A multimodal physiotherapy programme plus deep water running for improving cancer-related fatigue and quality of life in breast cancer survivors.

The aim of the study was to assess the feasibility and effectiveness of aquatic-based exercise in the form of deep water running (DWR) as part of a multimodal physiotherapy programme (MMPP) for breast cancer survivors. A controlled clinical trial was conducted in 42 primary breast cancer survivors recruited from community-based Primary Care Centres. Patients in the experimental group received a MMPP incorporating DWR, 3 times a week, for an 8-week period. The control group received a leaflet containing instructions to continue with normal activities. Statistically significant improvements and intergroup effect size were found for the experimental group for Piper Fatigue Scale-Revised total score (d = 0.7, P = 0.001), as well as behavioural/severity (d = 0.6, P = 0.05), affective/meaning (d = 1.0, P = 0.001) and sensory (d = 0.3, P = 0.03) domains. Statistically significant differences between the experimental and control groups were also found for general health (d = 0.5, P < 0.05) and quality of life (d = 1.3, P < 0.05). All participants attended over 80% of sessions, with no major adverse events reported. The results of this study suggest MMPP incorporating DWR decreases cancer-related fatigue and improves general health and quality of life in breast cancer survivors. Further, the high level of adherence and lack of adverse events indicate such a programme is safe and feasible.

Compression use during an exercise intervention and associated changes in breast cancer-related lymphedema.

This study assessed the association between compression use and changes in lymphedema observed in women with breast cancer–related lymphedema who completed a 12‐week exercise intervention.

Exercise barriers self-efficacy: development and validation of a subcale for individuals with cancer-related lymphedema

BackgroundNo tool exists to measure self-efficacy for overcoming lymphedema-related exercise barriers in individuals with cancer-related lymphedema. However, an existing scale measures confidence to overcome general exercise barriers in cancer survivors. Therefore, the purpose of this study was to develop, validate and assess the reliability of a subscale, to be used in conjunction with the general barriers scale, for determining exercise barriers self-efficacy in individuals facing lymphedema-related exercise barriers.MethodsA lymphedema-specific exercise barriers self-efficacy subscale was developed and validated using a cohort of 106 cancer survivors with cancer-related lymphedema, from Brisbane, Australia. An initial ten-item lymphedema-specific barrier subscale was developed and tested, with participant feedback and principal components analysis results used to guide development of the final version. Validity and test-retest reliability analyses were conducted on the final subscale.ResultsThe final lymphedema-specific subscale contained five items. Principal components analysis revealed these items loaded highly (>0.75) on a separate factor when tested with a well-established nine-item general barriers scale. The final five-item subscale demonstrated good construct and criterion validity, high internal consistency (Cronbach’s alpha = 0.93) and test-retest reliability (ICC = 0.67, p < 0.01).ConclusionsA valid and reliable lymphedema-specific subscale has been developed to assess exercise barriers self-efficacy in individuals with cancer-related lymphedema. This scale can be used in conjunction with an existing general exercise barriers scale to enhance exercise adherence in this understudied patient group.
