Abstract:

BACKGROUND: Analgesia following artificial joint repacement commonly utilizes patient-controlled method, which has many side effects. Continuous peripheral nerve block analgesia is safe and effective, but it may affect activity of patients following artificial joint repacement due to local numbness. Currently, studies are few regarding gait analysis used to evaluate effect of different analgesia methods on early activities of patients following artificial joint repacement.
OBJECTIVE: To compare the effect of continuous nerve block (including femoral nerve block and fascia iliaca compartment block) and patient-controlled intravenous analgesia (PCIA) for postoperative pain control on gait after total hip and knee replacement.
METHODS: A total of 17 volunteer subjects were selected including 7 injected with PCIA after operation, 6 with femoral nerve block and 4 with fascia iliaca compartment block. Subjects were asked to walk at their own paces with barefoot on a 10 m walkway with a 0.5m footscan® plate (footscan® from RSscan International, Olen, Belgium). Barefoot walking gaits were compared before and after replacement. 
RESULTS AND CONCLUSION: There were no significant differences between continuous nerve block and PCIA for postoperative pain control in the parameters (P > 0.05). The parameter changes in patients undergoing fascia iliaca compartment block were less than PCIA patients (P < 0.05). Of 17 patients, effects of fascia iliaca compartment block were superior over PCIA, and femoral nerve block was similar to PCIA following artificial joint replacement.
