Low back pain (LBP) is a prevalent condition across cultures, and the tools used for assessment of distinct groups need to be evaluated. Our goal was to investigate the psychometric properties of physical performance tests (PPTs) in a group of Brazilian Portuguese-speaking (BPS) individuals with LBP in a nonexperimental, descriptive study. BPS individuals with and without LBP were studied, and PPTs, self-report questionnaires, and VAS pain score were evaluated. Thirty individuals with LBP (Patient Group (PG)) and 30 healthy subjects (Control Group (CG)) were assessed by 7 PPTs: timed up and go (TUG), loaded forward reach (LFR), 50-foot walk (50 FW), 5-minute walking (5 MW), sit-stand (SS), repeated trunk flexion (RTF), and lumbar flexion (LF). The PG completed the Roland Morris Disability Questionnaire (RMDQ) and the Self-efficacy Scale (SES) and rated their current level of pain by a Visual Analog Scale (VAS). PPTs were highly reliable in the PG with ICC scores ranging from 0.92 to 0.99 (p < 0.0001). The CG performed better in all PPTs but the LFR. In the PG the correlations among the PPT varied from 0.38 to 0.78 (p < 0.05). RMDQ correlated significantly with RTF, SS, 5 MW (0.38 to 0.47, p < 0.05). PPTs were reliable with the BPS patients and able to differentiate groups. RMDQ complements the assessment of these patients.
下背痛（LBP）是一种普遍存在于不同文化背景下的疾病，用于评估不同人群的工具需要进行评估。我们的目标是在一项非实验性、描述性研究中，调查一组使用巴西葡萄牙语（BPS）的 LBP 患者的身体表现测试（PPT）的心理测量特性。研究了有和没有 LBP 的 BPS 个体，并评估了 PPT、自我报告问卷和 VAS 疼痛评分。30 名 LBP 患者（患者组（PG））和 30 名健康受试者（对照组（CG））接受了 7 项 PPT 的评估：计时起立行走（TUG）、负重前伸（LFR）、50 英尺步行（50 FW）、5 分钟步行（5 MW）、坐站（SS）、重复屈伸（RTF）和腰椎屈伸（LF）。PG 完成了 Roland Morris 残疾问卷（RMDQ）和自我效能感量表（SES），并通过视觉模拟评分（VAS）对当前疼痛程度进行评分。PG 中的 PPT 具有高度可靠性，ICC 评分范围为 0.92 至 0.99（p < 0.0001）。CG 在所有 PPT 中的表现都更好，但 LFR 除外。在 PG 中，PPT 之间的相关性从 0.38 到 0.78（p < 0.05）不等。RMDQ 与 RTF、SS、5 MW 显著相关（0.38 至 0.47，p < 0.05）。PPT 在 BPS 患者中可靠，并能够区分组群。RMDQ 补充了对这些患者的评估。
