Low back pain (LBP) can lead to motor control disturbance which can be one of the causes of reoccurrence of the complaint. It is important to improve our knowledge of movement related disturbances during assessment in LBP and to classify patients according to the severity. The aim of this study is to present differences in kinematic variables using a RGB-D camera in order to classify LBP patients with different severity. A cross-sectional study was carried out. Subjects with non-specific subacute and chronic LBP were screened 6 weeks following an episode. Functional tests were bending trunk test, sock test and sit to stand test. Participants performed as many repetitions as possible during 30 s for each functional test. Angular displacement, velocity and acceleration, linear acceleration, time and repetitions were analysed. Participants were divided into two groups to determine their different LBP severity with a k-means clusters according to the results obtained in Roland Morris questionnaire (RMQ). Comparing different severity groups based on RMQ score (high impact = 17.15, low impact = 7.47), bending trunk test obtained significative differences in linear acceleration (p = 0.002-0.01). The differences of total linear acceleration during the Sit to Stand test were significative (p = 0.004-0.02). Sock test showed not significative differences between groups (p > 0.05). Linear acceleration variables during Sit to Stand test and Bending trunk test were significatively different between the different severity groups. RGB-D camera system and functional tests can detect kinematic differences in different type of LBP according to the functionality.

下背痛（LBP）可导致运动控制障碍，这可能是腰痛反复发作的原因之一。了解腰痛评估中与运动相关的障碍，并根据严重程度对患者进行分类非常重要。本研究旨在使用 RGB-D 相机呈现运动学变量的差异，以便对不同严重程度的腰痛患者进行分类。这是一项横断面研究。筛选出在发病后 6 周患有非特异性亚急性和慢性腰痛的患者。功能测试为弯腰试验、袜子试验和坐站试验。每位患者在 30 秒内完成尽可能多的重复动作。分析了角度位移、速度和加速度、线性加速度、时间和重复次数。根据 Roland Morris 问卷（RMQ）的结果，参与者被分为两组，以确定他们的腰痛严重程度不同。根据 RMQ 评分（高影响=17.15，低影响=7.47）比较不同严重程度组，在弯曲试验中线性加速度有显著差异（p=0.002-0.01）。在坐站试验中总线性加速度的差异具有统计学意义（p=0.004-0.02）。袜子试验组间无统计学差异（p>0.05）。坐站试验和弯曲试验中线性加速度变量在不同严重程度组之间有显著差异。RGB-D 相机系统和功能测试可以根据功能检测不同类型腰痛的运动学差异。临床试验注册号：ClinicalTrials.gov NCT03293095“肌肉骨骼病理的功能任务运动学”，2017 年 9 月 26 日。
