The purpose of this study was to explore the difference in maximal lifting capability between 2 modes of lifting (traditional crate and XRTS Lever Arm) over multiple days. The differences in absolute strength values were compared with existing criteria for sincere effort during distraction-based lifting. In addition, rate of perceived exertion (RPE) is presented for the 2 modes of lifting on each day.
Workers' compensation.
Forty-four subjects between the ages of 20 and 44 years participated in this study. Investigators established 1 repetition maximum (RM) for each subject performing the crate lift. Subjects were randomly assigned 5 weights ranging from 10% to 100% of their determined 1RM and asked to give their rating of perceived exertion after each lift. The same procedure was repeated 2-5 days later using the XRTS Lever Arm. Paired t tests and Spearman's correlation coefficient were used for data analysis. Alpha was set at less than .05.
There was a statistically significant difference (p < .04) between maximal lift values for the 2 lifting modes. The percent difference between the modes of lifting was 10.5% ± 6.4%. In addition, there was a positive correlation between the RPE on the 2 modes of lifting (p = .87).
A functional capacity evaluation (FCE) is typically ordered after the completion of physical rehabilitation and before releasing a patient to full or modified duty. In addition to assessing the ability to function within normal job demands, an assessment of effort by the participant typically takes place during an FCE. Case managers and physicians are presented with information, allowing them to make comparisons between functional lifting abilities displayed during treatment sessions and the FCE. These comparisons may often take place with the subpoena of medical records and may be discussed during the deposition or trial process. If an FCE takes place at a different facility than the physical therapy or work conditioning treatment, 2 different modes of lifting may take place based on the equipment within each facility. The results of this study indicate that the 2 modes of lifting on separate days meet established criteria for lift comparison testing during FCEs.
本研究旨在探讨在多天内两种提举方式（传统板条箱提举和XRTS杠杆臂提举）之间最大提举能力的差异。将绝对力量值的差异与基于分心提举时真诚努力的现有标准进行比较。此外，还给出了每天两种提举方式的主观用力程度（RPE）。
工伤赔偿。
44名年龄在20至44岁之间的受试者参与了本研究。研究人员为每个进行板条箱提举的受试者确定了1次重复最大值（1RM）。受试者被随机分配5个重量，范围从其确定的1RM的10%到100%，并被要求在每次提举后给出主观用力程度评分。2至5天后，使用XRTS杠杆臂重复相同程序。采用配对t检验和Spearman相关系数进行数据分析。显著性水平设定为小于0.05。
两种提举方式的最大提举值之间存在统计学显著差异（p < 0.04）。两种提举方式之间的百分比差异为10.5%±6.4%。此外，两种提举方式的主观用力程度之间存在正相关（p = 0.87）。
功能能力评估（FCE）通常在身体康复完成后且在让患者恢复全职或调整后的工作之前进行。除了评估在正常工作要求下的功能能力外，在FCE期间通常还会评估参与者的努力程度。病例管理人员和医生会收到相关信息，使他们能够比较治疗期间和FCE期间所展示的功能性提举能力。这些比较通常可能会在传唤医疗记录时进行，并且可能会在证词或审判过程中进行讨论。如果FCE在与物理治疗或工作适应治疗不同的机构进行，可能会基于每个机构内的设备采用两种不同的提举方式。本研究结果表明，在不同日期的两种提举方式符合FCE期间提举比较测试的既定标准。
