METHODS: In this controlled clinical trial, we compare pre-transplantation exercise to no exercise in the waiting period for an allogeneic of autologous HSCT. The supervised individually tailored exercise program (4-6 weeks) consisted of aerobic endurance, muscle strength, and relaxation exercises, administered twice a week in the period prior to HSCT. Feasibility was determined based on inclusion rate, attrition rate, adherence to intervention, safety, and satisfaction (0-10). Preliminary effectiveness was determined primarily by self-perceived physical functioning, quality of life (QOL), and fatigue. Secondary outcomes were global perceived effect (GPE), blood counts, hospital stay, and physical fitness. RESULTS: Forty-six patients were eligible, of whom 29 (69%) participated: 14 in the intervention group and 15 in the control group. The adherence rate to training was 69%. No adverse events or injuries occurred. Satisfaction of training conditions was high (mean 9.2 ±1.3). Positive (follow-up) trends in favor of the intervention group were found for self-perceived physical functioning, QOL, fatigue, GPE, blood counts, and hospital stay. CONCLUSION: Exercise prior to HSCT is safe and feasible, and positive trends suggest favorable preliminary effectiveness. Adherence to the exercise program needs to be optimized in a future trial.
2013, Article / Letter to editor (Physical Therapy, vol. 93, iss. 4, (2013), pp. 514-528)BACKGROUND: The treatment-related burden for patients undergoing hematopoietic stem cell transplantation (HSCT) may be relieved by physical exercises. PURPOSE: The purpose of this study was to summarize and analyze the evidence provided by randomized controlled trials (RCTs) on physical exercise interventions among patients with cancer undergoing HSCT. DATA SOURCES: PubMed, CINAHL, EMBASE, the Cochrane Library, and PEDro were searched for relevant RCTs up to October 1, 2011. STUDY SELECTION: Two reviewers screened articles on inclusion criteria and indentified relevant RCTs. DATA EXTRACTION: Two authors assessed the selected articles for risk of bias. Data extraction was performed by 1 reviewer. Meta-analyses were undertaken to estimate the outcomes quality of life (QOL), psychological well-being and distress, and fatigue. DATA SYNTHESIS: Eleven studies were included, with study populations consisting of recipients undergoing either an allogeneic or autologous HSCT (n=734). Four studies had low risk of bias. The exercise interventions were performed before, during, and after hospitalization for the HSCT. Different exercise programs on endurance, resistance and/or activities of daily living training, progressive relaxation, and stretching were used. Meta-analyses showed that exercise during hospitalization led to a higher QOL (weighted mean difference=8.72, 95% confidence interval=3.13, 14.31) and less fatigue (standardized mean difference=0.53, 95% confidence interval=0.16, 0.91) in patients with an allogeneic HSCT at the moment of discharge from the hospital. No marked effects were found for psychological well-being and distress. Individual study results suggested significant positive effects on QOL, fatigue, psychological well-being and distress, and physical functioning. LIMITATIONS: Prevalent shortcomings in the included studies were the heterogeneity among studies and the lack of blinding of participants, personnel, and outcome assessment. CONCLUSIONS: The results suggest that recipients of HSCT may benefit from physical exercise.
