Abstract:

BACKGROUND: Isometric muscle force testing is a very practical method to measure the contractive strength of muscle or muscle group of subjects’ active movements. It is done by isometric contraction with the joints maintaining in a certain position.
OBJECTIVE: To summarize the research and application concerning technologies of isometric muscle force testing and to discuss the main testing technologies of outlook.
METHODS: Literatures about muscle force testing, isometric muscle force testing and clinical application were searched from ScienceDirect database, HighWire Press database, Chinese Journal Full-text database, and WanFang database by the first author. These literatures have been published from 2000 to 2010 were selected. The key terms were “muscle force, muscle force testing, isometric contraction and isometric muscle force testing” both in English and Chinese, respectively.
RESULTS AND CONCLUSION: Totally 76 papers were initial searched, and 32 manuscripts were included in the review according to inclusive and exclusive criteria. Isometric muscle force testing is to measure the muscle force when one's joints in a fixed angle. It can not reflect the situation of muscle force of human comprehensively, and coupled with the immaturity of testing technology, the application of the test is limited. Isokinetic muscle force testing and isotonic muscle force testing are the main method to test the force of muscle as well. Each of these tests has its advantages and disadvantages. For example, isokinetic muscle force testing can not test the eccentric muscle contraction process, angle-related parameters can not be measured with isotonic muscle force testing system and the surface EMG also has a good effect on assessing muscle force. Therefore, it proposes a new direction for the isometric muscle force testing system to develop that is to combine with isokinetic, isotonic test system and surface electromyogram signal. The combination of the four may bring better test results.
