Candidates for hematopoietic stem cell transplantation (HSCT) frequently experience declines in strength, physical function, and quality of life before the procedure. Many also present fatigue, limitations in daily activities, and an increased risk of complications during and after hospitalization. Optimizing physical condition before transplantation may improve post-procedure recovery.
This study will evaluate whether a prehabilitation program improves physical function, frailty, and quality of life in adults preparing for HSCT. The intervention consists of supervised exercise, education, and activities designed to enhance endurance and functional capacity. Although prehabilitation has shown benefits in other oncologic populations, it has been minimally studied in HSCT candidates, and no structured programs have been evaluated in Chile.
A total of 68 adults will be randomly assigned to a prehabilitation group or a usual-care control group. The prehabilitation group will receive a personalized program including aerobic and resistance exercise, stretching, balance training, respiratory exercises, and education on healthy behaviors, delivered through a hybrid model of in-person and remote sessions. Occupational therapy will also be provided to support functional and cognitive abilities. The control group will continue with standard medical care.
Baseline and post-intervention assessments will include measures of strength, frailty, fatigue, balance, cognitive function, daily activities, and quality of life. Post-transplant outcomes such as hospital length of stay, complications, and readmissions within three months will also be recorded. Feasibility, adherence, satisfaction, and adverse events will be evaluated.
Findings from this trial may inform the development of structured prehabilitation programs for HSCT candidates and support the implementation of evidence-based supportive care strategies in hematologic oncology.
