Triaxial Accelerometry Study

This study looks at how physical activity levels are in the long term after hip surgery. Arthritis can make everyday movement difficult, and hip replacement surgeries-such as total hip arthroplasty (THA) and hip resurfacing-help reduce pain and improve function. However, it is not clear how these surgeries affect long-term physical activity. To learn more, researchers are following up with patients who had one of these surgeries 15 years ago. Participants will wear two small activity-tracking devices (accelerometers): one on their wrist for 10 days and one on their thigh for 48 hours. These devices will measure how much and how intensely they move. Participants will also complete short physical activity questionnaires. By comparing activity levels between the two types of hip surgery, the study aims to understand their long-term effects on mobility and health. The results could help doctors improve treatment and recovery plans for future patients. All data will be kept private, and participation is voluntary.

Physical Activity: Feasibility Study

The Physical Activity Self-efficacy (PAS) intervention is a web-based behavioral intervention newly developed to promote physical activity in adults with obesity. The conceptual framework for the PAS intervention is based on self-efficacy theory. The objective of this study is to investigate the feasibility and acceptability of implementing the PAS online intervention for adults with obesity recruited from a local weight management center in the United States of America (USA). The study design is a prospective, double-blind, parallel group randomized pilot trial. Thirty participants will be randomly assigned to the PAS group or usual care group to achieve a 1:1 group assignment. Recruitment of participants is scheduled to begin in January 2024 or earlier at a local weight management center within a private healthcare system in the USA. There are five eligibility criteria for participation in this study (e.g., a body mass index ≥ 25.00 kg/m2). Eligibility verification and data collection will be conducted online. Three waves of data collection will take up to 14 weeks depending on participants' progress in the study. Instruments designed to measure demographic information, anthropometric characteristics, self-efficacy, and acceptability will be included in the survey battery. A research-grade accelerometer will be used to measure free-living physical activity objectively. Data will be analyzed using descriptive statistics and inferential statistical models under an intention-to-treat approach. This study will be sponsored by the Transdisciplinary Areas of Excellence Seed Grant Program from Binghamton University.
