Feasibility of a Co-designed Mobility Intervention After Hip Fracture Surgery

Inclusion Criteria: * Age ≥ 60 years. * Admitted to one of the two acute orthopedic wards at Copenhagen University Hospital Hvidovre (CUHH) following hip fracture surgery. * Pre-fracture Cumulated Ambulation Score (CAS) (by recall) ≥ 3 points, indicating independence or assisted independence in basic mobility activities such as bed transfer, chair transfer, and indoor walking. * Participants may be included if they are able to provide informed consent independently or if informed consent is obtained from a legally authorized proxy (e.g., caregiver or close relative) in cases of cognitive impairment. This applies to both Danish- and non-Danish speaking patients. Non-Danish speakers may be included with support from translated study materials and assistance from relatives or interpreters, where appropriate. * Inclusion the latest on postoperative day three. Exclusion Criteria: * Non-ambulatory before the fracture, e.g. permanently bedbound or wheelchair-dependent. * Terminal illness with limited expected survival. * Post-operative weight-bearing restrictions precluding mobility activities. * Multiple fractures or suspected pathological fractures (e.g. related to malignancy). * Clinically unstable or presenting conditions in which early mobilization is contraindicated. * Patients who previously participated in HIP-ME-UP Study 4, ensuring that recipients in Study 6 have not been prior HIP-ME-UP study participants or patient partners.
