Peak velocity of elbow joint during touching contra lateral shoulder activity for normal subject

A better understanding of upper limb movements requires analysis of motion. Measurements of movement analysis through biomechanical studies are necessary to describe upper limb activities. Therefore this study intend to investigate peak velocity of elbow joint for different age groups during the “touching contra lateral shoulder” activity. Twenty healthy subjects age range 20 – 59 years old (n = 60) performed a complete cycle of hand lifting, resting and returning the hand to its initial position. This activity was analyzed using Vicon motion-analysis system, which consists of three infra-red and high speed cameras. Phase definitions were defined and descriptive kinematic variables were obtained from this activity. Movement times is found to increase in 50’s age group. The difference of movement times is < 0.3s. Peak velocity for subject age 50s’ also higher between all subjects. The difference of peak velocity is < 0.03m/s for all different phases. It was found that there were a significant difference in total movement time and no significance different between each age group for peak velocity parameter.
