Introduction[edit | edit source]
Muscle strength stands as a cornerstone of the human body's ability to facilitate both stability and mobility within the musculoskeletal system. As an essential component of the objective examination, the assessment of muscle strength not only sheds light on an individual's physical strength but also offers valuable insights into potential neurological deficits.
When assessing muscle strength, one should consider various factors that can influence the results, including occupation, hand dominance, age, gender, fatigue, medication, and the time of day. These elements can impact muscle strength testing and should be carefully accounted for during the evaluation process.
Occupation[edit | edit source]
Research has demonstrated substantial variations in static muscular strength across diverse occupations.[1] Additionally, findings from a study by Singh et al. (2018) suggest that female handicraft workers may experience occupational stress, resulting in decreased grip strength compared to their counterparts in office-based roles.[2]
Hand Dominance[edit | edit source]
In healthy individuals, the grip strength of the dominant hand is approximately 10% greater than that of the nondominant hand, with right-handed individuals exhibiting more pronounced differences.[3]
Age[edit | edit source]
As individuals age, there is a notable decline in muscular strength, with losses occurring at a rate of approximately 12% to 14% per decade after reaching 50 years of age.[4] Given this age-related decline, health authorities must consider the implementation of strength tests, such as hand grip and leg strength assessments, as screening activities to predict the potential risk of falls and the development of functional disabilities among older adults in the community.[5]
