“…Although the intervention was based on the social cognitive theory, the stage of motivational readiness for physical activity (an aspect of the transtheoretical model) was assessed because behavior change interventions may improve stage of readiness without a significant improvement in physical activity levels (7,12,28,29). Responses to a previously validated 5-item scale were classified into precontemplation, contemplation, preparation, action, or maintenance stage of readiness and coded as 1 through 5, respectively (30).…”

“…Behavior change interventions are needed to reduce physical inactivity and, fortunately, a cancer diagnosis may be a ''teachable moment'' when patients are more motivated and open to participation in such interventions (6). Multiple randomized trials of physical activity behavior change studies in cancer survivors have been reported with eight focusing on breast cancer, one focusing on prostate cancer, one focusing on endometrial cancer, and four focusing on mixed cancer types (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). It is encouraging that 10 of these studies have shown significant improvements in physical activity, and 2 of the 4 without activity increases reported improvements in exercise stage of change.…”

Purpose: We previously reported the effectiveness of a 12-week physical activity behavior change intervention for breast cancer survivors postintervention with this report, aiming to determine delayed and/or persistent effects 3 months after intervention completion. Methods: Forty-one sedentary women with stage I, II, or IIIA breast cancer currently receiving hormonal therapy were randomly assigned to receive the 12-week Better Exercise Adherence after Treatment for Cancer intervention or usual care. Assessments occurred at baseline, postintervention, and 3 months postintervention.Results: Weekly minutes of greater than or equal to moderate intensity physical activity measured by accelerometer showed a significant group by time interaction (F = 3.51; P = 0.035; between group difference in the mean change from baseline to 3 months postintervention, 100.1 minute, P = 0.012). Significant group by time interactions also showed sustained improvements from baseline to 3 months postintervention in strength (F = 3.82; P = 0.027; between group difference, 11.2 kg; P = 0.026), waist-to-hip ratio (F = 3.36; P = 0.041; between group difference, À0.04; P = 0.094), and social well-being (F = 4.22; P = 0.023; between group difference, 3.9; P = 0.039). A delayed reduction in lower extremity dysfunction 3 months postintervention was noted (F = 3.24; P = 0.045; between group difference in the mean change from postintervention to 3 months followup; P = À7.6; P = 0.015). No group by time effect was noted for fitness, body mass index, percent fat, bone density, total quality of life (Functional Assessment of Cancer Therapy-General), fatigue, endocrine symptoms, cognitive function, or sleep. Conclusions: The intervention resulted in sustained improvements in physical activity, strength, central adiposity, and social well-being with lower extremity function benefits appearing 3 months after intervention completion. Testing translation in a multisite study is warranted.

“…28 Approximately 23 published, randomized trials have examined the effect of exercise after a breast cancer diagnosis on physical and emotional functioning and overall quality of life. [29][30][31][32][33][34][35][36][37][38][39] The majority of these studies have shown that physical activity is safe after a diagnosis of breast cancer and is associated with improvements in physical and emotional quality of life. However, although these findings are positive, most of these studies had methodological limitations.…”

“…6 Several investigators have used these physical performance tests to describe treatment and temporal changes in the physical and functional capacity of patients with specific oncology diagnoses, including lung and breast cancer patients as well as oncology patients receiving palliative care. [7][8][9][10] However, the outcomes reported in these studies vary substantially from the normative values reported by Simmonds. 6 Although these studies demonstrate the clinical utility of this battery of tests, the variance in normative values for these tests that exists across these studies suggests the need to develop reference values based on specific cancer diagnoses.…”

“…[7][8][9][10] Specifically, Basen-Engquist et al 8 reported that breast cancer survivors were fitter than a heterogeneous oncology population, as did Montoya et al 7 for advanced lung cancer patients. Given the complexities of various cancers and the wide variety of adverse effects arising from cancer treatments, differences in functional performance measures should be anticipated.…”

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.
