Brief summary
This study is aimed to develop a new therapy based on non-invasive repetitive magnetic stimulation rehabilitation for FI in patients who do not respond to conventional therapies.
Detailed description
AIMS 1) General: to develop a new therapy based on non-invasive repetitive magnetic stimulation rehabilitation for FI in patients who do not respond to conventional therapies. 2) Specific: a) To evaluate the optimal dose of cortical magnetic stimulation (rTMS) and lumbosacral magnetic stimulation (rTLS) in young healthy women for its subsequent application in patients with FI. b) To assess the effect of rTMS and rTLS on continence, clinical severity, and QoL in women with FI. DESIGN: 1. Cross-over clinical trial dose-efficacy study: Evaluation of the dose-efficacy of acute rTMS and rTLS in 30 healthy young women. Frequencies will be evaluated for cortical rTMS (1Hz and 5Hz) and 3 rTLS (1, 5, and 10Hz).
Interventions
rTMS and rTLSMS administered using a Magstim Rapid2 repetitive stimulator at pre-identified hotspots (cortical, lumbar, and sacral regions bilaterally. rTMS delivered with 250 pulses via the same double-cone coil used for the neurophysiological study, at either 1 Hz or 5 Hz. For rTLSMS (lumbar and sacral), 2400 pulses (600 per hotspot) were applied at 1 Hz, 5 Hz, or 10 Hz using a 70mm refrigerated air film coil (Magstim, UK). Each dose and stimulation site (cortical or peripheral) were tested in separate sessions.

Intervention model description
This was a randomized cross-over dose-response study conducted at the GI Motility Unit, Hospital de Mataró (Barcelona, Spain), in healthy young female volunteers aged 18-35 years. Exclusion criteria included pregnancy or potential for pregnancy, presence of a pacemaker, history of epilepsy or neurosurgery, study withdrawal, and poor treatment tolerance.
Eligibility
Inclusion criteria
* no history of FI * Be a woman * capable of understanding and providing informed consent
Exclusion criteria
* pregnancy and the ability to become pregnant * presence of a pacemaker * history of epilepsy or neurosurgery * poor treatment tolerance
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| MEP Latency | Baseline (immediately before stimulation) and immediately after stimulation in each session, across 5 weekly sessions (up to 5 weeks). | Latency from the onset of the stimuli (cortical or lumbosacral) to the first deflection of the MEP waveform. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| MEP amplitude | Baseline (immediately before stimulation) and immediately after stimulation in each session, across 5 weekly sessions (up to 5 weeks). | Amplitude measured peak-to-peak of the MEP waveform. |
