Activity 4 Gait & Lower-Extremity Integration Analysis

Due Friday, February 27 @ 12:00 PM (Noon)

Worth: 20 pts

Instructions:

Students will analyze a basic gait cycle OR a simple lower-body movement (walking, jogging, stepping up, lateral step, basic jump).

For their chosen movement, they must identify:

1. Hip, knee, and ankle joint actions throughout the movement
2. The plane & axis for each action
3. The joint type involved
4. Whether the movement is open- or closed-chain
5. One common movement error
6. Which structures (muscle, joint, neural) might cause the error
7. A brief prescription for improvement (Ch. 1 concept)

Example for Students:

Movement: Walking

• Heel strike dorsiflexion + knee extension + hip flexion
• Midstance neutral ankle + knee flexion + hip extension
• Toe-off plantarflexion + knee flexion + hip extension
• Closed-chain
• Possible error: Overpronation
• Correction: Strengthen tibialis posterior, glute med; address footwear

This assignment ties together Modules 5, 6, and 7 beautifully.
