Materials: (1) 20 cm high step.

Methods:

  • The patient is asked to stand in single limb support with the hands on the waist, the knee straight and the foot positioned close to the edge the step
  • The contralateral leg is positioned over the floor adjacent to the step and is maintained with the knee in extension
  • The patient then bends the tested knee until the contralateral leg gently contacts the floor and then re-extends the knee to the starting position
  • This maneuver is repeated for 5 repetitions

Interpretation:

Criteria Interpretation Score
Arm Strategy Removal of hand from waist +1
Trunk Alignment Leaning in any direction +1
Pelvic Plane Loss of horizontal plane +1
Knee Position Tibial Tuberosity medial to second toe +1
Tibial Tuberosity medial to medial border of foot +2
Steady Stance Patient stepped onto non-tested limb, or foot wavered from side to side +1
  • Total score of 0 or 1 was classified as good quality of movement
  • Total score of 2 or 3 was classified as medium quality
  • Total score of 4 or above was classified as poor quality of movement

Reliability:
