Abstract：Objective To detect the reliability,validity and reaction degree of the modified lumbocrural pain patient-reported outcomes (PRO) scale,and explore whether it could be objectively used as a tool to evaluate the surgical efficacy of lumbar spinal stenosis using intervertebral foramen endoscope.Methods Sixty patients with lumbar spinal stenosis under intervertebral foramen endoscope were collected.Modified lumboerural pain PRO scale was used to assess the surgical efficacy,reliability,validity and reaction degree.Results The acceptance and completion rates of modified PRO scale were 100％,and there was no significant difference between first and second test (P＞0.05).The linear correlation analysis showed Cronbach'α coefficient value was positive correlate with Guttman split half reliability coefficient (r＞0.9).Positive correlation existed between Guttman split half reliability coefficient and Cronbackα coefficient value of the total scores and scores in all directions (r＞0.8).Internal reliability and validity in the scale and its various aspects were better.The total score and every average were lower in second test than first test (P＜0.05).The reaction degree evaluation of the modified PRO scale was higher.Conclusion Modified PRO scale has a good reliability,validity,and reaction degree,meanwhile it is very suitable for evaluating surgical efficacy of lumbar spinal stenosis under transformational endoscope.
