We're looking for women aged 60 or older who have UI and could be at some risk of falling. To determine fall risk, we'll ask if they've fallen in the past year if they feel unsteady when standing or walking, or if they worry about falling. If they meet these criteria and agree to participate, they'll be randomly assigned to one of three treatment groups.

We're comparing three treatments :

1. Pelvic Floor Muscle Training: A 12-week program with six visits to a female pelvic health physical therapist.
2. Mirabegron (Myrbetriq): A daily medication taken for 12 weeks.
3. Trospium XL: A once-daily extended-release medication taken for 12 weeks.

Participants will be assessed at the beginning of the study, at 12 weeks, and 6 months. We'll cover the cost of the treatment, and participants will be compensated.

We are looking for Women who are:

• Aged 60 or older,
• Experience urgency UI or overactive bladder, and
• Are willing to answer a few questions about their fall risk
