Document Summary
Gait: while gate seems like a simple task, it requires relatively complex mechanical controls, use gait as a model of basic human activities, discussing a number of biomechanical variable that we can look at. Electromyography: diagnostic tool for measuring and evaluating muscle contraction and abnormalities, can be used to control prosthetics/robots. Kinematic analysis: marker kinematics, linear displacement, velocity and acceleration, segment kinematics, linear displacement, velocity and acceleration of the centres of gravity of each segment, angular displacement, velocity, and acceleration of each segment. Joint kinematics: linear and angular kinematics of various joints. Kinematic instrumentation: basic- ruler, tape measure etc, advanced- 3d motion capture etc. Digitizing: computerizing digitizing frame by frame, real-time digitizing vicon, qualisys, step 1: choose a market set. Market sets and models: anatomical and tracking markers, step 2: create a model based on calibration, step 3: apply the model to your motion trials. Joint forces and moments: work, energy and power.
