Lazansky developed a method for grading mobility in a patient with a hip disorder. This can be used to evaluate a patient before and after hip surgery. The author is from Albert Einstein College of Medicine in New York City.
NOTE: Lazansky also included grading of pain and function when assessing the hip (see previous section). These can be combined into an overall score (see next section)..
Parameter:
(1) Gade's mobility index (for left and right side)
(2) abduction against gravity (for left and right side)
(3) straight leg raising (for left and right side)
(4) shortening
(5) separation of feet (intermalleolar distance)
(6) contracture

total sum for mobility =
= (2*(points for Gade's index in left hip)) + (2*(points for Gade's index in right hip) + (points for abduction in left hip) + (points for abduction in right hip) + (points for straight leg raising in left hip) + (points for straight leg raising in right hip) + (points for shortening) + (points for separation of feet) + (points for contracture on left side)+ (points for contracture on right side)
total score for mobility =
= (total sum of mobility points) / 12
Interpretation:
• minimum total score for mobility: 12
• maximum total sum for mobility: 71
• minimum total score for mobility: 1
• maximum total score for mobility: 5.91
