Approximately one third of the population over the age of 65 falls at least once a year. The risk of falling is in increased in older patients with tumor diseases. In addition to high treatment and care costs for the healthcare system, falls often lead to a decrease of quality of life, a reduction in physical performance and a loss of independence. Despite the high risk, falls in cancer patients have not yet been scientifically investigated in detail. For patients with multiple myeloma in particular, very little data is available on the prevalence, risk factors and effects of falls. In this study, a fall risk assessment is carried out in patients with multiple myeloma. Furthermore, a patient-specific training intervention for fall prevention will be implemented.

The aim of the study is to identify possible fall risk factors in multiple myeloma patients and to establish a structured exercise intervention that minimizes the risk of falls and injuries.

Inclusion Criteria:

• Patients with multiple myeloma requiring therapy (at least 6 months of systemic therapy)
• ECOG status ≤ 3
• Age ≥18 years
• Patients who state that they want to carry out the training program at least 3 times/week and participate in the planned follow-up visits
• Ability to give informed consent
• Written consent to participate in the study
• Sufficient written and spoken German to complete the questionnaire

Exclusion Criteria:

• Any physical or mental limitations that would prevent participation in the training program or the planned follow-up checks.

• questionnaire results collected for each individual
• functional test results collected for each individual
