Objectives

Narrative objectives1

The purpose of this study is to examine the perioperative recovery process by combining patients perioperative experiences following surgery for lumbar spinal stenosis with changes in their physical function before and after surgery.

Basic objectives2

Others

Basic objectives -Others

Although it is generally accepted that physical therapy administered over a 3-month period following surgery is effective in reducing pain and improving activities of daily living (ADL) in patients with lumbar spinal stenosis, there are few reports on studies combining quantitative and qualitative data. Therefore, this study aims to clarify changes in physical function and quality of life (QOL) before and after surgery in patients with lumbar spinal stenosis by examining their perioperative experiences.

Other related information

The questionnaire survey will include the Numerical Rating Scale to measure pain intensity; the Zurich Claudication Questionnaire to assess quality of life related to neurological symptoms of lumbar spinal stenosis; the Roland-Morris Disability Questionnaire to assess QOL related to low back pain; and the EuroQol-5D5L to measure health-related QOL. Physical function assessments will include the 10-meter walk test to measure walking speed and the Short Physical Performance Battery to comprehensively assess balance, gait, and muscle strength.
The interview survey will be conducted by the principal investigator using a semi-structured interview following the quantitative survey at 2 weeks post-surgery to investigate participants experiences during the postoperative recovery process.
