METHODS: Cross-sectional study.
METHODS: The strength of 42 muscle groups were assessed with the MST in the bag adaptation and non-adapted methods in 120 healthy individuals, 50 % males, divided into three age groups (20-39, 40-59, 60-79) with 40 subjects per group. Stepwise multiple regression analysis was performed to investigate which independent variables (sex, age, and limb dominance) is the best predictor of muscle strength (α = 5 %).
RESULTS: Sex was the best independent predictor for all muscle groups for both MST methods (8.8 % < R2<57.8 %, p < 0.0001), except for the ankle plantar flexors assed with the non-adapted sphygmomanometer, in which age was the best independent predictor (R2 = 25.6 %; p < 0.0001). The normative values of muscle strength were reported for both MST methods considering the subgroups (sex, age, and limb dominance). Ceiling effect was observed when the MST bag adaptation was used to assess some muscles (8.8 %).
CONCLUSIONS: Sex was the best predictor of muscle strength, as commonly found for muscle strength assessment with the dynamometer. The normative values provided have high clinical utility and can be used to interpret results of muscle strength assessment using both MST methods. For the MST in the bag adaptation method, caution is advised for the assessment of some muscles.
方法:横断面研究。
方法:在120名健康个体的袋适应和非适应方法中,用MST评估了42个肌肉群的力量,50%的男性,分为三个年龄组(20-39,40-59,60-79),每组40名受试者。进行逐步多元回归分析,以调查哪些独立变量(性别,年龄,和肢体优势)是肌肉力量的最佳预测指标(α=5%)。
结果:对于两种MST方法,性别是所有肌肉群的最佳独立预测因子(8.8%
