In clinical examinations of a patient with non-specific low back pain (LBP), there is a need to dispose over a valid and quick to perform rating system. The "Backache Disability Index" for LBP or BADIX includes rating of 5 trunk movements in erect position and a "Morning Back Stiffness" score, whereof the sum gives the BADIX (max. 20 points). The objective of this study was to explore the reliability, responsiveness and concurrent validity of the BADIX. Patients with LBP (n=100) were randomly assigned into a "control" group (n=40) in function of validity studies, and a "treatment" group (n=60) in function of responsiveness studies. The treatment group underwent two weekly sessions of in total 30 minutes of deep cross-friction on the thoraco-lumbar Erector spinae and gluteals. All patients completed the Oswestry Disability Questionnaire validated Dutch version (ODQ), the McGill Pain Questionnaire (MPQ). The impairment examination consists, besides current orthopaedic and neurologic examinations, of the new BADIX scoring system.
In our study the retest reliability after 3 days of the BADIX was perfect (n=039, r=0.95). A good correlation (p < 0.001) was found between BADIX at baseline, and Oswestry Disability Index (ODI) (n=93, r=0.76), and McGill-Quality of Life Index (r=0.74). Similar discriminative ability and effect size of measures was found for BADIX and ODI (n=54). It is proposed that the minimal detectable change should be equal or more than 2 points.
The "Backache Disability Index" appears to be a reliable and a valid assessment tool of morning stiffness and restricted spinal movements, and discriminates between successful and unsuccessful treatment outcome. The BADIX will allow patients to take snapshots of their daily treatment evolution, save them on their computer or tablets (apps) and share the results with their doctors and/or therapists.
在对非特异性下背痛（LBP）患者进行临床检查时，需要一种有效且操作快速的评分系统。用于LBP的“背痛残疾指数”（BADIX）包括对直立位时5种躯干运动的评分以及一个“晨僵”分数，两者相加即得BADIX（最高20分）。本研究的目的是探讨BADIX的可靠性、反应性和同时效度。根据效度研究，将100例LBP患者随机分为“对照组”（n = 40），根据反应性研究分为“治疗组”（n = 60）。治疗组每周接受两次总计30分钟的胸腰段竖脊肌和臀肌深层交叉摩擦治疗。所有患者均完成了经荷兰语验证的Oswestry残疾问卷（ODQ）、麦吉尔疼痛问卷（MPQ）。除了当前的骨科和神经科检查外，损伤检查还包括新的BADIX评分系统。
在我们的研究中，BADIX在3天后的重测信度极佳（n = 39，r = 0.95）。在基线时的BADIX与Oswestry残疾指数（ODI）（n = 93，r = 0.76）以及麦吉尔生活质量指数（r = 0.74）之间发现了良好的相关性（p < 0.001）。BADIX和ODI在鉴别能力和测量效应大小方面相似（n = 54）。建议最小可检测变化应等于或大于2分。
“背痛残疾指数”似乎是一种可靠且有效的晨僵和脊柱活动受限评估工具，能够区分治疗成功与失败的结果。BADIX将使患者能够随时了解其日常治疗进展，将结果保存在电脑或平板电脑（应用程序）上，并与医生和/或治疗师分享。
