- Normal Walking is 2.5 mph (1.12 m/s) – 4.0 mph (1.79 m/s)
• Necessary for terminal hip extension
- Combination of loading and hip extension sends signals to the spinal cord which activates the contralateral hip flexors and sends signals that the next
action for the ipsilateral hip flexors is to engage.
• Minimize sensory blocks during LT (ie. heavy shoes)
• Challenge with variation (alternating TM speed, stepping over objects, dynamic or cognitive tasks)
99
How do we optimize kinematics for Locomotor Training (LT)?

* Avoid reinforcing compensatory strategies that lead to abnormal kinematics during motor tasks.
100

when not in the clinic.
