It depends on the device and the problem. The electromagnetic pelvic floor chair, sold as Emsella, contracts the pelvic floor muscles thousands of times per session and has reasonable evidence for improving stress incontinence, the leaking that happens with a cough or a jump. Laser and radio-frequency treatments have mixed evidence: some women report improved dryness, comfort, and sensation, while controlled trials have been less convincing than the marketing, and regulators have cautioned against overstated claims. An honest clinic will distinguish the two.
