Test Device	Yōni.Fit Test Device	Yōni.Fit Test Device

Primary Outcome Measures

Name	Time	Method
Responder rate at Day 21	21 Days	Responder rate at Day 21, where responder is defined as a subject who has at least 50% reduction in mean 12-hour pad weight test through assessment period of treatment phase (the last 7 days of 14-day device usage period), when compared to the mean pad weight test during the 7-day baseline phase

Secondary Outcome Measures

Name	Time	Method
Percent Change in mean pad weight	7 Days, 14 Days	Percent change in mean pad weight during assessment period of treatment phase (the last 7 days of 14-day device usage period), from the mean pad weight during the 7-day baseline phase
Percent change in the frequency of SUI events per the patient diary	7 Days, 14 Days	Percent change in the frequency of SUI events per the patient diary, defined as average number of incontinence episodes per 12 hours during assessment period of treatment phase (the last 7 days of 14-day device usage period), from the average of baseline phase
Responder rate for frequency of SUI events per the patient diary at Day 21,	21 Days	Where responder is defined as a subject who has at least 50% reduction in the number of incontinence episodes per day during the last 7 days of
Percent change in Incontinence Impact Questionnaire (IIQ-7) score	21 Days	7 questions about how urinary incontinence has affected a subjects life. Questions cover physical activity, travel, social relationships and emotional health. The questionnaire asks whether the subjects life has been greatly affected, moderately, slightly or not affected at all.
Percent change in Patient Global Impression of Change (PGIC) score	21 Days	It gives a patient reported assessment of change after intervention. The higher the score, the greater the severity (1 being "very much improved"; 7 "very much worse").
Percent change in Incontinence-Quality of Life (I-QOL) Assessment Questionnaire	21 Days	The I -QOL consists of 22 items, all of which use a five - point ordinal response scale in which 1 = extremely, 2 = quite a bit, 3 = moderately, 4 = a little, and 5 = not at all. The 22 items can be further grouped into 3 sub-scales: Avoidance and Limiting Behaviour (8 ite ms), Psychosocial Impacts (9 items), and Social Embarrassment (5 items). The total I -QOL and 3 sub scale scores are calculated by summing the unweighted item score and transforming them to a 100 point scale where 0 = mo st severe, and 100 = no problem .
Ease of use per the USE Questionnaire: Usefulness, Satisfaction, and Ease of Use	21 Days	The USE questionnaire is meant to be used to assess the Subjective reactions to the usability of the Yōni.Fit ® device. The "Usefulness" section of the questionnaire consists of 19 questions regarding usability of the device scaled from 1- "strongly disagree" to 7- "strongly agree."
Ease of use per the USE Questionnaire: Satisfaction	21 Days	The USE questionnaire is meant to be used to assess the Subjective reactions to the usability of the Yōni.Fit ® device. The "Usefulness" section of the questionnaire consists of 7 questions regarding Satisfaction with the device scaled from 1-"strongly disagree" to 7-"Strongly Agree."
Ease of use per the USE Questionnaire:Ease of Use	21 Days	The USE questionnaire is meant to be used to assess the Subjective reactions to the usability of the Yōni.Fit ® device. The "Usefulness" section of the questionnaire consists of 11 questions regarding Ease of Use with the device scaled from 1-"strongly disagree" to 7-"Strongly Agree."
