Gait Analysis after Amputation eMedicine Orthopaedics
Amputation is one of the most emotionally upsetting and traumatic events that a patient can undergo. However, with a team approach by the medical staff, the negative effects can be minimized and the positive benefits emphasized. Equipping the patient with a prosthesis not only greatly improves the patient's functional status but also helps his or her psyche.

Gait Analysis eMedicine PMR
Walking is the most convenient way to travel short distances. Free joint mobility and appropriate muscle force increases walking efficiency. As the body moves forward, one limb typically provides support while the other limb is advanced in preparation for its role as the support limb. The gait cycle (GC) in its simplest form is comprised of stance and swing phases. The stance phase further is subdivided into 3 segments, including (1) initial double stance, (2) single limb stance, and (3) terminal double limb stance.

Normal Gait: (two phases):
- stance phase:
- begins w/ heel-strike and ends w/ toe-off &, in terms of duration, constitutes 63% of the cycle of gait (during walking):
- hence, during ambulation there are two periods of double support (beginning and end of stance phase);
- w/ running, toe off occurs earlier in the gait cycle, and there is no point when both feet are on the ground, and instead there are two time points when both feet are off the ground simultaneously (just before and after stance phase);
- the faster the run, the less time is spent in stance phase;
- swing phase:
- begins w/ toe-off & ends w/ heel-strike, comprising 28% of cycle;
- duration of each phase is same for both limbs, circumstance, among others, that confers upon normal gait appearance of symmetry & rhythm;
- abnormality of gait is usually a consequence of pain, weakness, or a difference in the lengths of the limbs;
- normal gait tends to minimize displacement of center of gravity thru: - pelvic rotation - pelvic tilt - knee flexion after heel strike - foot and ankle motion - knee motion - lateral displacement of pelvis
