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

FIELD: medicine, neurology.

SUBSTANCE: strength of iliopsoas muscle (IPM) is measured using balance, on which platform is situated with stool of known weight m₁. Patient of known weight m₂ seats on the stool with flat load of known weight m₃ on his head. His left leg rests on the platform, and his right leg bears against examiner's hand by the knee; isometric tension of IPM is exercised to flex the hip; 90° angle between the hip and the body being constant. Patient's lower leg and hip muscles are relaxed. In such patient position and such force, right leg IPM maximum strength m_max of three attempts is registered on the scale. In a similar manner, left leg IPM maximum strength m_max is registered on the balance, and IPM strength per 1 kg patient's weight is calculated by expression: . If the values are: right <0.169 and left <0.186, then IPM strength is stated below normal; if the values are 0.374 and 0.382 respectively, IPM strength is stated above normal.

EFFECT: technique improvement.
