Резюме: Objective: Gait disorders in post-stroke patients are caused by factors such as the severity of motor paralysis, sensory impairment, spasticity, instability, and gait strategy. Severe motor paralysis and spasticity lead to abnormal muscle activity patterns that affect the kinematics of the lower limbs during walking. Sensory impairment and loss of balance lead to impaired motor coordination of the lower limbs, stride length and balance. This report presents a system for electromyographic and kinematic gait assessment in patients one year after stroke. Materials and methods: The 10-Meter Walk Test (10MWT) and a portable electromyographic system for the objective measurement of kinematics and muscle activity (FREE EMG and G-Walk sensor, BTS Co., Italy) were used. Results: Increased stride length on the affected side, slightly longer stance phases, and decreased walking speed and cadence were revealed. Stride time, the duration of the single stance phase in both lower limbs and double stance time were increased, with the deficit being more pronounced on the left side. Increased obliquity in the gait cycle of the affected side often indicates pelvic 'hiking' — a compensation for insufficient dorsiflexion and/or limited knee flexion during the swing phase. Discussion: According to the authors, hemiplegic gait after stroke comprises deviations and compensatory movements dictated by residual functions. Therefore, each patient should undergo examination to identify and document their unique gait pattern. Conclusion: Early diagnosis, regular functional assessments, and targeted rehabilitation are essential for improving gait and independent performance of activities of daily living in patients.
