Overcome, a Program of Therapeutic Exercise and Functional Recovery to Improve the Functional Capacity of Women With Breast Cancer and Bone Metastases

The research to be carried out is aimed at patients with metastatic breast cancer, specifically bone metastases. These patients will be recruited from two hospitals in Granada, provided they meet the established inclusion criteria. With this study, it is pretend to demonstrate the benefits of a program of therapeutic exercise and functional recovery of motor control with ultrasound feedback for the improvement of the functional capacity of the women eligible to participate in the study, as well as a positive impact on the quality of life of the patients other than their survival. The effect of the Overcome program will be compared with the usual treatment in this type of pathology. To do this, a pre-intervention evaluation and another at the end of the evaluation of the variables to be measured, such as functional capacity, will be carried out. In addition other evaluation will be carried out, after 6 months to assess the long-term effects.

In addition to the three main variables such as functional capacity and quality of life, another relationship of secondary variables will be studied, such as physical state, body composition or pain threshold, among others. This study in its entirety will be carried out by the "Oncology Patient Support Unit - Take Care" in the hands of a multidisciplinary team, carrying out the intervention protocolized by physiotherapists and occupational therapists.


Eligibility Criteria:
Inclusion Criteria:

4. ECOG (Eastern Cooperative Oncology Group) ≤ 1.
5. \> 4 weeks from a major surgery and full recovery.

Exclusion Criteria:
