Objectives: To investigate knee flexor strength deficits dependent on hip joint position in adults with hemiparesis and compare with healthy controls.
Method: a cross-sectional study with ten subjects with chronic (63±40 months) hemiparesis with mild to moderate lower limb paresis (Fugl-Meyer score 26±3) and 10 neurologically healthy controls.
Isometric knee flexion strength with the hip positioned at 90° and 0° of flexion was assessed randomly on the paretic and non-paretic side of hemiparetic subjects and healthy controls.
Subjects were asked to perform a maximal isometric contraction sustained for four seconds and measured by a dynamometer.
The ratio of knee flexor strength between these two hip positions was calculated: Hip 0°-Hip 90°.
