Clean FRCS notes with inline figures
Gait analysis
•Systematic description, assessment and measurement of the quantities that characterize human locomotion
•From top to bottom
•Pelvis, hip, knee, ankle
•Left hand side of graph = stance phase
•Right hand side of graph = swing phase
•Increase knee flexion in stance phase
•Increase ankle DF in stance phase
•→ Crouch gait
Components:
•Kinematic
•Kinetic
•EMG
•Energy consumption
•Biomechanics: study of biomaterial response to load (static vs dynamic)
Kinematic: study on motion over time = ROM
Kinetic: study on force associated motion = force
Set up:
•1. 2D video analysis
•2. 3D computer analysis using specialized markers on specific bony landmarks
•3. Force plates to measure GFR
•4. EMG to look at muscle firing patterns
