With the intensification of population aging, hip fracture, as a common bone disease, is seeing an increasing incidence rate among the elderly population. Traditional rehabilitation training methods can no longer fully meet the functional recovery needs of elderly patients with hip fractures. Due to their wearability and intelligence, exoskeleton robots provide an innovative solution for rehabilitation training. This study aims to explore the application effects of exoskeleton robots in postoperative rehabilitation for elderly patients with hip fractures by utilizing exoskeleton robot-assisted rehabilitation training for elderly hip surgery patients. The focus is on its improvements in motor ability, balance ability, and pain levels, while also assessing its impact on patients' overall quality of life and the prevention of complications.

1. Postural Adaptation Training: With exoskeleton support, the patient transitions from a lying or sitting position to an upright stance and maintains this posture for a prescribed duration. 2. Range of Motion (ROM) and Flexibility Training: The robot guides the patient's lower limbs (hip, knee, and ankle joints) through passive, large-amplitude flexion and extension movements within a safe range. 3. Muscle Reactivation and Low-Intensity Strengthening: With robotic assistance, the patient actively attempts to execute joint flexion and extension movements. The exoskeleton provides adjustable assistance levels proportionate to the patient's muscular capacity.
1. Based on the patient's general condition and baseline status, ankle pumps, and isometric contractions of the quadriceps and gluteus medius will be performed progressively according to current international and domestic rehabilitation guidelines; followed by initiation of knee extension exercises, hip abduction exercises of the affected limb, and bridge exercises; 2. Once the patient's physical capacity has recovered to a relatively stable level, progressive resistance training for the quadriceps, hamstrings, and gluteal muscles will be gradually introduced, along with concurrent strength training for both upper limbs and the unaffected lower limb; 3. Depending on the patient's rehabilitation progress, training in position transfer, standing, and gait will be initiated; traditional physical rehabilitation modalities such as therapeutic cycling, electrical stimulation, and medium-frequency therapy devices may also be incorporated.

Harris Hip Score
Assessed using the Harris Hip Score (HHS), a disease-specific instrument widely used for evaluating outcomes following hip surgery or in hip pathology. The scale assesses the patient across four domains: pain (44 points), function (47 points), range of motion (5 points), and absence of deformity (4 points). The total score ranges from 0 to 100 points. A higher score indicates better hip joint function and less disability. The reported value is the total HHS score (points).
Time frame: 1-month post-intervention (T1), 3-month post-intervention (T2).
Berg Balance Scale
Assessed using the Berg Balance Scale. This scale consists of 14 items that evaluate static and dynamic balance abilities (e.g., standing, turning, picking up objects). Each item is scored from 0 to 4 points. The total score ranges from 0 to 56 points. A higher score indicates better balance function. The reported value is the total scale score (points).
Time frame: 1-month post-intervention (T1), 3-month post-intervention (T2)
Timed Up and Go Test
The time required for the subject to rise from a chair, walk 3 meters, turn around, walk back, and sit down is recorded. The reported value is the time to complete the test (seconds). A shorter time indicates better functional mobility.
Time frame: 1-month post-intervention (T1), 3-month post-intervention (T2).
6-Minute Walk Test
The maximum distance a subject can walk on a flat surface within 6 minutes is measured. The reported value is the total walking distance (meters). A greater distance indicates better walking endurance.
Time frame: 1-month post-intervention (T1), 3-month post-intervention (T2).
Visual Analogue Scale (VAS)
Assessed using the Visual Analogue Scale (VAS) to evaluate the subject's average pain intensity over the past 24 hours. Subjects mark their pain level on a 10-cm line anchored with "no pain" (0) and "worst pain imaginable" (10). The reported value is the distance from the start point to the mark (centimeters). A higher score indicates more severe pain.
Time frame: 1-month post-intervention (T1), 3-month post-intervention (T2).
Range of Motion Measurement
The active range of flexion of the affected hip joint is measured using a universal goniometer. The reported value is the angle of flexion (degrees). A greater angle indicates better joint mobility function.
Time frame: 1-month post-intervention (T1), 3-month post-intervention (T2).
Psychological Assessment
Assessed using the anxiety subscale (HADS-A) of the Hospital Anxiety and Depression Scale (HADS). This subscale comprises 7 items, each scored from 0 to 3 points. The total score ranges from 0 to 21 points. A higher score indicates more severe anxiety symptoms. The reported value is the total subscale score for anxiety (points).
Time frame: Baseline (T0), 1-month post-intervention (T1), 3-month post-intervention (T2).
Proteomics Analysis
Proteomic analysis is performed on fasting venous blood samples to compare protein expression profiles between different time points (T1/T2 vs. T0) and between groups (intervention vs. control). The reported value is the number of statistically significant differentially expressed proteins identified under set significance thresholds (e.g., p\<0.05 and fold change \>1.5).
Time frame: Baseline (T0), 1-month post-intervention (T1), 3-month post-intervention (T2).
