METHOD FOR MUSCLE STRENGTH DETERMINATION Russian patent published in 2009 - IPC A61B5/00 A61B5/22 A61H1/00 

FIELD: medicine, neurology.

SUBSTANCE: strength of patient's anterior serratus muscle (ASM) is measured using balance, on which patient of known weight m₁ stands. His right arm is raised forward, elbow bent, and palm touches his left shoulder. Angle between right arm and body is 90°; right elbow bears against examiner's hand; isometric tension of ASM is exercised upward. In such patient position, right ASM maximum strength m_max of three attempts is registered on the scale. In a similar manner, left ASM maximum strength is registered. ASM strength per 1 kg patient's weight is calculated by expression: . If the values are: right <0.180 and left <0.149, then ASM strength is stated below normal; if the values are 0.352 and 0.359 respectively, ASM strength is stated above normal.

EFFECT: technique allows determination of anterior serratus muscle force.
