text: Yo, check it out, I got something to say,
  'Bout knee osteoarthritis in a rap display.
  KOA be messin' with your gait, it's true,
  Changin' up them parameters, throwin' off your groove.
  
  Gait variability patterns, they be affected,
  But we got a method to inspect, dissect.
  Uncontrolled manifold, that's the analysis we choose,
  To check the motor control and coordination we pursue.
  
  Walkin' ain't the same for KOA folks,
  Compared to asymptomatic, they face different strokes.
  No research done on gait kinematic change,
  In normal and narrow paths, it's a whole new range.
  
  So listen up, this rhyme is complete,
  KOA and gait, now you got the beat.
  Assessin' multi-segmental movements, we strive,
  To understand how KOA affects the way we thrive.
