Abstract: Combat trauma and prolonged immobilization naturally lead to the development of resistant combined contractures of the lower limb joints. This creates an urgent need for innovative approaches, specifically the use of modern robotic systems with biofeedback for targeted tissue remodeling. Aim – to improve the effectiveness of rehabilitation in patients with combined contractures of the lower limb joints through the integration of the “Omego Plus” system into the standard protocol. The randomized study included 69 patients (aged 20-49 years) diagnosed with combined contractures of the lower limb joints. The main group (n=34) received standard physical therapy and training using the “Omego Plus” system (60 min, 5 times/week, for 6 weeks). The control group (n=35) received only standard physical therapy (according to NICE-2022 guidelines). Assessments using goniometry, manual muscle testing (MMT), the Visual Analogue Scale (VAS) for pain, and the 10-Meter Walk Test (10MWT) were conducted at baseline, after 6 weeks, and 3 months. A statistically significant increase in the range of motion was recorded in the main group (flexion in the knee joint up to 115°, dorsiflexion in the ankle joint up to 15°, showing a significant advantage over the control group). Significantly higher strength indices of the pelvic stabilizers (an average of 1-1.5 points higher compared to the control group, p<0.001) were observed, confirming the effective recruitment of motor units. The 10MWT revealed a cumulative effect of the “Omego Plus” system, with the formation of a statistically significant intergroup advantage at the final stage of observation (walking speed increased by 0.44 m/s in the main group vs. 0.36 m/s in the control group, p<0.05). A reduction in pain syndrome intensity was recorded in both groups, but the result was better in the main group (VAS score decreased by an average of 3.9 points in the main group vs. 3.1 points in the control group, p<0.05). The implementation of the “Omego Plus” system in the subacute rehabilitation period is pathogenetically justified. Despite the depth of structural changes, the system provides clinically significant restoration of mobility, an increase in muscle strength, and a sustained reduction in pain in the long-term period. The results demonstrate the superior effectiveness of the applied method over the standard one for structural tissue remodeling and overcoming therapeutic resistance.
