Objective: To analyze the relationship of clinical factors and gait parameters of patients with failed back surgery syndrome.
Method: We investigated 25 male patients with back and /or lower limb pain who underwent lumbar spine operation. The following data were evaluated: clinical symptoms, physical examination, duration from operation to the gait analysis, number and level of operation, Visual Analogue Scales (VAS), modified Dallas pain questionnaire, psychological evaluations (Beck Depression Inventory, BDI) and gait parameters through 3 dimensional gait analysis.
Results: Walking velocity was inversely correlated with scores of modified Dallas pain questionnaire and BDI. Stride length was inversely correlated with scores of return to work, neurogenic claudication, VAS, modified Dallas pain questionnaire and BDI. Range of pelvic obliquity was inversely correlated with scores of modified Dallas pain questionnaire and BDI. There was no significant differences between findings of physical exam and gait parameters.
Conclusion: Results of the gait analysis of patients with failed back surgery syndrome showed significant relationship with clinical factors reflecting psychosocial background of patients.
