Abstract: This study aimed to assess the factors that influence The Oswestry Disability Index (ODI) clinical outcomes in patients with Lumbal Spinal Stenosis (LSS) after Percutaneous Stenoscopic Lumbar Decompression (PSLD). A total of 92 patients were analyzed for factors that affecting ODI clinical outcome. These factors were age, sex, body mass index, cigarette consumption, alcohol consumption, sports history, pain onset, radicular pain, VAS pain score, paresis and paresthesia symptoms, duration and conservative management, length of operation, duration of treatment, recurrence of pain, and duration of postoperative healing. Data were collected by direct examination, questionnaires, in-depth interviews, and patient medical records. A Pearson correlation or Spearman Rank test and independent T-test or Mann Whitney was conducted to determine the significant relationship between these factors and ODI clinical outcomes. Multiple linear regression was performed to find out which factor most influences ODI clinical outcome. Some factors influence ODI outcome in the sample as resulted by statistical analysis. From the statistic analysis, only three factors that influence the ODI postoperative there was age (p=0.003), VAS preoperative (p=0.001), and ODI preoperative (p=0.001). There was no statistical significance found in the other factors with p>0.005. Factors influencing clinical outcomes by ODI in patients with lumbar spinal stenosis after PSLD was the age of the patient, preoperative ODI, and preoperative VAS.
