Objective: Using biofeedback in instructing pelvic floor muscle (PFM) activation is a great method to provide information on muscle contraction. This study aimed to determine the immediate effectiveness of a mobile game-based instruction with an extracorporeal biofeedback device (EBD) to improve PFM contraction in healthy subjects. Design: Cross-sectional study. Methods: Sixteen healthy subjects (4 men and 12 nulliparous women; age, 31±5 years) were enrolled. The subjects were randomly categorized into two groups, those who were to receive instructions on how to contract the PFM by using the EBD (n=7) and those who were to undergo a transabdominal ultrasonography (TAUS; n=9) with biofeedback. PFM function was measured as the displacement (mm) of PFM elevation by using the TAUS before and after the instructions in each group. Results: The EBD and TAUS groups showed a significant increase in the displacement of PFM elevation after the instructions from 5.93±4.03 mm to 7.62±3.77 mm and from 5.27±3.39 mm to 7.47±2.79 mm, respectively (p<0.05). No significant differences were found between the two groups. Conclusions: The results of this study indicated that instructions for PFM contraction using the EBD and TAUS showed an immediate effect; however, no significant difference in effectiveness was observed between the two instruction methods. Therefore, not only can the TAUS method be used but the EBD method can also be used as a PFM instruction method for noninvasive procedures. However, further studies are needed to demonstrate the effectiveness of training and exercise on larger sample sizes that includes patient populations with PFM dysfunction.

Background: To determine the benefit of pelvic floor muscle exercise (PFME) with visual biofeedback on promoting patient recovery from incontinence, we investigated variables associated with the early restoration of continence for patients who underwent robot-assisted radical prostatectomy (RARP). Methods: Of the 83 patients enrolled, 41 consecutive patients completed PFME (the exercise group), and the other 42 consecutive patients just before the PFME program commenced (the control group). The primary outcome was whether PFME engagement was associated with zero pad continence restoration within 3 months of surgery. Results: Continence restoration percentages (defined as zero pads used per day) at 1, 3, and 6 months after surgery were 49.4%, 77.1%, and 94.0%, respectively. The exercise group achieved significantly higher recovery rates at 1 month (p=0.037), 3 months (p<0.001), and 6 months (p=023). Cox regression analysis demonstrated that a lower Gleason score (<8; hazard ratio [HR], 2.167), lower prostate specific antigen (<20 ng/dL; HR, 2.909), and engagement in PFME (HR, 3.731) were independent predictors of early recovery from postprostatectomy incontinence. Stratification by age showed that those younger than 65 years did not benefit significantly from exercise (log-rank test, p=0.08), but that their elderly counterparts, aged 65-70 years (p=0.007) and >70 years old (p=0.002) benefited significantly. Conclusion: This study suggests that postoperative engagement in PFME with biofeedback speeds up the recovery of continence in elderly patients (≥65 years old) that undergo RARP.

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.

Purpose: The purpose of this study was to identify the effects of Telephone-enforced Preoperative Pelvic Floor Muscle Exercise (TP-PFME) for prostate cancer patients on Urinary Incontinence (UI), Urinary Function (UF) related satisfaction, depression, and Quality of Life (QoL). Methods: A non-equivalent control group non-synchronized design was used with 85 participants. The two experimental groups (EG) began the PFME protocol two weeks prior to surgery. The subjects in the EG I received telephone calls to reinforce the PFME protocol. The comparison group began the PFME protocol after their surgery. Data were analyzed by the SPSS/WIN 21.0 using descriptive statistics, $x^2$ test, One-way ANOVA, Fisher's exact test, and Repeated measures ANOVA. Results: EG I showed higher performance of PFME at one (p=.001) and three months (p=.015) after surgery than the comparison group. Comparison group showed significantly more severe UI at one (p=.002) and three months (p=.006) after surgery and reported lower UF related satisfaction than EG I at one month after surgery (p=.015). Participants in both experimental groups reported higher QoL scores (p=.001) at three months following surgery than those in the comparison group. There were no significant differences in depression among the three groups. Conclusion: The findings from this study suggest that preoperative TP-PFME was effective in decreasing the perceived severity of UI as well as increasing UF related satisfaction and QoL.

Background: The hip muscle plays various roles. Several types of functional performance tests are used for the assessment of patients with various lower extremity injuries. Hip muscle functions are important to test the performance of maintaining the spine, pelvic, and leg during bridging exercise. We designed a novel functional performance test tool, which we named close kinetic chain dynamic lower extremity stability (CKCLE) test to assess hip muscle functions. Objects: The purpose of this study was to determine the relationship between CKCLE test and hip extensor, external rotator, and abductor strengths. Methods: Twenty-two subjects were recruited in the present study (13 males and 9 females). The hip extensor, external rotator, and abductor muscle strengths were measured using a Smart KEMA strength sensor. When the examiner said "Go", the subject performed the CKCLE test by moving one leg from the floor and touching the opposite knee and then return to the floor while maintaining the bridging position. The subjects attempted as many "touches" as possible in the allotted time (20 seconds) during the maximal tests. The correlation between the hip muscle (extensor, external rotator, and abductor) strength of the supporting leg and the number of CKCLE tests performed in 20 seconds was determined using the Pearson correlation. Results: Hip extensor (r = 0.626, p < 0.05), hip external rotator (r = 0.616, p < 0.05), and hip abductor muscle strengths (r = 0.475, p < 0.05) positively correlated with the number of CKCLE tests performed. Conclusion: We designed a CKCLE test and found that performance in the test correlated with hip extensor, external rotator, and abductor muscle strengths. The result suggests that the CKCLE test can be applied as a performance test to assess the functions of the hip extensor, external rotator, and hip abductor muscles.
