The aim of this study is to evaluate whether integrating a technology-based rehabilitation approach with conventional therapies in the rehabilitation of patients with proximal femoral fracture may be advantageous compared with conventional therapy alone. Specifically, the objective is to assess whether the addition of technology-assisted rehabilitation can improve cognitive function, in addition to motor function and overall abilities, compared with conventional rehabilitation alone. Furthermore, the study intends to explore the feasibility of implementing technology-assisted rehabilitation as a stable and routine component of everyday clinical practice, also considering the perspective of healthcare professionals.
This is a national, multicenter, non-profit, post-market interventional longitudinal clinical study designed to evaluate the effectiveness of integrating technology-assisted rehabilitation with conventional rehabilitation in elderly patients undergoing inpatient rehabilitation after surgically treated proximal femoral fracture. Eligible participants aged 65 to 89 years who have undergone surgical treatment for proximal femoral fracture (total hip arthroplasty, partial hip arthroplasty, or intramedullary nailing) and who are clinically stable will be enrolled during their inpatient rehabilitation stay. After enrollment, patients will be randomly assigned to one of two treatment arms: (1) conventional rehabilitation alone (control group) or (2) integrated rehabilitation combining conventional therapy with sensor-based technology-assisted rehabilitation (experimental group). Randomization will be centralized and stratified by center and age group. The total rehabilitation program consists of 18 sessions delivered over approximately 3-4 weeks, with a frequency of 5-6 sessions per week. Patients in the experimental group will perform approximately one-third of daily rehabilitation sessions using sensor-based digital devices providing real-time visual and auditory feedback, and two-thirds with conventional rehabilitation. Technology-assisted training includes facilitated active joint mobilization, motor and cognitive stimulation tasks, and gait training. The control group will receive conventional rehabilitation only, including assisted joint mobilization, postural re-education, muscle strengthening exercises, and gait training with assistive devices. Clinical assessments will be performed at baseline (T0) and at the end of the rehabilitation program (T1). Motor performance will be assessed using the Timed Up and Go (TUG) test, which measures the time required for a participant to stand up from a chair, walk three meters, turn around, walk back, and sit down, as well as the Timed Up and Go Dual Task (TUG Dual Task), which evaluates mobility under simultaneous cognitive or motor task conditions. Additional functional outcomes include the Harris Hip Score, Barthel Index, pain assessed by Numeric Rating Scale, and health-related quality of life assessed by the SF-36. Cognitive status will be assessed using the Mini-Mental State Examination (MMSE). Blood samples will be collected at T0 and T1 to measure serum brain-derived neurotrophic factor (BDNF) levels and to analyze the rs6265 (Val66Met) polymorphism. The primary endpoints are the change in serum BDNF levels and the change in TUG and TUG Dual Task performance from baseline to the end of treatment. Secondary endpoints include changes in functional scores, pain, quality of life, and exploratory analysis of the BDNF genetic polymorphism. Healthcare professionals involved in the rehabilitation program will also complete the Work-Related Quality of Life (WRQoL) questionnaire to explore the perceived impact of technology-assisted rehabilitation on work-related quality of life. Statistical analysis will be performed to evaluate differences between the control and experimental groups and changes over time in outcome measures. A p-value \< 0.05 will be considered statistically significant.

The technology/robotic group will perform one-third (1/3) of the daily rehabilitation using technology-assisted devices and two-thirds (2/3) using conventional rehabilitation. In addition to the conventional rehabilitation described below, the treatment will include technology-assisted rehabilitation consisting of facilitated active joint mobilization exercises with visual and auditory feedback, aimed at stimulating motor and cognitive functions, as well as gait training.
The conventional rehabilitation programme includes assisted and facilitated joint mobilization exercises to improve range of motion; exercises for postural readaptation of the trunk to the upright position; isometric exercises; and gait training using a 4-wheeled walker or forearm crutches (Canadian crutches), aimed at improving walking ability and achieving an appropriate recovery of the gait pattern.

Changes in serum BDNF levels
Difference in serum brain-derived neurotrophic factor (BDNF) levels between baseline and the end of the rehabilitative treatment, assessed to evaluate biomolecular changes associated with neuroplasticity.
Time frame: Baseline and within 3 days after completion of the rehabilitative treatment
Change in Timed Up and Go test
Difference in functional mobility, balance, and gait performance assessed using the Timed Up and Go test between baseline and end of rehabilitative treatment.
Time frame: Baseline and within 3 days after completion of the rehabilitative treatment
Change in Timed Up and Go Dual Task test
Difference in cognitive-motor dual-task performance assessed using the Timed Up and Go Dual Task test between baseline and end of rehabilitative treatment.
Time frame: Baseline and within 3 days after completion of the rehabilitative treatment
Change in the Harris Hip Score (HHS)
Change in hip function, pain, and functional ability as assessed by the Harris Hip Score, a clinician-administered outcome measure ranging from 0 to 100 points, where higher scores indicate better hip function, assessed at baseline and at the end of the rehabilitative treatment.
Time frame: Baseline and within 3 days after completion of the rehabilitative treatment
Change in the modified Barthel Index
Change in independence in activities of daily living as assessed by item-level scores of the Barthel Index, a validated measure of functional independence ranging from 0 to 100 points, where higher scores indicate greater independence, assessed at baseline and at the end of the rehabilitative treatment (Italian version, 2015).
Time frame: Baseline and within 3 days after completion of the rehabilitative treatment
Change in pain intensity measured by the Numeric Rating Scale (NRS)
Change in pain intensity as assessed by the Numeric Rating Scale, a patient-reported outcome measure ranging from 0 to 10, where higher scores indicate greater pain intensity, assessed at baseline and at the end of the rehabilitative treatment.
Time frame: Baseline and within 3 days after completion of the rehabilitative treatment
Change in quality of life measured by the SF-36
Change in health-related quality of life as assessed by the 36-Item Short Form Health Survey (SF-36), a validated patient-reported outcome measure composed of multiple domains, each scored on a 0 to 100 scale, where higher scores indicate better health-related quality of life, assessed at baseline and at the end of the rehabilitative treatment.

Analysis of the rs6265 polymorphism (Val66Met mutation) of the BDNF gen
Genotyping of the BDNF rs6265 (Val66Met; G196A) single-nucleotide polymorphism to classify participants as Val/Val, Val/Met, or Met/Met and explore its association with serum BDNF levels and rehabilitative outcomes.
