SIGAM Mobility Grades for Lower Limb Amputation | Medical Algorithm

The Special Interest Group in Amputee Medicine (SIGAM) use a scale for grading mobility in a patient with a lower limb amputation.

Patient selection: lower limb amputee

Clinical Finding	Grade
does not wear a limb prosthesis	A
only wears a limb prosthesis for cosmetic purposes	A
only wears prosthesis for transfers or to assist nursing or only walks indoors or needs assistance from someone else	B
only walks on level ground <= 50 meters with or without use of a walking aid	C
walks on level ground outdoors in good weather > 50 meters with or without use of a walking aid	D
walks > 50 meters independent of walking aid (may use walking aid to improve confidence or in inclement weather or for difficult terrain)	E
normal or near normal gait	F

where:

• The person can be subgraded based on the 2alking aids: (a) frame, (b) 2 crutches or sticks, (c) 1 crutch or stick, (d) none.

• One modification would be to divide Grade E based on distance walked, assuming that Grade F implies the ability to walk a long distance.
