To compare hand-held isometric muscle strength measurement to an isokinetic muscle strength measurement in a healthy elderly population.
Cross-sectional survey.
Retirement community in Southeastern Arizona.
Thirty-two volunteers (16 men and 16 women) age 60 and over (mean age 70.3 years) who were free of musculoskeletal problems and did not have significant health problems.
None.
Isometric muscle strength was determined using a hand-held isometric strength device (Penny and Giles) for elbow flexion and extension and knee flexion and extension. Isokinetic muscle strength (average peak torque and average work per repetition) was measured on the same individuals using a Lido isokinetic dynamometer.
Correlations between the strength measurement techniques were generally favorable with the lowest correlation being .72, (95 percent confidence interval .50-.86) and the highest being .85, (95 percent confidence interval .72-.93). However, there was substantial variability of hand-held strength reading at some levels of isokinetic strength.
Hand-held dynamometry for strength measurement correlates strongly with measurement of strength using isokinetic dynamometry. Despite these high correlations, there is remaining variability of hand-held muscle strength readings when compared with isokinetic strength measurement at some levels of isokinetic muscle strength. Modification of the testing methodology or instrumentation used in this study is needed to improve the consistency of these measurements.
在健康老年人群中比较手持等长肌力测量与等速肌力测量。
横断面调查。
亚利桑那州东南部的退休社区。
32名60岁及以上（平均年龄70.3岁）的志愿者（16名男性和16名女性），他们没有肌肉骨骼问题且没有重大健康问题。
无。
使用手持等长力量装置（Penny and Giles）测定肘屈伸和膝屈伸的等长肌力。使用Lido等速测力计对同一人群测量等速肌力（平均峰值扭矩和每次重复的平均功）。
力量测量技术之间的相关性总体良好，最低相关性为0.72（95%置信区间0.50 - 0.86），最高为0.85（95%置信区间0.72 - 0.93）。然而，在某些等速肌力水平下，手持力量读数存在很大差异。
用于力量测量的手持测力计法与使用等速测力计测量力量密切相关。尽管相关性很高，但在某些等速肌力水平下，与等速肌力测量相比，手持肌肉力量读数仍存在差异。需要修改本研究中使用的测试方法或仪器，以提高这些测量的一致性。
