Cinemática da articulação do joelho e atividade eletromiográfica de músculos do membro inferior durante a marcha em ambiente aquático e terrestre / Kinematics of the knee joint and activity electromyographic of lower limb muscles during underwater gait

RESUMO

The objective of this study was to present the electromyographic pattern of lower limb muscles during underwater gait. It was also aimed at presenting the knee angular position and angular velocity and compare them during gait on land. Ten subjects with no history of injury in the locomotor apparatus were selected. Superficial, difterential, active, pre-amplifled electrodes were used to colect electromyographic signals from muscles vastus lateralis biceps femoris. tibialis anterior and gastrocnemius lateralis. The pared t-test was used. It was concluded that there is a consistent elec tromyographic activation pattern during the underwater gait for the studied muscles, and these muscles maintain the same synergism during walking on land surface. It was also concluded that the knee joint kinematics temporal pattern differs according to the environment
