Q

Why do we analyze gait?

A
  • Identify deviations in gait in order to address with intervention.
  • Determine functional ambulation capability across variety of environments.
  • Assess balance, safety, endurance, energy expenditure as it relates to walking.
  • Determine need for assistive devices/orthotics.
  • Evaluate the effectiveness of your interventions; describe how your interventions impacted gait.

Q

What are the characteristic features of an Antalgic Gait?

A
  • Decreased stance phase duration on affected limb.
  • Lack of weight shift laterally over stance limb to keep weight off the involved limb.
  • Decrease in stance phase in affected side will result in decrease in swing phase of uninvolved limb and thus shortened step length on uninvolved side.
