Knowledge regarding the reliability of pegboard tests when used to measure dexterity in people with Parkinson's disease (PD) is currently limited.
To examine the test-retest and interrater reliability of the 9-Hole Peg Test (9HPT) and Purdue Pegboard Test (PPT) in people with PD.
Cross-sectional observational study. For test-retest reliability, tests were completed on 2 days, 1 wk apart, in the "on" phase and "end-of-dose" period of participants' medication cycle. For interrater reliability, occupational therapists and physical therapists rated prerecorded pegboard test performance of participants with PD.
Test-retest reliability was determined in participants' homes or in a university department. Interrater reliability was determined in a university department or a hospital setting.
Test-retest reliability was determined with volunteers diagnosed with PD (N = 30). Interrater reliability was determined with a convenience sample of occupational and physical therapists (N = 11).
The 9HPT and PPT are commonly used measures of manual dexterity.
PPT subtests showed higher test-retest reliability (intraclass correlation coefficients [ICCs] ≥ .90) in both phases of the medication cycle compared with the 9HPT (ICCs = .70-.81). Minimal detectable change scores indicated acceptable measurement error for both tools. Interrater reliability for recorded performance of each measure was very good (ICCs > .99), with no calculable measurement error.
Although both tools showed adequate test-retest and interrater reliability, results suggest that the PPT may be a more reliable measure of dexterity loss in people with PD.
This study informs the clinical measurement of the loss of manual dexterity in people with PD, a frequent problem reported by people living with this disorder.
目前，关于钉板测试用于测量帕金森病（PD）患者灵活性时的可靠性的知识有限。
研究9孔钉板测试（9HPT）和普渡钉板测试（PPT）在PD患者中的重测信度和评分者间信度。
横断面观察性研究。为重测信度，测试在参与者药物周期的“开”期和“剂量末期”，相隔1周的2天内完成。为评分者间信度，职业治疗师和物理治疗师对PD患者预先录制的钉板测试表现进行评分。
重测信度在参与者家中或大学部门确定。评分者间信度在大学部门或医院环境中确定。
重测信度由诊断为PD的志愿者（N = 30）确定。评分者间信度由职业和物理治疗师的便利样本（N = 11）确定。
9HPT和PPT是常用的手部灵活性测量指标。
与9HPT（组内相关系数[ICC]=.70-.81）相比，PPT子测试在药物周期的两个阶段均显示出更高的重测信度（ICC≥.90）。最小可检测变化分数表明两种工具的测量误差均可接受。每种测量指标记录表现的评分者间信度非常好（ICC>.99），无可计算的测量误差。
虽然两种工具均显示出足够的重测信度和评分者间信度，但结果表明PPT可能是PD患者灵活性丧失的更可靠测量指标。
本研究为PD患者手部灵活性丧失的临床测量提供了信息，这是该疾病患者经常报告的一个问题。
