). For all subjects, TrA and PFM thickness were evaluated by ultrasonography during ADIM and PFC. RESULTS: The results of this study showed that TrA thickness increased during ADIM and PFC to a greater degree in the non-LBP group than in the LBP group (p < 0.01). PFM thickness increased more during PFC in the non-LBP group than in the LBP group (p < 0.05). Both groups showed greater increases in TrA thickness during ADIM than during PFC (p < 0.01), and greater increases in PFM thickness during PFC than during ADIM (p < 0.05). CONCLUSION: These results suggest that receiving verbal instructions on how to use each muscle for a specific maneuver was more beneficial than other verbal instruction. Further studies are needed determine how our results may be applied beneficially in research on this topic.

Purpose : This study was conducted to determine the effect of intervention using a smartphone application on abdominal muscle thickness and maximum voluntary ventilation when conducting pelvic floor muscle exercise (PFME). Methods : This study was performed on 14 subjects. They were divided into two groups; PFME using smartphone application (n=7), common PFME (n=7). Both of group executed the exercise 5 times a week for 1 weeks. Abdominal muscle thickness was measured using ultrasound. Maximum voluntary ventilation was measured using a spirometer. The smartphone application used the paid version of Kegel trainer. This material was analyzed by the paired t-test to compare differences on each group and the independent t-test to compare between the two groups. Results : The PFME group using the smartphone application showed a significant increase in the transverse abdominis and internal oblique muscles (p<.05). The common PFME group showed a significant increase in the internal oblique muscle (p<.05). There was no significant difference in variation of the muscle thickness between the two groups (p>.05). The PFME group using the smartphone application showed a significant increase in the maximal voluntary ventilation (p<.05). There was no significant difference in variation of the maximal voluntary ventilation between the two groups (p>.05). Conclusion : As a results of this study, PFME using a smartphone application seems to induce voluntary participation of subjects and maintain continuity against time constraints. As a result, it is thought that using a smartphone application when performing PFME is efficient and convenient in terms of research method. However, this study is difficult to generalize due to the small number of subjects and short intervention period. Therefore, additional research should be conducted by modifying and supplementing these limitations.
