A B S T R A C T PurposePrevious research incorporating yoga (YG) into radiotherapy (XRT) for women with breast cancer finds improved quality of life (QOL). However, shortcomings in this research limit the findings.
Patients and MethodsPatients with stages 0 to III breast cancer were recruited before starting XRT and were randomly assigned to YG (n ϭ 53) or stretching (ST; n ϭ 56) three times a week for 6 weeks during XRT or waitlist (WL; n ϭ 54) control. Self-report measures of QOL (Medical Outcomes Study 36-item short-form survey; primary outcomes), fatigue, depression, and sleep quality, and five saliva samples per day for 3 consecutive days were collected at baseline, end of treatment, and 1, 3, and 6 months later.
ResultsThe YG group had significantly greater increases in physical component scale scores compared with the WL group at 1 and 3 months after XRT (P ϭ .01 and P ϭ .01). At 1, 3, and 6 months, the YG group had greater increases in physical functioning compared with both ST and WL groups (P Ͻ .05), with ST and WL differences at only 3 months (P Ͻ .02). The group differences were similar for general health reports. By the end of XRT, the YG and ST groups also had a reduction in fatigue (P Ͻ .05). There were no group differences for mental health and sleep quality. Cortisol slope was steepest for the YG group compared with the ST and WL groups at the end (P ϭ .023 and P ϭ .008) and 1 month after XRT (P ϭ .05 and P ϭ .04).
ConclusionYG improved QOL and physiological changes associated with XRT beyond the benefits of simple ST exercises, and these benefits appear to have long-term durability.
The high acuity of hematopoietic stem cell transplant (HSCT) recipients receiving glucocorticoid (GC) therapy for acute graft vs. host disease (aGVHD) may limit their adherence to an exercise-based rehabilitation program and hence, slow their recovery. To make this determination, the medical records of 59 subacute outpatient stem cell transplant recipients receiving methylprednisolone (MP) were reviewed for demographic, anthropometric and medical information. Performance on the repeated sit-to-stand, 50-ft walk and 6-min walk tests were determined before and after completing a 4-week progressive exercise rehabilitation program and outcomes were compared by a paired t-test (P < 0.05). Thirty-two patients (54%) finished a treatment plan (adherent group), completing 80% of the prescribed sessions and were reevaluated. Twenty-seven patients (46%) did not complete the rehabilitation program (nonadherent group), primarily because of readmission to the hospital (18 patients, 62%). The adherent group did not significantly improve their physical performance (p > 0.05). However, a subgroup of 40% of these patients did experience clinically significant improvements in their physical performance.These findings 1) support the feasibility of having HSCT recipients receiving GC therapy to participate in an exercise-based rehabilitation program and 2) suggest that to do so can result in clinically significant improvements in functional capacity.
This study assessed the functional capacity of sub-acute SCT recipients using validated physical performance tests, including 6-min walk distance, repeated sit-to-stand time and 50-ft walk time, and compared these outcomes with those reported for a heterogeneous oncology population. The medical records of 80 consecutive sub-acute SCT recipients not receiving corticosteroids were retrospectively reviewed for demographic, medical and anthropometric information, and outcomes for these physical performance tests administered at the time of initial physiotherapy evaluation. Measures of central tendency, 95% confidence intervals, unpaired t-tests and correlation coefficients were calculated using a SPSS statistical package. SCT recipients completed the 50-ft walk in 10.66 ± 4.43 s, repeated sit-to-stand trial in 4.16 ± 1.82 s and walked 400.2 m in 6 min. For the timed tests, SCT recipients were approximately twice as fast as a heterogeneous group of oncology patients and walked approximately 50% further in 6 min. No overlap in the 95% confidence intervals for the two groups was observed for any of the tests. These results (1) suggest that reference values describing the functional capacity of a heterogeneous oncology population underestimate the functional capacity of SCT recipients and (2) provide clinically useful reference values for assessing functional capacity of sub-acute SCT recipients referred for physiotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
