Inclusion body myositis (IBM) is a progressive, inflammatory muscle disease that
is known to cause quadriceps weakness and knee buckling during gait. This is the
first known report of gait characteristics in patients with IBM. Nine subjects
with IBM and quadriceps weakness underwent gait analysis and quantitative
strength testing. A wide range of strength and gait abilities were present in the
subject group. Subjects with stronger knee extensors exhibited nearly normal
sagittal knee kinematics and kinetics. As quadriceps strength decreased,
kinematic and kinetic patterns were increasingly abnormal. Exceptions to this
pattern could be explained by examining strength at adjacent joints. Gait
analysis and strength testing is a helpful tool in evaluating the functional
status of this population and aiding in determination of the needs for
interventions such as assistive devices.
