A Maximum Muscle Strength Prediction Formula Using Theoretical Grade 3 Muscle Strength Value in Daniels et al.’s Manual Muscle Test, in Consideration of Age: An Investigation of Hip and Knee Joint Flexion and Extension

Abstract

This study attempted to develop a formula for predicting maximum muscle strength value for young, middle-aged, and elderly adults using theoretical Grade 3 muscle strength value (moment fair: Mf)—the static muscular moment to support a limb segment against gravity—from the manual muscle test by Daniels et al. A total of 130 healthy Japanese individuals divided by age group performed isometric muscle contractions at maximum effort for various movements of hip joint flexion and extension and knee joint flexion and extension, and the accompanying resisting force was measured and maximum muscle strength value (moment max, Mm) was calculated. Body weight and limb segment length (thigh and lower leg length) were measured, and Mf was calculated using anthropometric measures and theoretical calculation. There was a linear correlation between Mf and Mm in each of the four movement types in all groups, excepting knee flexion in elderly. However, the formula for predicting maximum muscle strength was not sufficiently compatible in middle-aged and elderly adults, suggesting that the formula obtained in this study is applicable in young adults only.

Cancer survivors exhibit a different relationship between muscle strength and health-related quality of life/fatigue compared to healthy subjects

“…Knee extensor muscle strength has previously been used to assess lower muscle strength (Hayashi et al, 2017;Usa, Matsumura, Ichikawa, & Takei, 2017). Knee extensor muscle strength has previously been used to assess lower muscle strength (Hayashi et al, 2017;Usa, Matsumura, Ichikawa, & Takei, 2017).…”

“…Knee extensor muscle strength (kg) was measured as an index of lower limb strength using a hand-held dynamometer (μ-tas MT1; ANIMA Co., Tokyo, Japan). Knee extensor muscle strength has previously been used to assess lower muscle strength (Hayashi et al, 2017;Usa, Matsumura, Ichikawa, & Takei, 2017). For all measurements, a stabilising belt was used to aid the tester in applying resistance.…”

“…Predicts maximum muscle strength values and explains the relationship between maximum muscle strength values and theoretical Grade 4. Four types of upper limb movement analysis consisted of moment fair on the shoulder joint, moment fair on the elbow joint, moment maximum in the shoulder joint, and moment maximum in the elbow joint [20]. After calculating the theoretical Grade 4 muscle strength value suitable with body weight and upper limb segment length for each assembling treatment, the isometric maximum muscle strength was measured using a handheld dynamometer (HHD) [21].…”

Validity and reliability of isometric knee extension muscle strength measurements using a belt-stabilized hand-held dynamometer: a comparison with the measurement using an isokinetic dynamometer in a sitting posture

“…Findings about the measurement of isometric knee extension muscle strength using a hand-held dynamometer (HHD) are helpful for skeletal muscle function and dysfunction assessment [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] . The gold standard measuring equipment for objective muscle strength assessment is isokinetic dynamometer (IKD) 1) , IKD has been recommended for use in the measurement of muscle strength in the lower extremities 11) .…”
