Breast Cancer
Conditions
Brief summary
This is a transversal monocentric study comparing two groups of women (group 1, patient group : patients who have been treated for a breast cancer with taxane-based chemotherapy ; group 2, control group : healthy volunteers). The aim of this study is to evaluate if a difference exists regarding the maximal isometric muscle strength between group 1 and 2.
Detailed description
All subjects will be evaluated a single time during two hours. For patients from group 1 the evaluation should take place within the two weeks that follow the end of adjuvant treatment. There is no specificity regarding evaluation of volunteers from group 2, their evaluation can take place at any time.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximal isometric muscle strength for knee extensors | At Inclusion | Measured with force sensors. Significant differences between the two groups will be assessed |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants with neuromuscular fatigue | At Inclusion | Assessment using surface electromyography. Significant differences between the two groups will be assessed. |
| Number of Participants with subjective fatigue. | At Inclusion | Questionnaire Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-F) version 4. Significant differences between the two groups will be assessed. |
| Number of Participants with muscle architecture. | At Inclusion | Assessment using muscle ultrasonography. Significant differences between the two groups will be assessed. |
| Number of Participants with body composition. | At Inclusion | Assessment using bio-impedance analysis. Significant differences between the two groups will be assessed. |
