简要总结
The hypothesis of the present study is low intensity extracorporeal low energy shock wave therapy (LiESWT) can decrease inflammatory disorders, increase pelvic floor blood supply, enhanced bladder stem cell activation, Using LiESWT can decrease bladder overactivity, eliminate urinary incontinence and improve stress urinary incontinence (SUI) and overactive bladder (OAB) symptoms. Therefore improve quality of life and improve social activity.
详细描述
Clinical application of low intensity extracorporeal low energy shock wave therapy (LiESWT) (2000 to 3000 impulses in 0.20-0.25 millijoule/mm2 (mJ/mm2)) initiated wound healing, promoted angiogenesis, reduced the level of oxidative stress, induced the releasing of VEGF, stimulated proliferation and differentiation of stem cells, and resulted in the effect of anti-inflammatory and tissue regeneration. Generally, LiESWT was used clinically to improve tissue regeneration at tendon-bone junctions, ischemic cardiovascular disorders, skin wound healing, chronic injuries of soft tissues and erectile dysfunction.
LiESWT has also been shown to increase vascular endothelial growth factor (VEGF) expression in ischemic tissues in vivo and to promote angiogenesis and functional recovery in models of chronic myocardial ischemia, myocardial infarction, and peripheral artery disease. Importantly, the advantages of LiESWT include therapies without medication or surgery, outpatient therapies, short treatment sessions, no anesthesia required, and non-invasive therapy.
The hypothesis of the present study is LiESWT can decrease inflammatory disorders, increase pelvic floor blood supply, enhanced bladder stem cell activation, Using LiESWT can decrease bladder overactivity, eliminate urinary incontinence and improve stress urinary incontinence (SUI) and overactive bladder (OAB) symptoms. Therefore improve quality of life and improve social activity.

研究组 & 干预措施
LiESWT arm
- For SUI: The LiESWT was applied with 0.25 mJ/mm2 intensity, 3000 pulses of shocks, and frequency of 3 pulses/second, once weekly for 4-weeks (W4) and 8-weeks (W8). Probe be transcutaneous applied to the left and right labia minora of the genital area, and the applicator was gently placed on the middle, the left side and the right side of the labia with 0.25 mJ/mm2 intensity and 1000 pulses of shocks individually.
- For OAB: The LiESWT was applied with 0.25 mJ/mm2 intensity, 3000 pulses of shocks, and frequency of 3 pulses/second, once weekly for 4-weeks (W4) and 8-weeks (W8). Probe be transcutaneous applied to the lower abdomen with two fingers apart from the pubic symphysis, tilting to 45°, and the applicator was gently placed on suprapubic skin area over the bladder dome and bilateral bladder walls with 0.25 mJ/mm2 intensity and 1000 pulses of shocks individually.
