Considerations and Practical Options for Measuring Muscle Strength: A Narrative Review

Area of Science:

• Kinesiology and Exercise Science
• Gerontology
• Rehabilitation Medicine

Background:

• Muscle strength is vital for maintaining mobility and preventing adverse health outcomes.
• Impaired muscle strength is a significant factor in functional decline across various populations.
• Understanding muscle strength measurement is critical for effective clinical assessment and research.

Purpose of the Study:

• To provide a comprehensive overview of the definition and measurement of muscle strength.
• To describe practical methods for assessing muscle strength.
• To delineate the clinimetric properties of various muscle strength measurement techniques.

Main Methods:

• It synthesizes information on the conceptualization of muscle strength.
• It evaluates different practical approaches to muscle strength testing.

Main Results:

• Muscle strength can be defined and measured through various methods, each with specific advantages and limitations.
• Key clinimetric properties (e.g., reliability, validity) of different strength tests are presented.
• Guidance is offered for selecting appropriate measurement tools based on research or clinical contexts.

Conclusions:

• Appropriate selection of muscle strength measurement tools is essential for accurate assessment.
• Clinicians and researchers can utilize this information to enhance the quality of their studies and patient evaluations.
• Improved understanding and application of muscle strength testing can lead to better interventions for mobility limitations.
