About this trial
The incidence of hip fractures in France is 50,000 cases per year among women and 16,000 among men, with a 1-year mortality rate of 20-24%. After a fracture, 10-30% of patients become functionally dependent. The increasing aging of the population and the rise in dependency are likely to worsen the situation of older patients in hospital settings.
Several tools are available to assess functional independence, including the New Mobility Score (NMS), which evaluates mobility through three domains: mobility indoors, mobility outdoors, and shopping activities. The NMS has shown good performance in predicting patient mortality and functional recovery, and its use is recommended in clinical practice. However, the French version of the NMS has not yet been validated.
The French validation of the NMS is important to facilitate its implementation in clinical practice and research, particularly because of its simplicity and the need for rapid assessment tools for healthcare professionals. A French version of the NMS has been translated, and the MOB-SCORE study aims to assess its reliability and validity among healthcare professionals caring for patients with hip fractures.

Trial outcomes
Primary outcomes
1
Inter-rater reliability of the New Mobility Score (NMS)
The New Mobility Score (NMS) assesses mobility in three domains (indoors, outdoors, and while shopping). For each domain, a score ranging from 0 (unable to perform the task) to 3 (able to perform the task independently) is assigned, with a total score ranging from 0 to 9. A score of ≤6 indicates functional impairment, whereas a score of \>6 indicates a high pre-fracture level of mobility in patients with hip fracture. The NMS will be rated by a physiotherapist and an adapted physical activity (APA) instructor.

Convergent validity of the New Mobility Score (NMS) with other functional independence scales, cognitive status and age.
Correlation between the New Mobility Score (NMS) and: * Measure of Functional Independence (MIF): 18 items assessing 6 functional domains. Each item is scored from 1 (total assistance) to 7 (complete independence). The total score ranges from 18 to 126. * Cumulated Ambulation Score (CAS): independence in 3 activities (getting in and out of bed, sitting down and rising from a chair, walking ability). Each activity is scored on a scale from 0 (unable despite human assistance) to 2 (able without human assistance), with a total score ranging from 0 to 6 (6 indicating independent ambulation). * Mini-Mental State Examination (MMSE): 30 questions divided into 6 categories. For each question, a correct answer scores 1 point (0 otherwise), with a total score ranging from 0 to 30. * Age
