#### Transcripts - Kinetic Concepts for Analyzing Human Motion

• 1. Kinetic Concepts for Analyzing Human Motion Presentation Created by Dr. Hazrat Bilal Malakandi. PT DPT (IPM&R, KMU)
• 2. Objectives • Qualitative analysis • Identify common units of measurement for mass, force, weight, pressure, volume, density, specific weight, torque, and impulse • Identify and describe the different types of mechanical loads that act on the human body • Identify and describe the available instrumentation for measuring kinetic quantities • Solve quantitative problem involving vector quantities using both graphic and trigonometric procedures
• 3. Basic Concepts Related to Kinetics • Inertia • Mass • Force • Center of Gravity • Weight • Pressure • Volume • Density • Specific weight • Torque • Impulse
• 4. Common Units for Kinetic Quantities Quantity Symbol Metric Unit English Unit Mass m kg slug Force F N lb Pressure P Pa psi Volume (solids) V m3 ft3 (liquids) liter gallon Density  kg/m3 lb/ft3 Specific weight  N/m3 lb/ft3 Torque T N-m ft-lb Impulse N • s lb • s
• 5. Mechanical Loads on the Human Body • Compression • Tension • Shear • Stress • Torsion • Bending • Combined loading
• 6. Repetitive vs. Acute Loads • Repetitive loading • Acute loading • Macrotrauma • Microtrauma
• 7. Tools for Measuring Kinetic Quantities • Electromyography (EMG) – To study neuromuscular function • Dynamography – Primarily employed in gait research – Starts, takeoffs, landings, baseball & golf swings, and balance
• 8. Vectors & Scalar Quantities • Kinetic vector quantities – force weight, pressure, specific weight & torque • Kinematic vector quantities – Displacement, velocity & acceleration • Scalar quantities – Mass, volume, length & speed
