This study investigates the effects of a physical activity program called STEPS to Enhance Physical Activity on people with multiple myeloma who have undergone a type of stem cell transplant. Multiple myeloma is a cancer that affects plasma cells in the bone marrow. The study aims to see how this program affects tiredness, the ability to do everyday tasks, muscle strength, physical activity levels, and overall quality of life.
Participants in the study will either follow the STEPS program or continue with their usual care. The STEPS program is designed to be a free-living intervention, meaning it can be done in the participants' everyday environments. The study will measure various outcomes like fatigue, functional ability, and muscle strength to understand the benefits of the physical activity program.
- Who can participate: Adults undergoing hematopoietic cell transplantation for multiple myeloma who can understand the study and are able to move around at home can participate. Assistive devices like canes and walkers are allowed.
- Study details: Participants will engage in a physical activity program or continue with usual care. The study will compare the effects of these approaches on fatigue and quality of life. Participants will be monitored for safety and effectiveness of the activities.
