This study was conducted to investigate the effectiveness of pelvic floor muscle exercise using biofeedback and electrical stimulation after normal delivery.

The subjects of this study were 49 (experimental group: 25, control group: 24) postpartum women who passed 6 weeks after normal delivery without complication of pregnancy, delivery and postpartum. The experimental group was applied to the pelvic muscle enforcement program by biofeedback and electrical stimulation for 30 minutes per session, twice a week for 6 weeks, after then self-exercise of pelvic floor muscle was done 50-60 repetition per session, 3 times a day for 6 weeks. Maximum pressure of pelvic floor muscle contraction (MPPFMC), average pressure of pelvic floor muscle contraction (APPFMC), duration time of pelvic floor muscle contraction (DTPFMC) and the subjective lower urinary symptoms were measured by digital perineometer and Bristol Female Urinary Symptom Questionnaire and compared between two groups prior to trial, at the end of treatment and 6 weeks after treatment.

The results of this study indicated that MPPFMC, APPFMC, DTPFMC were significantly increased and subjective lower urinary symptoms were significantly decreased after treatment in the experimental group than in the control group.

This study suggested that the pelvic floor muscle exercise using biofeedback and electrical stimulation might be a safer and more effective program for reinforcing pelvic floor muscle after normal delivery.

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.

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.

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).

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.

This study was to examine effects of muscle electric stimulation on chronic knee pain, activities of daily living, and living satisfaction for Korean elderly women.

The design was a nonequivalent control group pretest-posttest study. Subjects were 60 (experimental: 30, control: 30) elderly women 65 years old or above with good orientation and communication. The experimental treatment was electric stimulation on both thigh quadriceps muscles for 15 minutes per time, 3 times per week, for a total of 12 weeks. Measures were the S-F McGill Pain Questionnaire and Arthritis Impact Measurement Scale for chronic knee pain, activities measurement of daily living for activities of daily living, and living satisfaction measurement for living satisfaction. Data was analyzed through the SPSS Win 12.0.

Chronic knee pain by S-F MPQ (t=43.563, p=.000) and chronic knee pain by AIMS (t=31.364, p=.000) were significantly decreased in the experimental group, and the activities of daily living (t=124.353, p=.000) and living satisfaction (t=71.268, p=.000) were significantly increased in the experimental group for Korean elderly women.

Muscle electrical stimulation decreased chronic knee pain, and increased the activities of daily living and living satisfaction for Korean elderly women. Further studies for muscle electric stimulation need to be done.
