  1. Gait Evaluation Athletic Injury Assessment Chapter 9, p. 303

  2. Gait Analysis • “Walking is a series of narrowly averted catastrophes”—p.303 • Gait=walking or running pattern • Analysis dictated by scope and length of injury • Ankle injury scenario • Abnormal gait often learned during times of injury • Observe: • Limb position • ROM • Force production • Timing/sequence

  3. Terms—p.303-304 • Antalgic gait • Stride length • Cadence • Center of Gravity

  4. Gait Analysis—p.304 • Video helpful • Ensure NML walking pace • Position yourself properly • Multiple views(A/P/Lat) • Focus on individual body parts first, then on entire body, then parts again • With/without shoes • Reassess often

  5. Normal Gait—p. 307 • Normal adult cadence~107 spm • Women cadence>men cadence • Stride length~75 cm • Vertical movement~5cm • Slight lateral motion • Rotation increases with gait speed • Gait affected by: • Intrinsic factors: • Joint ROM • Muscle strength • Body type • gender • Extrinsic factors: • Surface incline • Surface type • footwear

  6. Gait Phases—p.307 • Stance phase • Foot in contact with ground • Closed kinetic chain • High energy phase/propulsion • Swing phase • Foot moves through air • Open kinetic chain • Low energy phase

  7. Stance Phase—p. 308, 310 • Box 9-1, p. 310 • Initial contact • Loading response • Midstance • Terminal stance • Preswing

  8. Swing Phase—p. 308-309, 312 • Box 9-2, p. 312 • Initial Swing • Midswing • Terminal Swing

  9. Walking vs. Running—p. 314 • At no time are both feet in contact with the ground • Flight phase—neither foot in contact with ground • Arms move in opposition to LE’s • Decreased vertical movement • Fig. 9-5, p. 314
