OBJECTIVES: Considering the advances in functional rehabilitation in recent decades, therapist-oriented home rehabilitation (TOHR) has been increasingly used in the field of physical therapy because it increases patient compliance and reduces health system costs. The objective of this study was to investigate the effects of TOHR on functional capacity, muscle strength, and quality of life (QoL) in adults with sickle cell anemia (SCA). METHODS: Forty adults with SCA underwent manually guided TOHR for 12 weeks. Before and at the end of training, the following variables were assessed in the participants: distance covered in the 6-min walk test (6MWD); maximal inspiratory pressure (MIP); maximal expiratory pressure (MEP); handgrip strength (HGS); quadriceps strength (QS); and QoL using the Short Form-36 physical component summary (SF-36PCS) and the Short Form-36 mental component summary (SF-36MCS). RESULTS: After TOHR, significant increases were observed in the mean values for the 6MWD, MIP, MEP, HGS, QS, and SF-36PCS and SF-36MCS scores. The relative delta between the pre- and post-TOHR 6MWDs correlated significantly with the relative deltas of MIP (rs = 0.640, p < 0.0001), MEP (rs = 0.587, p < 0.0001), HGS (rs = 0.360, p = 0.022), and QS (rs = 0.351, p = 0.026). When the participants were separated according to their use of hydroxyurea, significant increases were observed in the relative deltas of the 6MWD, MIP and MEP values. CONCLUSIONS: This study shows that TOHR can potentially increase functional capacity, muscle strength, and QoL in adults with SCA. Furthermore, there appears to be a relationship between 6MWD gains and muscle strength gains with TOHR.Trial registration: ClinicalTrials.gov identifier: NCT04705792.
