Clinical Efficacy of Exoskeleton Robot-Assisted Rehabilitation on Lower Limb Functional Recovery in Elderly Patients With Hip Fracture

Inclusion Criteria: * Aged 65 years or older, regardless of gender. * Diagnosed with a unilateral hip fracture resulting from low-energy trauma by imaging (X-ray/CT), and having undergone surgical treatment (internal fixation or arthroplasty). * The participant or their legal guardian understands and agrees to participate in the clinical trial and is willing to provide voluntary written informed consent. Exclusion Criteria: * Life expectancy of less than 6 months. * History of neurological disorders such as prior stroke, spinal cord injury, Parkinson's disease, or myasthenia gravis. * Severe joint contractures, deformities, or heterotopic ossification in the lower limbs that would prevent proper device fitting. * Body weight exceeding the device's maximum load capacity (\>100 kg). * Height outside the adjustable range of the device. * Presence of a pathological fracture or multiple fragility fractures. * Presence of severe osteoarthritis or trauma in the contralateral lower limb that significantly impairs function. * Comorbidities including active malignancy or systemic infection. * Comorbidities such as thromboembolic disease in the lower limbs, pneumonia, or pressure injuries (bedsores). * Comorbidities affecting rehabilitation capacity, including unstable angina, heart failure, severe sequelae of stroke, severe chronic obstructive pulmonary disease (COPD), or severe hepatic/renal dysfunction. * Poor compliance, cognitive impairment preventing cooperation, or diagnosed p…
