Brief summary
The investigators conducted a prospective, randomized, double-blind, placebo-controlled study based on the placebo technique to evaluate the efficacy of TTNS versus placebo in patients with OAB after stroke. The main questions aimed to be answered are: What are the effects of Trans Tibial Nerve Stimulation (TTNS) on incontinence-related clinical parameters and quality of life in patients with overactive bladder (OAB) after stroke compared to the placebo group? Participants (n:22) with post-stroke AAM who meet the exclusion and inclusion criteria will be divided into 2 groups using a randomization table. The first group will receive TTNS (n:11) and the second group will receive placebo TTNS (n:11). Measurements will be performed twice in total, before treatment and at the end of treatment (4th week).
Interventions
The TTNS will be conducted unilaterally, with the patient in a supine position, using a surface electrode dual stimulation channel stimulation device. Two self-adhesive round surface electrodes will be positioned with the negative electrode 2 cm behind the medial malleolus and the positive electrode 10 cm proximal to it. The ground electrode will be placed on the ipsilateral limb. Channel 1 will provide active stimulation, while channel 2 will remain inactive.
Sham TTNS group will be stimulated using the same electrotherapy device, with patients positioned identically and electrodes placed in the same positions as in the TTNS group. The current characteristics (pulse frequency 20 Hz and pulse width 200 ms) will also remain consistent across both channels. The second channel of the stimulation device will be designated as the channel connected to the patient but without delivering stimulation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Decreased frequency of increased voiding | Change from baseline positive response rate at the 4th week after the treatment | The effectiveness of the treatment is evaluated based on the daily voiding frequency post-treatment compared to the daily voiding frequency pre-treatment. The expected outcome is a reduction in the frequency of increased voiding. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The Quality of Life | Change from baseline the Quality of Life at the 4th week after the treatment | The Quality of Life-Incontinence Impact Questionnaire (IIQ7) will be used to assess specific QoL related to incontinence |
| Barthel Index for Activities of Daily Living (ADL) | Change from baseline Barthel Index for Activities of Daily Living at the 4th week after the treatment | The Barthel Index assesses activities of daily living (ADLs), documenting what a patient does daily without determining capabilities. The 10 items to score are: feeding, bathing, grooming, dressing, bowel control, bladder control, toileting, chair transfer, ambulation, and stair climbing. Scores reflect independence, with lower scores indicating less independence. A score above 60 typically denotes independence. |
| Frequency of voiding | Change from baseline Frequency of voiding, nocturia, number of pads at the 4th week after the treatment | The frequency of voiding used will be calculated from the patient's 3-day voiding frequency. |
| Treatment Satisfaction Level | Change from baseline Treatment Satisfaction Level at the 4th week after the treatment | At the end of the treatment, participants will be asked to evaluate their satisfaction level with the administered treatment using a Likert scale ranging from 1 to 5 (5=very satisfied, 4=satisfied, 3=neither satisfied nor dissatisfied, 2=dissatisfied, 1=very dissatisfied). |
| Cystometric value | Change from baseline Cystometric value at the 4th week after the treatment | Cystometric value are useful in defining the voiding characteristics of patients. |
| The Overactive Bladder Symptom Score (OABSS) | Change from baseline The Overactive Bladder Symptom Score at the 4th week after the treatment | OABSS (Overactive Bladder Symptom Score), four questions assessing daytime frequency (OABSS-1), nocturia frequency (OABSS-2), urgency frequency (OABSS-3), and urgency urinary incontinence (OABSS-4). Severity is rated on a Likert scale from 0-2, 0-3, 0-5, and 0-5, respectively. The total score ranges from 0 to 15, with higher scores indicating more severe symptoms. |
