Introduction: Gait in individuals with neurological sequelae following a cerebrovascular event is often altered due to joint restrictions that impair functional mobility. The swing phase represents a key moment for detecting such alterations.
Objective: To analyze the degree of joint impairment in the hip, knee, and ankle during the swing phases of gait in individuals with motor impairment secondary to a cerebrovascular event, using angular measurements obtained through digital analysis tools.
Methodology: A descriptive cross-sectional study was conducted with 30 participants. A two-dimensional angular analysis in the sagittal plane was applied, assessing the initial, mid, and terminal swing phases. Measurements were processed using Kinovea and compared to established functional reference ranges.
Results: The greatest impairment was found in the knee during the terminal phase, with a difference of 56.5° from the expected functional range. The hip and ankle showed progressive alterations, with maximum differences of 39.5° and 36.5°, respectively. An interdependent pattern between joints was observed, extending beyond isolated segmental impairment.
Discussion: The findings are consistent with previous studies that describe joint stiffness, compensatory mechanisms, and asymmetry in post-stroke patients. The methodology enabled detailed characterization by phase and segment, using low-cost tools with clinical applicability.
Conclusion: The segmented analysis facilitated the identification of clinically relevant joint deficits, providing objective values to guide rehabilitation. The detection of impairments of up to 56.5° highlights the utility of this approach for planning targeted therapeutic interventions based on the specific joint and gait phase involved.
