Evaluation of mobility recovery after hip fracture: a scoping review of randomized controlled studies

Abstract

Few older adults regain their pre-fracture mobility after a hip fracture. Intervention studies evaluating effects on gait typically use short clinical tests or in-lab parameters that are often limited to gait speed only. Measurements of mobility in daily life settings exist and should be considered to a greater extent than today. Less than half of hip fracture patients regain their pre-fracture mobility. Mobility recovery is closely linked to health status and quality of life, but there is no comprehensive overview of how gait has been evaluated in intervention studies on hip fracture patients. The purpose was to identify what gait parameters have been used in randomized controlled trials to assess intervention effects on older people’s mobility recovery after hip fracture. This scoping review is a secondary paper that identified relevant peer-reviewed and grey literature from 11 databases. After abstract and full-text screening, 24 papers from the original review and 8 from an updated search and manual screening were included. Records were eligible if they included gait parameters in RCTs on hip fracture patients. We included 32 papers from 29 trials (2754 unique participants). Gait parameters were primary endpoint in six studies only. Gait was predominantly evaluated as short walking, with gait speed being most frequently studied. Only five studies reported gait parameters from wearable sensors. Evidence on mobility improvement after interventions in hip fracture patients is largely limited to gait speed as assessed in a controlled setting. The transition from traditional clinical and in-lab to out-of-lab gait assessment is needed to assess effects of interventions on mobility recovery after hip fracture at higher granularity in all aspects of patients’ lives, so that optimal care pathways can be defined.

“…Therefore, people who exhibit these aspects of age-related decline and walk at a fast pace may be at increased risk of falling, especially if they are unable to produce defensive lateral reactions. Furthermore, the evidence regarding mobility improvement in patients with hip fractures after interventions primarily relies on gait speed assessments conducted in controlled settings [16]. To comprehensively understand falls in real-life scenarios after hip fracture, a transition from traditional clinical and in-lab gait assessments to out-of-lab evaluation is essential.…”
