Abstract
Background and purpose: Muscle strength is an important index for physical therapists to evaluate on patients. To be able to accurately and quantitatively measure the muscle strength is essential. The purpose of this study was to determine the reliabilities of a hand-held dynamometer in measuring lower extremity muscle strength for normal subjects under specific positions. Method: A convenient sample of 8 males and 7 females was tested using a Power Track II Commander hand-held dynamometer. Muscle strength of 6 groups of muscle was examined with ”Break method”. Results: Intra-rater reliability coefficients were≥0.76 for all muscle groups, except for the dominant hip extensors (ICC1, 1=0.60). The reliabilities were considered to be moderate to excellent. Conclusion: The testing protocol provided in this study seemed to be reliable. Further studies were warranted to determine the inter-rater reliability and validity of these measures in different populations.
