Study aim: To compare the effects of yoga therapy, transcutaneous tibial nerve stimulation (TTNS), and combined yoga therapy and TTNS on stress, anxiety, depression, quality of life, pelvic floor muscle function, and urinary incontinence symptoms in women with urgency urinary incontinence Design: Randomized, single-blind, parallel-group trial (no control), 70 women with urgency urinary incontinence. Block randomization (size 6) via randomization.com. Settings and conduct: Participants will be identified via the Physiotherapy Clinic, School of Rehabilitation, Shahid Beheshti University, and enrolled after informed consent. Allocation to three groups will use block randomization with sealed-envelope concealment. Twelve sessions (3x/week) will be held at Day Hospital and the Zafar Street yoga center. Pre- and post-intervention assessments will occur in sessions separate from treatment, using coded forms. Full participant blinding is not feasible given the observable nature of the interventions. Participants/Inclusion and exclusion criteria: Women aged 25 to 65 years with urgency urinary incontinence for 6 months to 1 year, confirmed by a specialist physician and a symptom questionnaire, with no regular pelvic floor exercise or yoga in the preceding 6 months; exclusions: pregnancy, pure or predominant stress incontinence, pelvic organ prolapse grade 2 or higher, absent pelvic floor muscle contraction, cognitive impairment, cardiac pacemaker or electrical implant, inability to attend sessions regularly, recent urinary tract infection or pelvic, lumbar, or lower limb surgery, and neurological or sensory disorders of the lower limbs Intervention groups: Yoga therapy, TTNS, combined yoga therapy and TTN Main outcome variables: Urgency urinary incontinence symptoms, pelvic floor muscle function, stress, anxiety, depression, quality of life
