简要总结
The goal of this observational case-control study is to learn whether low back pain is associated with changes in gait and related clinical characteristics in adults over 18 years old. The main questions it aims to answer are:
- Are gait biomechanics different in people with low back pain compared with people without low back pain?
- Are pain intensity, psychosocial risk, and physical activity levels different between both groups? Participants will complete questionnaires about low back pain, physical activity, and health status, and will perform a walking test in a motion analysis laboratory where gait parameters are recorded.
详细描述
This study is an observational case-control investigation designed to explore the relationship between low back pain and gait biomechanics in adults. Low back pain is a common health problem that may affect movement patterns, physical function, and daily activities. Understanding how gait is modified in people with low back pain may help to improve assessment and rehabilitation strategies.
Participants will be divided into two groups: adults with low back pain and adults without low back pain. Sociodemographic and clinical characteristics will be collected to describe the sample and to allow comparisons between groups. The study will focus on the analysis of spatiotemporal, kinematic, and dynamic gait parameters obtained in a motion analysis laboratory.
Gait assessment will be performed using a three-dimensional motion capture system. In addition to gait analysis, participants will provide information about their health status, pain characteristics, physical activity, and psychosocial factors through self-report questionnaires. These variables will be used to describe the clinical profile of the participants and to examine potential associations with gait outcomes.
Comparisons between the low back pain group and the control group will be conducted to identify differences in gait biomechanics and clinical characteristics.

研究组 & 干预措施
Low Back Pain Group
Adults over 18 years with current or recent low back pain without leg pain, who undergo clinical assessment and gait analysis in a motion laboratory.
Control Group
Adults over 18 years without low back pain who undergo the same clinical assessment and gait analysis as the low back pain group.
