Mobility Limitations

This study aims to develop and evaluate a smart nursing AI agent to support health self-management among middle-aged and older patients, and further to examine its effectiveness in home care and health self-management. The goal is to propose innovative strategies for middle-aged and older care that enhance the quality of home care and strengthen patients' health self-management abilities. A randomized controlled trial design will be adopted, with a planned enrollment of 102 participants. Participants will be randomly assigned to either the experimental group or the control group. Regardless of group assignment, their routine medical care will remain unchanged. Both groups will participate in the study for 12 weeks (8 weeks of intervention and 4 weeks of follow-up), with identical frequency and number of follow-ups, interviews, and evaluations. The experimental group will receive an 8 week intervention using the smart nursing AI agent care model, which provides daily interaction, reminder systems, personalized recommendations, activity monitoring, goal setting, motivational support, and health self-management education. The control group will continue with the existing standard health education approach. Data collection will include demographic information, medical history, physiological indicators, functional activity measures (e.g., steps, distance, exercise duration), sarcopenia screening, nutritional assessment, physical activity levels, health self-management ability, health literacy, quality of life, and digital usage behaviors. Statistical analyses will be conducted to evaluate the effectiveness, feasibility, and acceptability of the intervention.

This randomized controlled trial will evaluate the effectiveness of dual-task balance training on balance, mobility, and mental health among traumatic lower-limb prosthesis users in the Gaza Strip. Participants will be randomly assigned to either an experimental group receiving dual-task balance training in addition to standard rehabilitation or a control group receiving standard rehabilitation only. The intervention will be delivered over 6 weeks, with three sessions per week. Balance and mobility will be assessed using the Berg Balance Scale and the Amputee Mobility Predictor with Prosthesis, while mental health will be assessed using the Depression, Anxiety, and Stress Scale-21.

The purpose of this 32-week study is to use an innovative experimental design known as SMART (Sequential Multiple Assignment Randomized Trial), which will allow us to determine the best way to sequence the delivery of teleexercise (referred to as an adaptive intervention), combined with predictive analytics on participant adherence in a stepped program of physical activity interventions. All 257 participants will have access to a library of recorded video exercise content, and a weekly wellness article. Some participants will receive health coaching calls (1st randomization). Analytic data will be used to determine which participants are responding or not responding to the intervention. Participants not responding after 4 weeks will receive either live one-on-one or group exercise training (2nd randomization). After 8 weeks, the participant will receive only pre-recorded exercise content and articles for a 24-week maintenance phase (weeks 9-32). The study outcomes are: The effectiveness of the adaptive interventions; Exploring mediating and moderating variables; Sensitivity analysis of the predictive analytics.

This study will compare two exercise-based rehabilitation programs to improve balance and reduce fall risk in adults aged 45 years and older who have had at least one fall in the past year or have balance problems. Participants will be assigned to one of two groups: (1) a virtual reality (VR) exercise program using the PABLO system, or (2) a traditional physiotherapy program based on the Otago approach. Both programs will include balance training, strength/power exercises, aerobic activity, and flexibility. The program will last 12 weeks, with two supervised sessions per week (about 30 minutes each). Assessments will be completed at the start of the study and again after 12 weeks. The main outcomes include frailty status, number of falls, mobility (Timed Up and Go test), and balance (Berg Balance Scale). Additional outcomes include grip strength, quality of life (SF-12), and program adherence and safety. The study will help determine whether VR-based rehabilitation improves participation and outcomes compared with traditional physiotherapy.
