The study aim was to compare
kinematics and muscles activity of normal gait and swimming exercises
and those of subjects with Down’s syndrome and Autism. An
original video-computer methodology was used to estimate kinematics and
modeling the activity of 9 muscles: m. gluteus maximus, m.
semimembranosus, m. semitendinosus, m. biceps femoris, m. rectus
femoris, m. vastus lateralis, m. gastrocnemius и m. soleus. Normalized
stride registered data were averaged for complete cycle. Phase
structure, line velocity, speed of movement and angle kinematics were
estimated. A comparative analysis has been performed investigating test
persons based on Ferrigno and Pedotti model. The quantitative results
supported the analysis of the disturbances in the passive and active
parts of the locomotors system. The types of functional disorder
compensations were found out.
KEY WORDS: cyclical
kinematical analysis, video-computer analysis, locomotors system model.
