Effects of a physiotherapeutic protocol in cardiorespiratory, muscle strength, aerobic capacity and quality of life after hematopoietic stem cell transplantation

Abstract

Objective: To analyze the effects of hospital cardiorespiratory physical therapy protocol on the functional capacity and quality of life of patients submitted to hematopoietic stem cell transplantation (HSCT). Methods: From January to December 2019, bilateral dynamometry, Manovacuometry and Ventilometry, peak expiratory flow ''Peak Flow'', 6-min walk test (6MWT), SF-36 Quality of Life Questionnaire and Visual Analog Scale (VAS) were applied in patients who have undergone an allogeneic or autologous hematopoietic stem cell transplantation (HSCT), pre-conditioning (initial evaluation) and pre-discharge (final evaluation). The patients were submitted to an intervention protocol, consisting of aerobic training, muscle strengthening and respiratory muscle training, between the two assessments. Results: 29 patients were enrolled in the study and 24 (83%) completed all procedure. Myeloablative and reduced intensity conditioning were performed in 89.6% and 10.4%, respectively; 17 (58%) patients have undergone an autologous HSCT; 10 (35%) identical related allogeneic HSCT, and 2 (7%) haploidentical allogeneic HSCT. The median number of interventions per patient was 3 (1–9). A decreasing in the right and left dynamometry (p ≤ 0.0001 and 0.002, respectively) and, also in the distance covered in the 6MWT (p = 0.004), was observed after HSCT. There was no significant difference in respiratory muscle strength, quality of life and fatigue sensation. Conclusion: Cardiorespiratory rehabilitation can preserve functional capacity and quality of life.
