The goal of this clinical trial is to improve comprehensive rehabilitation programs for elderly patients with chronic cerebral ischemia by incorporating training methods with biofeedback for postural control training. The main objectives of the study are as follows: To evaluate the effectiveness of incorporating stabilometric training with biofeedback using the Huber system (LPG Systems, France) and treadmill-based biofeedback training using the C-Mill system (Physiomed Elektromedizin AG, Germany) into comprehensive rehabilitation programs, with respect to postural and cognitive functions in elderly patients with chronic cerebral ischemia. To conduct a comparative analysis of the effectiveness of training programs performed using the Huber (LPG Systems, France) and C-Mill (Physiomed Elektromedizin AG, Germany) biofeedback systems, based on outcomes related to gait pattern recovery, postural parameters, and cognitive performance. The investigators will compare training sessions using the Huber and C-Mill biofeedback systems with a control group (patients receiving conventional therapeutic exercise) in order to determine whether these devices are effective in improving postural control and reducing the risk of falls in patients with chronic cerebral ischemia. Participants are required to: Complete a course consisting of 8 procedures, performed once daily. Report any adverse events occurring during or after the procedures, should they arise.
This randomized controlled clinical study is designed to evaluate the effectiveness of biofeedback-based training methods incorporated into comprehensive rehabilitation programs for elderly patients with chronic cerebral ischemia. The study population consists of patients aged 65 years and older with a confirmed diagnosis of chronic cerebral ischemia (ICD-10: I67.8) of atherosclerotic, hypertensive, or mixed etiology, presenting with clinical stage I or II disease and neuroimaging-confirmed structural brain changes. Participants will be randomized into three parallel groups with stratification to ensure comparability by age and severity of cognitive impairment. Two intervention groups will receive standard inpatient rehabilitation combined with device-based training using biofeedback technologies. The first intervention group will undergo stabilometric training using the Huber system (LPG Systems, France), aimed at improving static and reactive components of postural control. The second intervention group will receive treadmill-based gait and balance training using the C-Mill system with visual biofeedback (Physiomed Elektromedizin AG, Germany), targeting dynamic balance, gait pattern restoration, and fall risk reduction. The control group will receive standard rehabilitation without device-based biofeedback training. All participants will complete a comprehensive inpatient rehabilitation program lasting 10 days. Each program includes therapeutic exercise focused on general strengthening, balance, and coordination, as well as classical relaxing massage of the cervical-collar region and magnetotherapy when clinically indicated. Participants in the intervention groups will additionally complete 8 device-based training sessions. To ensure comparability across groups, the duration of active training time per session will be standardized and will range from 23 to 24 minutes. Clinical and instrumental assessments will be conducted before and after the rehabilitation course to evaluate changes in postural stability, gait, mobility, cognitive function, fall risk, and quality of life. Fall risk will be assessed using the Morse Fall Scale, mobility using the Timed Up and Go Test, and cognitive function using the Montreal Cognitive Assessment. Instrumental evaluation of gait and balance will be performed using the C-Mill diagnostic C-Gait program, while postural and pedometric parameters will be assessed using the diagnostic module of the Huber system. Quality of life and psychological well-being will be evaluated using the EQ-5D-3L questionnaire. The study hypothesizes that rehabilitation programs incorporating biofeedback-based device training will lead to more pronounced improvements in postural control, gait parameters, cognitive function, and fall risk reduction compared to conventional therapeutic exercise alone. It is expected that treadmill-based training using the C-Mill system will demonstrate a greater effect on dynamic balance and gait-related outcomes, whereas stabilometric training using the Huber system will primarily enhance static and reactive balance components. Improvements in quality of life are anticipated to be more pronounced in the biofeedback intervention groups.

Procedures on the Huber stabilization trainer (LPG-Systems, France) include a 5-minute warm-up, followed by an individual selection of 3 tasks from the "Balance and Posture" program and 2 tasks from the "Resistance" program from levels 1 to 5.
The procedures on the C-mill biofeedback video reconstruction track (Physiomed Elektromedizin AG, Germany) include a warm-up (3 minutes of normal walking), followed by blocks of tasks of 2-4 minutes each: "Slalom", "Tandem", "Obstacles", "Random Marks", "Speed Change", and ending with a cool-down (3 minutes of normal walking).
The therapeutic exercise program consists of complex coordination exercises in various starting positions, including with objects. Each session will include a 5-minute warm-up, including breathing exercises and active joint exercises, followed by a 15-minute main block of exercises, and concludes with a 3-4-minute cool-down with stretching exercises for the back and lower extremities.

The risk of falls was reduced more in groups using biofeedback equipment
Fall risk assessment using the Morse fall scale before and after the rehabilitation course (min 0, max 125, higher values on the scale indicate a worse outcome)
Time frame: 10 days
The risk of falls was reduced more in groups using biofeedback equipment
Fall risk assessment using the Get-Up-and-Go test before and after the rehabilitation course (Taking more than 14 seconds to complete the test indicates a high risk of falls)
Time frame: 10 days
The risk of falls was reduced more in groups using biofeedback equipment
Fall risk assessment using the gait speed before and after the rehabilitation course (a walking speed of more than 1 km/h indicates a high risk of falls)
Time frame: 10 days
Static balance will improve more in the group training on the "Huber", and dynamic balance in the group training on the treadmill "Cmill"
Evaluation based on the following stabilometric indicators: length and area of the statokinesiogram, average speed of oscillations of the body's center of pressure, indicators of the static and dynamic balance tests TUG, Romberg test with open and closed eyes, indicators of the dynamic walking stereotype (walking speed, step length, step variability)
Time frame: 10 days
Improving cognitive functions
Montreal Cognitive Assessment (MoCA) (min 0 max 30 points, a higher score means a better result)
Time frame: 10 days
Improving the quality of life
EQ-5D-3L questionnaire (EuroQol five-dimension three-level questionnaire).The first part of the scale has a system of indices that form a code that does not calculate to a single score. The second part of the scale EQ VAS (scale from 0-100), has a range from 0 to 100, where 100 is the best state.
Time frame: 10 days
