S. Khodadadeh et Sm. Eisenstein, GAIT ANALYSIS OF PATIENTS WITH LOW-BACK-PAIN BEFORE AND AFTER SURGERY, Spine (Philadelphia, Pa. 1976), 18(11), 1993, pp. 1451-1455
Gait analysis could be a good objective and quantifiable assessment of
function in patients with chronic low back pain. A study of the gait
parameters of 20 normal subjects and 30 patients with low back pain, b
efore and 2 years after surgery (mainly spinal arthrodesis) was undert
aken. For the majority (67%) of patients, postoperative gait analysis
confirmed their perception of pain and function. In a minority (33%) o
f patients, there was an improvement in gait parameters, despite the p
erception of continuing severe pain and poor physical functioning. It
may be possible to reduce the number of patients experiencing symptoma
tic failure with surgery if this discrepancy between gait and disabili
ty due to pain can be discovered preoperatively. Then the advice again
st surgery could be given when indicated.
