    Opis:
    Background: Osteoarthritis, which causes pain, deformities and instability of the rearfoot, is the most common indication for ankle arthrodesis. The aim of this study was to present the influence of the ankle arthrodesis on the performance of this joint in the three planes during walking at natural velocity.Materials and methods: Fourteen patients, age from 34 to 66 years (mean: 54 years), with ankle arthrodesis participated in the testing procedures. Angular changes of the ankle in the three planes of movement during particular gait phases and spatiotemporal gait parameters were evaluated by a three–dimensional motion analysis system, Vicon®. The study was performed at the Biokinetics Laboratory of the Academy of Physical Education in Kraków. The results of locomotion analysis were compared to a control group, consisting of thirty healthy persons aged 40–65 years.Results: In the saggital plane feet joints worked symmetrically during all gait phases, but there were angular changes of plantar and dorsal flexion, which were different from biomechanical norm. In frontal plane, feet were in abduction during almost all gait phases. In the transversal plane, feet were in internal rotation. Significant differences in spatiotemporal gait factors were observed between the two groups.Conclusions: Ankle arthrodesis leads to significant changes in motion pattern of the ankle joints.

    Opis:
    Background: Ankle arthrodesis is probably still the safest method of treating painful, lesioned ankle in patients with rheumatoid arthritis or osteoarthritis with significant symptoms that do not respond to conservative treatment. The aim of this study was to present the effects of the ankle arthrodesis on correct functioning of the knee and hip joints during walking at natural velocity.Materials and methods: The study was conducted in the Biokinetics Laboratory of the Academy of Physical Education in Kraków. Fourteen patients with ankle arthrodesis, aged from 34 to 66 years (mean: 54 years), were enrolled into the study and participated in the testing sessions. Angular changes of the knees and hips in three planes of movement during particular gait phases were evaluated by a three–dimensional motion analysis system: Vicon®. The results of locomotion analysis were compared to a control group that consisted of thirty healthy persons aged 40–60 years.Results: Significant differences in the movement of the knees and hips in the three planes of motion were observed between the two groups. In the frontal plane, knees moved symmetrically, but during all the gait phases, knees were in a significant valgus deformity. In the transversal plane, knees were in a significant external rotation during all gait phases. In the saggital plane, hips moved with limited extension. There was also a significant external rotation, outside the biomechanical normal range, of both hips in the transversal plane.Conclusions: The most significant deviations from the biomechanical normal range were found in the frontal and transversal planes for knees and in the saggital and transversal planes for hips.

    Opis:
    Purpose: A novel portable system has been used to evaluate spatial knee movement, but its accuracy and repeatability is not known. The aim of this study was to investigate the accuracy and repeatability of the measurement. Methods: Ten healthy participants were included, and the knee motion trajectory during walking were assessed. Six evaluations were conducted (three days by two raters) for each participant. The motion parameters at the key points and the range of motion were statistically analyzed. Intraclass correlation coefficients (ICC), standard error of the measurement (SEM), and the Bland–Altman method were used. Results: For intra-rater repeatability, 1) the ICC values range from 0.75 to 0.9 for rotations; and 0.64 to 0.96 for translations. Among the ICC values, 100% of rotations and 90% of translations were not less than 0.70; 2) among the SEM values, 100% of rotations were not more than 5°, while 73.3% of translations were less than 3 mm. For inter-rater repeatability, 1) the ICC values range from 0.68 to 0.99 for rotations; and 0.57 to 0.93 for translations. Among the ICC values, 95.6% of rotations and 82.2% of translations were not less than 0.70; 2) among the SEM values, 100% of rotations were not more than 5°, and 48.9% of translations were less than 3 mm. The Bland–Altman plots showed good agreement for intra- and inter-repeatability. Conclusions: The results indicated that the accuracy and repeatability of the measurement were acceptable, except for the inter-rater repeatability for translation. This may help researchers and physicians better interpret the measurement data.
