Hand Strength

The purpose of this study is to evaluate the performance of the Dinomometer and establish normative data to inform clinical standards and benchmarks for therapeutic practice. This is a cross-sectional study designed to collect normative grip strength data from a large sample of the general population in Minnesota. Participants will primarily be recruited from attendees of the Minnesota State Fair. Grip strength will be measured using the Dinomometer, a non-invasive handheld grip strength measurement device. The study should take approximately 10-15 minutes to complete for each participant including enrollment and completion of study procedures. Follow-up is not required.

The goal of this observational study is to learn how a pregnant woman's physical fitness and emotional well-being can help predict the type of birth she will have (such as a natural vaginal birth versus a cesarean section or a birth requiring medical assistance). The study focuses on pregnant women in their third trimester (after 28 weeks of pregnancy). The main questions the study aims to answer are: * Can simple tests of physical strength and questions about emotions (like fear of childbirth) help health professionals predict if a birth might have complications or lack of progress? * Do a woman's physical activity and confidence levels during pregnancy affect her ability to successfully breastfeed her baby for up to 6 months? Participants will be asked to: * Perform two simple physical tests during a clinic visit: a hand-grip test (dynamometry test) and a test to see how many times they can stand up from a chair in 30 seconds (Chair Stand Test, CST). * Complete surveys about their daily physical activity (PPAQ-S), their feelings and fears regarding childbirth (WDEQ-A), and how confident they feel about handling the final stage of birth and the pushing phase (CBSEI-16). * Answer brief follow-up phone calls one month and six months after the birth to talk about how breastfeeding is going.
